Asynchronous serial communication is a form of serial communication in which the communicating endpoints' interfaces are not continuously synchronized by a common clock signal.
A computer network, or data network, is a digital telecommunications network which allows nodes to share resources.
The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking.
Data transmission (also data communication or digital communications) is the transfer of data (a digital bitstream or a digitized analog signal) over a point-to-point or point-to-multipoint communication channel.
A datagram is a basic transfer unit associated with a packet-switched network.
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions.
In computer networking, encapsulation is a method of designing modular communication protocols in which logically separate functions in the network are abstracted from their underlying structures by inclusion or information hiding within higher level objects.
A data unit on an Ethernet link transports an Ethernet frame as its payload.
In computer networking, a Fibre Channel frame is the frame of the Fibre Channel protocol.
A frame check sequence (FCS) refers to the extra error-detecting code added to a frame in a communications protocol.
In telecommunication, frame synchronization or framing is the process by which, while receiving a stream of framed data, incoming frame alignment signals (i.e., a distinctive bit sequences or syncwords) are identified (that is, distinguished from data bits), permitting the data bits within the frame to be extracted for decoding or retransmission.
The Internet Engineering Task Force (IETF) develops and promotes voluntary Internet standards, in particular the standards that comprise the Internet protocol suite (TCP/IP).
In computer networking, a minimal pause may be required between network packets or network frames.
In computer networking, jumbo frames or jumbos are Ethernet frames with more than 1500 bytes of payload, the limit set by the IEEE 802.3 standard.
The ITU-T V-Series Recommendations on Data communication over the telephone network specify the protocols that govern approved modem communication standards and interfaces.
In telecommunications and computer networks, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
A network packet is a formatted unit of data carried by a packet-switched network.
The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology.
In data transmission and telecommunication, overhead bits are nondata bits necessary for transmission (usually as part of headers, checksums, and such).
Packet switching is a method of grouping data which is transmitted over a digital network into packets which are made of a header and a payload.
In computing and telecommunications, the payload is the part of transmitted data that is the actual intended message.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communications protocol used to establish a direct connection between two nodes.
In telecommunications, a protocol data unit (PDU) is information that is transmitted as a single unit among peer entities of a computer network.
Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or other electromagnetic systems.
Time-division multiple access (TDMA) is a channel access method for shared-medium networks.
Time-division multiplexing (TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern.
2G (or 2-G) is short for second-generation cellular technology.
3G, short for third generation, is the third generation of wireless mobile telecommunications technology.
