Introduction       A mouse may be a handled hardware data input data input device that controls a cursor during a GUI graphical user interface and may move and choose text, icons, files and folders on your computer.      For desktop computer, the mouse is placed on a flat surface e.g. ,mouse pad or desk ahead of your computer. The picture is an example of a personal computer mouse with two buttons and a wheel. the mouse was initially referred to as the X-y position Indicator for a Display System and was invented by Douglas Engelbart in 1963 while performing at Xerox PARC. But, thanks to Alto's lack of success, the primary widely used application of the mouse was with the Apple Lisa computer. Today, this pointing device is on virtually every computer.   Uses of Computer Mouse             Below may be a list of mouse functions to offer you a thought of all the items a mouse is capable of doing.  Move the mouse...

Introduction       A keyboard is one among the first input devices used with a computer. Similar to an electrical typewriter, a keyboard  consist of buttons wont to create letters, numbers, and symbols, and perform additional functions. The following section provide more in-depth information and answer to a number of the commonly asked  questions on the keyboard. Overview of Keyboard:-     The following image shows a 104-key Saitek keyboard with arrows pointing to every section, including the control keys, function keys, LED indicators, wrist pad, arrows key, and keypad.           The horizontal rows of character  keys have specific names. For example, when placing your hands on the keyboard, they ought to be positioned over the house row keys. The keys below the house row are called rock bottom row keys, and above the house row keys are the highest row keys.     Below may be a close-up image ...

 Introduction:-      CPU is the Central Processing Unit. Alternately mentioned as a processor, central processing unit, or microprocessor, the CPU is that the central processing unit of the pc. A computer CPU handles all instructions it receives from hardware and software and software running on the pc. The CPU is usually mentioned because the brain of the pc. However it's more appropriate to ask software because the brain and therefore the CPU as a really efficient calculator. A CPU is basically good with numbers, but if it wasn't for the software it wouldn't skills to try to to anything. Many new computer users may improperly call thir computer and sometime their monitor the CPU. When pertaining to your computer or monitor, it's proper to ask them as either the computer or monitor and not a CPU. The CPU is a chip inside the computer. The picture below is an example of what the highest and bottom of an Intel Pentium processor may look. The processor is placed and se...

Introduction of Computer        A computer is electronic machines. A computer is any machines which will be programed to hold out a group of algorithms and arithmetic and logical Unit. Computer is algorithms and arithmetic instruction. Of course, the computer we expect of today are such a lot quit that and I am talking beyond just being machines wont to pay games and watch videos of cats on the internet.   Parts of computer       Some parts of computer is given below:- Monitor Central Processing Unit ( CPU) Keyboard  Mouse Mother board  Graphics Processing Unit Random access memory  (RAM) HDD ( Hard Disc Drive) and SSD (Solid State Drive) It is a gaming system or a home PC. The some main components that structure a typical, present day computer include.          In term of construction each of those main components are attached to the motherboard then put into a protective case resembling the clean...

 A workstation may be a computer intended for individual use that's faster and more capable than a private computer. It's intended for business or professional use rather than home or recreational use. Workstations and applications designed for them employed by small engineering companies, architects, graphics designers, and any organization, department, or person who requires a faster microprocessor, and outsized amount of random access memory  (RAM), and special features like high-speed graphics adapters. Historically, the workstation developed technologically  about an equivalent time and for an equivalent audience because the UNIX OS, which is usually used Sun microsystems, Hewlett-Packard, DEC, and IBM. In IBM and other corporations, term workstation is usually wont to mean any individual pc location attached to a mainframe. In today's corporate environments, many workers have such workstations. They are simply personal computers attached to an area network  LAN...

 Introduction     A personal computer is that the common name for a kind of computer that's hottest in office and houses. The first PC called the IBM PC  was made by the corporate called IBM in 1981, although many computers were made before just like the commodore PET. Smartphones and computers for private use, but they are rarely called Personal computer.     Today most  PCs usually have a basic set of software called an operating system. The Operating system is liable for several tasks including providing a interface. The most popular Operating system  on PCs is windows, sold by Microsoft Corporation. PCs made by companies called apple Inc. can use a special system of software  called Mac Operating system that's called sold by apple Inc.     Many free operating system are available. They are called Linux Operating system. There are over 300 different Linux distribution. Each one has a different purpose. Ubuntu-Linux...

 Introduction  Main frames are a kind of computer that generally are known for his or her large size, amount of storage, processing power and high level of reliability. they're primarily employed by large organizations for mission-critical applications requiring high volumes of knowledge processing. Generally, there are a couple of characteristics of mainframes that are common among all mainframe vendors: Nearly all mainframes have the power to run multiple operating systems. Mainframes can add or hot swap capacity without disruption. Mainframes are designed to handle very high volume input and output and emphasize throughput computing. One mainframe can replace dozens or may be many smaller servers.     A mainframe, informally called a mainframe or big iron, may be a computer used primarily by large organizations for critical applications, bulk processing . A mainframe is larger and has more processing power than other classes of computers, like mini computers,...

 A mini computer is also known a small size of computer. It is a category of small computer that was introduced into the planet within the mid-1960. A mini computer may be a computer which has all the features of an out sized size computer, but its size is smaller than those, A mini computer lies between the mainframe and therefore the micro computer because its size smaller than the previous one and bigger than the latter inner. A mini computer is additionally called as a mid-range computer. Mini computer are mainly multi-users systems where quite one user can work simultaneously. Mini computer Example: IBM's AS/400e, Honaeywell200, TI-990.      Mini computer can support multi-user at a time otherwise  you can say that mini computers may be a multiprocessing system. Also the facility  of processing of mini computer isn't larger than the facilty of main frame and supercomputers. These minicomputers can do time-sharing, execution, and online processing. The ...

 A supercomputer may be a computer with a high level of performance as compared to a general purpose computer. Super computer play a crucial role within the field of computational science and are used for a good range of computationally intensive tasks in various fields, including quantum physics, meteorology, climate research, oil and gas exploration, molecular modeling and physical simulations. They need been essential within the field of cryptanalysis.          Since 2017, there are supercomputers which may perform over 1017 FLOPS. Since November 2017 all of the world's fastest 500 supercomputers run Linux-based operating system. Additionally research is being conducted within the ecu Union, within the us, Taiwan, Japan and china to create faster, more powerful and technologically superior exabytes supercomputer supercomputer ewer introduces worthen the 1960s, and for several decades the fastest ere made by Seymour Cray at control  Data Cu...
