CPU | MCQs

Explanation

The brain of the computer is the CPU

CPU stands for the central processing unit

The first commercial CPU was invented by Italian Physicist Federico Faggin

The first CPU was the Intel 404 released by Intel in 1971.

**

The five basic parts of a computer are:

1. the motherboard
2. central processing unit (CPU)
3. input-output units
4. memory (RAM and ROM)
5.  storage (SSD or HDD)

Explanation

CPU stands for Central Processing Unit

**

CPU is an example of hardware

A CPU contains  A control unit and an arithmetic logic unit

The CPU and memory are located on Motherboard.

The motherboard holds CPU, RAM and ROM chips, etc.

**

 Buses are connections or gateways between the CPU and other devices.

Explanation

 A computer system consists of a computer case, a power supply unit, a motherboard, a central processing unit, main memory, and a hard disk drive.

Input devices include a keyboard, mouse, microphone, video camera, and image scanner.

AGM 07.5.23

Explanation

Explanation

The CPU and memory are located on the motherboard.

The motherboard's job is to connect all hardware components together.

The motherboard's a thin plate that holds the:

1. CPU,
2. Memory,
3. Connectors for the hard drive,
4. Optical drives.

Explanation

CPU speed is typically measured in Megahertz (MHz) or Gigahertz (GHz).

It indicating millions/billions of cycles per second.

Mbps measures internet speed.

Mbytes measure data size.

Explanation

A bus is a high-speed internal connection that sends data and control signals between the processor and other components.

The amount of data a data bus can transfer is known as bandwidth. 

1. Data bus: A bidirectional communication path that transfers data between the CPU, memory, and input/output devices.
2. Address bus: Transmits the physical location (address) of data to be accessed or written by the CPU.
3. Control bus: Transfers control signals for coordinating the overall system's operation.

Explanation

RAM stands for Random Access Memory.

Explanation

The Control Unit directs all operations in the CPU.

The ALU (Arithmetic Logic Unit) performs arithmetic and logical operations.
