Peripheral sharing refers to the practice of allowing multiple computers or devices to access and use the same peripheral devices, such as printers, scanners, or external hard drives. This is often achieved through a network connection, enabling users to share resources efficiently without needing individual devices for each computer. In a typical setup, a network printer can be connected to a router, allowing all computers on the network to send print jobs to it. This not only saves costs by reducing the number of devices needed but also simplifies management and maintenance of shared peripherals.
