2.  It draw the picture on the screen
 We see the soft wares with the help of
monitor
2

3. It is the pointing device
It helps us to open or close the program
3

4. With the help of it we give data to the computer. It contains button
which helps us to write or study program

5.  Chassis
 Motherboard
 Power Supply
 Hard Disk Drive
 Floppy Drive
 CD/DVD Drive
 RAM and ROM
 Microprocessor
 Expansion Cards
 Ports and Connectors
 Sockets and Slots
 Chipset
5

6.  It is formed by metallic element.
 it is also called computer case
 It houses mother board, power supplier,
HDD, CD/DVD drive and other internal parts.
 Chases are of many types e.g: desktop type
or tower type etc
 They also gives some outside ports for
connecting devices.

8.  It is the back bone of Computer
 It is present on the ground of the chase
 It consists of RAM, ROM, MP, Slots,
Connectors, etc
 Without it computer will not run.

10.  It abbreviate as PSU.
 It provides the power to the motherboard.
 On it’s backside we connect power to it.
 Many types of connecters are connected
through it.
 Red connector are used to on and off the
computer.
 Many cables are going through it to supply
power to motherboard.
 Like ATX, MOLEX ….
10

11.  Abbreviate as HD or HDD
 It was first introduced in 1956
 It stores data permanently
 Main storage device
 ATA, SCGI and SATA cables are used for it.
11

12.  First manufactured in 1971
 It is remove able diskettes
 It is just for storing something of users
12

13.  Compact disc read only memory.
 It only reads memory not write.
 It is also known as optical drive.
 It contains software or audio type data.
 It’s version are changed up to 72
13

14. 14

15.  Random access memory
 Some times these are called eyes of the
computer
 It is primary and main memory
 It stores data temporary it is volatile memory.
 There are two types of RAM
 1-SRAM 2-DRAM
15

16.  Stands for Dynamic random access memory
 It is made of capacitors
 If it is charged it holds 1 other wise 0
 One transistor is also used to read the data
 It has habit of losing data so it will be
refreshed
 Cheaper than SRAM also smaller and slower
than SRAM
 Due to refreshing option it is so called
dynamic
 Primary memory is made up of D-RAM
16

17. 17

18.  1-SRAM: static random access memory
 Single flip flop used to stores one bit of data
 Single flip flop is made up of 4 to 6
transistors It doesn't losses data after every 1
mille second
 It is the reason so it no need refreshed
 It takes more space than D-RAM also it is
faster than D-RAM
 It is larger than D-RAM
 It is more expensive than D-RAM
 Cache memory is also made up of S-RAM
18

19. 19

20.  Stands for read only memory
 It stores data permanently
 It stores BIOS it is non volatile memory also it
is primary memory
 It works even the computer is off
 The function of BIOS is to BOOT means the
start of the function

22. ◦ PROM
◦ EPROM
◦ EEPROM
◦ PROM
◦ Programmable read only memory
◦ Also called one time programmable(OTP)
◦ It can store or read memory only one time
◦ Once program is written it cannot be changed
◦ It is programmed by special programmer called
PROM burner

23. 23

24.  EPROM stands for Erasable Programmable
Read Only Memory.
 it can be programmed again and again.
 When we reprogram EPROM, it must be first
erased(clean)
 It is erased by passing UV through it
 In order to reprogram, the EPROM must be
remove from the computer b/c we have to
clean it
24

25.  EEPROM stands for Electronically Erasable
Programmable Read Only Memory.
 It can be erased and reprogrammed again
and again
 It will be erased in the computer.
 We will not remove it from computer
25

26.  It is also called brain of the computer
 It was first manufactured by Intel company in
1970
 It process data into information with the help
of some hardware and soft wares
26

27. 27

28.  PGA : pin grind array
 Pins are on the top of the ground
 LGA: land grind array
 It is the surface type packing
28

29.  A port serves as an interface between the
computer and other computers or peripheral
devices.
 There are some ports and connector which
used to give power to the mother board and
also to connect some devices with themselves
29

30. Slots are used to connect some devices with motherboard. eg
graphic card etc
