Basic Computer and Fundementals
What is Computer?
It is an Electronic DeviceIt knows 0's and 1's.It is known as Binary language.
Every Computer should runs on Operating System.
Operating System
- Interface between Hardware and Software.
- We can touch physically but we cannot intreact easily.
Major Types of Hardware Devices
I)Input Device ==> Example) Keyboard
II)Output Device ==> Example)Monitor - Software
- It is a set of Programs.
Major Types of SoftwaresI)System Softwares
Example)Operating System
II)Application Software
Example)Word,Tally - ALU
- It stands for Arithmetical Logical Unit.
It will process of our inputs and it will send it to the output unit.
To Process the inputs we use Processor(Intel,Pentium) - It is one kind of storage in computer.
Major types of Memory
1)Primary Memory
Example) RAM(Random Access Memory),ROM(Read Only Memory)
2)Secondary Memory ==>
Example) Hard Disk,SD Card,Pendrive 1)8 bits 1 Byte 2)1024 B 1 KiloByte 3)1024 KB 1 MegaByte 4)1024 MB 1 GigaByte 5)1024 GB 1 TeraByte
