Student Name: Learner Authentication Statement If you copy from someone else or allow another candidate to copy from you, or if you cheat in any way you may be disqualified from at least the assignment concerned. Any help or information you have received from people other than your subject teacher must be clearly identified in the work itselfAny books, information leaflets or other material (eg videos, software packages or information from the internet) which you have used to help you complete this work must be clearly acknowledged in th e work itself. To present material copied from books or other sources without acknowledgement will be regarded as deliberate deception. Declaration by learner I have read and understood the above statements. I have produced the work without help except for help from my subject lecturer and the help which I have declared in the work itself. I have acknowledged all source material in the work itself.Write suitable materials for Chapter 1, section 1 which explains the purpose and workings of basic communication devices and the principles of signal theory. Task 1b M1 Explain techniques that can be used to reduce errors in transmissions Add a section 2 to your guide (entitled ‘Error detection and correction’) which explains the techniques that can be used to reduce data transmission errors. Task 2 and grading criteria covered TASK 2 P3Describe communication protocols used and explain why they are important D1Critically compare the OSI seven layer model and the TCP/IP model W rite section 3 (entitled ‘Communication protocols’), which should include a description of the communication protocols in common use and explain why protocols are important.Write a detailed comparison of the OSI seven layer model and the TCP/IP model, commenting on the approach taken and the suitability of each of the models. Guidance notes THIS ASSIGNMENT IS VERY MUCH ABOUT EXPLAINING THE BASIC THEORY THAT LIES BEHIND COMMUNICATION TECHNOLOGY. THERE ARE LOTS OF SOURCES FOR THIS INFORMATION IN BOOKS AND ON THE INTERNET, BUT REMEMBER WHAT YOU WRITE MUST BE IN YOUR OWN WORDS; YOU CANNOT COPY MATERIAL DIRECTLY FROM THESE SOURCES.For Task 1a you will need to list the various types of communication devices and explain how they are used. Note that the unit content makes a distinction between ‘general’ communication devices, network components (servers, workstations, NICs, etc. and interconnection devices (hubs, routers, switches, etc. ). For this task (covering P 1) you should be describing general communication devices, not specific components which are covered in Assignment 3. In practice, it might be quite difficult to make this distinction, but don’t spend too much time describing network components in this assignment. In terms of communication devices, the unit content mentions wired devices, such as DTE devices (e. g. , a computer) and DCE devices (such as a modem), and wireless devices (such as mobile phones, PDAs and laptops, etc. ). You need to explain in outline the way these devices can be connected to a network.To cover P2 an explanation of digital signal theory is required. Refer again to the unit content to see the issues you must cover. For Task 1b you need to write an explanation of the techniques used for error reduction. The only technique mentioned in the unit content is checksums, but other simple techniques such as parity might also be covered. For Task 2 an explanation of what protocols are, why they are importan t and examples of ones in common use are required. To achieve D1 you will need to write a detailed comparison of the OSI and the TCP/IP models. This will need to point out the similarities and differences between the two models.

