For Local Area Network (LAN), CSMA/CD works optimally but for long-distance networks like WAN, it’s not advisable to use CSMA/CD. If the length of the packet is bigger, then the efficiency increases but then again there is a limitation. The maximum limit for the length of the packets...
There are several CSMA (Carrier Sense Multiple Access) modes: 1-persistent, P-persistent, and O-persistent. 1-persistent is used in CSMA/CD systems, like Ethernet. This mode waits for the medium to be idle, then transmits data. P-persistent is used in CSMA/CA (collision avoidance) ...
If both transmitters do not detect the collision, they will not attempt to repeat the process. As a result, CSMA/CA has its limitations. It is also the reason why an optional extension called Request to Send/Clear to Send (RTS/CTS) was created. What is the difference between CSMA/CA an...
CSMA is an acronym for carrier sense multiple access. CD, in this context, stands for collision detection. In LAN or local area networks, this is a method used by network protocols to control a computer’s access to the network and the communication channels in it. For multiple computers in...
What is CSMA/CA? The full name of CSMA/CA is Carrier sense multiple access with collision avoidance, which is mostly used for wireless LAN communication and is based on IEEE 802.11 protocol. From its name, we can see its design idea: ...
Carrier Sense Multiple Access (CSMA) is a network protocol that listens to or senses network signals on the carrier/medium before transmitting any data. CSMA is implemented in Ethernet networks with more than one computer or network device attached to it. CSMA is part of the Media Access Contro...
CSMA/CA, however, aims to avoid collisions (as the name suggests) instead of just recognizing them. If a collision does occur, a corresponding protocol is established. In this respect, CSMA/CA is an adaptation of CSMA/CD to another transmission medium. ...
Gartner defines cybersecurity mesh architecture (CSMA) as “a composable and scalable approach to extending security controls, even to widely distributed assets. Its flexibility is especially suitable for increasingly modular approaches consistent with hybrid multicloud architectures. CSMA enables a more com...

Compared to wired networks, state two reasons why CSMA/CD is not appropriate in the context of wireless networks. What is the difference between the personal contact model of communicating on the web and the mass media approach? What is the primary disadvantage of using algorithms?
