The word computer comes from the Greek compute word. Calculate the meaning of compute or calculate. And computer terminology means the calculator. But now the computer is not just a counting machine. Computer is an instrument that receives information and analyzes and presents through various processes. The development of civilization and its rapid progress now has strong influence on mathematics and computer. The first computer in Bangladesh came in 1964.

In the prehistoric era, various efforts of inventing the instruments of calculation are considered as computer history. In ancient times, man used to use mussels, gravel, rope gitt etc. to understand the number. Abacus, an ancient counting machine, is considered to be the first device in computer history. It was discovered in Babylon in 2400 BCE in Babylon. The composite machine has been replaced by the calculator in the abacus frame. Abacus was created as 450/500 BC in Egypt or in China as a counting instrument.
In 1616, Scottish mathematician John Nepeier used to print or use scarf or rubbish for work. These rocks are known as John Napier's bone. In 1642, 19 year old French scientist Blaise Pascal discovered the first mechanical calculator. He started the process of adding the tooth wheel or gear. 1671 German mathematician Gottfried von Libin Pascal created a more advanced mechanical calculator with the ability to divide and divide using the wheel and the rack, based on the machine. He named the machine Rechoning Mechine. Later in 1820, Thomas D. Kommer revised the recoding machine and made Libny's device popular.

The system is a collective effort of several integrated components that work for some common purposes. The components of computer systems are as follows: -
1.Hardware,
2.Software,
3.Humanware or user,
4.Data or information.
All the machines, parts and devices of the computer's outer shape are called hardware.
In order to solve the problem or perform the task, the command of the computer in a series consistently called programmake. The program or program set that makes the hardware efficient by creating relationships between computer hardware and user is software by itself.
All people associated with tasks such as collecting data, saving or checking data, programmed computer, writing computer programs, designing and recording systems, and coordinating between storage, software and hardware etc. are called Humanware.
Information is the smallest unit in data or data
The computer has lots of uses. | Its unique use in many areas, from home to business, scientific, etc. On top of all, it brings unique revolution It is also a unique partner in medical and human welfare In a word, the computer is a machine capable of almost all the work.
Computer is used for GIS technology. In this technology, various data is added to the map with the help of computer.
2.Using computer use in education: Using multimedia technology, there is a computer in class for teaching. Microsoft Excel is also used to publish results.
