COMPUTER: History, Facts & Information About This Device

A computer – Here is the history, facts, and necessary information about this life-changing device that you probably didn’t know.

A computer is an electronic device that processes and stores data, performing a variety of tasks based on instructions provided by users or pre-programmed software. It is a versatile tool that can handle calculations, store and retrieve information, communicate with other devices, and various applications.

Key components of a computer include the Central Processing Unit (CPU), which acts as the brain and performs calculations, memory (RAM) for quick data access, storage devices like hard drives or solid-state drives for long-term data retention, and input/output devices such as keyboards, mice, monitors, and printers for user interaction.


Computers operate on software, which includes programs, applications, and the operating system that manages hardware resources and enables users to interact with the computer.

This device can connect to the internet, a vast network that allows users to access information, communicate with others, and engage in various online activities.

Computers come in various forms, including desktops, laptops, tablets, and smartphones, each designed for specific purposes and user preferences. They have become indispensable in modern life, influencing how we work, communicate, learn, and entertain ourselves.


Before electronic computers, people used mechanical devices for calculations. One notable invention was Blaise Pascal’s Pascaline, a mechanical calculator, in the 17th century. Later, Charles Babbage envisioned the Analytical Engine, a steam-powered device considered the “first computer.”

In the 1940s, the Electronic Numerical Integrator and Computer (ENIAC), was born. In 1970s, companies like Apple and IBM introduced machines that individuals could use at home or work.

The 1990s brought the internet, connecting computers worldwide. With the World Wide Web, communication and information-sharing became more accessible. It gives birth to the user-friendly operating systems like Windows and macOS.

In the 21st century, smartphones and tablets exist, marking the era of mobile computing. These devices, with their touchscreens and powerful processors, allow us to carry the capabilities of a computer in our pockets.

Nowadays, computers are not just tools, they are becoming smarter with artificial intelligence (AI) that can help shape the future.
