- What is a computer?
- Who invented it?
- What is are its main components?
- What are its main functions?
- What changes has it brought to our life?
Answer: The computer is one of 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: analog 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 complex mathematical problems quickly and accurately. This is why many people call “the computer an electronic brain”.
Paragraph on Computer
Question: Write a paragraph about ‘Computer.’ Your paragraph should include the answers to the following questions.
- What is one of the greatest advances in modern technology?
- What can a computer do?
- What can the fastest computer do?
- What are the various uses of the computer?
- Has the computer brought about revolutionary changes in our life?
Answer: The invention of the computer is one of the greatest advances in modern technology. It is a fairly recent invention. The computer is a substitute for the human brain. Computers are capable of doing extremely complicated work in all branches of learning. In a few minutes, a computer can perform calculations that a trained mathematician would need years to complete. The fastest computers can handle millions of problems in a few seconds. It can perform many operations at the same time without any confusion. Nowadays the computer has become very sophisticated and it can be put to various uses. It is being used in industries and in universities. It can run a business, play chess or even compose music. It has greatly benefited us in every sphere of life. It has brought about revolutionary changes in human civilization.
Computer Paragraph For All Class Students
A computer is an ultra-modern electronic device for storing and analyzing information fed into it. It has no capacity to do anything by itself. It works on the basis of commands given by the operator. The invention of the computer has a long history. The computer was not invented overnight. It took a long time and hard labor 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 the arithmetic unit. A computer performs three functions. Firstly, it receives data. Secondly. it processes data by various computations and the third 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 mankind. It is like Aladin’s magic lamp. It has lessened our workloads, saved time and energy, and made our life easy and comfortable. We can not go a single moment without computers. It is part and parcel of our daily life.
