What is the main function of the Control Unit in a computer?

• To execute instructions

• To transfer data between input and output devices

• To perform arithmetic operations

• To store data

Which of the following is a type of architecture used in the computers nowadays?

• Microarchitecture

  Von-Neumann Architecture

• System Design

To reduce the memory access time we generally make use of ______

• SDRAM’s

• Heaps

• Cache’s

• Higher capacity RAM’s

In a CPU, what role does the Program Counter (PC) play?I

• It holds the address of the next instruction to be executed

• It stores data

• It performs arithmetic operations

• It executes instructions

  
  

A CPU is not executing instructions in the correct sequence. What could be the problem?

• Cache failure

• ALU failure

• Faulty Program Counter

• Memory overflow

A CPU is taking too long to complete arithmetic operations. What is a likely cause?

• Clock speed too fast

• Instruction pipeline failure

• Faulty control unit

• ALU malfunction

What is the primary purpose of cache memory in a computer system?

• To increase storage capacity

• To execute instructions

• To store large amounts of data

• To speed up access to frequently used data

What is the difference between SRAM and DRAM in the memory hierarchy?

• DRAM is faster and used for cache

• Both are equally fast

• SRAM is faster and used for cache

• SRAM is used for main memory

Which of the following is an example of secondary storage?

• Registers

• Cache

• RAM

• Hard disk

Given a CPU with L1, L2, and L3 cache, which cache will be accessed first when data is needed?

• L1

• L3

• None of the above

• L2
