Computer Hardware
Port
Definition
In computer hardware, a port serves as an interface between the computer and other computers or peripheral devices. Physically, a port is a specialized outlet on a piece of equipment to which a plug or cable connects.
Why It Matters
Ports are the physical points of connection that allow a computer to be expanded and connected to other devices, forming the gateway for input and output.
Contextual Example
A laptop typically has several ports, such as USB ports for peripherals, an HDMI or DisplayPort for connecting a monitor, and an audio jack for headphones.
Common Misunderstandings
- This "hardware port" is different from a "network port" (or "software port"), which is a virtual point for network communication.
- Common hardware ports include USB, HDMI, DisplayPort, Ethernet, and Thunderbolt.
