Computer Essay – The computer is the latest & the most excellent miracle of modern science. We now live in a computer age; the computer has become our friend, philosopher, and guide. The word computer is derived from the verb ‘Compute’ meaning to reckon or calculate something.
In -1643 B. Pascal, a French mathematician invented the mechanical calculating machine. In 1812 Charles Barrage invented the improved model of the mechanical computer. The first electromechanical computer was made jointly by Harvard University & IBM Company in 1946. Since 1971 major improvements in computer technology have led to the development of modern-day computers.
Computers are classified according to the size, speed & the internal structure such as the supercomputer, mainframe computer & microcomputer. PC (personal computers) are the most popularly used computers in the world.
The main aspects of a computer are hardware & software. Hardware is the machine itself consisting of RAM, central processing unit (CPU) and hard disk. The software is the program-es which help the hardware to function according to users demand. The most commonly used software is DOS and Microsoft Windows. A PC comprises a keyboard, system unit and monitor.
Scientifically computer is an electronic device that receives data which are fed into it, stores the data inside of it and processes the data according to instructions.
The computer can receive numerous data & instructions and perform millions of calculation within seconds. It is capable of manipulating the input data and make a conclusion according to instructions. Computers are widely used in medical diagnosis & treatment, Banks, Govt. & private offices, NGO’s, business houses, publishing, etc. Computers are also used in remitting messages through e-mail.
The computer has come to our country with immense possibilities. Presently people are becoming quite dependent on the computer for their day-to-day work, for word processing, data analysis, preparation of spread-sheets, inter-office mail and international communication. So, the conscious and learned people should take up the steps to familiarize the uses of the computer to the general people at large. Consequently, the countrymen will be benefited.

Computer Essay Paragraph and Composition – From the very beginning of man’s civilization man has been advancing towards
The literal meaning of the word ‘computer’ is ‘an instrument that computes or does various calculations’. Fundamentally it is a calculating machine. It can perform various calculations like addition, subtraction, division, multiplication and soon. In fact, it can receive innumerable data and instructions and perform thousands of calculations within seconds and then give the results. Apart from doing mathematical calculations, a computer has surprising capabilites of manipulating the input data according to logic and making conclusions as per instructions. The work which a man would otherwise do in thousands of days is done by the computer within minutes or hours.
The modern computer is a very modern electronic instrument. But in the primary phase of its evolution, it was not so. It has a history of its evolution. In 1643 the French mathematician B. Pascal invented the mechanical calculating machine for performing some arithmetic calculations. In 1671 Lebonese and in 1812 Charles Babbage invented two improved models of mechanical compnuters. The first electro-mechanical computer was made jontly by the Harvard university and the IBM company in 1944. At last the electronic computer came into existence in 1946. However, the major improvements in the computer technology was possible only after 1971. At present there have been unimaginable improvements in this technology.
A computer has two main aspects: The hardware and the software. The hardware is the machine itself, and the software is a combination of various symbolic instructions or codes, better known as the
The hardware can be thought of as the skeleton and the software, the flesh and blood- if the whole computers were to be imagined of as a human being. The software or the programs virtually help the hardware function the way the user wants it to. The programs are of two types one is the operating system and the other, the application program.
The operating system coordinates various functions of the hardware as well as activates the applications programs. The applications programs, on the other hand, perform a mathematical calculation. The whole system of the computer is the combination of these programs and hardware systems.
The coded set of instructions that are stored in the memory of the computer for performing various calculations is called the computer program. A computer uses the binary method for its internal calculations. The compiler of the applications programs translate into the computer language codes any instructions given to it by the user.
The computer can be classified according to its size speed, and internal structure. We can be based on these criteria of classification, identify various types of computers such as the super -computer, the mainframe, the mini-computer, and the micro-computer. The form and shape or size of computers may vary, but in each of the causes the main working principle or method is the same for all types of computers.
This computer is perhaps the strongest gift of science. It is helping us in business, research, management and, administration, and virtually in all fields of modern life. Its importance is so great that if it were taken out from men’s civilization, the entire process of civilization would come to a standstill.
To speak more specifically, the computer has proved to be the best aid to our thinking process, observation, the control of the economy and production processes, printing, translation, research in the laboratory and in the field and what not. In a word, the
The computer has come to our country with immense possibilities too. Now it is giving its blessed touch in almost every sphere of life. But the general people are completely ignorant of the magic power and potential of this small machine. Therefore, if it can be familiarized to the general people at large, we will get more and more utility from it.

There are five components of a computer. They are the input unit, the output unit, the memory unit, the control unit, and the arithmetic unit.
A computer performs three functions, such as receiving data, processing data and emitting data.
The uses of computer beggar description in our day to day life. It performs a great service to mankind. It has really saved time, effort, labor and made our life easy and comfortable. It is also a media of education. Many things are learned by computer within the shortest period of time. Results of examinations are prepared accurately with the help of computer rapidly. Computers are widely used in medical diagnosis and treatment.
Nowadays computer is used in commerce and trade. It is also used to prepare documents, to make lists of goods, store information and to prepare budget etc. The share market can be counted instantly by the computer. In printing, thousands of books are composed with the help of the computer within a very short time. The computer is now used to control mills, factories, and various types of industries. Trains and plans are run by the computer.
The computer is a source of great income. Many developed and advanced countries export software and hardware and earn a lot of money. Even Bangladeshi people earn much money throughout computer by doing freelancing. It has also lessened our unemployment problem.
Everything has its dark sides. It causes diseases like Restitutive stress injury and weakens the eyesight of the operators. It has also a bad effect on young children and students. They play games on the computer and thus neglect their studies. It is like an addiction to many of them. Nowadays the hackers hake the security of the government computers to get their confidential files and documents to perform their evil motives. Even the security of many international organizations (Interpol, CIA) and bank accounts are being disrupted throughout hacking.
The computer has come and changed the outdated (সেকেলে) mindset (বদ্ধমূলধারণা). We can not do a single moment without computers. Now the computer has become a part and parcel in our everyday life. Finally, we can say that the benefits of the computer should come down to the grassroots levels.
