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 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 primary function of csma CD in an Ethernet network?
it prevents the collision between the data that is sended by the network cards over ethernet networks
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.
How many components of computer system?
The Major components of the typical desktop computer are the following: CPU (central processing unit) RAM (Random Access Memory) Hard Drive CD/DVD/BluRay/CD-ROM drive (optional) Video Card
Which access method is used by Ethernet?
CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
Which is an access method in which collision is entirely avoided?
Csma/cd
What type of access method are used when network devices listen to the cable before transmitting?
CSMA/CD (Carrier Sense Multiple Access / Collision Detect)
What access method specifies that each node must first listen to the network medium to determine if the medium is currently free of packets?
The access method is CSMA/CD - carrier sense multiple access with collision detect.
What is the access method for star topologies?
Most star topologies use CSMA/CD for a Local Area Network. WANs and MANs are different and use completely different access methods.
What does the acronym CSMA CD stand for?
The acronym CSMA CD stands for Carrier Sense Multiple Access with Collision Detection. CSMA CD is a set of rules determining how network devices respond when two devices attempt to use a data channel simultaneously.
Mechanisms used on Ethernet networks to control access to transmission medium?
Csma/cd

What 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.
Explain the functioning of the main LAN access control methods?
to access your lan There are a number of different well known access methods: * CSMA/CD * Token passing * Slotted ring The most commont being CSMA/CD (Carrier Sense Multiple Access with Collision Detection) used in the Ethernet LAN environment.
