(a) The computer is a machine and it has to do similar functions like our brain. Therefore, artificial memory is an important part of the computer.

(b) Erasable Programmable Read Only Memory provides with a facility to erase the program as well as to write a fresh program.

(c) 0 and 1 are two numbers used in binary system.

(e) Letters and numbers become a series of long or short sounds, known as dots and dashes.

(f) A computer sends an electrical pulse though electronic circuits to process the data.

1. What are the two things which are used by a computer to process the data ?

3. Describe the data coding and functioning .

4. What do you understand by computer logic ?

5. Write a short note on computer memory .

2. Explain how the computer works .

1. PROM

2. EEPROM

3. Bits and Bytes

4. Semiconductor memory

16 Bits= _____ Byte

1024 Bytes = _____ KB (Kilo Byte)

_____ KB = 2 MB (Mega Byte)

_____ MB= 3 GB(Giga Byte)

2048 GB = _____ TB(Terra Byte)

_____ TB = 4 PB(Peta Byte)

1024 PB = _____ EB(Exa Byte)

1024 EB = ZB(Zetta Byte)

3072 ZB = YB (Yotta Byte)

_____ YB = 1 (Bronto Byte)

4096 Brontobyte = _____ (Geop Byte)

(a) The collection and preservation of records and their recall when needed are the _____________ of memory.(functions/computer).

(b) The functions of a computer are _____________ to the mental jobs done by human beings.(similar/ different)

(c) Sequential access memory is to read and _____________ sequentially.(write/learn)

(d) Read Only _____________ is permanent memory.(Memory/ RAM)

(e) ___________EPROM is the same as the EPROM but it only differs in the process of erasing. (Electrically/ Auxiliary)

(f) A computer takes in ______ facts.(raw/ripe)
