- 2. It drawthe picture on the screen We see the soft wares with the help of monitor 2
- 3. It is thepointing device It helps us to open or close the program 3
- 4. With the helpof it we give data to the computer. It contains button which helps us to write or study program 4
- 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 isformed 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. 6

- 8. It isthe 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. 8

- 10. It abbreviateas 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 asHD 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 manufacturedin 1971 It is remove able diskettes It is just for storing something of users 12
- 13. Compact discread 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

- 15. Random accessmemory 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 forDynamic 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.
- 18. 1-SRAM: staticrandom 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

- 20. Stands forread 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 20

- 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 22

- 24. EPROM standsfor 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 standsfor 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 isalso 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

- 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 portserves 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 usedto connect some devices with motherboard. eg graphic card etc 30
