  2. Carrier-sense multiple access with collision detection

    en.wikipedia.org/wiki/Carrier-sense_multiple...

    CSMA/CD is used to improve CSMA performance by terminating transmission as soon as a collision is detected, thus shortening the time required before a retry can be attempted. With the growing popularity of Ethernet switches in the 1990s, IEEE 802.3 deprecated Ethernet repeaters in 2011, [2] making CSMA/CD and half-duplex operation less common ...

    en.wikipedia.org/wiki/Carrier-sense_multiple_access

    CSMA/CD is used to improve CSMA performance by terminating transmission as soon as a collision is detected, thus shortening the time required before a retry can be attempted. CSMA/CD is used by Ethernet. Carrier-sense multiple access with collision avoidance In CSMA/CA collision avoidance is used to improve the performance of CSMA.

  4. Channel access method - Wikipedia

    en.wikipedia.org/wiki/Channel_access_method

    The most common multiple access method is CSMA/CD, which is used in Ethernet. Although today's Ethernet installations use full-duplex connections directly to switches. CSMA/CD is still implemented to achieve compatibility with older repeater hubs.

  5. Carrier-sense multiple access with collision avoidance

    en.wikipedia.org/wiki/Carrier-sense_multiple...

    It is particularly important for wireless networks, where the alternative with collision detection CSMA/CD, is not possible due to wireless transmitters desensing (turning off) their receivers during packet transmission. CSMA/CA is unreliable due to the hidden node problem. [3] [4] CSMA/CA is a protocol that operates in the data link layer.

    The top savings rates, usually offered on online savings accounts, may be similar to or even greater than rates on CD products. Bottom line If you’re looking into CDs or share certificates ...

  7. Network congestion - Wikipedia

    en.wikipedia.org/wiki/Network_congestion

    Networks use congestion control and congestion avoidance techniques to try to avoid collapse. These include: exponential backoff in protocols such as CSMA/CA in 802.11 and the similar CSMA/CD in the original Ethernet, window reduction in TCP, and fair queueing in devices such as routers and network switches.

  8. Contention (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Contention...

    It is for this reason that the shortfall between supplier-claimed access speeds and those experienced by the consumer once signed-up to a contract is particularly bad at just those times when most consumers actually want to use the service. A contention can occur in data communications when no station is designated a master station. In ...

    en.wikipedia.org/wiki/Carrier-sense_multiple...

    In computer networking, carrier-sense multiple access with collision avoidance and resolution using priorities (CSMA/CARP) is a channel access method.CSMA/CARP is similar in nature to the carrier-sense multiple access with collision detection (CSMA/CD) channel access method used in Ethernet networks, but CSMA/CARP provides no detection of network collisions.
