Please help me answer these questions

1. True or False: Packet switching req uires control and address bits to be added to each packet. This causes considerable overhead in packet-switching. However, circuit switching does not need extra bits are needed because it establishes a circuit. Thus, there is no overhead in circuit switching and the line utilization of circuit switching must be more efficient than in packet switching. Justify vour answer. (2 points) 2. Discuss pros and cons when a computer send many packets instead of an entire message over the Internet. (2 points) 3. Why we want to standardize protocols? (2 points) 4. Discuss two advantages and two disadvantages of developing a layered protocol? (2 points) 5. Match the following to one layer of Internet protocol stack and give two examples for each layer protocol you matched.

Responsible for handling frames between adjacent nodes Name of layer examples Providing services for the end users: Name of layer c. examples d. Responsible for communication from an application process on one computer to an application process on another host: Name of layer examples 6.
