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。

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。

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。

  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]. (原始内容于2014-01-27). 
  3. ^ 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.
  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.
  5. ^ 5.0 5.1 5.2 5.3 5.4 5.5 5.6 5.7 5.8 5.9 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.

  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.
  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.

  22. ^ ADSL connections will vary in throughput from 64 kbit/s to several Mbit/s depending on configuration. Most are commonly below 2 Mbit/s. Some ADSL and SDSL connections have a higher digital bandwidth than T1 but their rate is not guaranteed, and will drop when the system gets overloaded, whereas the T1 type connections are usually guaranteed and have no contention ratios.
  23. ^ Satellite internet may have a high bandwidth but also has a high latency due to the distance between the modem, satellite and hub. One-way satellite connections exist where all the downstream traffic is handled by satellite and the upstream traffic by land-based connections such as 56K modems and ISDN.
