What is the primary role of computer ports?

The primary role of computer ports is to connect additional devices and peripherals to a computer. Ports serve as interfaces through which external devices such as keyboards, mice, printers, external hard drives, and other hardware can communicate with the computer's internal components. By providing this connectivity, ports enable users to expand the functionality of their computers, facilitating a wide range of tasks such as data input, output, and storage enhancements.

While managing power supply, internal communication, and temporary data storage are also essential functions within a computer system, they do not specifically relate to the role of ports. Managing power typically involves power supply units and circuits rather than the ports themselves. Internal communication occurs through the motherboard and various buses within the computer, which facilitate data transfer between the CPU and components. Temporary data storage is handled by RAM, where data is quickly accessed and processed while the computer is in use. Thus, the true function of ports focuses on establishing connections with external devices, making option B the most accurate reflection of their primary role.
