Study Notes
Sockets and Networking
- A socket identifies an endpoint in a network, enabling a single computer to serve multiple clients and types of information simultaneously.
- A port is a numbered socket on a particular machine, allowing a server to accept multiple clients connected to the same port number.
Protocols
- Internet Protocol (IP): a low-level routing protocol that breaks data into packets and sends them to an address across a network, without guaranteeing delivery.
- Transmission Control Protocol (TCP): a higher-level protocol that manages to robustly string together packets, sorting and retransmitting them as necessary to reliably transmit data.
- User Datagram Protocol (UDP): a protocol that sits next to TCP, supporting fast, connectionless, and unreliable transport of packets.
- Hyper Text Transfer Protocol (HTTP): the protocol used by web browsers and servers to transfer hyper-text pages and images.
