desktop computer From the days of adding machines and typewriters to the present day, the computer has revolutionized the way information is processed.  First developed during the early to mid-1900s, computers can process information much faster and more accurately than human beings.  Early mainframe computers were large and expensive; they also required specially designed rooms where temperature and humidity were carefully controlled.

Over the years, miniaturization of electronic components and the use of integrated circuits, as well as the development of microprocessor chips, led to smaller, faster, and less expensive computers.  Today, the ubiquitous personal computer has provided a remarkable amount of computing power for much of the world's population.  In the United States, we now have computers on virtually every desk as well as laptops to accompany us everywhere else.  With the Internet, we can use these amazing devices to quickly access a seemingly endless variety of information.

Computers are electronic devices that can collect, store, process, and disseminate information.  A computer consists of a system board (or motherboard) and a central processing unit (CPU), as well as volatile memory chips (RAM) and non-volatile storage devices such as disk drives.  A computer also requires peripheral devices such as a mouse, keyboard, and scanner for collecting data and a monitor, printer, speaker, or projector for disseminating information.

Computer programmers instruct computers, by means of a series of precise instructions called software, to process data in a specified manner.  Using software programs, raw data can be converted into valuable information.  This information can be used to increase productivity, enhance the quality of products and services, and gain competitive advantages.  However, as computers have become more widely interconnected, via the Internet, privacy and security concerns are becoming a major issue for the computer industry.
