What User is
A term that defines the online audience, it also refers to anyone who uses a computer. The term "users" rubs some people the wrong way because, in the past, if you said you were a user, it meant you were habitually consuming an illicit drug. Nowadays, a user is a person who is online. It comes from techies, who refer to people as "computer users." Historical reference: The word "users" is not yet in the American Heritage Dictionary, but the word "user-friendly" made it; perhaps because we are the first group ever to be online users.
Historical Reference: The word "users" isn't in the American Heritage Dictionary but the word "user-friendly" made it. The term "use" is defined in a variety of ways which, when taken in the context of "Internet users," can be quite poignant: "to put into service, to employ, to exploit, to consume completely, the privilege of using something," and so on. In the past you'd never refer to yourself as "a user" unless you were drug addicted... does this say something about how we're all getting addicted to the online world?
The meaning of Computer
A device that runs programs for displaying and manipulating text, graphics, symbols, audio, video, and numbers.
A computer accepts information in the form of digital data. Complex computers also include the means for storing data (including software programs). A program may be built into the computer (in the logic circuitry, located on the microprocessors), or may be loaded into the computer's storage and then started by an administrator or user. Today's computers have both kinds of programming.
Most histories of the modern computer begin with the Analytical Engine envisioned by Charles Babbage, who followed the mathematical ideas of George Boole (see: Boolean logic), the mathematician who first stated the principles of logic inherent in today's digital computer. Babbage's assistant and collaborator, Ada Lovelace, is said to have introduced the ideas of program loops and subroutines and she is sometimes considered the first programmer.
Modern computers inherently follow the ideas of the stored program laid out by John von Neumann in 1945. Essentially, the program is read by the computer one instruction at a time; an operation is performed, then the computer reads the next instruction, and so on.
Prior to the PC, which is small and affordable, computers were large and expensive. Companies enabled multiple users to share the computer resources through attached terminals. Starting in the late 1980's, technological advances made it feasible to build smaller-sized computers that individuals could use independently, whether at work or at home. These were then "networked into" the larger system.
Recently, computers and programs have been devised that allow multiple programs (and computers) to work on the same problem, at the same time, in parallel (see: network computing). For many users, though, a computer acts only as a "glorified typewriter," used to cut-and-paste objects and to save documents. But computers can also perform a variety of other tasks, such as accounting and desktop publishing.
A computer system includes peripherals, such as hard and floppy disk drives, a monitor, a mouse, the operating system, software, and a printer. All of these components are designed to work together. You need a computer to access the Internet, browse the Web, and send or receive e-mail, among other things.
