Title: Time sharing operating systems

Summary:

John McCarthy (MIT, US) in 1957 started proposing time-sharing operating systems, where more than one user have the access to share a single computer believing that the control of the entire computer is in their hand multiple. John McCarthy wrote a memo to Professor Philip Morse  on first January 19589 in which he proposed that this could be implemented into the future technologies or machines, which increased the excitement in the computing field and attracted many researchers towards the same topic. Christopher Strachey of National Research Development Corporation, UK, wrote an article on the same topic, “time-sharing in” in which he proposed that the notion that ‘programs share the computer’ and cannot introduced that users can also share the same computer in 1959, which made the article worth nothing. At that same time programs were already sharing the computers in the SAGE project.  Since 1961 Fernando Corbató, who was from same MIT, invented a four-terminal system that was working on the mainframe of IBM 709. After so many researches, experiments and proposed theories, these inventions became challenge for the researchers and the first effective running time-sharing system was proposed namely, “Compatible Time Sharing System (CTSS)” which was a completely working system. These mechanisms are still the critical support for the computer security of some of the computers of this time too, either are able to share the different users mechanism or not.

Title: Bill gates influencing windows operating system

Summary:

Bill Gates

Bill Gates was appending too much time with computers after when he was graduating from the high school and enrolling to the Harvard College in 1973. By 1975 he wanted to start his own computer software company and was successful in owning his own software company with his friend Paul Allen after reaching an agreement with MITS (Micro Instrumentation and Telemetry Systems) in manner to develop a BASIC interpreter for the Altair 8800 computer. After a year they register their company under named ‘Micro-Soft’ in 1976 after ending his studies at Harvard.

IBM in 1980 offered him if he would write BASIC interpreter for their soon-to-be release IBM personal Computer, which resulted in breakout for him that took him to a great success. Same time IBM mentioned that they were also need an operating system for their computers. Few offers had been made by him and for various reasons they did not work out this resulted him an offer to produce one for them. After that he proposed Seattle Computer Products with an offer of with exclusive agreement and ultimately ownership for the developed computers in exchange of the operating systems that they owned already namely ’86-DOS’. The agreement was made successfully and the market was boomed with a new technology with very big profit with the leading player in the computer industry for Microsoft. After agreeing the contract with the IBM Microsoft launched Windows in 1985 and asked IBM to supply operating system OS/2. And after that everyone is still well introduced with the Microsoft and using it in their personal computers.

Week 3

The 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 Networks

 Summary:

A research program initiated by U.S. DARPA (Defense Advanced Research Projects Agency) (DARPA), which was started to investigate the technologies and techniques for interlinking the different types of packet networks in 1973. The main purpose behind the research was to develop communication protocols that would be able to make networked computers in order to communicate transparently across the various linked packet networks. The project was named ‘Internetting project’. This led to the birth of the ‘Internet’ and produced an asset for this new age where every individual is well informed and using in their daily life. Throughout the whole process a system of protocol was developed, which became to be known as Transmission Control Protocol (TCP) and Internet Protocol (IP). Nowadays the major backbone of the internet communication service has been because of the development of NSFNET by the NSF (National Science Foundation) in 1986. Between the networks NSFNET links per month recorded is to be order of 12 billion packets with its 45 megabit per second facilities. The U.S. department of Energy and NASA (National Aeronautics and Space Administration) has been contributing to this technology and providing additional facilities in the form of ESNET and ESNET respectively. Hundred thousands of the computers are being connected to the networks by the connectivity facilities provided by the major international backbones like NORDUNET in Europe and helping them to connect with their loved ones and through the whole world. After that evolution or invention only we are able to get the internet and connecting to each corner without any obstacles and collection necessary information.

Week 4

Ethernet 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 ONE other L2 protocol that is not discussed in the text (i.e. NOT Ethernet).

Summary:

ARCNET is another example of the Layer-two protocol that is enabling and enhancing towards better experience of the networking for the individuals that are connected via networking. ARCNET (Attached Resource Computer Network) uses a token-bus scheme that can be applied in order to manage line sharing among the devices connected on the LAN and among workstations and is a widely-installed LAN (Local Area Network).In other words it can be said that it is a communication protocol for the LANs. It became popular in 1980s for automating the tasks related to work, and was the first widely available networking system for the microcomputers of that age. Technically, empty message frames continuously being circulated on a bus by the LAN server. A “token” is being inserted when a device tries to send the message in an empty frame and on that it also inserts the message. After the message is read by the other device it again resets the token at 0 so that it can be used again by other devices. Since all the devices are afforded the similar opportunities in order to use the network features that have been shared, it results in better efficiency whenever the traffic increases. When the destination device or LAN server reads the message, it resets the token to 0 so that the frame can be reused by any other device.  There are various applications of ARCNET, which can be listed as: Motor Drives, HVAC, Data control and acquisition, office automation, power generation shipboard automation and many more that are helping in enhancing the experience of the network of each individual.

While information systems and technology deliver many benefits to society, they can also result in (sometimes inadvertent) negative effects and outcomes.  Find and summarise a resource that describes ONE example of where the use of an information system or technology has led to negative consequences for humans.

Title: What is WannaCry and how does ransomware work?

 Summary:

Information technology is increasing in rapid manner, which led the technicians to put more emphasis related to the information security, which is also speeding up as the technologies are. WannaCry ransomware cyber-attack is a very recent example of information security failures. This cyber-attack causes serious loss to several organizations and it was a very mass destruction attack in which hundred millions of computers were affected globally. This breach was possible because of two reasons; first failure of U.S. agencies in keeping their ‘EternetBlue’ software and other fault was the users less precautions over the information security. These both reasons cause loss to common people as well. No one is taking any type of precaution while feeding and saving their data into the database, whether they are saving it online or using any offline means. This virus spread all over the internet and coding was so special and unique that several IT researchers were not able to decode it. Many of the organization had to pay the ransom in exchange of the anti-virus and face a serious loss. The hackers had targeted several big organizations and hospitals and made good money from them. Maximum damage was made to the systems that were using pirated or old version of operating system. Although the damage was big and after that everyone is taking precaution but this could not change what had happened. Every individual and organizations should learn from this incident and focus on information security before implementing information technologies into the system.
