Which of the following gates is also called as coincidence detector?

  1. AND

  2. XOR

  3. NAND

  4. NOR

  5. NOT


Correct Option: A
Explanation:

Coincidence circuits in computers operate when the input signals coincide precisely, i.e. overlap completely. In such devices, coincidence circuits perform the functions of AND logic elements.

Which of the following is also called as brain of a computer system?

  1. Memory

  2. ALU

  3. CPU

  4. Control unit

  5. Functional unit


Correct Option: C
Explanation:

Central Proccessing Unit (CPU) has all the components of the system. It computes all operations from basic to complex. It is also called the motherboard of the computer.

What is the full form of ALU?

  1. Array Logic Unit

  2. Arithmetic Logic Unit

  3. Application Logic Unit

  4. Application Layer User

  5. Antenna Loading Unit


Correct Option: B
Explanation:

An arithmetic logic unit (ALU) is a major component of the central processing unit of a computer system.

Which of the following is a volatile memory?

  1. RAM

  2. ROM

  3. EPROM

  4. EEPROM

  5. PROM


Correct Option: A
Explanation:

Volatile memory is a type of memory (storage) whose contents are erased when the system's power is turned off or interrupted. For example, RAM is a volatile memory.

Which of the following devices has a drawback of only storing the information but not erasing or modifing it?

  1. Floppy disk

  2. CDROM

  3. Hard disk

  4. Magnetic disk

  5. USB flash drive


Correct Option: B
Explanation:

The CD-ROM disks that you buy in the store are for reading information only.

Which of the following is responsible for converting an entire computer program into machine language?

  1. Compiler

  2. Interpreter

  3. Editor

  4. Emulator

  5. Debugger


Correct Option: A
Explanation:

A compiler takes your source programming code and converts it into an executable form that the computer can understand.

At the time of manufacturing, which of the following memories is programmed?

  1. EPROM

  2. RAM

  3. PROM

  4. EEPROM

  5. FLASH


Correct Option: C
Explanation:

PROM the data is programmed into them after manufacture. PROMs are used for smaller production where the program may have to be changed.

What was the name given to the first generation computer?
