Explanation/Reference:
* UDP uses a simple connectionless transmission model with a minimum of protocol mechanism. User datagram protocol (UDP) provides a thinner abstraction layer which only error-checks the datagrams.
Note: Best-effort delivery describes a network service in which the network does not provide any guarantees that data is delivered or that a user is given a guaranteed quality of service level or a certain priority.
* Transmission control protocol (TCP) provides a guaranteed delivery of an octet stream between a pair of hosts to the above layer, internally splitting the stream into packets and resending these when lost or corrupted.
* Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address (MAC address) that is recognized in the local network.

What are two characteristics of a mesh network topology? (Choose two.)
- A. It works best for networks with a large number of nodes.
- B. Every node connects to every other node on the network.
- C. It requires less cabling than either a star or ring topology.
- D. It is fault tolerant because of redundant connections.
Answer: B,D
Explanation:
Explanation/Reference:
In a (full) mesh network topology, each of the network node, computer and other devices, are interconnected with one another. Every node not only sends its own signals but also relays data from other nodes. In fact a true mesh topology is the one where every node is connected to every other node in the network. This type of topology is very expensive as there are many redundant connections, thus it is not mostly used in computer networks. It is commonly used in wireless networks.