Subnet11 Assignment 8. : The theory of data communications I recently just got a job as a junior technician at NetCo; NetCo is a company that manufactures networking hardware such as switches, routers, etc†¦ They’re planning to start up a networking academy (rather like the Cisco Network Academy) and create related qualifications. The project manager has approached me so as to prepare some learning materials for ‘Chapter 1’ of the online course. Chapter 1 is entitled ‘The Theory of Data Communications’. The chapter will be subdivided into a number of sections. And I’ve decided that t he materials shall be produced in the form of a Word document. Chapter 1 Section1Identify and explain types of communication devices There are different types of communication devices; Communication devices are electronic hardware that interacts (communicates) with each other to perform specific tasks. The technologies that are used to communicate are data terminal equipment (DTE) and data circuit-terminating equipment (DCE). Another type of communication devices would be Wireless devices. I plan to explain all the above in detail. Data Terminal Equipment (DTE) DTE is a form of expression for a device that is at the end of the line. Examples of this could be a modem, network interface card (NIC), mobile phone or Bluetooth.DTEs differ depending on its purpose, for example, with Bluetooth, size and range are an important feature and with mobile phones, the quality and bandwidth are more important. Network cards and modems exist in a range of formats that are designed for a wide range of speeds i. e. bandwidth depending on the type of network being used. Data Circuit-terminating Equipment (DCE) DCE and DTE work together by the DTE connecting to the Internet or network service offered by the DCE. This is network equipment which controls the communication. Some examples of these are: †¢ A Bluetooth dongle in a PC, which is used to synchronise a mobile phone or PDA. †¢ A switch in a communications/server room at school, college or work, which will connect all the computers to the Local Area Network (LAN) and the InternetWireless Devices Wireless devices are devices which transmit their data over the air. Types of mobile communication devices would be third (3G) and (2G) group of mobile phones, wireless laptops and wireless PDAs. Wireless networks use the 802. 11x standard. This is the IEEE standard (Institute of Electrical and Electronics Engineers) which defines the speed of the network and its range. The mobile phone network is a large connection of stat ions throughout the nation and internationally which allows subscribers to the service to communicate through low bandwidth voice system. The principles of signal theory Data The smallest portion of data is a bit.The word bit comes from Binary Digit which is either a 0 or 1. 0 or 1 means Off or On. This controls hardware within communication devices to perform operations. When bits are grouped together the can become more useful. For example, 8 bits of data will form 1 Byte. Denary to Binary Denary means 10 numbers. In our standard number system we have 10 numbers. These are: 0,1,2,3,4,5,6,7,8,9. Now to convert Denary to Binary, you must know the base 2 rules. These are similar to units, tens, hundreds that primary school children are taught. So for example say†¦ I want to convert the denary number 37 into binary. I would do this by taking the number and dividing it by 2 each time: Divide by 2 |37 |Remainder | |Divide by 2 |18 |1 | |Divide by 2 |9 |0 | |Divide by 2 |4 |1 | |Div ide by 2 |2 |0 | |Divide by 2 |1 |0 | | |0 |1 | Now what I do is take the remainders from the bottom of the table going up: 100101. With this I will now do 2 to the power of X, X being 0,1,2,3,4,5,6 etc. 25 24 23 22 21 20 – This is the 2x 1 0 0 1 0 1 – This is the binary for 37 32 16 8 4 2 1 – This is the base 2 ruleNow to check that the binary is correct I will take the base 2 numbers where the binary is a 1 and add them together. I should get the denary number: 32+4+1=37 This is how denary is converted to binary. Data Packets In networking, data must be formed in a package to be able to be transported over a network. Package formats vary for different types of networks. However the term data packet is always used to describe a package. A packet will contain a minimum of the foundation address, the destination address, data and error control. The foundation address is sent so the destination knows who sent the data. The destination address is used to find the r ight destination.Data is the actual information being sent. Error control is sent to help identify problems with the data once it has arrived at its destination (see chapter 1b for error detection techniques). Asynchronous and Synchronous Transmissions Asynchronous transmission means that the receiving device must accept the receipt of data before the source device will send more data. In synchronous transmission, both devices will synchronise with each other before any data is sent. Bandwidth (Analogue) Analogue signals are sine waves which look like the waveform in image 1. Sine waves are known as analogue signals is because they are an analogy of sound waves which travel in the same way.Analogue bandwidth is the number is cycles that occurs with the sine wave over a period of time, for example in image 1, the wave is 1Hz and occurred within 20ms so the bandwidth is 1Hzpms (1 Hertz per millisecond). So, finally, the bandwidth of an analogue signal is the difference in frequency be tween the highest and lowest frequencies contained in the signal. Bandwidth (Digital) Digital bandwidth is different to analogue bandwidth because digital signals are either 0 (off) or 1 (on) and look like squares (see image 1. 