Introduction of Computer.

                           Class-01 

Computer-

                      Computer is an electronic device. It was performs to control the instructions and store data for future use. And Computer generally use for all type of arithmetic work. Computer the word come from Latin word compute tha means to calculate so Computer is call calculating device also. Computer have basically two type such as-:
* Digital Computer
* Analog Computer

Digital Computer- is most commonly used type of computer. A computer that performs calculations and logical operations. And it was converte decimal number system to the binary number system. It is used for processing data represented by discrete, localized physical signals, as the presence or absence of electric current.

Analog Computer-An analog computer is a computer which is used to process analog data. Analog computers store data in a continuous form of physical quantities and perform calculations with the help of measures.

Function of Computer

     Computer function have five types such as-:
* Take data as input.
* Store data instructions in its memory and 
   use data them when required.
* Process the data convert it into useful 
   Information.
*Generate the out put.
* Control total all over four steps.

Data-                        Processing-               Information

Computer Components

       Computer components have two type such as-:
*Hardware
*Software

*Hardware- Hardware means the physical parts of computer system. Such as-: Monitor mouse, keyboard, camera,data storage,hard disk, graphic card,sound card memory, mother board, and chips etc.

*Software- Software is a set of program and it was designed to perform well-defind function. 

Some Software example are-: Windows, Linux, Dos,Vista, Microsoft office, Photoshop etc.
Software are devided by two type such as-:
*System Software
*Application Software

System Software-: System Software is a collection of program. And it was designed to operate control the processing capabilities of computer. It was all ready given to System manufacturer's. Some system software are such as-:

*Close to the system
*Fast in speed
*Difficult to Design
*Difficult to understand
*Less interactive
*Smaller in size
*Difficult to manipulate etc.

Application Software-: in this application software are designed to satisfy of a particular environment.application software may consist of a single program. Some application software are such as-:

*Pay roll
*Inventory management software
*Income tax software
*Microsoft office Software
*Photoshop software
*Tally Software
*Sassy to design software etc.
