  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 ...

    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. 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 average national CD account rate is 1.83% for a one-year term. Even with some high-yield CDs earning around 4.50% APY, it doesn’t come close to what you could earn over the long-term in an ...

    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.

  7. Channel access method - Wikipedia

    en.wikipedia.org/wiki/Channel_access_method

    The code-division multiple access (CDMA) scheme is based on spread spectrum, meaning that a wider radio channel bandwidth is used than the data rate of individual bit streams requires, and several message signals are transferred simultaneously over the same carrier frequency, utilizing different spreading codes.

  8. What to do when your CD matures in a falling-rate environment

    When a CD matures, you face a decision: reinvest the principal (and possibly interest) into another CD, find a new investment, or simply hold onto the cash. Here are some of your options. Keep the ...

  9. Time-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Time-division_multiple_access

    It allows several users to share the same frequency channel by dividing the signal into different time slots. [1] The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel ...
