The Physical layer protocols govern the exchange of binary digits (bits) across a physical communication channel, such as a fiber-optic cable, copper wire, or wireless radio channel. These protocols specify such things as:• How we know when a bit is present on the line• How much time the bit will remain on the line• Whether the bit is in the form of a digital or an analog signal• What physical quantities are used to represent a binary 0 and a binary 1• The shape of the connector between the computer and the transmission lineThe goal of the Physical layer is to create a "bit pipe" between two computers, such that bits put into the pipe at one end can be read and understood by the computer located at the other end.

The string class provides which function to determine the number of characters contained in a string variable?
A. numchars B. length C. total D. chars
Write a method called multiConcat that takes a String and an integer as parameters. Return a String that consists of the string parameter concatenated with itself count times, where count is the integer parameter. For example, if the parameter values are "hi" and 4, the return value is "hihihihi". Return the original string if the integer parameter is less than 2.
