Short Paragraph On Computer

Question:

  1. What is a computer?
  2. Who invented it?
  3. What is are its main components?
  4. What are its main functions?
  5. What changes has it brought to our life?

Answer: the computer is one the most wonderful inventions of modern science. It is fairly a recent invention. It has now become a part and parcel of day-to-day life. The computer was invented by an English mathematician called Charles Babbage. Computers are two basic types: analogue and digital. Analog: computers deal with physical qualities and digital computers deal with numbers. Computers have five major components; input, store, control, processing and output. They mainly perform the functions of addition, subtraction, multiplication, division and comparison. Every computer has a language of its own. It is called a programming language. The computer has brought about a revolutionary change in our life. It can solve the complex mathematical problems quickly and accurately. This is why many people call “the computer an electronic brain”.

Paragraph On Computer

The computer is an electric brain. Charles Babbage, a British mathematician, thought about this electric brain first. Later an American scientist, Howard Akin invented the computer in 1937. There are two kinds of computer. They are Analogue Computer and Digital Computer. A computer mainly does three functions. These are data receiving, data processing and delivery of data. A computer has some units. The units have respective functions. It has a memory unit. It helps to store all the data. The input and output units help to receive information. Its arithmetic unit can do a complicated calculation so easily. Now the computer is used in all walks of our life. It is used in education. It is used in printing books, preparing lessons etc. The computer plays an important role in diagnosis. The computer helps print and electronic media. Business, commerce, mills, factories, agriculture sector use a computer. Modern banking system greatly depends on the computer. It has some demerits. As it is doing almost every work, we are becoming idle. Besides, it is increasing unemployment problem. So, social and national problems are on the rise. Yet, we cannot deny the importance of computer.

Computer

The computer is an update electronic device for storing and analyzing information fed into it. It has no capacity to do anything by itself. It works based on commands given by the operator. The invention of the computer has a long history. The computer was not invented overnight. It takes a long time and hard labour to invent the computer. A computer consists of five major components. They are the input unit, the output unit, the memory unit, the control unit and arithmetic unit. A computer performs three functions. Firstly, it receives data. Secondly, it processes 700 data by various computations and the thirdly is that it emits data. Every computer has a machine language of its own and accordingly it works. Machine language is not fixed. It varies from machine to machine. The computer is of great use to us. It renders great service to humankind. It is like a magic lamp. It has lessened our workloads, saved time and energy and made our life easy and comfortable. We cannot go a single moment without computers. It is part and parcel of our daily life.
