1. Ans. B. 

CDROM is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for Compact Disc Read-Only Memory. Computers can read CDROMs, but cannot write to CDROMs which are not writable or erasable. Keep in mind that drives such as a CDROM, DVD, Floppy diskette drive, and a USB Flash drive may be capable of sending information to a computer, but they are not input devices. They are considered storage devices. Hence CD-Rom is an output device.

2. Ans. D. 

An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by a computer that converts the electronically generated information into human-readable form. Examples of the output device include monitors, projectors, speakers, headphones and printers.

3. Ans. B. 

The difference between a PROM and a ROM (read-only memory) is that a PROM is manufactured as blank memory, whereas a ROM is programmed during the manufacturing process. To write data onto a PROM chip, you need a special device called a PROM programmer or PROM burner.

4. Ans. B. 

Complementary metal-oxide semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM and other digital logic circuits.

5. Ans. A. 


  • Random-access memory (RAM) is a form of computer data storage. A random-access memory device allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory.
  • In contrast, with other direct-access data, storage media such as hard disks, CD-RWs, DVD-RWs and the older drum memory, the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement delays.


6. Ans. D. 

Magnetic Ink Character Recognition Code (MICR Code) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents.

7. Ans. C. 

The hardware device commonly referred to as the “brain” of the computer is the CPU.

10. Ans. B. 

The shift key is a modifier key on a keyboard, used to type capital letters and other alternate upper characters. There are typically two shift keys, on the left and right sides of the row below the home row. The shift key’s name originated from the typewriter, where one had to press and hold the button to shift up the case stamp to change to capital letters

11. Ans. E. 

A supercomputer is a computer that performs at or near the currently highest operational rate for computers.
Traditionally, supercomputers have been used for scientific and engineering applications that must handle very large databases or do a great amount of computation (or both).

12. Ans. A. 

byte is a unit of digital information that most commonly consists of eight bits.
Each 1 or 0 in a binary number is called a bit.
From there, a group of 4 bits is called a nibble, and 8bits makes a byte. Bytes are a pretty common buzzword when working in binary.
Note:-The byte was the number of bits used to encode a single character of text in a computer and it is the smallest addressable unit of memory in many computer architectures.

13. Ans. E. 

ASCII, abbreviated from American Standard Code for Information Interchange, is a character-encoding scheme. ASCII codes represent text in computers, communications equipment and other devices that use text.

14. Ans. C. 

WAP(Wireless Application Protocol) is a technical standard for accessing information over a mobile wireless network.

15. Ans. A. 

The scrambling of code is known as encryption. It is the process of converting information or data into a code, especially to prevent unauthorized access.

16. Ans. C. 

A filename (also written as two words, file name) is a name used to uniquely identify a computer file stored in a file system.
