NETWORKING
 Presented By :-

3. Elements of Computer System:-
 A computer system consists of two major elements:
Hardware and Software.
 Hardware is the collection of all the parts you can
physically touch.
 Software, on the other hand, is not something you can
touch. Software is a set of instructions for a computer to
perform specific operations.

4. Objectives
 Role of hardware.
 Describe hardware components, and explain each component.
 Features of networking

5. Hardware Components of Computer :-
1. C.P.U.
2. CARDS
3. MOTHER BOARD
4. RAM

6. CENTRAL PROCESSING UNIT (CPU)
1. Arithmetic Logic Unit- [ALU] = ALU performs arithmetic logical operations.
2. Control Unit- [cu] = CU extracts instructions from memory and decodes and
executes them, calling the ALU when necessary.
Component of CPU :

7. CARDS
 Graphic Card
 Video Card
 Sound Card

8. MOTHER BOARD

9. RAM
 RAM is a semiconductor that stores charges with
transistors and capacitors.
 Dynamic RAM (DRAM) -
 Most popular type of electronic memory in the PC
world.
 Static RAM (SRAM)- very expensive does not have to
be refreshed.

11. PAN
 A personal area network (PAN) is the interconnection of
information technology devices within the range of an
individual person, typically within a range of 10 meters

12. LAN
 A local area network (LAN) is a computer network that
interconnects computers within a limited area such as a
home, school, computer laboratory, or office building, using
network media.

13. MAN
 A metropolitan area network (MAN) is a network that
interconnects users with computer resources in a geographic
area or region larger than that covered by even a large local
area network (LAN) but smaller than the area covered by a
wide area network (WAN).

14. WAN
 A wide area network (WAN) is a network that covers a broad
area (i.e., any telecommunications network that links across
metropolitan, regional, national or international boundaries)
using leased telecommunication lines.
