What Is a Computer ?
A computer is a programmable electronic device that process data according to instruction given by
a computer program. Computers operate on a set of instruction and can execute a pre-recorded list of these instructions. The word ” computer ” comes from the Latin word ” compare ” which means to count.
A computer basically has two parts, one is Hardware and the other is Software . All the comporents
in a computer that consist of circuits, transistors, hard disk, wires are called Hardware whereas the
program and data are called Software.
1. Memory : Memory empowers a computer to store , at slightest briefly, information and programs.
2. Processor : It executes enlightening for program and equipment.
3. Input device : As a rule console and mouse, the input gadget is the conduit through which
information and informational enter a computer.
4. Output Device : An yield gadget may be a show screen, printer, or other gadget that lets you
see what the computer was finished.
5. Motherboard : It is the portion that interfaces all other parts of components of a computer.
6. Storage Device : It for all time stores the information, e.g. , difficult drive.
How many kinds of Computer and which this ?
Personal Computer : A PC could be a little , single-user computer based on a chip. In addition to
the chip , a individual computer includes a console for entering information , a screen for showing data , and a capacity gadget for sparing information.
Mini Computer : Mini-computers are moreover known as ” Midrange Computers”. They are not planned for a single. They are multi-user computers outlined to back numerous clients at the same time. So, they are by and large utilized by little businesses and firms. Person divisions of a company utilize these computers for particular purposes. For illustration , the affirmation office of a college can utilize a Mini-computer for observing the confirmation prepare.
Mainframe Computer : It is additionally a multi-user computer competent of supporting thousands of clients at the same time. They are utilized by huge firms and government organizations to run their trade operation as they can store and prepare huge sums of information. For illustration, Banks, colleges and protection companies utilize centralized computer computers to store the information of their clients , understudies and policyholders individually.
Work Stations : It may be a single-user computer. In spite of the fact that it is like a individual computer, it encompasses a more capable chip and a higher-quality screen than a microcomputer. Work stations are by and large utilized for specialized applications such as desktop distributing , program advancement and designing plans.
Super Computer : Super-computers are the quickest and most costly computers among all sorts of computers. They have gigantic capacity capacities and computing speeds and hence can perform millions of informational per moment. The super-computers are task-specific and in this way utilized for specialized applications such as large-scale numerical issues in logical and designing disciplines counting applications in gadgets, petroleum building , climate determining, medication , space inquire about and more. For illustration , NASA employments super computers for propelling space satellites and checking and controlling them for space investigation.
