ध्यान रहे कि यहाँ दिये हुए आंकड़े अधिकतम मान प्रदर्शित कर रहे हैं। वास्त्विक स्थितियों में (जैसे वैद्युत शोर (न्वायज) की स्थिति में) इनसे कम दर पर ही आंकडा-विनिमय हो पाता है।[2]

Note: 802.11 networks are half-duplex; all stations share the medium. In access point mode, all traffic has to pass through the AP (Access Point). Two stations on the same AP which are communicating with each other will have all traffic pass the medium twice: once sent by the sender to the AP, then from AP to receiver, thus approximately halving the effective bandwidth.

NOTE: Dual channel bandwidths are theoretical maximums and do not always reflect real world performance. In many cases, performance may be closer to single channel operation (half the bandwidth).

  1. TTY, Baudot code कोड का प्रयोग करती है, न कि आस्की (ASCII). यह ८ बिट प्रति अक्षर के बजाय ५ बिट प्रति अक्षर का होता है। इसके अलावा १ आरम्भ बिट (start bit) तथा 1.5 समाप्ति बिट (stop bits) प्रयुक्त होते हैं। (इस प्रकार कुल 7.5 बिट प्रति अक्षर).

  3. 300 baud modems operating at 30 characters per second, were often described as "reading speed" since the characters scrolled across the screen at the same rate as most people can read. All modems are assumed to be in serial operation with 1 start bit, 8 data bits, no parity, and 1 stop bit (2 stop bits for 110-baud modems). Therefore, a total of 10 bits (11 bits for 110-baud modems) are needed to transmit each 8-bit byte. The "bytes" column reflects the net data transfer rate after the protocol overhead has been removed.
  4. 56K modems: V.90 and V.92 capacity can only be achieved when the upstream (service provider) end of the connection is digital. In addition, certain telecommunications administrations limit the signal strength the modem can transmit onto the telecommunications circuit, which in turn limits the actual maximum data rate to less than the theoretical maximum. In the USA, this limited the possible downstream maximum to 53.3 kbit/s.
  5. 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 2 "B" channels and one "D" channel. Each B channel provides 64 kbit/s bandwidth and the 'D' channel carries signalling (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 1 D-channel; in T1 regions the PRI carries 23 B-channels and 1 D-channel. The D-channel has different bandwidth on the two interfaces.
  6. 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 bandwidth than T1 but their bandwidth is not guaranteed, and will drop when the system gets overloaded, whereas the T1 type connections are usually guaranteed and have no contention ratios.

  8. DOCSIS 2.0 Archived 2009-09-04 at the वेबैक मशीन specifications provide increased upstream throughput for symmetric services.

  11. The Zorro II bus use 4 clocks per 16-Bit of data transferred. See the Zorro III technical specification Archived 2012-07-16 at the वेबैक मशीन for more information.
  12. David Hayine, designer of the Zorro III bus, claims in this Archived 2012-11-07 at the वेबैक मशीन posting that the theoretical max of the Zorro III bus can be derived by the timing information given in ‘’chapter 5’’ of the Zorro III technical specification Archived 2012-07-16 at the वेबैक मशीन.
  13. David Hayine, designer of the Zorro III bus, claims in this Archived 2012-11-07 at the वेबैक मशीन posting that Zorro III is an asynchronous bus and with that does not have a classical MHz rating. A maximum theoretical MHz value may be derived by examining timing constraints detailed in the Zorro III technical specification Archived 2012-07-16 at the वेबैक मशीन, which should yield about 37.5 MHz. No existing implementation performs to this level.
  14. David Hayine, designer of the Zorro III bus, claims in this Archived 2012-11-07 at the वेबैक मशीन posting that Zorro III has a max burst rate of 150 MB/s.
  15. Note that PCI Express lanes use an 8B/10B encoding scheme.
  16. InfiniBand uses an 8B/10B encoding scheme.
  17. PCIe 2.0 effectively doubles the bus standard's bandwidth from 2.5 Gbit/s to 5 Gbit/s
  18. Fibre Channel 1GFC, 2GFC, 4GFC use an 8B/10B encoding scheme. Fibre Channel 10GFC, which uses a 64B/66B encoding scheme, is not compatible with 1GFC, 2GFC and 4GFC, and is used only to interconnect switches.
  19. SATA and SAS use an 8B/10B encoding scheme.
  20. FireWire (IEEE 1394b) uses an 8B/10B coding scheme.

  22. Actual frame relay connections will vary in throughput from 8 kbit/s to 45 Mbit/s depending on configuration. Most are commonly below 2 Mbit/s.
  23. 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 & SDSL connections have a higher bandwidth than T1 but their bandwidth is not guaranteed, and will drop when the system gets overloaded where as the T1 type connections are usually guaranteed and have no contention ratios.
  24. 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.
