Bit rateIn telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed as bits per second (symbol: bit/s), often with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). The non-standard abbreviation bps is often used: 1 Mbps is 1 Mbit/s, that is, one million bits per second.
Channel capacityInformation-theoretical limit on transmission rate in a communication channelChannel capacity, in electrical engineering, computer science, and information theory, is the theoretical maximum rate at which information can be reliably transmitted over a communication channel.Bandwidth (computing)In computing, bandwidth is the maximum rate of data transfer across a given path. Bandwidth may be characterized as network bandwidth, data bandwidth, or digital bandwidth.Flow control (data)In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred. Flow control mechanisms can be classified by whether or not the receiving node sends feedback to the sending node.
Packet lossPacket loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, or network congestion. Packet loss is measured as a percentage of packets lost with respect to packets sent. The Transmission Control Protocol (TCP) detects packet loss and performs retransmissions to ensure reliable messaging.Communication channelA communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. A channel is used for information transfer of, for example, a digital bit stream, from one or several senders to one or several receivers.
GoodputIn computer networks, goodput (a portmanteau of good and throughput) is the application-level throughput of a communication. In other words, goodput is the number of useful information bits delivered by the network to a certain destination per unit of time. The amount of data considered excludes protocol overhead bits as well as retransmitted data packets.
Time-division multiplexingTime-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 according to agreed rules, e.g. with each transmitter working in turn. It can be used when the bit rate of the transmission medium exceeds that of the signal to be transmitted.
EthernetEthernet ( ) is a family of wired computer networking standards designed for (but not limited to) local area networks (LAN), access networks, and metropolitan area networks (MAN). It was commercially introduced in 1980 and first standardized in 1983 as ECMA-82 and shortly after as IEEE 802.3. It is an example of an open standard.
Packet radioPacket radio is the application of packet switching techniques to digital radio communications. Packet radio is frequently used by amateur radio operators. The AX.25 (Amateur X.25) protocol was derived from the X.25 protocol and adapted for amateur radio use. Every AX.25 packet includes the sender's amateur radio callsign, which satisfies the United States Federal Communications Commission (FCC) requirements for amateur radio station identification.Overhead (computing)In computing, overhead is the consumption of computing resources for aspects that are not directly related to achieving a desired goal. Overhead is required for more general processing and impacts achieving a more focused goal. Overhead manifests as aspects such as slower processing, less memory, less storage capacity, less network bandwidth, and longer latency. Overhead can impact software design with regard to structure, error correction, and feature inclusion.Node (computer networking)In networking, a node (Latin: nodus, 'knot') is either a redistribution point or a communication endpoint within telecommunication networks or computer networks. A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel.
