What are the two types of CSMA?
There are 2 (or 3) types of CSMA protocols:
- Non-persistent CSMA (the whimp)
- 1-persistent CSMA (the stalker) (General case: p-persistent CSMA (the gambler))
What is the main advantage of CSMA CD over CSMA?
Table 6.1. Advantages and Disadvantages of CSMA/CD
| Advantages | Disadvantages |
|---|---|
| It has low overhead. | Collisions degrade network performance. |
| Utilizes all available bandwidth when possible. | Priorities cannot be assigned to certain nodes. Performance degrades exponentially as devices are added. |

What’s the difference between CSMA / CA and CSMA-CD?
CSMA/CA initially transmits the intent to send the data, once an acknowledgment is received, the sender sends the data. CSMA/CD resends the data frame in case a conflict occurs during transmission. CSMA/CA is part of the IEEE 802.11 standard. CSMA/CD is part of the IEEE 802.3 standard.
When to use CD / CSMA and CSMA / CD-propatel?
Among them, CD/CSMA and CSMA/CA are widely deployed in many networks such as Ethernet and wireless. These techniques senses before sending the data over different type of networks. The CSMA/CD is used in wired local area networks and CSMA/CA used in wireless local area networks and other types of wireless networks.
How does collision detection work in CSMA / CD?
Upon collision detection in CSMA/CD, the transmission is stopped and a jam signal is sent by the stations and then the station waits for a random time context before retransmission. CSMA/CA stands for Carrier Sense Multiple Access / Collision Avoidance is a network protocol for carrier transmission.
How does CSMA work in a broadcast network?
It is also a network protocol for transmission and operates in the Medium Access Control Layer. In this protocol, each station senses the collision by broadcast sensing. In case of collision, the transmission is stopped and they send a jam signal and then wait for a random time context before retransmission.
