The maximum goodput (for example, the file transfer rate) may be even lower due to higher layer protocol overhead and data packet retransmissions caused by line noise or interference such as crosstalk, or lost packets in congested intermediate network nodes. Most of the listed rates are theoretical maximum throughput measures in practice, the actual effective throughput is almost inevitably lower in proportion to the load from other devices ( network/ bus contention), physical or temporal distances, and other overhead in data link layer protocols etc. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.įactors limiting actual performance, criteria for real decisions Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure.
The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications networks.
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. JSTOR ( March 2011) ( Learn how and when to remove this template message).