2). Digital bandwidth is the quantity of data that can be sent through a transmission over a specified period of time. These are generally measured in Bits per second (bps), Kilobits per second (kbps), Megabits per second (mbps) and Giga bits per second (gbps).Section2 Error detection and correction Parity (Odd and Even) Even  Ã¢â‚¬â€œ Parity checking is usually used for Bytes of data. A parity bit is added to every Byte of data transmitted, whether the ninth bit is ‘0’ or ‘1’ depends on the combination of the other eight bits. If there is an uneven number of ‘1’s then the parity bit will be a ‘1’, if there is an even number of ‘1’s the parity bit will be a ‘0’. There should alway s be an even number of ‘1’s in the data. For example: 1011001 Parity bit = 0 Odd  Ã¢â‚¬â€œ This works the same way as even parity checking, however, instead of the ‘1’s equalling an even number, they should equal an odd number.For example: 1011001 Parity bit = 1 Parity checking is easy to apply and can detect errors, however, it cannot correct errors, therefore, if an error is detected the data would need to be transmitted again. This method does not always work, this is because only an odd number of bits in error can be detected, if there is an even number of bits but there is still an error, this will not be detected. For example: 1011001 could be transmitted as 1100011. This is not the way that the data should have been transmitted but the error would not be detected because the data has an even number of bits in error. Cyclic Redundancy Check (CRC) Cyclic Redundancy Check is an error-detecting system. It performs a long division equation where the ans wer is thrown away and the remainder becomes the result.The data is then transferred and the same equation is done at the other end, if the remainder of the equation isn’t the same as the receipt, the data is corrupt and therefore rejected. Chapter 2 Section3 Communications Protocols Hyper Text Transfer Protocol (HTTP) Hyper Text Transfer Protocol is a set of rules that order the distribution of information over the internet. Its use to retrieve hypertext documents, which are interlinked text documents, led to the development of the World Wide Web. HTTP is a request and response made by the client and server, the client being the end user and the server being the web site. A client that makes a HTTP request using a web browser is known as a User Agent.The server, which stores resources such as HTML files or images, is called the Origin Server. Between the User Agent and the Origin Server may be intermediaries i. e. a negotiator who acts as a link between parties and examples are proxies, tunnels and gateways. HTTP is not controlled by the TCP/IP model and is the most popular application on the internet. Transmission Control Protocol/Internet Protocol (TCP/IP) The Internet Protocol Suite (or TCP/IP) is a set of protocols for communication used for the internet and similar networks. Its name derives from the two most important protocols in it, Transmission Control Protocol (TCP) and Internet Protocol (IP), which are the first protocols in the Internet Protocol Suite standard.The Internet Protocol Suite may be viewed as a set of layers that work together in the transportation of data from one place to another. The TCP/IP model consists of four layers, from lowest to highest they are the: †¢ Link Layer †¢ Internet Layer †¢ Transport Layer †¢ Application Layer File Transfer Protocol (FTP) File Transfer Protocol is a protocol that is used to transfer data from one computer to another computer or device. FTP is a protocol for file transfer which allows the transfer and change of files over a TCP network. A FTP client connects to an FTP server and the client can then make changes, add or delete files on the FTP server. An example of an FTP client would be the webpage upload feature on Microsoft FrontPage.FTP has been designed so files can be transferred to any FTP server regardless of operating system type or version. Open Systems Interconnection (OSI) The Open Systems Interconnections Basic Reference Model (OSI Reference Model or OSI Model) is a description for layered communications and network protocol design. This was developed as part of the Open Systems Interconnection intelligence. Basically, network architecture has been divided into seven layers. From top to bottom, these layers are: †¢ Application †¢ Presentation †¢ Session †¢ Transport †¢ Network †¢ Data Link †¢ Physical This is known as the OSI Seven