Computer Port Question & Answers December 28, 2022 By WatElectronics This article lists 50 Computer Port MCQs for engineering students. All the Computer Port Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, or interviews, or professionals who would like to brush up on the fundamentals of Computer Port. A computer port is a hardware slot used for interfacing external peripheral devices for communication and device operation purposes. These peripheral devices include a mouse, printer, cables, etc. Each of these computer ports is assigned a unique number which communicates based on the protocol's port numbering. Computer ports are of multiple types namely, serial port/ D-Subminiature, display port, DVI port, Ethernet, etc. In computer networks, a port identifies connection endpoints and route data to specific services. The speed of data transfer in a serial port is slower compared to the parallel port. The Ethernet port facilitates network and high-speed Internet connectivity. Although there are 7 layers in an OSI model each of the networking protocols operates on specific layers. For example, HTTP is the port number 80 on a computer that operates on the transport layer The advantage of these computer ports is each of the ports is specifically designed for a specific purpose. 1).
