the amount of information per second used to represent a movie, often expressed in KBps. A single speed CD-ROM movie is usually made at a data rate of 100 KBps, and a double speed CD-ROM about 200 KBps. The data rate of uncompressed NTSC video is about 27 Megabytes per second.

The speed at which data can be transferred. Often described in megabytes per second (MB/sec.). The higher a video file's data rate, the higher quality it will be, but the more system resources (processor speed, hard disk space, and performance) it will take to work with it. Some codecs allow you to specify a maximum data rate for a movie.

A measure of transmission speed. Normally specified in bits per second.

Amount of data that a storage device, such as a hard disk or CD-ROM saves/plays back per second, or the amount of data per second in a video sequence.

The speed at which a channel carries data, measured in bits per second (bps).

The speed at which data is transmitted and received. Usually measured in bits per second (bps).

An attribute assigned to a media file by a compression utility. It is a measure of the amount of digital information transmitted in a given unit of time - usually a second. Thus, a video could be encoded to play back at a rate of 500 kb/s. The data rate set for a file is usually influenced by the limitations of the target delivery medium. CDs, for instance, generally have a maximum transfer rate of 300 kb/s.

The amount of data transferred per second by a computing or storage device. For video compression, the data rate is typically measured in kilobits per second (kbps) or megabits per second (mbps). The higher the data rate, the more data is collected per second, which means the higher the data rate, the better the resulting quality of the digital file. Can also be used to describe audio compression and transfer speed of telecommunications devices.

The same as bit rate or connection speed.

The rate at which data is transferred across the SCSI bus during the data transfer phase. The data rate achieved is dependent upon the bus width (8-bit or 16-bit) and the transfer rate. For example an 8-bit bus operating at 10 Mhz (or Fast) has a data rate of 10 Megabytes per second.

The speed of a data transfer process, normally expressed in bits per second or bytes per second.

the rate at which circuits or other devices operate when handling digital information

The speed of a data communications channel, measured in bits per second.

The speed of a data transfer process, usually expressed in kilobytes (thousands of bytes) per second. See also bit rate .

Data transmission speed measured in bits per second (bps).

The speed in bits or bytes per second at which a data steam is transmitted. This can be net, i.e. actual rate of the data stream, or gross, the overall rate of the transmitted signal including transport overhead such as modulation, encryption and error correction coding. In the digital domain, data rate is sometimes used interchangeably with bandwidth.

The amount of data that a particular connection can sustain over time. Usually measured in bytes/second.

The speed of data transfer within a computer or between a peripheral device and a computer.

The maximum number of bits of information which can be transmitted per second. Typically expressed as megabits per second (Mb/s).

The amount of data which is transferred in one second. In a video file, this means the amount of data the file must transfer to be viewed at normal speed.

The amount of information used to represent the video and audio. Confusingly, it is sometimes represented in kilobits per second (kBs) and sometimes in kilobytes per second (kbs).

Not all bits carry user information. Each group (packet) of bits contains headers, trailers, echo control, destination information, and other data required by the transmission protocol. It is important to understand the difference between bit rate and data rate, since the overhead information may consume more than 40% of the total transmission. This difference is common to many such data systems, including Ethernet.

The speed of the data transmission, measured in bps (bits per second) or Mbps.

The amount of information per second used to represent a movie expressed in KBps. A double speed CD-ROM movie is usually made at a data rate of 167 KBps. The data rate of uncompressed NTSC video is about 27 Megabytes per second. One thing to note is that if the data rate is faster than your Internet connection or CD-ROM, then palyback will be choppy.

The rate or speed at which data is transmitted, usually stated in bits per second or Baud.

The volume of data measured over time; the rate at which digital information can be conveyed. Usually expressed as bits per second with notations of kbps (thousand/sec), Mbps (million/sec), and Gbps (billion/sec). Digital audio date rate is generally computed as the number of samples per second times the bit size of the sample. For example, the data rate of uncompressed 16-bit, 48-kHz, two-channel audio is 1536 kbps. Digital video bit rate is generally computed as the number of bits per pixel times the number of pixels per line times the number of lines per frame times the number of frames per second. For example, the data rate of a DVD movie before compression is usually 12 x 720 x 480 x 24 = 99.5 Mbps. Compression reduces the data rate. Digital data rate is sometimes inaccurately equated with bandwidth.

Pre-determined rates set in the 802.11 standard that provide for systematic speed decreases to maintain a connection as the client moves farther away from the access point. The OFDM data rates include: 54, 48, 36, 24, 18, 12, 11, 9, 6, 5.5, 2 and 1. This is not the actual speed at which data is sent (called throughput), because of built-in redundancy, error correction, and protocol overhead. (See also: Throughput)

Speed that information moves from one item to another. This is usually in the form of bits.

Often conflated with bit rate, data rate refers to the actual throughput or aggregate rate over time at which the essence is being delivered.

The amount of information transmitted per unit time.

The amount of data a hard disk, CD-ROM or other device is capable of saving or playing per second and/or the amount of data-per-second in a video sequence.

The speed, measured in bits per second, that a particular network (or other application) transmits data.

The number of information bits per second which are broadcast.

A measurement of bandwidth. Higher data rate equals more bandwidth. In general, the higher the data rate, the higher the quality of video and/or audio.

The speed of the data stored on a type of media, usually expressed in bits per second or bytes per second

The rate at which serial information is sent. If there are no idle gaps between frames the data rate is equal to the baud rate.

The speed with which data can be transmitted from one device to another. Data rates are often measured in bits or bytes per second. These are usually abbreviated as Kbps or Mbps.

Data rates are usually dictated by the system - how much data must be transferred and how often does the transfer need to take place. Lower data rates allow the radio module to have better receive sensitivity and thus more range. Higher data rates allow the communication to take place in less time, potentially using less power to transmit.

Also known as bit rate or video bandwidth. The amount of information required to represent digital video or audio, often measured in bits per second (bps), kilobits per second (kpbs) or megabits per second (mbps). As screensize, picture quality, sound quality and fluidity of motion increase, so does bandwidth. If the bandwidth a movie requires is greater than your connection to the Internet, then you will have to download the movie before viewing it.

The speed at which data is read, measured in kilobytes per second (kbps).

The number of bits of information in a transmission system, expressed in bits per second (b/s or bps), and which may or may not be equal to the signal or baud rate.

The rate at which bits of information are transmitted per second.
