Total questions: 15
Worksheet time: 8mins
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.
What mechanism does the Transport Layer use to ensure data integrity?
Data integrity is ensured by the application layer protocols.
Data integrity is ensured through physical layer checks.
The Transport Layer uses checksums to verify data integrity.
Data integrity is not a concern for the Transport Layer.
What is the significance of the three-way handshake in TCP?
It is used to establish a secure connection between two devices.
The three-way handshake is used to establish a reliable connection by synchronizing sequence numbers between sender and receiver.
It is a method for data encryption.
It is a technique for error correction in data transmission.
What is the function of a router in a network?
To provide a physical connection for devices.
To filter and forward data packets between different networks.
To connect multiple devices within the same network.
To encrypt data for secure transmission.
What is the purpose of a subnet mask in networking?
A subnet mask is used to establish a physical connection between devices.
A subnet mask is a type of hardware used in networking.
A subnet mask defines the network and host portions of an IP address.
A subnet mask is used to encrypt data packets.
How does NAT (Network Address Translation) enhance security in a network?
NAT hides internal IP addresses from external networks, making it harder for attackers to target specific devices.
NAT is used to increase the speed of data transmission.
NAT encrypts all outgoing and incoming data packets.
NAT provides a dedicated connection for each device on the network.
