Question: Nowadays, where we go. We observe the importance of the computer. The computer controls the different activities of life differently. In a word, we live in the computer era. In spite of this, sometimes it can not do something for us. Now write a paragraph describing what it can do and what it can not do for us.
Answer: The inventions of science has changed our lives rapidly. The computer is a fairly recent invention among them. The computer has become an essential part of our to day life. The computer is a special kind of electric machine that can perform mathematical calculations and process large masses of information at a great speed. A computer can do many things for us. It can perform calculations in a few minutes that trained mathematicians would need years to complete. The foulest computers can handle millions of problems in a few seconds. although a computer has greatly benefited the inhabitants of this planet it has some limitations. Computers can solve mathematical calculations quickly but cannot wash clothes. The computer also can do word processing but can not write itself. In spite of this, there is no doubt than the computer has advanced human civilization at a great speed. In fact, the computer is doing a great job by substituting the human brain and thus preventing the waste of time and energy of a human being.
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 computers. 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. The 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 an increasing unemployment problem. So, social and national problems are on the rise. Yet, we cannot deny the importance of the computer.
Paragraph On 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 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 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 for a single moment without computers. It is part and parcel of our daily life.
