Välisseadmed

Välisseadmed, or external devices, are hardware components that connect to a computer but are not part of the core computer system itself. They extend the functionality of a computer, allowing users to interact with it or expanding its capabilities. These devices communicate with the computer through various interfaces, such as USB, Bluetooth, or dedicated ports.

Common categories of välisseadmed include input devices, output devices, and storage devices. Input devices allow users to enter data and commands into the computer. Examples include keyboards, mice, scanners, and webcams. Output devices display or present information processed by the computer. These encompass monitors, printers, speakers, and projectors. Storage devices, while often internal, can also be external, providing additional space to store data. External hard drives, USB flash drives, and memory cards fall into this category.

The purpose of välisseadmed is to enhance user experience, increase productivity, and provide specialized functionalities that the computer's internal components might not offer. For instance, a printer allows for physical copies of digital documents, and a graphics tablet enables precise digital drawing. The diversity of välisseadmed means that users can customize their computing environment to suit a wide range of needs and activities, from gaming and entertainment to professional design and data management.
