Quiz on Aloha Protocol and Multiple Access Protocols

What are the three outcomes of the lecture?

• Understanding the Aloha protocol

• Learning about network security

• Understanding the OSI model

• Knowing various multiple access protocols

What type of protocol is Aloha classified as?

• Channelization protocol

• Random access protocol

• Controlled access protocol

• Token ring protocol

What happens when two or more stations transmit data at the same time?

• Collision occurs

• Data is sent to a backup server

• Data is queued for later transmission

• Data is successfully received

What are the two types of Aloha mentioned in the lecture?

• Simple Aloha and Complex Aloha

• Fixed Aloha and Variable Aloha

• Controlled Aloha and Random Aloha

• Pure Aloha and Slotted Aloha

What is the main purpose of waiting for a random amount of time in Pure Aloha?

• To ensure data integrity

• To increase transmission speed

• To reduce network congestion

• To prevent collisions

What is the maximum throughput of Pure Aloha?

• 0.5

• 0.18

• 1.0

• 0.75

What is the vulnerable time in Pure Aloha?

• Equal to the frame transmission time

• Twice the frame transmission time

• Three times the frame transmission time

• Half the frame transmission time

What is the effect of non-uniform frame sizes on Pure Aloha?

• Has no effect on transmission

• Increases throughput

• Decreases chances of collision

• Increases chances of collision

What happens if an acknowledgment is not received on time?

• The data is sent to another station

• The station resends the data after a random time

• The station stops all transmissions

• The data is automatically deleted

What is the primary design purpose of the Aloha protocol?

• To optimize data storage

• To manage network security

• To facilitate wireless LAN communication

• To connect wired networks
