8 Questions
What are the two types of ALOHA systems?
Pure ALOHA and Slotted ALOHA
Why is collision somewhat common in contention systems?
Collision is somewhat common in contention systems because users share a common channel.
What does the term 'carrier' refer to in carrier sense networks?
The term 'carrier' refers to the electrical signal on the cable and has nothing to do with the common carrier.
Why is time division necessary in slotted ALOHA but not in pure ALOHA?
Time division is necessary in slotted ALOHA but not in pure ALOHA because slotted ALOHA requires global time synchronization, while pure ALOHA does not.
What is the name given to the event when two frames are transmitted simultaneously and overlap in time resulting in a garbled signal?
Collision
What is the key difference between Continues Time and Slotted Time in frame transmission?
Frame transmission can occur at any instant in Continues Time, while in Slotted Time, time is divided into discrete intervals where frame transmission always begins at the start of the slot.
What is the purpose of the Carrier Sense technique in stations in a network?
Stations use Carrier Sense to determine if the channel is in use before attempting to transmit.
What is the significance of the single channel assumption in LANs?
The single channel assumption is crucial as it ensures that all stations share the same communication medium and there are no external ways to communicate.
Explore the differences between continuous and slotted systems in networking, and how stations on carrier sense networks handle collisions. Understand how stations can terminate transmissions prematurely to avoid collisions. This quiz delves into Multiple Access Protocols and more.