Layer Model. Each layer is characterized by their formation. These provid e services to the layer above and receive services from the layer below it.An example of this would be a layer that can provide error free communications across a network provides the path needed by applications above it. It then calls the next layer below it to send and receive packets that make up the contents. Comparison between the OSI seven layer model and TCP/IP model OSI Seven Layer Model The OSI Seven Layer Model is a model for data transfer through layered communications allowing data from one PC to be able to be read by another PC anywhere in the world. This model packets the data into many layers, an example would be the layers of an onion, so it then transfers itself to another computer where it goes through the same seven layers but in the opposite direction to unwrap those layers.See image 6 for the structure of an OSI Seven Layer Model. These layers don’t communicate across to their ‘doppelganger’ layer on the other computer. If they wish to commun icate, they have to go through all the other layers that stand between them and their ‘doppelganger’ layer. This table to the right is basically explaining what each layer’s job is. (Table obtained from www. humanreffence. com under the download section) TCP/IP Four Layer Model The TCP/IP model captures data to provide idea of protocols and services. Data is captured in the same way as data is within the OSI Seven Layer Model, so data has to be captured on each level in the same way.The OSI Seven Layer model and the TCP/IP model are both similar in that they both use layers to perform tasks. They also have 2 layers that are very similar, the Transport and Network layers. The TCP/IP internet protocol suite has a wide range of protocols working at each layer of the OSI and TCP/IP models. Critical Comparison OSI and TCP/IP are both similar in a few ways, these being that they both work with layers to communicate, they are both a set of rules and they were also devel oped alongside. The Session Layer (OSI) In the OSI model, the Session layer allows two devices to hold on going communications called a session across a network. This is not found in TCP/IP.In TCP/IP, these characteristics are found in the Transport layer. The Presentation Layer (OSI) In the OSI model, the Presentation layer handles data format information for communications across a network. This is done by converting the information into a common format that both sides can understand. This is provided by the Application layer in the TCP/IP model. The Application Layer (OSI) In the OSI model, the Application layer is the top most layer of the model. It provides a set of interfaces for applications to gain access to services within a network as well as access to network services that support applications directly e. g: OSI – FTAM, VT, MHS, DS, CMIP TCP/IP – FTP, SMTP, DNS, SNMPAlthough the idea of an application process is common within both, their approach to the task of constructing application entities is very different. How OSI builds up applications OSI demands that distributed applications operate over a strict hierarchy of layers and are constructed from a tool kit of standardised application service elements, making them compatible. How TCP/IP builds up applications In TCP/IP, each application is created on whatever set of functions it needs beyond end to end transport to support a distributed communications service. Most of these processes build upon what it needs and assumes that only an underlying transport method (such as a datagram or connection) will be provided. Transport Layer (OSI)In OSI, the Transport layer takes the data that is going to be sent and breaks it down into individual packets that are sent and then reassembled by the Transport layer at the destination. It also provides a signalling service which tells the sender that the destination had received the data has been successfully received. Transport Layer (TCP/IP) In TC P/IP, the Transport layer introduces two transport protocols, TCP and UDP. TCP implements reliable transportation of data whereas UDP doesn’t. The reason this is, is because TCP required acknowledgement to ensure that data is sent correctly and successfully. If an error is detected, the packet can be resent. UDP just broadcasts the data without any need for a reply from the destination therefore data transportation will be faster but will be less reliable as errors can occur.Comparing Transport for both Models Transport for both models is very similar as they both contain transfer protocols that required acknowledgement that data has been received by the destination. While this would be slower, this is more effective as data will always end up being sent correctly. Network Vs. Internet. Both OSI and TCP/IP support a connectionless network service. OSI’s CLNP is practically identical to the Internet’s IP. Both are best-effort-delivery protocols. They are virtuall y identical but the one major difference that sets them apart is that CLNP supports variable length addresses whereas IP supports fixed, 32-bit addresses.

