The document discusses the various hardware components that make up a computer system. It describes the motherboard as the main circuit board that connects all the components together, including the CPU, RAM, graphics card, hard disk, power supply, and other parts. Storage units and their standard sizes like bytes, kilobytes, megabytes, and terabytes are defined. Common processor brands and the recommended RAM and uses for different levels of computer systems are outlined. Peripheral devices like DVD drives, floppy disks, memory cards, and more are also listed.

3. Central Processing Unit (CPU)

4. Mother Board
TO INTERCONNECT EACH AND EVERY HARDWARE OF COMPUTER
A computer motherboard is nothing but the circuit board or
the circuit which controls the entire functioning of the
computer. All the components that form your computer are
connected to the computer motherboard.

8. Hard Disk
INTERNAL PERMANENT STORAGE DEVICE OR
SECONDARY MEMORY (FOR STORING DATA)
E.g.:- 250 GB; 320 GB; 500 GB

9. Random Access Memory (RAM)
TO GIVE ACCESS TO DATA FOR ON GOING FUNTION
OR PROCESS ON COMPUTER
EG:- 1GB; 2GB; 3GB; 4GB; 5GB; 6GB; 7GB; 8GB
RAM (Random Access Memory) is system's short-term
memory or Primary memory. RAM is used by the system to
store data that is processed by a computer's CPU. Higher
more RAM you have, the more things your computer can
do at the same time, and the faster your computer
performs certain tasks.

10. PROCESSOR
•ACT AS PROCESSING DEVICE OF COMPUTER
e.g.:- INTEL CORE 7i ; INTEL CORE 3i ; INTEL
CORE 2 dual ; INTEL DUAL CORE ; ATOM;
AMD
The processor is the central focus of the computer. It has three main tasks:
1. Receiving input (including memory access)
2. Giving output (including memory access)
3. And performing mathematical and logical calculations

11. Graphics Card
For better picture quality

12. TV Tuner Card
Convert analog T.V signal to Digital Signal
