Definition
Meaning
A physical socket on a computer or electronic device designed to connect peripherals via a Universal Serial Bus (USB) cable for data transfer and power supply.
The term can refer to the physical hardware interface, the technical specification (e.g., USB 3.0 port), and by extension, the point of connectivity or access for peripheral devices. In metaphorical use, it can signify a standardized point of connection or integration.

Memory Aids
Mnemonic
Think of a USB port as a 'Universal Socket for Bus' – a common entry point where the data 'bus' meets your device.
Conceptual Metaphor
A DIGITAL HARBOUR or GATEWAY. It is a point of entry/exit for the 'flow' of information and power, much like a seaport is for goods.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'port' as 'порт' in the maritime sense only; in computing, it's 'порт' (e.g., USB-порт). 'USB' is universally used as a loanword.
- Do not confuse with 'порт' meaning 'harbour'. The computing term is a direct semantic borrowing.
Common Mistakes
- Saying 'USB portal' (incorrect).
- Using 'USB port' to refer to the cable end (that is the 'USB connector' or 'plug').
- Misidentifying other ports (e.g., HDMI, Thunderbolt) as USB ports.

FAQ
Frequently Asked Questions
Not exactly. 'USB port' is a general term. 'USB-C' refers to a specific, reversible oval-shaped port connector that can support various USB standards (like USB 3.2 or USB4). All USB-C ports are a type of USB port, but not all USB ports are USB-C (e.g., USB-A is older and rectangular).
Yes, all standard USB ports provide a small amount of power (5V) to connected devices, which is enough for items like mice, keyboards, and phone charging. Special specifications like USB Power Delivery (USB-PD) allow for much higher power delivery through compatible ports (like USB-C) for charging laptops.
USB stands for Universal Serial Bus. It is an industry standard that establishes specifications for cables, connectors, and protocols for connection, communication, and power supply between computers and electronic devices.
Common reasons include physical damage (bent pins), dirt/debris in the port, outdated or corrupted device drivers in the operating system, a faulty connected device, or insufficient power from the port for the device's needs. Trying a different port or cable is a common first step in troubleshooting.
