Encyclopedia Definition of: programmable computer. programmable computer. A redundant term, because what makes a computer a computer is that it follows a set of instructions. Many electronic devices are computers that perform only one operation, but they are still following instructions that reside permanently in the unit. In order to contrast a machine that can be reprogrammed with one that cannot, the computer is user programmable would be a better choice of words. See computer.

Introduction to Computers The Big Picture. Software is actually a computer program. To be more specific, a program is a set of step-by-step instructions that directs the computer to do the tasks you want it to do and to produce the results you want. A computer programmer is a person who writes programs.Most of us do not write programs, we use programs written by someone else.o function, a computer system requires four main aspects of data handling: input, processing, output, and storage. The hardware responsible for these four areas operates as follows: 1  Input devices accept data in a form that the computer can use; they then send the data to the processing unit.

Programmable logic controller More recently, PLCs are programmed using application software on personal computers, which now represent the logic in graphic form instead of character symbols. The computer is connected to the PLC through Ethernet, RS-232, RS-485, or RS-422 cabling.pecial-purpose I/O modules may be used where the scan time of the PLC is too long to allow predictable performance. Precision timing modules, or counter modules for use with shaft encoders, are used where the scan time would be too long to reliably count pulses or detect the sense of rotation of an encoder.

- For other uses, see Computer (disambiguation) and Computer system (disambiguation). A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a program, make computers very applicable to a wide range of tasks. Such computers are used as control systems for a very wide variety of industrial and consumer devices.
