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 physical phenomena on which the device relies (such as spinning platters in a hard drive) will also impose limits; for instance, no spinning platter shipping in 2009 saturates SATA revision 2.0 (3 Gbit/s), so moving from this 3 Gbit/s interface to USB 3.0 at 4.8 Gbit/s for one spinning drive will result in no increase in realized transfer rate.
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 ...
OC-48 is also used as a transmission speed for tributaries from OC-192 nodes in order to optimize card slot utilization where lower speed deployments are used. Slower cards that drop to OC-12, OC-3 or STS-1 speeds are more commonly found on OC-48 terminals, where use of these cards on an OC-192 terminal would not allow for full use of the ...
The word nature of data transfer makes the design of a host bus adapter significantly simpler than that of the precursor HDD controller. CTL-I (Controller Interface) [3] was an 8-bit word serial interface introduced by IBM for its mainframe hard disk drives beginning with the 3333 in 1972. [4]
Each generation of floppy disk drive (FDD) began with a variety of incompatible interfaces but soon evolved into one de facto standard interface for the generations of 8-inch FDDs, 5.25-inch FDDs and 3.5-inch FDDs. [1] For example, before adopting 3.5-inch FDD standards for interface, media and form factor there were drives and media proposed ...
Limitations restrict the effective data transfer rate to about 10 kB/s (80 kbit/s). Control messages are used to configure MOST devices and configure synchronous and asynchronous data transfer. Reference data can also be transferred via the control channel.
