Digital Computers

There are two fundamentally different types of computers: analog and digital. In current usage, the term “computer” usually refers to high-speed digital computers. These computers are playing an increasing role in all branches of economy.
Digital computers are based on manipulating discrete binary digits (1s and 0s). They are more effective than analog computers: they are faster; they can transfer huge data bases more accurately; and their coded binary data are easier to store and retrieve than analog signals.
For all their apparent complexity, digital computers are considered to be simple machines. Digital computers are able to recognize only two states in each of its millions of switches, “on” or “off”, or high voltage or low voltage. By assigning binary numbers to there states, 1 for “on” and 0 for “off”, and linking many switches together, a computer can represent any type of data from numbers to letters and musical notes. It is this process of recognizing signals that is known as digitization.
The power of computers influences the characteristics of memory-storage devices. Most digital computers store data both internally, in what is called main memory, and externally, on auxiliary storage units. As a computer processes data and instructions, it temporarily stores information internally on special memory microchips.
Output devices let a user see the results of the computer’s data processing. Being the most commonly used output device, the monitor accepts video signals from a computer and shows different kinds of information such as text, formulas and graphics on its screen. With the help of various printers information stored in one of the computer’s memory systems can be easily printed on paper in a desired number of copies.
Programs, also called software, are detailed sequences of instructions that direct the computer hardware to perform useful operations. In large corporations software is often written by groups of experienced programmers, each person focusing on a specific aspect of the total project. For this reason, scientific and industrial software sometimes costs much more than do the computers on which the programs run.
