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。

區域網路

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。」^[25]

無線網路

802.11 都是半雙工形式的網路。在存取點模式，所有的承載資料都要經過 AP。當兩台電腦要用同一台 AP 相互通訊時，所有的承載資料都要二次傳輸：第一次從發出者到 AP，再來從 AP 發送到接收者，這將使實際頻寬折半。

記憶體匯流排

雙通道頻寬是理論上能夠達到的最大頻寬值，並不表示實際操作會有相等的效能提升。在許多方面，雙通道（2 倍頻寬）的效能與單通道的效能相近。

^ TTY uses a Baudot code, not ASCII. This uses 5 bits per character instead of 8, plus one start and approx. 1.5 stop bits (7.5 total bits per character sent).
^ Data communication over the telephone network. [2008-02-06]. （原始内容存档于2014-01-27）.
^ Morse can transport 26 alphabetic, 10 numeric and one interword gap plaintext symbols. Transmitting 37 different symbols requires 5.21 bits of information (2^5.21=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.
^ ^5.00 ^5.01 ^5.02 ^5.03 ^5.04 ^5.05 ^5.06 ^5.07 ^5.08 ^5.09 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.

^ Note that effective aggregate bandwidth for an ISDN installation is typically higher than the rates shown for a single channel due to the use of multiple channels. 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.

Interconnection Speeds Compared （页面存档备份，存于互联网档案馆）
Need for Speed: Theoretical Bandwidth Comparison （页面存档备份，存于互联网档案馆） — Contains a graph illustrating bandwidth speeds

[1] TTY uses a Baudot code, not ASCII. This uses 5 bits per character instead of 8, plus one start and approx. 1.5 stop bits (7.5 total bits per character sent).

[2] Data communication over the telephone network. [2008-02-06]. （原始内容存档于2014-01-27）.

[morse_bps-3] Morse can transport 26 alphabetic, 10 numeric and one interword gap plaintext symbols. Transmitting 37 different symbols requires 5.21 bits of information (2^5.21=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.

[morse_wpm-4] 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.

[modem-5] 5.00 ^5.01 ^5.02 ^5.03 ^5.04 ^5.05 ^5.06 ^5.07 ^5.08 ^5.09 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.

[56k-8] 8.0 ^8.1 ^8.2 56K modems: V.90 and V.92 have just 5% overhead for the protocol signalling. The maximum capacity can only be achieved when the upstream (service provider) end of the connection is digital, i.e. a DS0 channel.

[isdn-9] Note that effective aggregate bandwidth for an ISDN installation is typically higher than the rates shown for a single channel due to the use of multiple channels. 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.
