Based on your understanding, explain a scenario that demonstrates how does CSMA/CD significantly solve the issues of signals collision in standard Ethernet LAN.
Answers
Answer:
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol for carrier transmission that operates in the Medium Access Control (MAC) layer. ... On detection of a collision, the station stops transmitting, sends a jam signal, and then waits for a random time interval before retransmission
Explanation:
participants usually meet on a common transmission medium – a cable. This meeting must be regulated to avoid chaos during data transmission, which could lead to data loss or damage. CSMA/CD offers a method that organizes data transmission properly.
This technique isn’t suitable for WLAN. Therefore, the process has been adapted in the form of CSMA/CA. CSMA/CD is no longer important for most wired networks, since new cable technology offers other possibilities. However, it doesn’t hurt to be knowledgeable of this older procedure as well.
To understand how CSMA/CD works, it makes sense to break down the individual components of the term:
Carrier sense (CS): The carrier state detection makes sure that all network participants check whether the medium is currently free – only then does the protocol initiate data transmission
Multiple access (MA): Several participants (computers connected to the network) share a transmission medium
Collision detection (CD): The collision detection is an extension of the original protocol and regulates how to proceed in case data packets happen to collide
