There is no truly unique identifier assigned to a PC. Any appearance of a unique ID is merely an illusion. The closest thing there is to a unique identifier is a MAC address, which is actually assigned to a network adapter (Ethernet port, wireless radio, etc.) and is usually unique but can be faked
Answer:
a. 100.
b. 31500.
Explanation:
So, we are given the following data which is going to help in solving this particular question.
The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.
Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.
The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.
The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.
Assuming U = 1.
Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.
=0.667 + 15.083.
= 15.75 millisecond.
Average number of instruction = 15.75/0.0005 = 31500.
Answer:
Static IP allocation
Explanation:
Static IP allocation is the assigning of a fixed IP address to a device that can be shared on a network such as a server or a printer. With a static IP address, the printer or server can be reached any time by any user that is on the network, using the same IP address that was configured at initial setup. However, with a dynamic IP address, it means devices connecting to the printer or server have to be constantly configured to be able to connect to the printer or server, as the IP address is constantly changing,
Answer:
Threat
Explanation:
In risk management, the hacking group would be considered a Threat. This is because a threat is anything that is able to analyze, find, and take advantage of vulnerabilities of your system. This applies regardless of the intentions of the group. In this case, the hacking group is using various tools to exploit specific existent vulnerabilities in Mary's companies database servers and would therefore classify as a Threat. In risk management, this is serious and is usually a priority that needs to be dealt with.
