Question 1: What are the main differences between TCP and UDP?

Answer:

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two of the most commonly used protocols in computer networks, but they have distinct differences in their operation.

• Connection-Oriented vs. Connectionless: TCP is a connection-oriented protocol, meaning it establishes a connection between the sender and receiver before data is exchanged. This ensures that data is reliably delivered and in the correct order. On the other hand, UDP is connectionless, meaning it does not establish a connection before sending data. This makes UDP faster but less reliable than TCP.

• Reliability: TCP guarantees reliable delivery of data by using acknowledgments, retransmissions, and sequencing to ensure that data is received in the correct order without errors. UDP, on the other hand, does not provide these mechanisms, so data may be lost or arrive out of order.

• Error Checking: TCP includes error-checking mechanisms to detect and correct errors in data transmission. UDP, on the other hand, does not perform error checking, so any errors in data transmission are not detected or corrected.

• Use Cases: TCP is commonly used for applications that require reliable, ordered delivery of data, such as web browsing, email, and file transfer. UDP is used for applications where speed and efficiency are more important than reliability, such as video streaming, online gaming, and real-time communication.

In summary, TCP is a reliable, connection-oriented protocol suitable for applications that require ordered delivery of data, while UDP is a faster, connectionless protocol suitable for applications where speed is prioritized over reliability.

Question 2: What is the significance of subnetting in computer networks?

Answer:

Subnetting is the process of dividing a larger network into smaller, more manageable subnetworks. This is done by allocating a portion of the network's IP address space to each subnetwork, allowing for more efficient use of IP addresses and better organization of network resources.

The significance of subnetting in computer networks can be understood in several key aspects:

• Address Space Optimization: Subnetting allows for more efficient use of IP addresses by dividing a large network into smaller subnetworks. This helps avoid address wastage and ensures that IP addresses are used more effectively.

• Improved Network Performance: By dividing a large network into smaller subnetworks, subnetting reduces the size of broadcast domains and limits the scope of broadcast traffic. This helps improve network performance by reducing network congestion and minimizing the impact of broadcast storms.

• Enhanced Security: Subnetting can also improve network security by logically isolating different parts of the network from each other. This can help prevent unauthorized access to sensitive network resources and mitigate the spread of network-based attacks.

• Simplified Network Management: Subnetting can make network management easier by dividing a large, complex network into smaller, more manageable segments. This allows network administrators to apply different network policies and configurations to each subnet, making it easier to troubleshoot and manage the network.

In conclusion, subnetting plays a crucial role in optimizing address space, improving network performance, enhancing security, and simplifying network management in computer networks.