Development of Curleys wife throughout the novel Essay

In the novel Steinbeck’s uses social class, to separate the characters from one another especially Curley’s wife from crooks â€Å"you keep your place then nigger†, indicates to us that the social structure was different in America around 1937, a white women was above a black man. The writer showed this and showed peoples attitude of time. In addition it also gives us an insight on how it will feel like to be black.  Furthermore Steinbeck’s also describes Curley’s wife in a desperate and worried way â€Å"married two weeks†¦Ã¢â‚¬ ¦?† this is shown by the writer creating a tone to the quote, ending the quote with a question mark could mean that the other characters are confused to whether it would last or not, in addition it could also signify that they are doubting their relationship. Steinbeck’s use of language starts to develop more, when he goes on to describe Curley’s wife on page 53. The writer describes her in a sexual dangerous way; we know this by the writer repeating the word â€Å"red†. This indicates to us that danger awaits her; additionally it could also mean that she is seen as a â€Å"sex image†, by the other men on the ranch. This is shown by the writer using the term â€Å"fascinated†, which describes how the other men felt when they saw her. Furthermore, her body languages links to how she’s speaks, â€Å"her voice had a nasal, brittle quality† this indicates to us that she had a fragile slow voice that hypnotized men which made her sound innocent â€Å"Lennie watched her†. This quote enhances that men couldn’t keep their eyes off her, the writer makes Curley’s wife out to be a advert, says things slowly in a tempting way, portraying her as an object. In addition the writer describes Curley’s wife as a desperate insecure women that feels the need to seek attention from other men, â€Å"her body was thrown forward†, specifies to us that she is pushing herself to the situation. In the novel, Steinbeck makes the role of women in the book all to do with sex, some providing sex for the men, portraying them as sexual objects. However, some female characters are seen as either mother figures. This is in contrast to Curley’s wife which is seen as a women who keeps degrading herself â€Å"Curley’s married a tart† this enhances to us that the men on the ranch have no respect for her, this is shown by referring to her as a â€Å"tart† which could also include how the way she dresses in a sexual seductive way to cover up her insecurities. However Curley’s wife may want to dress up because it makes her feel good about herself and she does have the time since her husband is quite wealthy. Moreover, in the novel Of Mice and Men, the writer John Steinbeck makes it out to be women are inferior to men, this is shown by making Curley’s wife the only women on the ranch. Furthermore, the writer also describes Curley’s wife in a detailed sympathy way and this makes the writer feel sorry for her â€Å"you better go home now†, indicates to us that Curley’s wife is in a place that she is not meant to be, it also shows how isolated she is, this is shown by using the term â€Å"quietly† which shows to us that she is being sneaky about the situation, furthermore it also shows us that she isn’t allowed to communicate with other men which gives us an insight about her, that she doesn’t have any friends on the ranch, she has to do it discretely, this shows that Curley doesn’t trust her and she feels protected in the hands of the other men on the ranch, this creates a sense of security. Furthermore, the writer John Steinbeck’s in a way describes Curley’s wife as a dog, metaphorically speaking â€Å"bitch please†, which shows to us that she is described as female dog, rather than a human being which implies to us that she is not an important person, which links with Candy’s dog, which both have something in common, they both died. In addition when they are described or mentioned in the book John Steinbeck’s makes it sound like they are the subject or object in the sentence. It also shows the insignificant in both characters.

Description for the map Essay Example | Topics and Well Written Essays - 750 words

Description for the map - Essay Example The next step was deciding on the ratio of water to land to be used for the map (Berger 12). Since it was a small map, I indicated portions of rivers and few ponds using blue color. However, the brown and green colors indicated the land. The other step was considering the kind of features to put on the map. It was a geographical map and, therefore, I included a wide range of features using different colors. You can identify some mountain ranges, green forest, deserts, and valleys on the map at a glance. The final step was thinking about the weather patterns. You can observe that the large part of the map is drawn using brown color while the other one is in green color. The brown color represents the desert areas while the green color represents the rainy areas. You can, therefore, determine the kind of climate and environment found in different areas of the map. Mongolia region is a kind of place that I would like to visit. I got curious and decided to do some research about the region. I found that Mongolia region is located in China as one of the largest Chinese province. It has many ethnic groups but is not very populated. The climate is different, during the year it has long cold winters and short summers. In addition, Mongolia region experience arid climate to the west and semi-humid climate to the east. The annual rainfall increases from west to east (Monmonier 63). My research about Mongolia region created a beautiful image about the region, which I attempted to express using a map. The eastern part of Mongolia region seems to be evergreen since it experiences semi-humid type of climate (Berger 73). Everybody would like to visit such a region and enjoy the beautiful vista of the green environment. The environment seems to attract different kind of animals that enjoy grazing along their beautiful paradise. The map presents a number of rivers in the eastern part of the region. This

