COMPUTER HARDWARE NETWORKING
2
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.

Objectives

• Role of hardware.
• Describe hardware components, and explain each
  component.
• Features of networking

Hardware Components of Computer -

1. C.P.U.
2. CARDS
3. MOTHER BOARD
4. RAM

5
Central Processing Unit (CPU)

• Component of CPU

• Arithmetic Logic Unit- ALU ALU performs
  arithmetic logical operations.
• Control Unit- cu CU extracts instructions
  from memory and decodes and
  executes them, calling the ALU when necessary.

6
CARDS

• Graphic Card
• Video Card
• Sound Card

MOTHER BOARD
8
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.

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

11
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.

12
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).

13
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.
