<ref><ref></ref></ref>== Connection-oriented and connectionless communications ==

Very generally, most of communications can be divided into connection-oriented, and connectionless. Whether a communication is a connection-oriented, or connectionless, is defined by the communication protocol, and not by [[Application_programming_interface|API]]. Examples of the connection-oriented protocols include TCP and SPX, and examples of connectionless protocols include UDP, "raw IP", and IPX

Very generally, most of communications can be divided into [[Connection-oriented_communication|connection-oriented]], and [[Connectionless_communication|connectionless]]. Whether a communication is a connection-oriented, or connectionless, is defined by the [[Communications_protocol|communication protocol]], and not by {{nowr|[[Application_programming_interface|APIapplication programming interface]] (API)}}. Examples of the connection-oriented protocols include {{nowr|[[Transmission Control Protocol]] (TCP)}} and {{nowr|[[Sequenced Packet Exchange]] (SPX)}}, and examples of connectionless protocols include {{nowr|[[User Datagram Protocol]] (UDP)}}, "raw IP", and {{nowr|[[Internetwork Packet Exchange]] (IPX)}}.

== Clients and servers ==

{{main|client–server model}}

For connection-oriented communications, communication parties usually have different roles. One party is usually waiting for incoming connections; this party is usually referred to as "[[Server_(computing)|server]]". Another party is the one which initiates connection; this party is usually referred to as "[[Client_(computing)|client]]".

For connectionless communications, one party ("server") is usually waiting for an incoming packet, and another party ("client") is usually understood as the one which sends an unsolicited [[Network_packet|packet]] to "server".

== Popular protocols and APIs ==

Network programming traditionally covers different layers of [[OSI_model|OSI/ISO model]] (most of application-level programming belongs to L4 and up). The table below contains some examples of popular protocols belonging to different OSI/ISO layers, and popular APIs for them.
