Computers and culture | Computers and their role in human life have changed drastically since the 1950s. If 60 years ago computers did not play an important role in society‚ these day computers play a significant role in our lives. Initially‚ computers were big and awkward machines that were used just for keeping information and calculations. Throughout the last 50 years computers have become much smaller and much more sophisticated. If first computers were so large that they

to many important inventions. One of them is the computer. About a decade back‚ a computer was seen as a wonder machine. A few years later‚ this wonderful machine came closer to us as the Personal Computer (PC) entered the household scene. The computer today plays a significant role in our everybody’s life. Computers are used practically everywhere. The use of computer in our country in the past two decades has taken a big jump. Today computers do much more than simply compute‚ super market scanners

A computer system consists of mainly four basic units; namely input unit‚ storage unit‚ central processing unit and output unit. Central Processing unit further includes Arithmetic logic unit and control unit‚ as shown in the figure:. A computer performs five major operations or functions irrespective of its size and make. These are • it accepts data or instructions as input‚ • it stores data and instruction • it processes data as per the instructions‚ • it controls all operations inside a computer

History of the Computer Could you imagine life without computers? Not just computers but any smart device like your IPhone‚ IPad‚ Xbox etc. All of these devices are derived from the first unit known as the computer. Today’s society relies heavily on the computer and all of its functions. We essentially have the world at our fingertips whether it’s Googling anything you could possibly think of or plugging in an address and relying on a computer to get you there. If it wasn’t for the computer I would not

INTRODUCTION Computer is defined as a combination of electro-mechanical devices (Hardware) capable of accepting data or information‚ processing‚ storing‚ and providing output under the control of some instructions and commands called programs (Software). Computers are machines that perform tasks or calculation according to a set of instruction or programs. Introduce in 1940s the first fully electronic computers were huge machines that required teams of people to operate. Compared to those early

INTRODUCTION INTRODUCTION TO COMPUTER The term “Computer” is derived from the Latin word “Computare” which means “to compute” or “to calculate”‚ so it is considered to be calculating device. In fact‚ the main objective of inventing the computer was to create a fast calculating machine. But now-a-days more than 75% of non-mathematical or non-numerical work is carried out by the computers. Today‚ computer technology has spread to every sphere of existence of modern man‚ from railway reservation to

Applications of computers in various fields Computers have their application or utility everywhere. We find their applications in almost every sphere of life–particularly in fields where computations are required to be done at a very fast speed and where data is so complicated that the human brain finds it difficult to cope up with. As you must be aware‚ computer now-a-days are being used almost in every department to do the work at a greater speed and accuracy. They can keep the record of all

Computer Hacking The vast majority of the population of the U.S. does not consider computer hackers‚ who engage in illegal activity‚ as serious criminals. People do not consider computer hacking a serious crime because they are not directly affected. If a computer hacker taps into a network to gain wi-fi‚ no one will really care. But if a computer hacker hacks into a home network and steals credit card information to make purchases‚ then the severity of computer hacking is noticed. I believe
