For example, a single link PCIe 3.0 interface has an 8 Gbit/s transfer rate, yet its usable bandwidth is only about 7.88 Gbit/s. z Uses 8b/10b encoding , meaning that 20% of each transfer is used by the interface instead of carrying data from between the hardware components at each end of the interface.
IEEE 1394 is a serial bus architecture for high-speed data transfer, serial meaning that information is transferred one bit at a time. Parallel buses utilize a number of different physical connections, and as such are usually more costly and typically heavier. [6] IEEE 1394 fully supports both isochronous and asynchronous applications.
Profibus (usually styled as PROFIBUS, as a portmanteau for Process Field Bus) is a standard for fieldbus communication in automation technology and was first promoted in 1989 by BMBF (German department of education and research) and then used by Siemens. [1] It should not be confused with the Profinet standard for Industrial Ethernet. Profibus ...
The ISQ symbols for the bit and byte are bit and B, respectively.In the context of data-rate units, one byte consists of 8 bits, and is synonymous with the unit octet.The abbreviation bps is often used to mean bit/s, so that when a 1 Mbps connection is advertised, it usually means that the maximum achievable bandwidth is 1 Mbit/s (one million bits per second), which is 0.125 MB/s (megabyte per ...
To reduce the number of pins in a package, many ICs use a serial bus to transfer data when speed is not important. Some examples of such low-cost lower-speed serial buses include RS-232, DALI, SPI, CAN bus, I²C, UNI/O, and 1-Wire. Higher-speed serial buses include USB, SATA and PCI Express.
Additionally, USB ports are color-coded according to the specification and data transfer speed, e.g. USB 1.x and 2.x ports are usually white or black, and USB 3.0 ones are blue. SuperSpeed+ connectors are teal in color. [2] FireWire ports used with video equipment (among other devices) can be either 4-pin or 6-pin. The two extra conductors in ...
FireWire cameras use the IEEE 1394 bus standard for the transmission of audio, video and control data. FireWire is Apple Computer 's trademark for the IEEE 1394 standard. FireWire cameras are available in the form of photo cameras and video cameras , which provide image and audio data .
Serial Front Panel Data Port [1] (Serial FPDP or SFPDP) is a high speed low latency data streaming serial communication protocol. It currently supports several distinct speeds: [ 2 ] 1.0625 Gbit / s
