• 32 KiB

• 128 KiB

• 256 KiB

What does the packet header contain?

• Only the payload

• Only the trailer

• Only error checking

• IP addresses and sequence number

What is the purpose of the sequence number in a packet?

• To check for errors

• To identify the sender

• To ensure correct reassembly

• To indicate packet size

What does the packet trailer help identify?

• The sender's IP address

• The end of the packet

• The size of the payload

• The sequence number

What is packet switching?

• Sending data in one continuous stream

• Using a single route for all packets

• Breaking a message into packets for independent transmission

• Sending data only in one direction

What is simplex mode in data transmission?

• Data sent in both directions simultaneously

What is the main advantage of serial data transmission?

• Sends multiple bits at once

• More error-prone

• Works well over long distances

• Faster than parallel transmission

What can happen to data in parallel transmission over long distances?

• Data arrives faster

• Data arrives unsynchronized

• Data is always in the correct order

• Data is sent one bit at a time
