TOPIC 4: TYPES OF INPUT DEVICES PRESS AND TALK

• An input-output device is a component of a typical computer architecture that allows the computer to interact with the outside world, specifically with users.
• They are divided as follows:
• - Input device
• - Output device
• - Input/output devices - portable media components (disks), two-way interfaces (various computer ports and network interfaces).
•  
• Input device. Input devices mainly include non-electrical signals (position of electromagnetic devices, pressure, viscosity, speed, acceleration, lighting, temperature, humidity, movement, quantitative values, etc.) received by the processor for digital processing, and sensors that convert electrical quantities into electrical signals. .

• Output devices. Output devices are those that convert electronic digital information into the form needed to obtain the desired result, both non-electrical (mechanical, thermal, optical, sound) and electrical (transformer, heater, electromotive relay) form. can convert.

• Keyboard
• A keyboard is a lever button located in a certain order, designed for entering information or controlling a device. Usually, the keys are pressed with the fingers. But there will also be touch keyboards.

5 SUBJECT: Information input and output devices

• Enter
• A computer is a universal device for data processing. In order for a computer to process information, it has to be entered in some way. Special devices have been created for entering information - primarily keyboards, CD-ROMs. Once in the computer, the data is processed and then the ability to extract this data is realized, i.e. the user has the ability to visually perceive information. Main devices - monitor, video adapter and printer are used to display information. After entering and processing information, it can be stored, for which hard disk, magnetic disks and optical data storage devices were created. This review course covers the topic "Information Input / Output Devices".
• Information output devices - These are devices that convert information from machine language into human-perceivable forms. Information output devices include: monitor, video card, printer, plotter, projector, speakers.
