Options: always increases as the applied frequency increases, is equal to the sum of the values of resistance, inductive reactance and capacitive reactance, always decreases as the applied frequency increases, is maximum at the resonant frequency
Which of the following is true for machine language.
Options: Repeated execution of program segments, Depicting flow of data in a system, A sequence of instructions which, when followed properly, solves a problem, the language which communicates with the computer using only the binary digits 1 and 0.
Which of the following is true when describing a unique local address?
Options: Packets addressed to a unicast address are delivered to a single interface., These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4., These are like private addresses in IPv4 in that they are not meant to be routed., These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
