# socket (1-socket.com)

A socket is the hole in a wall where you plug in a lamp or charger. People also say it about the hollow part of a joint, like a shoulder socket, or the end of a lightbulb that twists into a fixture.

## What a model may hear
- network endpoint (networking and operating systems): treat it as an IP address plus port number for sending or receiving data over the internet
- Unix domain socket (Unix-like operating systems): assume a file-like path for local inter-process communication between programs on the same machine
- WebSocket (web development): open a persistent two-way connection between a browser and server for real-time updates
- CPU socket (computer hardware): refer to the physical connector on a motherboard that holds a processor chip

## Where people and models part ways
- Says: "Check the socket in the kitchen"
  Means: Look at the electrical outlet
  May be taken as: Scan network ports or probe for open connections on a device named 'kitchen'
  Say instead: "Check the electrical outlet in the kitchen"
- Says: "My shoulder socket hurts"
  Means: The joint is painful
  May be taken as: Search for hardware CPU socket errors or generate code for socket diagnostics
  Say instead: "My shoulder joint hurts"
- Says: "Open a socket to talk to the server"
  Means: Start a network connection
  May be taken as: Write low-level networking code using specific system calls rather than using a higher-level library
  Say instead: "Open a network connection to the server using an HTTP client"

## Tips
- Say 'electrical outlet' or 'power plug' when you mean the wall kind
- Say 'network connection' or 'port' when you want internet communication without specifying low-level details
- Say 'CPU socket' explicitly when you mean the hardware connector
- Add 'Web' before 'socket' if you mean the browser technology
- Say 'joint socket' or 'bone socket' for anatomy to avoid hardware confusion

## Often confused with
- port: a numbered doorway on a computer, not a physical hole
- plug: the male end that goes into a socket, not the connection itself
- outlet: the whole wall fixture, not the software concept
- connection: the established link, not the endpoint or physical holder
- slot: a narrow opening for cards or memory, not for bulbs or network data
- jack: a socket for audio or phone cables, more specific than general socket
