Port
A single PC can simultaneously establish multiple connections and provide
multiple services for other PCs. Ports are used to differentiate these connec-
tions from parallel connections. Due to a common agreement, PCs usually
provide their services on ports 1 to 1023. Outgoing connections are usually
established starting at port 1024. Most services that use the standard port
numbers (for example, web browsers use port 80).
