What all ethernet networks independent of their speed or frame type and use an access called?
csma
Which is a drawback of the CSMA CD access method?
Collisions can decrease network performance.
What is the difference between csma CD and csma ca - 42k?
*** In CSMA/CD it detects that a collision take place and resend the frame that was send. On a wirless network losing bandwidth along with time to detect that a collision took place was not acceptable , so CSMA/CA was utilized. ** CSMA/CD can achieve above 70% efficiency under heavy loads compared to CSMA/CA that can only achieve up to 30% efficiency under heavy loads. CSMA/CA network: A network in which the medium access control protocol requires carrier sense and where a station always starts transmission by sending a jam signal; if there is no collision with jam signals from other stations, it begins sending data; otherwise, it stops transmission and then tries again later. CSMA/CD network: A bus network in which the medium access control protocol requires carrier sense and in which exception conditions caused by collision are resolved by retransmission
What is the purpose of the Frame Check Sequence field in a Data Link frame trailer?
The purpose of the FCS field is to transmit the extra checksum characters added to a frame in "xyz" protocol for error detection. The most popular algorithm I've used is the CRC (cyclic redundancy check) employed in things like ethernet or PPP on a routed network. Keep in mind that ethernet defines that the errored frame should be discarded, but ethernet takes no action to cause the frame to be retransmitted. Typically most tech's see it as unnecessary overhead and opt to rely on CSMA\CD or CSMA\CA if the route is not deemed to carry time sensitive data. Hope that clears things up a bit.
Which of these options are characteristics of the Ethernet data transmission standard?
Data transmissions is via frames, each having a single MAC address. The CSMA/CD access method is used to detect collisions.
What is the function of CSMA CA on a wireless Ethernet network?
To prevent collisions.
What is the function of CSMA on a wireless Ethernet network?
It is prevent all connected network cards sending at the same time.
Which access method is used by Ethernet?
CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
Which Ethernet standards supports csma CD?
10BaseT
What is one operational characteristic of a shared-media Ethernet network?
1.All frames are transmitted on all Ethernet segments 2. shared medium networks use CSMA/CD to access the medium
Ike any network Ethernet must have an algorithm for determining when each network node is allowed to communicate?
look up CSMA/CD.... these days each node can talk whenever it wants thanks to full duplex communication.
Mechanisms used on Ethernet networks to control access to transmission medium?
Csma/cd
What all ethernet networks independent of their speed or frame type and use an access called?
csma
Describe one protocol used for Local Area Network?
IP, appletalk, token ring, CSMA/CD, CSMA/CA
To 802.11 standard IEEE specifies what type of access method?
Network+ Guide to Networks answer: Csma/ca
What is collison domain?
A collision domain is a physical network segment where data packets can collide with one another when being sent on a shared medium.A group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected by repeaters and compete for access on the network. Only one device in the collision domain may transmit at any one time, and the other devices in the domain listen to the network in order to avoid data collisions.A collision domain is sometimes referred to as an Ethernet segment.
What is the drawback of the CSMA access method?
Collisions can decrease network performance.
