Question

what is the role of following components of a computer system (1) control unit (2) arithmetic logic unit (3) ports and commectors (5) motherboard

Answer 1

1)The control unit tells the computer's memory, arithmetic/logicunit and input and output devices how to respond to the instructions that have been sent to the processor.
2)The ALU performs arithmetic and logic operations.
3)The port and connectors allow instructions and data to flow between the computer and the device.
4) The motherboard holds together many of the crucial components of a computer, including the central processing unit (CPU), memory and connectors for input and output devices.

Answer 2

Explanation:

Control unit:

The entire computer system is controlled and organized by the 'control unit'. It gets instructions from the 'program' stored in the 'main memory', interprets the 'instructions', and 'issues signals' that trigger them to be executed by other device units.

Arithmetic logic unit:

An 'arithmetic logic unit (ALU)' performs all arithmetic and logic-related processes that require to be performed on instruction words.

Port and Connector:

Port connects with a device unit so that data can be sent or retrieved from the computer by the peripheral.

A Connector is connected to a port and a cable in the system.

Motherboard:

The 'motherboard' is a 'printed circuit board' that transfers power to and between the 'CPU', 'RAM', and all other hardware components of the machine.
