장비 대역폭 목록 – 1.Computer buses
This is a list of device bandwidths: the channel capacity (or, more informally, bandwidth) of some computer devices employing methods of data transport is listed by bit/s, kilobit/s (kbit/s), megabit/s (Mbit/s), or gigabit/s (Gbit/s) as appropriate and also MB/s or megabytes per second. They are listed in order from lowest bandwidth to highest.
Whether to use bit/s or byte/s (B/s) is often a matter of convention. The most commonly cited measurement is bolded. In general, parallel interfaces are quoted in byte/s (B/s), serial in bit/s. On devices like modems, bytes may be more than 8 bits long because they may be individually padded out with additional start and stop bits; the figures below will reflect this. Where channels use line codes, such as Ethernet, Serial ATA and PCI Express, quoted speeds are for the decoded signal.
Many of these figures are theoretical maxima, and various real-world considerations will generally keep the actual effective throughput much lower. The actual throughput achievable on Ethernet networks, for example (especially when heavily loaded or when running over substandard media), is debatable. The figures are also simplex speeds, which may conflict with the duplex speeds vendors sometimes use in promotional materials.
All of the figures listed here are true metric quantities and use metric binary prefixes (1 kilobit, for example, is 1000 bits, not 1024 bits). Similarly, kB, MB, GB mean kilobytes, megabytes, gigabytes, not kibibytes, mebibytes, gibibytes.
