ACI - Module 5 Part 1

Which of the following is a key concept and functionality of TCP?

• Connection establishment

• Data encryption

• Wireless communication

• Signal modulation

Answer explanation

The key concept and functionality of TCP is connection establishment, allowing for reliable communication between devices.

What does TCP stand for?

• Transmission Control Protocol

• Transfer Communication Protocol

• Transmission Communication Protocol

• Transfer Control Protocol

Answer explanation

TCP stands for Transmission Control Protocol, which is the correct choice among the options provided.

Which of the following is NOT a key concept of TCP?

• Reliability

• Flow control

• Connection termination

• Data compression

Answer explanation

The correct choice is Data compression because it is NOT a key concept of TCP. The other options - Reliability, Flow control, and Connection termination are key concepts of TCP.

What is the primary purpose of TCP?

• To establish and maintain a reliable data exchange over an IP network

• To encrypt data for secure transmission

• To provide wireless communication protocols

• To modulate signals for transmission

Answer explanation

The primary purpose of TCP is to establish and maintain a reliable data exchange over an IP network.

What process does TCP use to connect a client and a server?

• Two-way handshake

• Four-way handshake

• Three-way handshake

• Five-way handshake

Answer explanation

TCP uses a Three-way handshake process to connect a client and a server, establishing a reliable connection by exchanging SYN and ACK packets.

How does TCP ensure reliable data delivery?

• By using checksums

• By using acknowledgments and sequence numbers

• By using flow control mechanisms

• By using error detection and recovery

Answer explanation

By using acknowledgments and sequence numbers

What mechanism does TCP use to prevent overwhelming network resources?

• Error detection

• Sequence numbering

• Flow control

• Connection termination

Answer explanation

TCP uses flow control to prevent overwhelming network resources by regulating the amount of data sent to match the receiver's processing speed.

What does TCP use to detect errors in data transmission?

• Sequence numbers

• Checksums

• Flow control

• Acknowledgments

Answer explanation

TCP uses checksums to detect errors in data transmission by calculating a checksum value for the data and comparing it at the receiving end to ensure data integrity.

What process does TCP follow to gracefully terminate a connection?

• Two-way handshake

• Three-way handshake

• Four-way handshake

• Five-way handshake

Answer explanation

TCP follows a Four-way handshake process to gracefully terminate a connection.

What does UDP stand for in the context of networking?

• User Datagram Protocol

• Universal Data Protocol

• Unified Data Packet

• User Data Packet

Answer explanation

UDP stands for User Datagram Protocol in the context of networking.
