liitännäislaitteita

Liitännäislaitteita, known in English as peripherals, are external devices that connect to a computer system to expand its functionality or provide input/output capabilities. They are not an integral part of the core computer but are essential for many tasks. These devices can be broadly categorized into input devices, output devices, and storage devices.

Input devices allow users to send data and commands to the computer. Common examples include keyboards, mice, touchscreens, scanners, and microphones. Keyboards are used for typing text and commands, while mice are used for pointing and selecting. Scanners convert physical documents into digital images, and microphones capture audio.

Output devices present information from the computer to the user. Monitors are the most common output devices, displaying visual information. Printers produce hard copies of digital documents. Speakers and headphones convert digital audio signals into sound.

Storage devices, while sometimes integrated, often function as peripherals. External hard drives, USB flash drives, and memory cards provide additional space for storing data beyond the computer's internal storage. These devices allow for portability and backup of important files.

Networking devices such as modems and routers, although crucial for connectivity, can also be considered peripherals as they enable communication with external networks. The variety of liitännäislaitteita continues to grow, enhancing the capabilities and user experience of computing systems in numerous ways.
