port
porte f

The integrated circuit port, or port, that allows a computer to interface
peripherals.
See user port.

PPM
PPM

Pages per minute. Abbreviation for pages per minute, a measure of the output speed of a printer.

Prestel
Prestel

Prestel. The name of the British Telecommunications Corporation's viewdata service, which was designed for the home market and for use during evenings, weekends and holidays when telephone lines are less frequent. However, it is mainly used by businesses today. Signals from one of the Prestel computers (all linked together) are transmitted via telephone to a television screen. There are now some 200,000 different pages available covering topics as diverse as choosing a bottle of wine or British train times. In-formation providers buy pages to display their products or information. Users have to pay for the telephone line and computer time when using the system, and may also have to pay for a page that Telecom collects for the information companies, but most pages are free. Other special data systems can be obtained through Prestel. Some pages consist of software, and one can obtain this telesoftware by connecting to British Telecom microcomputers via compatible modems.

printed circuit board (PCB)
circuit m imrimé

Printed circuit board. A thin board on which electronic components are soldered, often with wires pushed through one end and soldered to the other end, which contains the printed circuit. A printed circuit consists of metal strips that connect one component to another. Several of these boards can be used in a microcomputer, one carrying the microprocessor, another a set of memory chips, another for high resolution graphics and for controlling disk drives, etc.

Such a set of boards can be installed on the motherboard, or connected by a multi-wire cable.

It is worth noting that the printed circuit board allows for more complex connections than wired circuits. Double-sided printed circuit boards are also available.

printer
imprimante f

Printer. This device, or hard copy, is used to make a printed copy, peripheral, of the computer output. The printer may be mechanical, impact, or non-impact. Impact printers include dot matrix printers, chain printers, ribbon printers, belt printers, metal ring printers, or daisywheel printers. These printers are noisier and slower but have the advantage of producing carbon copies during printing. Non-impact printers use thermal, electrostatic, laser, magnetic, or ink-jet technologies. They are more suitable for graphic work, although some impact printers can also produce such work. In general, the most popular printers today are dot matrix and daisywheel printers. The speeds of some types of printers are:

Teleprinter 10 - 30 characters / second
Calligraphy printer 50 characters / second
Dotted printer 80 characters / second
Inkjet printer 200 characters / second
Line printer 1000 lines / minute
Laser printer with xerography 20 pages / minute

program
programme m

A program is a set of instructions that the computer executes. Whatever the language in which the program is written, the machine follows the instructions, one after the other and in order. Writing a program has five basic steps:

(1) Understanding the problem and solving it.

(2) Developing a context statement or solution plan.

(3) Coding the program.

(4) Writing documentation.

(5) Experimenting and testing.

Using the top-down approach in structured programming, the first three steps are applied to the sections, resulting in a series of programs, each of which has a problem to solve.
