definition of an operating system is:- “An Operating System is said to be the soul of any Pentium of computer or the type of computer.” Microsoft Windows is one of the known used operating systems now-a-days. Now a days windows covers 90% of operating system market stock. The basic reason behind the use of Microsoft Windows is; it is easy-to-use and comes equipped with all the services. Some of the types of operating systems are: • Open

when he, himself was in need of an operating system and turns out that other people need too so he started selling them his operating system. • Visicalc -It was the first electronic spreadsheet for financial planning. It recalculates the profits and expenses for the year so when you change the number, it pulls everything back. It started slow and eventually took off. People had the chance to invent their own scenarios and budget without taking so much of their time. Dan Bricklin, the Visicalc inventor

products arethe Microsoft Windows operating system, Microsoft Set of programs for office use of working well and getting a lot done software, Xbox, a line ofentertainment of games, music and video and Bing, a line of searchengines. In 1980, Microsoft formed a partnership with IBM that allowed them to bundle Microsoft's operating system with IBM computers, paying Microsofta royalty for every sale. In 1985, IBM requested that Microsoft write a newoperating system for their computers called OS/2; Microsoft

Security When asked the question which OS is more secure many people don’t really know the answer. All operating systems have their flaws such as the major security flaw that was found in the Mac OS X operating system. The security flaw causes many applications to skip a critical verification check when working with websites that utilize Transport Layer Security (TLS), and Secure Sockets Layer (SSL). This flaw would allow for a man in the middle attack while on a public or unsecured hotspot.

applications. The kernel is also known as the engine or core of an OS, the outermost part of an operating system that interacts with user commands. Some of the kernel’s tasks are resource allocation, process management, memory management, input/output device management, and security management. It basically mediates access to system resources. The kernel is the vital center of a computer operating system. The service layer acts as a source to resources for application programs such as folder manipulation

the various open source operating systems available. Pros: Operating System Name Pros Cons LINUX Cost : the most important advantage actually of using Linux as free operating system if we compare to another operating sustem like windows it's available for a hefty and sometimes recurring fee whereas a Linux distribution can be installed on any number of computers, without paying a single dime. Security : My motivation is that the Linux operating system is open source and if there

accomplished through the use of computer systems which use voice recognition, those computer systems which in turn communicate to

these two solutions are just extreme examples of how work may be allocated among a server and handheld client. Depending on circumstances, solutions in between these extremes may be useful and necessary. If one limits the discussion to a typical AR system which uses a single video source for both tracking and video see-through display, the processing pipeline is composed of the following main tasks: video acquisition, tracking, application computation, rendering, display. Offloading some of these tasks

that it gathers from files. Following diagrams explain the basic architecture of CPU: CPU performance is given by the fundamental law: Thus, CPU performance is dependent upon Instruction Count, CPI (Cycles per instruction) and Clock cycle time. And all three are affected by the instruction set architecture. Instruction Count CPI Clock Program x Compiler x x Instruction Set Architecture x x x Microarchitecture x x Physical Design x This underlines the importance of the

National Laboratory is asked to fix an error in the University of California, Berkeley campus computer usage accounts. After tracking the account in question he soon realizes it is not a student but an unauthorized user gaining root access to the campus systems by taking advantage of a loop hole. In the next 10 months that follow Stoll puts all of his effort in finding out who this intruder is. He borrows computers from co-workers and friends and attaches them to incoming phone lines- the route which computers

To enable better understand the key drivers for the launch of WIN8, we need to travel back in time to year 2006-2007, when the WINDOWS long awaited VISTA operating system was launched. The product initially was received well, with around 55million licenses sold world-wide in the year 2007, which enabled the company to show strong top line results in line with market expectations for the fiscal year 2007. But the replacement and projected new volumes that was expected post 2007 did not materialize

details of the specified gaming devices. 1. COMPUTERS : Computers are electronic devices that began with the introduction of microprocessors in the 20th century. They were systems used for many purposes at the early time. Calculation, Billing, Messaging and so on were done using computers. Computers were classified into 3 specific groups

Apple is very good in integration of its products, Over the period of time Apple has kept the strategy of vertical integration so that products of apple are compatible to each other irrespective of you are using one product or other. For example all the products be it a PC, I phone or ipad are comparable, compatible in many ways of operating system, Features, Hardware, other software applications hence the user feels very comfortable using apple products. Apple does very good in Research and development

This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case

One Amazing Thing. Chitra Banerjee Divakaruni. USA: Hyperion, 2009. 209pp. Under the rubric of Commonwealth Literature, there is always a bewildering array of overlapping and intersecting experiences between ‘home’ and ‘abroad’. The ‘rootlessness’ which is central to an immigrant consciousness also connotes an underlying phenomenon of ‘give-and-take identity politics’ of a pre-defined identity along with the coterie of religious, cultural, racial, social values and norms thus become a site of hope

He started out by making a microprocessor chip in 1979, and called it the “8086 Chip”(Dickson 35). Then he made MS-DOS the standard operating system for all of Microsoft. To add on to that in 1985, Bill launched Windows 1.0 ,which for the first time, allowed you to click something on the screen and then the computer will open it (Demuth 59). Gates then noticed that his program, Microsoft was lacking an internet browser. So in 1995, he launched

Computers. Phones. Cars. Televisions. Inventions that could be viewed positively, but at the same time negatively. As the world grows and develops each and every day, many creations, both beneficial and harmful, are generated. One creation that stands out in a pool of many is fracking. Fracking is a method that involves drilling into the Earth using water at high pressure in order to extract natural gases. Water and sand are inserted into the shale formations at high pressures in order to make cracks

The air hockey table game was invented in 1969 by a group of Brunswick engineers of Brunswick Billiards. You will realize that it was initially drafted for commercial release but was set aside for some time. However, after several years, the engineers designed the first air hockey game. The game was originally played on a table. One has to utilize a disk and squared mallets. Currently, the game is normally played using round mallets. The table normally provides a smooth surface that generates zero

Memory Management. Memory management is the process of controlling and coordinating computer memory, Assigning portions called blocks to various running programs to optimize. This is the functionality of an operating system which manages primary memory. It keeps track of each and every memory location. It also does update whenever some memory gets free or unallocated. Memory management has two schemes. 1. Single user case - mono programming 2. Multi user case - multi programming Memory management
