Thus, encoding/decoding is the translation needed for a message to be easily understood. When you decode a message, you extract the meaning of that message in ways to simplify it. Decoding has both verbal and non-verbal forms of communication: Decoding behavior without using words, such as displays of non-verbal communication.
ASN.1 specifies several TLV-based encoding rules (BER, DER), as well as non-TLV based ones (PER, XER). CSN.1 describes encoding rules using non-TLV semantics. More recently, [when?] XML has been used to implement messaging between different nodes in a network. These messages are typically prefixed with line-based text commands, such as with BEEP.
The physical layer is responsible for physical transmission of the data, link encapsulation allows local area networking, IP provides global addressing of individual computers, and TCP selects the process or application (i.e., the TCP or UDP port) that specifies the service such as a Web or TFTP server.

The term encoding-decoding model is used for any model that includes the phases of encoding and decoding in its description of communication. Such models stress that to send information, a code is necessary. A code is a sign system used to express ideas and interpret messages. Encoding-decoding models are sometimes contrasted with inferential ...
H.323 is defined as a binary protocol, which allows for efficient message processing in network elements. The syntax of the protocol is defined in ASN.1 and uses the Packed Encoding Rules (PER) form of message encoding for efficient message encoding on the wire. Below is an overview of the various communication flows in H.323 systems.
A network is a medium to which many nodes can be connected, on which every node has an address and which permits nodes connected to it to transfer messages to other nodes connected to it by merely providing the content of a message and the address of the destination node and letting the network find the way to deliver the message to the ...
January 2008) (Learn how and when to remove this message) In telecommunications , signaling is the use of signals for controlling communications . This may constitute an information exchange concerning the establishment and control of a telecommunication circuit and the management of the network.
The Serial Line Internet Protocol (SLIP) [1] [2] is an encapsulation of the Internet Protocol [a] designed to work over serial ports and router connections. It is documented in RFC 1055.
