Networking Protocols Explained

CSMA/CD (Carrier Sense Multiple Access with Collision Detection)

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. It senses or listens to whether the shared channel for transmission is busy or not, and defers transmissions until the channel is free. The collision detection technology detects collisions by sensing transmissions from other stations.

Data Link Layer: Protocols and Topologies

Posted by admin on Mar 11, 2025 in Cinema | 0 comments

The data link layer provides a means to exchange data using common local media. It performs two basic services:

• Allows upper layers to access the media using techniques such as frames.
• Controls how data is placed in and received from the media using techniques such as media access control and error detection.

The frame is a key element of each data link layer protocol. Data link layer protocols include control information that enables the protocols to function. This control information may indicate:
