<span>the three fundamental elements of an effective security program for information systems are Identification, Authentication and Authorization.The access control creates the user and assigns the rights to resources and authorization is giving permissions to the users to access the resources.The user who wants to enter the system should have a valid data t enter the system like password, fingerprint or any other type of recognition.</span>
Answer:
A
Explanation:
Using hashes is preferred because encrypted IOS passwords can be easily decrypted.
Answer:
Due to unreachable DHCP server
Explanation:
As we know that Dynamic Host Configuration Protocol, in short DHCP is the network protocol which is used to central and automatic management of IP address with in the network.
So due to unreachable DHCP server a student could not able to connect with the internet.When the network connection break it means that DHCP server is offline.
So the answer is Due to unreachable DHCP server .
Answer:
Time Complexity of Problem - O(n)
Explanation:
When n= 1024 time taken is t. on a particular computer.
When computer is 8 times faster in same time t , n can be equal to 8192. It means on increasing processing speed input grows linearly.
When computer is 8 times slow then with same time t , n will be 128 which is (1/8)th time 1024.
It means with increase in processing speed by x factor time taken will decrease by (1/x) factor. Or input size can be increased by x times. This signifies that time taken by program grows linearly with input size n. Therefore time complexity of problem will be O(n).
If we double the speed of original machine then we can solve problems of size 2n in time t.
Answer:
The answer to this question as follows:
Explanation:
In option a, When we use fork, a new mechanism, that uses fork() method, which is in the parental process, to replicate all sites. It has been installed in a space-differentiating operating system.
In option b, It is the present system cycle that scan and wait for any of the system processor to be installed.
In option c, The time delay happens when A operates. It is a global that make issues, which are cleared and slowed down when an interrupt happens. In this process, there are not any distractions. It splits into slowly as it heads into the ISR. It helps to understand the code easily.
