Telnet predated UDP/IP and originally ran over Network Control Protocol (NCP). [11] The telnet service is best understood in the context of a user with a simple terminal using the local Telnet program (known as the client program) to run a logon session on a remote computer where the user's communications needs are handled by a Telnet server ...
A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
In the case of telnet, each user keystroke is echoed back by the server before the user can see it on the screen. This delay would become very annoying. Setting the socket option TCP_NODELAY overrides the default 200 ms send delay. Application programs use this socket option to force output to be sent after writing a character or line of ...
PuTTY user manual (copy from 2022) PuTTY (/ ˈ p ʌ t i /) [4] is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection.
In computer science and networking in particular, a session is a time-delimited two-way link, a practical (relatively high) layer in the TCP/IP protocol enabling interactive expression and information exchange between two or more communication devices or ends – be they computers, automated systems, or live active users (see login session). A ...
Network Control Program (usually given as NCP) was the name for the software on hosts which implemented the Network Control Protocol of the ARPANET. [ 20 ] [ 5 ] It was almost universally referred to by the acronym, NCP.
Very generally, most of communications can be divided into connection-oriented, and connectionless.Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by application programming interface (API).
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria.
