The answer is;
Current
Voltage
Power/Wattage
Circuit
Water moving through pipes is like electricity flowing in a circuit. The flow of electricity is an actual flow of electrons. That movement of electrons is what is known as current. Think of current as the volume of water flowing through a water pipe. The electrons need some force or pressure to move, and so is water in a pipe. The voltage is that electromotive force; the pressure that pushes the electrons in a system. The power measured in Watts is the rate at which the energy is consumed. For the current to flow the circuit must be complete. Otherwise we cannot say that we have power if the circuit is not closed.
Answer:
b. P2 requests drive 2 and gets it.
Explanation:
Two users from the local board of education are each running a program (P1 and P2), and both programs will eventually need two DVD drives to copy files from one disc to another. Only two DVD-R drives are available and they’re allocated on an "as requested" basis. Soon the following sequence transpires: P2 requests drive 2 and gets it.
Answer: <u>Bill Gate</u>, who is known as the king of computer programs
Hope this helps!
As far as I remember, message-digest functions distill the information contained within a file (small or large) into a single fixed-length<span>number, typically between 128 and 256 bits in length. This function is designed to protect the integrity of a piece of data to define changes to any part of a message.</span>
Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
