History of Electronic Computers

The history of electronic computers began many years ago. At first, people used fingers and stones to count. Later, they built machines to solve big problems. Over time, these machines improved and became the computers we use today.

The first electronic computer was called ENIAC.
It was made in 1946 in the USA.
ENIAC was very big, almost the size of a whole room.
It could only do simple math.
With time, computers became smaller, faster, and smarter.
In the 1970s and 1980s, personal computers (PCs) were made for home and office use.
Later, laptops and mobile devices were also invented.
Today, computers are used everywhere, in schools, homes, shops, hospitals, and even in smartphones.

Main Features of an Electronic Computer

Output: The result is shown using output devices like a monitor, printer, or speakers.

Basic Parts of an Electronic Computer

An electronic computer is made up of different parts that work together. Each part has its own job to help the computer work properly. Here are the main parts:

Input Devices: These help us give data or commands to the computer. Example: keyboard, mouse.
CPU (Processor): This is the brain of the computer. It processes all the data and controls the work.
Memory (RAM, Storage): RAM helps the computer work faster. Storage (like hard drives) saves files and data.
Output Devices: These show us the result of the computer’s work. Example: monitor, printer.

Types of Electronic Computers

There are different types of electronic computers used for different needs. Some are small and used at home, while others are very big and used by large companies or scientists.

Microcomputer (PC): A small computer used in homes, schools, and offices. It is also called a personal computer.
Laptop: A portable computer that you can carry and use anywhere. It runs on a battery.
Tablet: A small, touchscreen computer, easy to carry and use with fingers.
Supercomputer: A very powerful computer used for big tasks like weather studies or space research.
Mainframe: A large computer used by banks, airlines, and big companies to handle lots of data.
