Total questions: 10
Worksheet time: 5mins
What is the purpose of dividing data into packets?
To make transmission more efficient and manageable
To increase the overall file size
To reduce the need for routers
To prevent the need for error checking
What part of a data packet contains the actual transmitted information?
Payload
Header
Trailer
Packet number
What does the packet header contain?
Metadata such as destination and originator’s address
The actual data being sent
Error correction information
The order in which packets are displayed
How do packets travel in packet switching?
Each packet may take a different route to its destination
Packets always take the same fixed path
Packets are transmitted one at a time without routing
Packets must be received in the exact order they were sent

Serial
Parallel
Half-Duplex
Full-Duplex
Which transmission method allows data to be sent in both directions at the same time?
Full-Duplex
Half-Duplex
Simplex
Serial
Which data transmission method is most suitable for long-distance communication?
Serial
Parallel
Simplex
Half-Duplex
Which of the following is an example of half-duplex communication?
Walkie-talkies
A keyboard sending input to a computer
A phone call
USB file transfer
What is the main advantage of using USB (Universal Serial Bus) for data transmission?
It is a widely supported standard for connecting peripherals
It can transmit data in parallel mode
It does not require serial communication
It only allows for one-way communication
How does USB transmit data between devices?
Using serial transmission, bit by bit
Using parallel transmission, multiple bits at once
Using packet switching across multiple networks
