Hardware components

Software components

Enumerate the two main components of a computer system

Hardware

is the physical component through which we interact with a computer

Hardware

They are made up of all those computer components/devices we can see or touch

Input Unit

Processing Unit

Storage Unit/Memory Unit

Enumerate the three functional units of a computer system

Input Unit

refers to a component or device that allows data or information to be entered into a computer system for processing

Processing Unit

processes acquired data into some meaningful information which could also be used as data for another processing session.

Central Processing Unit (CPU)

Example of a Processing Unit

Storage Unit/Memory Unit

refers to a component or system used to store and retrieve digital information in a computer or electronic device.

Main Memory

directly accessible by the CPU (Central processing Unit) and is used to store data that is actively being processed by the computer.

Random Access Memory (RAM)

Read-Only Memory (ROM)

Enumerate the Two types of Primary Memory

Random Access Memory (RAM)

It gives the CPU instant access to data and instructions that need to be temporarily stored

Read-Only Memory (ROM)

Is a type of computer memory that stores data permanently, meaning its contents even when power is turned off

Output Unit

this unit is for the devices used to show the result of processing operations.

Computer Software

A collection of programs, instructions, and data enabling a computer system to carry out particular activites or operations.

System Software

Application Software

enumerate the two categories of Computer Software

System Software

this software provides a platform for running software and managing computer hardware.

Application Software

This software is designed to perform specific tasks or cater to specific user needs
