...? History and Impact of Computing Introduction The term computer initially meant a person proficient in performing arithmetical calculations using a mechanical computing device. The basis of computers development was set back in the era before Christ. The history of computers dates back to the 1640s following the development of a mechanical arithmetical machine. The history of computer advancement is frequently used to refer to the various generations of computing devices. There were five main generations of computers with each generation characterized by a crucial technological...

Newcastle College- Virtualisation Technologies

.... After that, purchase of hardware, accessories and implementation of the system follows. Implementation was done according to the plan that was developed at first. Successful implementation is followed by management of the system. In that case, the system is checked whether it is operating well and trouble shooting any issues that maybe experienced. The four phased methodology is one of the best ways of approaching such project as it takes into account all issues that may cause future challenges. New Castle College used a number of virtualisation systems creating hybrid cloud solution. This is advantageous because the system can operate to some extent on one of the...

Social Issues in Computing

...SOCIAL IMPACT OF GROWTH OF COMPUTERS AND INTERNET IN DEVELOPING COUNTRIES Introduction Social issues in computing essentially entail discussion of ethical use of computers in society to include aspects such as privacy, intellectual property rights and the impact of computers on society at large. Social responsibility also includes accountability of computer managers to serve the goals of society. The growth of internet is now considered essential and is set to bring about greater productivity, governance, education, health and quality of life reforms particularly in the rural areas in developing countries causing all round socio-economic development. (Madon: 1999). However this development is not merely a function of technology... , which...

Current Issues in Computing

...perception in the manufacturers and the users in the heat density reduction parameters, which need rationalization. Thermal management also needs to be included while designing devices and the issue is likely to become more complex over the years. Reduction of power is also related to power aware computing, which is designing software and hardware to ensure optimum management of power. Introduction The growth of information technology has spawned a vast industry based around computers and information science. The impetus to economies and employment provided by computing ignores the silent yet alarming environmental hazard posed by systems compressed in small spaces...

Simulation of Server Virtualisation

...Simulation of Server Virtualisation 1. Introduction and Overview of Server Virtualization 1.1 Introduction: Server virtualization is the method of splitting a server into different virtual servers. Virtualization broadly refers to the abstraction of computer resources. Each virtual server can run on its own as a different operating system and can be independently rebooted. The main intension of server virtualization is to increase the CPU utilization and congestion if any. One of the key factors involved in virtualization of server is to share the resources among servers. This can be done using partitioning of one server into many virtual servers. By doing this we can minimize physical servers i.e.,...

Legal issues in cloud computing

... Legal issues in cloud computing Testing A hardware purchase contract is an agreement that covers the purchase and supply of IT products. Since the hardware is individual equipment, it may be possible for the buyer of the IT product to test the equipment before accepting the contract. If the proper functioning of the equipment depends on its compatibility with other equipment, it may be appropriate for the customer to test the equipment’s functioning onsite after installation and reject it if it fails to perform as required. If this is the situation, the contract should include proper acceptance testing clauses. Such clauses usually require the customer or a supplier to test the equipment according to specified testing procedures... - and not...

History & impact of computing

...History and Impact of Computing History and Impactof Computing Introduction Computing refers to any activity, which is problem oriented that requires, benefits from or creates different algorithmic processes through the use of systems like computers. The computing process includes among other functions, designing, developing as well as establishment of software and hardware systems. It also features the art of structuring, processing and managing the different information, making scientific research using and on computers as well as coming up with computer systems that behave intelligently. The field of...

...VIRTUALIZATION Affiliation Virtualization is used to address and deal with the most challenging and pressing issues of any given IT organization. These challenges are associated with the infrastructure. IT departments tend to spend most of their funds in maintenance rather than using the money for business building and innovation. In his book, ‘Virtual and Mixed Reality in Telerobotics’, Costas discusses how this difficulty arises from the fact that today’s by86 servers are poorly designed. He says that they are made to run just one operating system and application at any given time. Due to this fact, even very small data centers are forced to deploy many servers though they can never operate at 100% efficiency (Costas, 2006... is then set...
