FAQs on PPT: Media Access Control - Computer Networks - Computer Science Engineering (CSE)

1. What is Media Access Control (MAC) in computer science engineering?
Ans. Media Access Control (MAC) is a sublayer of the Data Link Layer in computer networking. It is responsible for controlling access to a shared network medium, such as Ethernet, and ensuring that multiple devices can communicate efficiently without data collisions.
2. How does Media Access Control (MAC) address the issue of data collisions?
Ans. Media Access Control (MAC) implements various protocols, such as Carrier Sense Multiple Access with Collision Detection (CSMA/CD), to address the issue of data collisions. CSMA/CD allows devices to detect collisions and then take appropriate actions to retransmit the data without interference.
3. What are the different types of Media Access Control (MAC) protocols?
Ans. There are several types of Media Access Control (MAC) protocols, including CSMA/CD (used in Ethernet), CSMA/CA (used in Wi-Fi), Token Ring, and Demand Priority. Each protocol employs different strategies to manage access to the network medium.
4. How does Media Access Control (MAC) ensure fairness in network access?
Ans. Media Access Control (MAC) protocols often incorporate fairness mechanisms to ensure that each device on the network has a fair opportunity to access the network medium. For example, CSMA/CD uses random backoff timers to prevent devices from constantly accessing the medium, giving other devices a chance to transmit their data.
5. Can Media Access Control (MAC) protocols handle large-scale networks?
Ans. Yes, Media Access Control (MAC) protocols are designed to handle large-scale networks. However, as the number of devices increases, the chances of data collisions also increase. To mitigate this, advanced MAC protocols, like Carrier Sense Multiple Access with Enhanced Collision Avoidance (CSMA/ECA), have been developed to improve network efficiency in large-scale environments.
