Computer technology made several important impacts on our society and life. Many activities in our daily life can be performed easily by using a computer. It has saved a lot of time, reduced cost and solved specific problems. Some common application areas of computer are described below: Source : pixabay.com   1. Home: This is one of the major application fields of computer. Computers are playing a vital role at home, like other electronic devices such as television, radio, mobile phone, etc. Computers have also become the need of every person at home. Computers are used at home for writing a letter, listening to music, watching movies, drawing pictures, playing games, sending and getting email and information on the internet, keeping daily and monthly expenditure, and so on. Computers

A computer is a powerful machine. it has the capability to do any jobs with very quickly as well as 100% accuracy. So it has own lots of characteristics. some of them described below.

The operations on the data inside the computer are performed through the electronic circuits. The electronic circuit is designed in such a way that electrical signal travels at speed of light. A computer has the capability to do several complex calculations within a second. The time taken by the computer to perform an operation is called the processing speed. This processing speed of the computer is measured in MegaHertz (MHz) or GigaHertz (GHz) that is the speed of CPU. 1 Millisecond 1/1000th

A computer is an electronic machine that converts data into meaningful information by performing various actions on the data. A computer accepts the raw data from the user through input devices such as mouse keyboard etc processes them according to the given set of instructions, display the result as a human understandable form through an output device such as to monitor and printer, which called information and stores them for future references. Such operation performed by a computer is called the Information Processing Cycle or the basic working principle of the computer. The working principle of computer defined as below.

A computer is one of the most powerful devices or machine in the ever developed in the world. It can process a large amount of data within a second. So it has some important terms, they are described below. Source: pixabay.com Data: Data can e defined as any raw facts and figures or unprocessed mean need to be processed. Data can be figured out about a person, place, things, etc, which can be recorded and collected in the form of text, number, sound, image etc. Data itself do not give proper meaning without processing. For example ,the details of students (Roll No: 1, 2, 3, 4, Name : Dipak, Sabita, Messi, Ronaldo, Age: 20 , 23, 32, 35, Gender: male , female , Class: BBA, Msc, etc are data) . Above data can’t give exact meaning.  Processing:  The method or procedure of converting data i

This era is the technology era. We cannot imagine our life will be easier without technology. The most important technology in this era is the computer. A Computer is one of the most powerful and useful innovations in human history. Computer technology has brought tremendous effects in our daily life and enormous changes in the world. It has affected and reflected not only on the individual itself but also organization and society. With the use of the computer, people are suddenly able to perform an incredible amount of calculations at very high speed with almost 100% accuracy.  A computer plays a very important role to make human lives easier. It is becoming a fundamental need in our day to day regular activities. In this century, our life will be incomplete without the use of this wonder
