Which of the following is a type of socket that allows cables to be connected to a computer system without opening the case?

The correct choice, which is ports, refers to the interfaces on a computer that enable external devices to connect without the need to physically open the computer's case. Ports can be found on the motherboard and typically include USB ports, audio ports, HDMI ports, and Ethernet ports, among others. These interfaces serve as points of connection for various peripherals such as keyboards, mice, printers, and network cables, allowing for easy expansion and communication with external hardware without internal access.

In contrast, registers pertain to small storage locations within a computer's CPU used for high-speed data processing, making them irrelevant to physical connections. Drivers are software programs that allow the operating system to communicate with hardware devices, but they do not refer to physical connection points. Transceivers are devices that both transmit and receive signals but are typically used in networking contexts and do not serve as general-purpose connection points for external devices like ports do. Understanding these distinctions highlights why ports are the appropriate choice in this context.
