What type of port allows for easy installation and daisy-chaining of up to 127 devices?

The correct answer is USB Port, which is designed for easy installation and supports daisy-chaining of multiple devices, allowing up to 127 devices to be connected through a single port. USB (Universal Serial Bus) technology simplifies the process of connecting peripherals such as keyboards, mice, printers, and external drives without the need for complex configurations. The USB standard includes features for power supply to devices and allows for hot swapping, which means devices can be connected or disconnected while the computer is running.

In contrast, other options do not provide the same level of flexibility or functionality. For example, serial ports typically support only one device at a time and require extensive setup for additional connections. Parallel ports also predominantly connect a single device at a time and are largely outdated in favor of USB. Ethernet ports facilitate networking and communication between computers but are not designed for daisy-chaining devices like peripheral connections in the USB standard.
