What is Computer : Computer is an electronic device that is designed to KAMC work with Information. The term computer is derived from the Latin term ‘computare’, this means to calculate or programmable machine. Computer can not do anything without a Program. It represents the decimal numbers through a string of binary digits. The Word ‘Computer’ usually refers to the Center Processor Unit plus Internal memory. Charles Babbage is called the “Grand Father” of the computer. The First mechanical computer designed by Charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards. The computer is an electronic device that takes input from the user and processes these data under the control of a set of instructions (called program) and gives the result (output) and saves future use. It can process both numerical and non-numerical (arithmetic and logical) calculations. The basic components of a modern digital computer are: Input Device, Output Device, Central Processor Unit (CPU), mass storage device and memory.
IBM's first PC was introduced on 12 August 1981 setting what became a mass market standard for PC architecture. In 1982 "The Computer" was named Machine of the Year by Time magazine. Somewhat larger and more expensive systems were aimed at office and small business use. These often featured 80-column text displays but might not have had graphics or sound capabilities. These microprocessor-based systems were still less costly than time-shared mainframes or minicomputers. Workstations were characterized by high-performance processors and graphics displays, with large-capacity local disk storage, networking capability, and running under a multitasking operating system. Eventually, due to the influence of the IBM PC on the personal computer market, personal computers and home computers lost any technical distinction. Business computers acquired color graphics capability and sound, and home computers and game systems users used the same processors and operating systems as office workers. Mass-market computers had graphics capabilities and memory comparable to dedicated workstations of a few years before.
When researching computer companies before a computer purchase, consumers can find out if they offer recycling services. Most major computer manufacturers offer some form of recycling. At the user's request they may mail in their old computers, or arrange for pickup from the manufacturer. Hewlett-Packard also offers free recycling, but only one of its "national" recycling programs is available nationally, rather than in one or two specific states. It encourages the shared approach of collection points for consumers and recyclers to meet. Manufacturers often offer a free replacement service when purchasing a new PC. For example, Dell Computers and Apple Inc. may take back old products when one buys a new one. Both refurbish and resell their own computers with a one-year warranty. Many companies purchase and recycle all brands of working and broken laptops and notebook computers from individuals and corporations. Building a market for recycling of desktop computers has proven more difficult than exchange programs for laptops, smartphones and other smaller electronics.
Computers can use many bits together to represent instructions and the data that these instructions use. A list of instructions is called a program and is stored on the computer's hard disk. Computers work through the program by using a central processing unit, and they use fast memory called RAM (also known as Random Access Memory) as a space to store the instructions and data while they are doing this. When the computer wants to store the results of the program for later, it uses the hard disk because things stored on a hard disk can still be remembered after the computer is turned off. An operating system tells the computer how to understand what jobs it has to do, how to do these jobs, and how to tell people the results. Millions of computers may be using the same operating system, while each computer can have its own application programs to do what its user needs.

You possibly can move your mouse around minus the constraint of wire. That is a fantastic way to perform your task. A computer perform with out a mouse but it surely will be quite hard make use of. Monitor: The computer monitor is the most important area of the computer besides the hard disk. The computer monitor means that you can see images and what is on your computer. You’ll find average size monitors, wide screened monitors and flat screened monitors. You can even find HD monitors that deliver a even clearer pictures. How big is the computer monitor depends upon what size you require for which you’re doing with the computer. With larger screens you will possess the chance to watch a number of movies in television size. Web Camera: a website camera is usually green on your computer helping you to take images and videos and save them straight to your laptop.
