What is the primary function of a cable in computer systems?

The primary function of a cable in computer systems is to connect an external peripheral device to a port. Cables serve as the crucial physical medium that facilitates data transfer between various components of a computer, such as between the computer and printers, monitors, or external storage devices. By establishing this connection, cables enable communication and interaction between the computer and peripheral devices, allowing for the exchange of data, power, and signals.

This role is essential for expanding the capabilities of a computer system, as it allows users to utilize additional hardware and accessories to enhance functionality. For example, USB cables connect devices like keyboards and mice, while HDMI or DisplayPort cables link monitors to computers, ensuring that the peripherals function effectively.

Other choices revolve around different functionalities: for instance, the storage of data and programs pertains to storage devices; powering the motherboard relates to power supply connections, and enhancing internet speed concerns networking equipment rather than the physical connection facilitated by cables.
