  Q.2 which unit is used to measure the CPU's processing power ?

  A. GIPS

  B. LIPS

  C. MIPS

  D. Nanoseconds

Note: MIPS stands for million instructions per second and it is a unit used to measure the processing power of a CPU by indicating how many millions of instructions it can execute in one second.

Q.3 The CPU is an example of :

 A. Software 

 B. Peripheral device

 C. Hardware  

 D. input and output device

Q.4  A collection of wires that connects several devices or computer parts is called ?

A. Link wire 

B. bus

C. bidirectional wire

D. cable

Note: In computing, a bus is a collection of wire that serves as a communication channel or a pathway for transferring data between different components or devices in a computer system. 

Q.5 which of the following is used to connect microprocessor, memory, and other parts of computer ?

A. Data bus

B. Address bus

C. Path

D. Route

Note: the address bus is used to connect the microprocessor, memory, and other parts of  a computer. it carries the memory address from the processor to the memory, indicating where the data should be read from or written to.

Q.6 which of the following is equal to 4 bits ?

A. Byte

B. Nibble

C. Record

D. All of the above

Q.7 The collection of 8-bits is called as-

A. Byte

B. Nibble 

C. Word

D. Record

Q.8  Which of the following is correct about memory and storage ?

A. memory is temporary, storage is temporary

B. memory is temporary, storage is permanent

C. memory is permanent, storage is permanent

D. memory is slow, storage is fast 

Q.9 CISC stands for--

A. complex instruction set computer 

B. complete instruction sequential compilation

C. complex Instruction sequential compiler

D. none of the above

Q.10 What does EEPROM stands for --?

A. Electrically Erasable and Programmable Read Only Memory

B. Electronically Erasable and Programmable Read Only Memory

C. Electrically Enabled and Programmable Read- Only Memory

D. None of the Above

Note:  It is used to erase stored data using a high voltage electrical charge and re-programmed it. it is erased and reprogrammed electrically without using ultraviolet light

Q.11 __________ is a special types of memory that works like both RAM and ROM .

A. Register memory

B. Secondary Memory

C. Flash Memory

D. Cache Memory

Note: Flash memory is a special type of memory that works like both RAM and ROM flash memory is non-volatile , which mean it retains data even when the power is turned off, similar to ROM.

However, it is also rewritable like RAM, allowing data to be written and erased multiple times.

Q.12  which of the following is a type of memory and is similar to RAM ?

A. Cache

B. I Beam

C. ROM

D. Hypertext Link 

Q.13  In which memory the speed of the read and write Operations is same ?

A. PROM

B. ROM

C. BIOS

D. RAM

Q.14 What is the size of MAC (Media Access Control)  Address ?

A. 16-bits

B. 32-bits

C. 48-bits

D. 64 bits

Q15. which of the following is known as the step by step procedure to solve a problem ?

A. Graph

B. Table

C. Algorithm

D. None of the Above

Q.16. What does DRAM stand for ?

A. Dynamic Read Access Memory

B. Digital Random Access Memory

C. Dynamic Random Access Memory

D. Dynamic Read Allocation Memory

Q.17 which of the following is an essential data transfer technique ?

A. MMA

B. DMA

C. CAD

D. CAM

Note: DMA stand for direct memory Access. in the DMA data transfer scheme, data is transferred directly from an I/O devices  to RAM of from RAM to an I/O device.

Q.18 RISC stand for-

A. Remaining Instruction set of computer 

B. Remaining Intermediate Storage of Computer 

C. Reduced intermediate Storage of computer 

D. Reduced Instruction Set Computer

Q.19. In a program using subroutine call instruction, it is necessary________.

A. Reset the Microprocessor

B. clear the instruction register

C. clear the accumulator

D. Initialize Program counter

Q.20 what does the storage capacity of magnetic discs depend on ?

A. tracks per inch of surface

B. bits per inch of tracks

C. disk pack in disk surface

D. All options are correct

Q.21  where is the document temporarily stored during working on a document on PC ?

A. ROM

B. CPU

C. RAM

D. Flash memory  

Q.22 which of the following is a group of bits that tells the  computer to perform a particular operation?

A. Accumulator

B. Register

C. Instruction code

D. None of the above

Q.23 In which of the following form the computer stores its data in memory ?

A. Hexadecimal

B. Octal form

C. Binary form

D. Decimal form

Note: in a computer, the data is stored in binary form that is in the form of binary digit 0, and 1.0 mean 

OFF, and 1 means ON. A binary number is a base 2 number because it is either 0 or 1.

Q.24 What does MIMD stand for ?

Ans- Multiple Instruction Multiple Data
