applications may use the capabilities of two different transport-layer protocols (UDP or TCP). When a packet finally reaches its destination, how does the computer know which transport layer to use?

TCP and UDP are two transport layer protocols that are in opposition to one another.

The levels of the categorization system are used to categorize network protocols.

Define demultiplexing. Briefly explain how TCP demultiplexing is different than UDP demultiplexing.

Why do transport protocols such as HTTP, FTP, SMTP, and POP3 use TCP as opposed to UDP?

Explain the principles of routing protocols in computer networks. What are some commonly used routing algorithms, and how do they determine the best path for data packets?

Two transport-layer protocols offer services that certain applications may make use of (UDP or TCP). So, when a packet arrives at its destination, how can a computer tell which transport layer is involved?

In certain cases, applications may make advantage of services provided by both of these transport-layer protocols (UDP or TCP). Because of this, how can a computer determine whichever tier of the transport stack is responsible for sending a packet?

A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.How does a router distribute bandwidth in networks.

Some applications may utilise the capabilities of both UDP and TCP transport-layer protocols. How does the computer know which transport layer to employ when a payload ultimately reaches its destination?
