The Evolution Of The Computer Introduction The evolution of electronic computers over a period of time can be traced effectively dividing this period into various generations. Each generation is characterized by a major technological development that fundamentally changed the way computers operated. These helped to develop smaller‚ cheaper‚ powerful‚ efficient and reliable devices. Today‚ life has become indispensable without a computer. You find computerization in almost every sphere and industry

How many inventions in your lifetime can you think of that have changed everything in our society today? Computers have taken over today ’s society. From everyday tasks to moving satellites in space‚ PCs have revolutionized almost everything in our society. Computers weren ’t always this complicated though‚ and were around a long time before anyone even knew what the word "computer" meant. The Abacus was the first known machine developed to help perform mathematical equations. From what researchers

Throughout the last 25 years‚ computers have evolved from being low speed simple machines to high speed behemoths while still remaining affordable. This quantum leap in their performance was made possible by integration of new technology‚ some of which was made possible through the use of computers themselves. The computers have evolved considerably from being basic set of components made up of Integrated Circuits (ICs) to have a much complex architecture involving microprocessors with millions of

As computers have become less expensive‚ they have been purchased by more and more families for their homes. As a result‚ more youths and children have started to use computers at earlier ages. Even if there is not a computer available at home‚ it’s guaranteed that the youth will come into contact with a computer somewhere else‚ such as school. This may have not been the case a couple decades ago and with that said‚ computers have been evolving (and still are). The evolution of computers is all possible

data and each situation warrants a different method. There can be several different ways to input the information and it can be done in an automatic fashion‚ as with a computer‚ or it can be done manually‚ as with a human writing the information down. For instance‚ printed questionnaires would best use a special scanning device called an optical data reader that uses optical mark recognition (OMR); when people complete the OMR form using pencils to fill in boxes on OMR paper an optical mark reader

Introduction Computer is a machine that can be programmed to accept data (input) process it into useful information (output) and stored it away (in a secondary storage device) for safekeeping or later reuse. The processing input to output is directly by the software but performed by the hardware. To function‚ a computer system requires four main aspect of data handling: Input Processing Output Storage Secondary

1. Scanning devices Optical Scanners An optical scanner is a hardware input device that allows a user to take an image or text and convert it into a digital file‚ allowing the computer to read or display the scanned object. Features of the optical scanner include-its design‚ software compatibility‚ type of feeder‚ speed‚ resolution‚ etc. Some advantages of the optical scanner include : • Easy to use • Continuous‚ detailed‚ and scaled true-colour images for documentation and interpretation

history of computers and evolution Computers have been around a lot longer than many people might imagine. The word "computer" has changed meaning over decades‚ but the electronic computer that we think of in modern times developed throughout the second half of the 20th century. Its popularity as a household item surged in the 1980s following the arrival of operating systems by Apple and Microsoft that mixed graphics and text‚ replacing the text-only systems of the 1970s. By the 1990s‚ computers incorporated
