Hardware

Hardware is divided into four parts.

C.P.UInputOutputStorage

C.P.UCPU is divided into three parts.

CU (Control Unit)

ALU (Arithmetical and Logical Unit)

MU (Memory Unit)

Input DeviceKEY BOARD

MOUSE

Output Device

An output device is an electro-mechanical device that accepts data from computer and translates into a form that can be understood by outside world.

Display Device

Printers

Primary Storage Device

RAM:- RANDAM ACCESS MEMORY

ROM:- READ ONLY MEMORY

RAMRandom Access Memory is a Primary storage

device which store the data temporary. RAM is a read and write data easily.

Capacity of RAM:- 512 MB (Mega Bytes) 1 GB (Giga Bytes) etc.

ROMROM is stand for Read Only Memory.

It only read the data for the configuration of computer.

Secondary StorageHDD (Hard Disk Drive)

FDD (Floppy Disk Drive)

CD-ROM (Compact Disk-Rom)

Hard Disk DriveUnlike Floppy disk, hard disks are made up of

rigid metal. The sizes for the disk platters range between 1 to 14 inches in diameters. It can be categorised as disk packs or Winchester disks.

Hard Disk Drive where store the data permanently on hard disk. It is fixed disk drive.

Invent in the year 1950.

Its drive name is C:\.

Floppy Disk DriveFloppy Disk drive which store the data

permanently but FDD are moveable. There are two sizes commonly used, with diameters of 51/4 and 31/2 inches.

Its drive name is A:\.

The capacity of FDD is 1.44MB.

FDD invent in the year 1970

Compact Disk - ROMCD-ROM drive is a secondary storage device

but not write the data because this drive is only for readable. It is fast and inexpensive mass replication. It can be read-only and cannot be updated.

The drive name is G:\

It Invent in the year 1970.

There are two types of software:

Systems software: the operating system.

Applications software: the programs we use.

System Software

System software is a collection of programmed design to operate, control and the extend the processing capability of computer.

Language Translator. A software that convert source code into the machine code & vice-versa.

Language TranslatorInterpreter:- An Interpreter can translate

program Source code to Object code line by line. It take very long time to execute any program.

Compiler:- A complier also convert the program to object code to Source code once at a time. It is very faster than the interpreter.

Application SoftwareApplication software is the term use to

describe software program the perform some specified task for the user.

Standard Product:- D-Base, FoxPro, C, C++ etc.

Normal Product:- Accounting Package Tally.

Standard ProductC was design by Denis

Ritchie

#include <stdio.h>#include<conio.h>Void main(){printf “My Name is Khan”;getch();}

Output

“My Name is Khan”

Forton - Early computer were almost exclusively used by scientist. The first high level language (Formula Translation) was developed about 1956 by John Backus at IBM.

COBOL – COBOL (common business oriented language), The first language included for commercial application “was developed by a committee of computer manufacturers and user under the leadership Grace Hopper.
