TasksThere are ten (10) tasks, one for each week: the tasks are detailed below. There is a table to complete for each task. Please fill in the information required. Note: Each resource summary should be around 200-300 words.Week 1The text discusses the elements of modern computing architecture however is largely silent on the individuals who played a role in its development. Find and summarise a resource that describes ONE such individual. The individual should have had a significant influence on the development of computers and/or components of modern computing architecture.MapReduce ApproachReference: Wheeler, D. 2017. [online] Available at: https://www.dwheeler.com/innovation/innovation.html [Accessed 16 Sep. 2017].Link:https://www.dwheeler.com/innovation/innovation.htmlSummary:Sanjay Ghemawat and Jeffrey Dean revealed the massively-parallel MapReduce In 2004, which is a programming model that can be helpful in enabling processing and generates a large amount of data sets with a large collection of parallel machines, even though in an easy programming way. This approach explains that developers “specify a map function that processes a key/value pair to generate a set of intermediate key/value pairs, and a reduce function that merges all intermediate values associatedwith the same intermediate key.” An input reader, a compare function, a partition function, an output writer, and a compare function are being specified by the developers. The output gained is then fed intothe presented framework of the MapReduce that enables the execution of those definitions on the conceivably large distributed collection in order to handle the complications like the failures in the computers or in the networks. It was noted that “many real world tasks are expressible in this model”. The programmers, who are inexperienced with the distributed or parallel systems, can also use the large distributed system using presented model in order to handle the large sets of data. These basics MapReduce approach has been seems to be implemented into different tools like Qt Concurrent and Handoop. Many articles have been proposed after this invention on the strategies to implement MapReduce approaches, one of the examples is Eugene Ciurana proposed article on how to implement MapReduce approach using Mule. This invention was made for the goggle maps however it is being re-engineered even that it is applicable in many projects.Week 2The text discusses the components and activities of operating systems however are largely silent on the individuals who played a role in their development. Find and summarise a resource that describes ONEsuch individual. The individual should have had a significant influence on the writing or development of operating systems.Title: Bill Gates becomes knight but who invented the PC operating system?Reference:Hennigan, M. 2017.Bill Gates becomes knight but who invented the PC operating system?.

Link: http://www.finfacts.ie/irelandbusinessnews/publish/article_1000654.shtmlSummary:The first personal operating system was discovered by Kindall who had a PhD on computer namely CP/M. His thought was that by the development of an operating system applications introduced or created by different manufacturers would be able torun on the same computers. This operating system (CP/M) had been sold very well in the market, which gathered the attention of the IBM. At the same moment the biggest computer company in the world, IBM was looking for an operating system for its personal planned personal computer. 24 years old Bill Gates was visited by the IBMers but he was not able to supply the required system and he directed the IBMers to Kindall in August 1980. Kindall then met the oral agreement with the IBM as he was reluctant to agree to the onerous conditions of that agreement related to non-disclosure and confidentiality. After that on August 28, 1980, the Microsoft made an agreement with the IBM that it will develop the required software for the Personal Computers. Fellow of Gates Bill, Tim Paterson a Seattle resident had been developed QDOS operating system, which was well aware to Gates. QDOS was bought for $50,000. QDOS by the Microsoft, which had the same features as that of the CP/M and later on it was improved by Microsoft and named as DOS. Parts of the QDOS hadbeen copied from the CP/M and were known to Kindall after some time that Bill Gates was cheating on him but even that Kindall just signed license to the IBM rather than taking him to the court as the Software Copyright was in its infancy.
Week 3The Internet didn’t just appear – it was an evolution from earlier networks. Find and summarise a resource that describes ONEof the networks that led to the development of the modern Internet. Title: A Brief History of the Internet & Related NetworksReference: Cerf, V. 2017.A Brief History of the Internet & Related Networks | Internet Society. [online] Internet Society. Available at: https://www.internetsociety.org/internet/history-internet/brief-history-internet-related-networks [Accessed 16 Sep. 2017].Link:https://www.internetsociety.org/internet/history-internet/brief-history-internet-related-networksSummary:Variety of researches had been going-on on the technologies that would be related to the computer networking from since 1960s. The earliest research was consist and concentrated around the packet switching, which is a technique of dividing conversation into small groups or isolated units that is responsible for carrying the address of the respected destination and follows through the network without depending on others. At branching points, computers that are specialized for the task in the network can have the variable path taken by the packets based on the moment-to-moment response to the link failure or network congestion. Paul Baran of the RAND Corporation was the very first pioneer of the packet switching that was emphasized on the methods of network organizing in manner to withstand the nuclear attack. “Paul Baran’s research interest is the likely source of a widespread myth concerning the ARPANET's original purpose”. Without any centralized control system a richly interconnected set of networks had been proposed by, which are the same properties of the today’s internet. Roger Scantlebury and Donald Davies of NPL(National Physical Laboratory) were working on the same research in the UK and coined the term “packet”. Symposium on the OPERATING System Principles was going on for the very first time in ACM (Association for Computing Machinery) in 1967. Then an IPTO program manager, Lawrence Roberts had proposed an initial design for the first phase of ARPANET, which was a design for the packet-switched networkWeek 4Ethernet is an example of a Layer Two (L2) data link protocol that is discussed in the text. Find and summarise a resource that describes the features and uses of ONEother L2 protocol that is not discussed in the text (i.e. NOT Ethernet).Title:Configuring Cisco Discovery ProtocolReference:Support, P., Products, E., Mainline, C. and Guides, C. 2017. [online] Cisco. Available at: https://www.cisco.com/c/en/us/td/docs/ios/12_2/configfun/configuration/guide/ffun_c/fcf015.html [Accessed 16 Sep. 2017].
