Across the last two decades, the basic computer knowledge revolution has changed people’s lives all over the world. It has boosted productivity in businesses as diverse as deep-sea drilling and fashion design, facilitated global communication, and put the world’s knowledge at your fingertips. Knowing how to operate a computer has practically become a basic survival skill as the world becomes more digital.
1. Understanding the Basics of Computer Hardware
Chief Focus: Hard Drive, CPU, Memory
Computers are just that: machines. They, like other machines, are made up of a variety of moving and non-moving parts that allow them to function in a variety of ways. These hardware components have been methodically designed over time to accomplish their specific functions at varying speeds, capacities, and abilities.

To that aim, there are a variety of computer kinds. A gaming PC, a media center, or a work computer are all possibilities.
If an office worker doesn’t need to store much data other than simple text files, their work computer may have a modest hard disc.
We’ll go over the major components below and talk a little about what each one does.
- Motherboard. The motherboard is home to BIOS, or Basic Input/Output System, the very basic piece of software that comes with a computer, in addition to giving space for the hard drive, CPU, and other components we haven’t addressed yet to plug into. When you power on a computer for the first time, it must boot before it can load the operating system. Users can also connect accessories such as a mouse and keyboard to the motherboard.
- Graphics Card. The graphics card, often known as a video card, is the component that displays images on your computer’s monitor or display. Although some motherboards include built-in, onboard, or integrated video cards, the quality is inferior to that of a dedicated video card purchased separately and installed on the motherboard.
- Power Supply Unit. Remember that computers are electronic devices that cannot function without power! Overheating can harm your computer’s performance and put its components at risk, thus power supply units come with fans to help cool it down.
- Hard Drive. Since we’re already talking about hard discs, let’s go over what they are. For non-techies, this is perhaps the most familiar piece of computer hardware, but don’t worry if you don’t know what it is. A hard drive is a storage device for a computer.
What is a Computer?
A computer is a general-purpose machine that accepts (inputs), stores, manipulates (outputs), and generates (outputs) data in the form of numbers, text, pictures, speech, video files, or electrical impulses in accordance with programme instructions.
- Charles Babbage is known as the “Father of the Computer.”Alan Turing, the father of the modern computer.
- John Von Neumann’s Basic Computer Architecture (1947-49).
- Lady Ada Lovelace was the first programmer (1880).
- ENIAC (1946) by J.P. Eckert and J.W. Mauchly was the first electronic computer.
- IBM introduced the first computer for the home user in 1981.
Basic Parts of a Computer System
A computer system consists of a system unit and any associated software (such as Office 2016, Windows 10, and so on) as well as peripheral devices (such as a mouse, keyboard, monitor, and printer).
Computer monitor — A computer-processed information (text, image, video, etc.) is displayed on a display screen.
Keyboard – an input device (a set of typewriter-style keys) that allows a user to type characters (letters, numbers, symbols, and so on) into a computer
Mouse – a hand-held pointing device that can move a cursor (pointer) around on a display screen.
Trackpad (or touchpad) – On a laptop or other computer, a small flat surface that performs the same functions as a mouse (a trackpad is a built-in mouse).
