Sockets in C

• socket = low level endpoint used for processing information across a network
• common network protocols like HTTP and FTP rely on sockets underneath to make connections

Client Socket Workflow

• socket() => connect() => recv()
• client socket is created with a socket()
• connected to an address with connect() call
• retrive data with recv() call

Server Socket Workflow

• create socket with a socket() call
• bind socket to an IP and port
• listen for connections
• accept a connection and call send() or recv() function
