FAQs on Media Access Protocol Video Lecture - Computer Networks - Computer Science Engineering (CSE)

1. What is Media Access Protocol in Computer Science Engineering (CSE)?
Ans. Media Access Protocol in Computer Science Engineering (CSE) refers to the set of rules and procedures that govern the access of multiple devices to a shared communication medium. It determines how devices can transmit and receive data over the network, ensuring fair and efficient utilization of the available resources.
2. Which factors influence the choice of Media Access Protocol in CSE?
Ans. The choice of Media Access Protocol in CSE depends on several factors, including the type of network (e.g., wired or wireless), the number of devices connected, the desired data transfer rate, the level of priority for different types of data, and the network topology. Different protocols like Ethernet, Token Ring, and Wi-Fi use different media access methods to address these factors.
3. What are the advantages of using a Media Access Protocol in CSE?
Ans. Using a Media Access Protocol in CSE offers several advantages. It allows for multiple devices to share a common communication medium, enabling efficient utilization of network resources. It ensures fair access to the medium, preventing any single device from monopolizing it. Additionally, it helps in managing collisions and data collisions, improving the overall reliability and performance of the network.
4. Can you explain the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Media Access Protocol?
Ans. CSMA/CD is a Media Access Protocol commonly used in Ethernet networks. In CSMA/CD, devices listen to the network before transmitting data. If the network is idle, the device can transmit immediately. However, if another device is already transmitting, the device waits for a random period and then retries. This protocol also includes collision detection, where devices monitor the network for collisions and take appropriate actions to avoid data loss.
5. How does the Token Ring Media Access Protocol work in CSE?
Ans. The Token Ring Media Access Protocol is based on a logical ring topology where devices are connected in a ring formation. In this protocol, a special control frame, called the token, circulates around the ring. Only the device holding the token can transmit data. Once a device completes transmitting its data, it passes the token to the next device in the ring. This ensures fair and controlled access to the network, as each device gets a turn to transmit data.
