• FTP

• HTTPS

• SNMP

What is the primary role of the TCP protocol in data communication?

• Encrypting data

• Ensuring data is transmitted reliably

• Resolving IP addresses

• Detecting errors in data

Which of the following is NOT an error detection method?

• Parity Check

• CRC

• Checksum

• ROT13

What is the main purpose of a checksum in data transmission?

• To compress data for faster transfer

• To verify the integrity of transmitted data

• Bits per second (bps)

• Kilograms per second (Kps)

Which term describes the time it takes for a data packet to travel from the source to the destination?

• Throughput

• Bandwidth

• Jitter

• Latency

What is the difference between bandwidth and throughput?

• Bandwidth measures capacity, while throughput measures actual data transfer rate.
