AI overview

A peripheral is an auxiliary hardware device that connects to a computer to help it send information outside or receive input from the user, such as a keyboard, mouse, or printer. Peripherals matter because they extend what a computer can do—allowing you to interact with it and access its data—even though they aren't essential core components of the computer itself.

外部裝置又叫周边设备(英語:peripheral devices 或 peripherals)、外部设备(简称外设),是电子计算机中位于机箱之外、能够通电并可以不依赖计算机进行正常的独立或半独立运行的硬件。外部设备通常被用来扩展计算机系统的功能,包括输入输出设备(如显示器、键盘、鼠标、音箱、打印机、扫描仪、摄像头、话筒 、数码绘图板等)、网络设备(如USB网卡、网路交换器、无线接入点、移动宽带调制解调器等)和外置存储设备(如移动硬盘、软盘或光盘驱动器,和闪存盘、储存卡读卡器、MP3/MP4播放器以及USB集线器等USB便携设备),以及不间断电源、外置显卡和外置声卡等增强系统性能和稳定性的辅助硬件。正常的计算机即使去除这些外置设备,也能进入准备工作的就绪状态,虽然对使用者来说操作这样的计算机可能变得困难或十分不方便。 * 鍵盤 * 滑鼠 * 光碟機 * 儲存卡讀卡機 * 叉電線
