Answer:
The maximum Data transfer rate is 320 Mb/s
Explanation:
The minimum microprocessor bus cycle duration = 100 input clock cycles and Data bus clock = 4.0 GHz = 4 × 10⁹ Hz
The maximum bus cycle rate = Data bus clock/minimum microprocessor bus cycle duration
Therefore, The maximum bus cycle rate = 4.0 GHz/100 = 4 × 10⁹ / 100 = 4 × 10⁷ = 40 × 10⁶ = 40 M/s
8 bits is equal to 1 byte, therefore 64 bit is equal to (64/8 = 8) byte.
Data transferred per bus cycle = 64-bit = 8 bytes.
The maximum Data transfer rate per second = bus cycle rate × data transferred per bus cycle = 40 M/s × 8 bytes = 320 Mbytes/s = 320 Mb/s.
The maximum Data transfer is 320 Mb/s
Answer:
Challenge-Handshake Authentication Protocol (CHAP).
Explanation:
In Computer technology, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.
In this scenario, an organization wants to implement a remote dial-in server to ensure that personnel can connect to the organization's network from remote locations. The authentication protocol must include encryption to prevent hackers from accessing the network.
Hence, the protocol which should be used is Challenge-Handshake Authentication Protocol (CHAP).
A Challenge-Handshake Authentication Protocol (CHAP) can be defined as a standard network access control protocol in which a client program dials in to a network access server to receive a random value and identification number that can only be used once.
