The addition of control information to a packet as it moves through the layers is called encapsulation. Provide a brief overview of the process that requested pieces of data (packets) undergo as it is sent over the Internet. Include the difference between the size of a typical packet and the size of a typical Ethernet frame?
Define data communication? Briefly discuss how signals are clocked, include what is meant when a signal is self-clocking and how does the way in which signals are clocked affect data transmission? What is the relationship between frequency and Baud Rate?
Provide the results of these calculations:
What is the frequency, in Hertz, of a signal that repeats 60,000 times within one minute? What is its period (the length of one complete cycle)?
What is the bandwidth of a signal composed of frequencies from 60 Hz to 600 Hz?
