CSMA/Ethernet

What does CSMA stand for?

• Carrier Switch Multiple Access

• Carrier Sense Multiple Access

• Channel Sense Multiple Access

• Channel Shared Medium Access

In CSMA/CD, what does CD stand for?

• Carrier Detection

• Collision Detection

• Channel Decoding

• Code Division

What is the main difference between CSMA/CD and CSMA/CA?

• CSMA/CA detects collisions

• CSMA/CD prevents collisions

• CSMA/CA avoids collisions, while CSMA/CD detects them

• CSMA/CD is used in wireless networks

Which medium access protocol is primarily used in Ethernet?

• ALOHA

• CSMA/CA

• Token Ring

• CSMA/CD

In ALOHA protocol, what happens when a collision occurs?

• The data is queued

• The system stops working

• The data is retransmitted after a random delay

• An error message is sent

Which of the following fields is NOT part of a standard Ethernet frame?

• Destination MAC Address

• Source MAC Address

• Frame Check Sequence (FCS)

• Time-To-Live (TTL)

What is the main improvement Slotted ALOHA has over Pure ALOHA?

• Uses a dedicated channel for each user

• Allows simultaneous transmissions

• Limits transmissions to synchronized time slots

• Eliminates the need for retransmission

CSMA/CD is mostly used in which type of network?

• Wireless

• Bluetooth

• Wired Ethernet

• Optical fiber

Which protocol is most suitable for wireless communication?

• CSMA/CD

• CSMA

• CSMA/CA

• ALOHA

Why can't CSMA/CD be used in wireless networks?

• Too expensive

• Requires high power

• Cannot detect collisions due to signal attenuation

• Cannot transmit data
