Definition of Computer

PC is an advanced programmable electronic machine which recognizes data from the customer and assume that data as showed by predefined heading and give the ached for result. "PC" is gotten from the Latin word "Computer" which means to determine.

Vital Terms used as a piece of Computer

1.   Input: data is the data and heading which is nourishment to the PC.

2.  Input Devices: Input contraptions are those devices which are used to give data and course to the PC. For example: Mouse, console, Scanner et cetera.

3. Output: Output is a result, which is taken from rule memory (RAM).

4. Output Devices: Output contraptions are those devices which are used to show the result. For example: Monitor, Printer, Speaker et cetera.

5. Software: Software is an aggregation of framework furthermore set of information, which are plan and made by programming engineer by using programming vernacular to perform of specific undertaking furthermore wide task. For example: Ms. Office group, PageMaker, Tally, Corel Draw et cetera.

6.   Hardware: Hardware is the physical parts of PC which can be touched and seen. Case in point: Microprocessor, CPU fan, Monitor, RAM et cetera.

7.    Data: Data is a get-together of unrefined materials.

8.   Information: Information is a get-together of data and also took care of data which is significance full.

9.   Program: Program is a course of action of bearing which are use to play out some specific errand.

10.  CPU: It stays for Central Processing Unit. It is a hart and also cerebrum of the PC. It has three crucial parts. They are:

A.  ALU: it stays for Arithmetical and Logical unit which is responsible for playing out all key numerical and intelligible operations like, extension, subtraction, division and duplications.

B.   CU: it stays for Central Unit which is responsible for bringing the rule from rule memory (RAM).

C.   MU: It stays for Memory Unit it is generally called Resister Array which is responsible for securing widely appealing result between time since it is a temporary zone in the CPU.

11.  Microprocessor: It is a processor of CPU which is natural single chip. It is made by Silicon metal. For example: 80286, 80386, Dual Core, i3, i5 et cetera.

12.  Memory: Memory is a chip, contraption, space where we can store data and course.

13.  RAM:- It stands the Random Access Memory it is a key memory which is used to store data brief and it is in like manner used to fabricate the rate of PC and it is also knows as insecure memory since it loses its substance when power supply is off.

14. ROM:- it stays for Read Only Memory it is generally called non-eccentric memory since it doesn't loses its substance when power supply is off. It is for the most part used to store pre portrayed bearings used to execute working system known as firmware.

15.    Firmware:- Firmware are the predefined heading set away on RAM while creation of RAM, use execute working system.