Mother Challenge Personal Statement Example | Topics and Well Written Essays - 500 words

Mother Challenge - Personal Statement Example Texting for me, is my primary source of communication. I rarely actually talk on the phone and my daily schedule is so hectic that I don't have many opportunities to meet up with my friends. Usually, as I am going about my daily routine, I receive a text message from a friend, pause for a moment and text back. It is a quick and efficient way of catching up with people without any inconvenience. I found that when I stopped texting I had relied upon it way too much. Not being able to text felt like living in a vacuum. To be completely honest, if I had not had to deal with roaming charges, I probably would not have been able to do this assignment. As for not using the computer, well I failed that one. I struggled for one day without using it and concluded that society never really existed until the computer age. I could not live without my computer. I did however, make a concerted effort to reduce my time on the computer. The computer is such an integral part of my life that I really cannot accomplish much without it. Likewise for the television. I never realized how much television I watch. It too, is part of my daily routine and even if I am not sitting and watching it, it is still always on. I never noticed that life takes place outside of my windows because I always have the TV blaring. I even fall asleep at night watching TV.

Neuro linguistic programming (NLP) Essay Example | Topics and Well Written Essays - 500 words

Neuro linguistic programming (NLP) - Essay Example Identify the submodalities relating to this belief. Identify internal representation and internal feeling of it. Identify a belief that you are unsure about in your life and explore this internally. Contrast the differences between the unwanted belief and the unsure belief. Test each submodality that you’ve worked out as being different by exchanging the submodality relating to the negative belief with your unsure belief. Change each one back to the way that it was before moving on to test the next one. Ask yourself what new liberating belief you would like instead of the old one. Identify this positively and that it is something you really want rather than what you feel you should want. Look at how this new belief will affect others around you. If needed, make slight changes in your wished for belief to account for this. You are now ready to change your negative belief to the way you feel about the unsure belief. Leave the content the same, change one or more of the most powe rful submodality differences you discovered in step. Change the content of the old belief to the new belief using the submodality shift. You can move your perception of the old belief away and replace it with the new wanted belief. Test by checking that your new belief is automatically represented by the new submodalities and check for the feeling you were aiming for. The six Representational Systems recognised in NLP are Visual (sight), Auditory (hearing), Kinesthetic (touch, physical bodily sensations including emotions), Gustatory (taste), Olfactory (smell), and Auditory-Digital. Mission Statements are the inspiring words chosen by successful leaders to clearly and concisely convey the direction of their organisation. A clear mission statement is able to communicate intentions and motivate the person to realise an attractive and inspiring vision of the future. Though, a personal mission statement is a different from a

