A computers CPU and the hard drive are found in the system unit. The correct answer is C. <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.
False, A prototype is a beginning model to a to be further developed piece of technology.
Answer: Near field communication
Explanation:
The near field communication is one of the type of technology in which any two devices are communicating with each other by sharing the data or any information on the basis of some communication protocols.
- The near filed communication technology is basically used for sharing any type of information or data over the short distance like less than 4 cm.
- The main part of this communication technology is NFC chip as it offering low speed link and it is also known as the effective wireless communication medium.
According to the given question, the Near field communication technology works by using the NFC microchip and with the helps in this the communication become more effective with the other devices.
Therefore, Near field communication is the correct answer.
