Computer Architecture | MCQs

Explanation

The Control Unit (CU) directs the flow of data and instructions within the CPU.

It manages communication between the memory, ALU, and input/output devices.

Explanation

ROM (Read-Only Memory) contains the firmware or BIOS needed to boot the computer.

It is non-volatile, meaning it retains data even when the power is off.

Explanation

The Arithmetic Logic Unit (ALU) is the part of the CPU responsible for performing arithmetic and logical operations.

It handles calculations like addition, subtraction, and comparisons.

Explanation

The fifth generation of computers focuses on Artificial Intelligence (AI).

These computers use advanced technologies such as natural language processing, biochips, and expert systems.

Explanation

Explanation

The Control Unit (CU) directs and coordinates most operations of the computer by managing the flow of data and instructions.

It tells the ALU, memory, and I/O devices how to respond to instructions.

Explanation

The CPU (Central Processing Unit) executes instructions and performs calculations.

This making it the primary component responsible for processing data in a computer.

Explanation

OS computer Abbreviation usually means Operating System.

An Operating system is an integrated set of programs that are used to manage the various resources and overall operations of a computer system.

Explanation

A buffer is a temporary storage area that holds data while it is being transferred between two devices or processed by the CPU.

It helps manage differences in data processing speeds between the CPU and peripheral devices, ensuring smooth data flow.

Explanation

A combination of 16 bits is called a "word".

It is a standard unit of data used in computing to represent information.

• Bit: a single binary digit (0 or 1)
• Nibble: 4 bits
• Byte: 8 bits
• Word: 16 bits
• Double Word: 32 bits
