Understanding IPs and Network Routing

What is the purpose of an IP address in a network?

• The purpose of an IP address in a network is to uniquely identify a device and facilitate communication between devices.

• To store user credentials for network access

• To encrypt data transmitted over the network

• To provide a physical address for devices

Explain the difference between IPv4 and IPv6.

• IPv4 uses 64-bit addresses and is more secure than IPv6.

• IPv4 and IPv6 both use the same number of addresses, around 4 billion.

• IPv4 is a 32-bit address scheme with about 4.3 billion addresses; IPv6 is a 128-bit scheme with vastly more addresses and additional features.

• IPv4 is a newer protocol that supports more devices than IPv6.

What is network congestion and what causes it?

• Network congestion is a result of physical damage to cables.

• Network congestion is caused by outdated software only.

• Network congestion occurs when there is too little data being transmitted.

• Network congestion is a state where network performance degrades due to excessive data traffic, caused by high demand, limited bandwidth, or hardware inefficiencies.

Describe the role of routing algorithms in data transmission.

• Routing algorithms only function in wireless networks.

• Routing algorithms are irrelevant in modern data transmission.

• Routing algorithms are only used for network security.

• Routing algorithms play a crucial role in optimizing data transmission by determining the most efficient paths for data packets across a network.

What is the function of a router in a computer network?

• To provide a physical connection between devices.

• To encrypt data for secure transmission.

• The function of a router in a computer network is to direct data packets between different networks.

• To store data packets for later use.

How does congestion control help in network performance?

• Congestion control improves network performance by preventing overload, reducing packet loss, and minimizing delays.

• Congestion control has no impact on network performance or reliability.

• Congestion control increases network speed by allowing more data to flow simultaneously.

• Congestion control eliminates the need for data packets in the network.

What are the common types of routing algorithms?

• Static, dynamic, reactive

• Flooding, spanning tree, multicast

• Distance-vector, link-state, path-vector, hybrid

• Unicast, broadcast, anycast

Define static routing and dynamic routing.

• Static routing is manually configured and does not change unless updated; dynamic routing uses protocols to automatically adjust routes.

• Static routing automatically adjusts routes based on traffic

• Static routing is faster than dynamic routing

• Dynamic routing requires manual configuration

What is the significance of subnetting in IP addressing?

• Subnetting complicates network routing.

• Subnetting is significant in IP addressing as it optimizes network management and enhances security.

• Subnetting reduces the number of IP addresses available.

• Subnetting is only used for large organizations.

How do routing tables assist in directing network traffic?

• Routing tables assist in directing network traffic by providing the necessary information for routers to determine the best path for data packets to reach their destination.

• Routing tables determine the physical location of network devices.

• Routing tables are used to encrypt data packets during transmission.

• Routing tables store user credentials for network access.
