TCP/IP Network and Transport Layers

What is the primary function of the Transport Layer?

• To encrypt data for secure transmission.

• To provide reliable data transfer and communication between applications.

• To manage network congestion and traffic flow.

• To establish physical connections between devices.

What is the difference between TCP and UDP?

• UDP guarantees delivery of packets, while TCP does not.

• TCP is reliable and connection-oriented, while UDP is faster and connectionless.

• TCP is faster and connectionless, while UDP is reliable and connection-oriented.

• TCP and UDP are both connection-oriented protocols.

What is the role of the Internet Protocol (IP)?

• To provide a user interface for applications.

• To manage user accounts on a network.

• To encrypt data for secure transmission.

• The role of the Internet Protocol (IP) is to address and route data packets between devices on a network.

Explain the concept of packet switching.

• Packet switching involves sending data in a continuous stream without segmentation.

• Packet switching is a method of transmitting data by breaking it into packets that are sent independently over a network.

• Packet switching requires a dedicated connection for each transmission.

• Packet switching is a method used only in wireless networks.

What is a port number in networking?

• A port number is a type of hardware used in networking.

• A port number is a physical location for connecting devices.

• A port number is a protocol used for data encryption.

• A port number is a numerical identifier used to specify a particular process or service in networking.

How does TCP ensure reliable data transmission?

• TCP does not require any form of error checking.

• TCP uses UDP for data transmission.

• TCP ensures reliable data transmission through sequence numbers, acknowledgments, retransmissions, flow control, and error checking.

• TCP relies on physical connections for reliability.

What is the purpose of the Network Layer?

• To provide a user interface for network applications.

• To manage user authentication across networks.

• To encrypt data for secure transmission.

• To facilitate the transfer of data packets between devices across different networks.

What type of connection does TCP provide?

• Connectionless

• Stateless

• Unreliable

• Connection-oriented

How does the Transport Layer handle flow control?

• The Transport Layer uses encryption to manage flow control.

• Flow control is handled by the Network Layer through routing protocols.

• The Transport Layer handles flow control using mechanisms like sliding window protocols to prevent overwhelming the receiver.

• The Transport Layer does not implement any flow control mechanisms.

What is the main advantage of using UDP over TCP?

• UDP provides guaranteed delivery of packets.

• UDP is faster and has lower latency due to its connectionless nature.

• UDP is more reliable than TCP.

• UDP is used exclusively for video streaming.
