A Short History of Computers
⭐ MasteredEarly computers were as big as rooms. Transistors and microchips made them smaller, faster and cheaper until we could hold them in our hands.
Ada Lovelace is often called the first computer programmer.
All about A Short History of Computers
Early computers were enormous machines that filled entire rooms. They used thousands of vacuum tubes, which generated lots of heat and broke down often. Early calculations were done with punched cards and mechanical calculators.
The invention of the transistor in 1947 and the microchip in the late 1950s made computers smaller, faster and cheaper. Over time, computers became personal machines, and today a smartphone holds more computing power than many early computers.

Frequently asked questions about A Short History of Computers
What is a transistor?
A tiny electronic switch that can amplify or switch electronic signals, and it is the building block of computer chips.
Who is considered the first computer programmer?
Ada Lovelace wrote notes in the 1840s about Charles Babbage's Analytical Engine, which included what is often considered the first algorithm for a machine.
What is a microchip?
A small piece of silicon containing many tiny electronic components, which carries out computing tasks.