Knowing Your Audience Paper and Communication Release Essay

Knowing Your Audience Paper and Communication Release - Essay Example The aftermath of the collapse was entrapment of over thirty workers at a depth of three hundred meters deep. This meant inadequate basic needs such as water, food and oxygen, a situation that downed the hearts of their relatives whose hope died after four days with their husbands, fathers and brothers trapped in a mine. New York Times (2011) asserts that there has never been such a scenario where, miners would survive after a long period trapped underground. However, the supply of food that started for two days would subsequently run into weeks after the establishment that the miners were still alive and intact. Additionally, a second collapse of one of the other remaining shafts destabilized the rescue process by making the process even more difficult. The news f this collapse spread throughout the world like a bush fire with many fearing that the miners will not last until their rescue. However, it was astonishment instead of cries when after seventeen days the first contact was ma de to the miners only to find that all the miners were safe and in a good condition. Initially, it had been, communicated to them that it should take the rescue team almost four months to rescue them onto the surface. However, at the fall of 69 days, the first miner of \all the miners who had been trapped were brought to the surface exceeding effectively (Weik, 2010). Given the fact that communication must be designed with a particular audience in mind, and there are a number of considerations to be observed. This is, in addition to, needs of the potential receivers of the information. Therefore, it is noteworthy that the person relaying the information understands the recipient, and use a proper communication, tone and even information message caries. This will enable appropriate delivery of the message, which will ensure that the audience understands, and clear doubts about any confusion (New York Times, 2011). Therefore, the company has to communicate to different people, and the se include the family, other employees and the press. Any wrong word is sure to create panic especially to the family members, and this makes family essentials extremely valuable, and, therefore, taken into grate consideration. There are certain needs of the family that have to be met to ensure their peace of mind. However, it is noteworthy that few companies have appropriate preparations for such situations, and use of addressees to convey the message. This one of the hard times in the Mining Company, for it had a hard time keeping the families of the trapped miners reassured. Ability to maintain the staff tranquil and at peace that the Chilean Copper Mining Company was doing everything to get the miners out, was their top priority. It is noteworthy that the company had an already established way of keeping the families, the local community and the other employees of the trapped miners. During this entire time of rescue efforts, the relatives of the trapped miners should have recei ved some counseling while praying for beneficial outcomes, but also being prepared for the worst. All information obtained by exerts during the process should have been shared at a gathering of family of the trapped miners with grief counseling making the necessity of the sessions of briefs. This means that the family should

The most Important Legacy of Reformation for us Today Essay

The most Important Legacy of Reformation for us Today - Essay Example The protestant reformation started in Europe in the early sixteenth century1. The works of Martin Luther King’s activities that he carried out in the late fifteenth century informed the reforms. During such times, it was evident in the Roman Catholic Church that the pope had the powers to sale of penance letters to people following the fact that he was deficient of the authority to forgive sins. In those days, the priest was highly regarded more important than any other person. Therefore, anything that he did was highly regarded as of moral right and was subject to no rejection or question. In this regard, the Catholic Church considered priests more than other considered other people. Following the ever questionable issues noticed by Luther regarding the practice of the pope, Luther advocated for provision of the Bible to everyone to read for themselves. It is due to such ill beliefs and practice that forced Martin Luther to call an end to such practices. He gained many follow ers in various countries by inspiring many religious reformers to break away from the Catholic Church and develop their own ideas. ... The reformations led to various religious wars that was termed the Thirty Years War. Christians believe in the ability of God to forgive sins since he has the power to do so. However, the notion that a person can influence God to forgive another is misleading. It is the idea of forgiveness of sins as well as the massive power accorded to the pope that led to the call to reformation. Reformation is an important aspect of human life. It is of crucial importance to highlight that different reformation always follow quests of justice with regards to certain matters that affect humanity. As such, people may always engage in protests with the hope of correcting a wrong where necessary. Such issues that always bring notable protests that mark the beginnings of reformations always arise from several sources. A major factor that may push for reformation may involve political factors. This may be evident where certain issues are considered oppressive to the general wellbeing of humanity. In ad dition, several protests championing for reforms may follow differences in religious views. As such, several religious societies may collude and strongly oppose a wrongdoing that may be evident in the society. Major reformations in history came with regards to the Roman Catholic church. The church in earlier days had several provisions and guidelines hat majority of followers considered oppressive. Such did not marry well with their beliefs and the faith they had in Christianity. Majority of such issues were being steered forth by the people of high ranks in the church. Such issues were considered oppressive to the faith and beliefs that were maintained by the faithful. This brought forth major reforms in
