電腦裝置頻寬列表

這是一個電腦裝置頻寬列表，列出一般電腦裝置的信道容量，即轉輸數據的（理論上）最高轉送速度，以千位元每秒（kbit/s/kbps）、百萬位元每秒（Mbit/s/Mbps）、十億位元每秒（Gbit/s/Gbps）或兆位元每秒（Tbit/s/Tbps）表示。以下每按裝置的功能分組，按信道容量由小至大排列。

為方便非技術人員比較頻寬的大小，每類頻寬都有一個公用單位，例如電話頻寬為 1.2 kbit/s，其中一種舊式數據機的頻寬為 56 kbit/s。使用位元每秒（bit/sec）或位元組每秒（Byte/sec）則視乎一般人慣用哪一個。慣用的單位在列表中以粗體表示。一般來說，并行通訊介面用位元每秒（bit/sec），串行通訊則用位元組每秒（Byte/sec）。至於類似數據機的裝置中，基於用作分隔每一位元組（Byte）的 和 Stop bit，一位元組可能含有超過八個位元（bit），以下的列表已經有考慮這一點。而如果有像乙太網路、SATA，與PCI Express等使用到調變技術的通道，列出的頻寬速度則是表示調變後的訊號速度。

很多以下的數據只是例出理論上最快的傳送速度，有很多的因素都會令傳送速度減低。同時以下數據只表示半雙工傳送速度，可能與生產商聲稱的全雙工度有所出入。


附註：以下所有數據單位以公制（以10為基數）表示：
 1 Bytes = 8 bits
 1 kbit = 1,000 bits
 1 kB = 1,000 Bytes
 1 MB = 1,000,000 Bytes
 1 GB = 1,000,000,000 Bytes
 1 TB = 1,000,000,000,000 Bytes
 1 PB = 1,000,000,000,000,000 Bytes
 1 EB = 1,000,000,000,000,000,000 Bytes
 1 ZB = 1,000,000,000,000,000,000,000 Bytes
 1 YB = 1,000,000,000,000,000,000,000,000 Bytes
如此類推。

 名稱  最高速率(位元)  最高速率(位元組/s) 推出年分 摩斯電碼  Morse can transport 26 alphabetic, 10 numeric and one interword gap plaintext symbols. Transmitting 37 different symbols requires 5.21 bits of information (25.21=37). A skilled operator encoding the benchmark "PARIS" plus an interword gap (equal to 31.26 bits) at 40 wpm is operating at an equivalence of 20.84 bit/s.  ()WPM, or Words Per Minute, is the number of times the word "PARIS" is transferred per minute. Strictly speaking the code is quinary, accounting inter-element, inter-letter, and inter-word gaps, yielding 50 binary elements (bits) per one word. Counting characters, including inter-word gaps, gives six characters per word or 240 characters per minute, and finally four characters per second. 1844 110 鮑率數據機 (Bell 101)   (~10 cps)All modems are wrongly assumed to be in serial operation with 1 start bit, 8 data bits, no parity, and 1 stop bit (2 stop bits for 110-鮑率 modems). Therefore, currently modems are wrongly calculated with transmission of 10 bits per 8-bit byte (11 bits for 110-鮑率 modems). Although the serial port is nearly always used to connect a modem and has equivalent data rates, the protocols, modulations and error correction differ completely. 1959 300 數據機 (300 鮑率; Bell 103 or V.21)   (~30 cps) 1962 1200 數據機 (600 鮑率; Bell 212A or V.22)   (~120 cps) 1976 1200/75 數據機  (600 鮑率; V.23) 1.2/0.075kbit/s 0.12/0.0075kB/s (~120 cps) 1988 2400 數據機 (600 鮑率; V.22bis)   1988 4800 數據機 (1600 鮑率; V.27ter)   1988 9600 數據機 (2400 鮑率; V.32)   1989 14.4 數據機  (2400 鮑率; V.32bis)   1991 28.8 數據機  (3200 鮑率; V.34-1994)   1994 33.6 數據機  (3429 鮑率; V.34-1996/98)   1996 56k 數據機  (8000/3429 鮑率; V.90) 56.0/33.6kbit/s56K modems: V.90 and V.92 have just 5% overhead for the protocol signalling.

A basic rate interface (BRI) provides two "B" channels and one "D" channel. Each B channel provides 64 kBit/s bandwidth and the "D" channel carries signaling (call setup) information. B channels can be bonded to provide a 128 kbit/s data rate. Primary rate interfaces (PRI) vary depending on whether the region uses E1 (Europe, world) or T1 (North America) bearers. In E1 regions, the PRI carries 30 B-channels and one D-channel; in T1 regions the PRI carries 23 B-channels and one D-channel. The D-channel has different bandwidth on the two interfaces. 8/16kB/s 1986 IDSL (dual ISDN + 16 kbit/s data channels)   2000

由於檔頭與其他因素，承載資料的吞吐量是小於實際資料傳輸量，所以不要將速度與實際資料傳輸率混為一談。「通常實際速度會因為當前流量而降至 1/3-2/3 的速度。而且，如果發生任何傳輸問題而使得實體層發生重新傳送的狀況時，吞吐量也會因而受影響。」
