Explanation

1.CD-ROM

There are no objects with the name as in other options. CD-ROM is a non-volatile optical data storage medium using the same physical format as audio compact disk, readable by a computer with a CD-ROM drive.

2. UNIVAC 

There are no computers with the name as in other options. UNIVAC was the first general purpose electronic digital computer designed for commercial use, produced by Universal Accounting Company of John Mauchly and J.P.Eckert in 1951.

3. MSI 

After the invention of IC chips the development of computers plunged into next phase. Small Scale Integration and Medium Scale Integration (SSI and MSI) were used in third generation of computers and Large Scale Integration and Very Large Scale Integration (LSI and VLSI) are being used in fourth generation of computers. 

4. The capacity of 3.5 inch floppy disk is

Microfloppy disks (3.5 inch) if it is high density (MF2HD) can store 1.44 MB and if it is low density (MF2DD), it can store 720 KB. Mini Floppy disks (5.25 inch) if it is high density (MD2HD) can store 1.2 MB and low density (MD2DD) stores 360 KB of data.

5. WAN 

There are three different classes of computer network namely, Local Area Network (LAN) that covers a small geographical area such as a room, a building or a compound; Metropolitan Area Network (MAN) that has a citywide coverage; and Wide Area Network (WAN) that covers the whole globe or beyond the globe.

6. ALU 

ALU is a unit in Central Processing Unit in a computer system that is responsible for arithmetic calculations and logical operations. Apart from ALU, the CPU contains MU (Memory Unit) and CU (Control Unit).

7. MICR

MICR (Magnetic Ink Character Reader) is kind of scanner that can scan and identify the writing of magnetic ink. This device is used in banks to verify signatures in Checks.

8.MU

It is the location to store the information. It can be divided into 2 parts. 

They are 

A.Primary memory unit 

B. secondary memory unit

9. ASCII 

ASCII is a code which converts characters – letters, digits, punctuations and control characters such as Alt, Tab etc – into numeral form. ASCII code is used to represent data internally in micro-computers. ASCII codes are 7 bits and can represent 0 to 127 and extended ASCII are 8 bits that represents 0 to 255.

10. EEPROM 

There are three types of ROM namely, PROM, EPROM and EEPROM. PROM can’t be reprogrammed, EPROM can be erased by exposing it in high intensity ultraviolet light and EEPROM can be erased and reprogrammed electrically. It is not needed to be removed from the computer to be modified.
