Answer:
Explanation:There are several types of data that do not change unless they are manually altered:
Constants: Constants are values that do not change and are used to represent fixed quantities in a mathematical or programming context. Examples include pi (3.14), the speed of light (299,792,458 m/s), and the gravitational constant (6.674 x 10^-11 N*m^2/kg^2).
Read-only data: Read-only data is data that cannot be modified or altered by the user. This type of data is often used to store important information such as system settings or configuration data.
Immutable data: In programming, immutable data refers to data that cannot be modified once it has been created. Examples of immutable data types include strings, tuples, and integers in some programming languages.
Final variables: In programming, final variables are variables that cannot be modified once they have been initialized. They are often used to store constants or important data that should not be changed.

A_______type of bn is a new type of lan/bn architecture made possible by intelligent, high speed switches that assign computers to lan segments via software, rather than by hardware.
A routed backbone guarantees that broadcast messages remain in the network segment (i.e., subnet) to which they are intended and are not transmitted to all machines.
What is the name of a network’s backbone?A backbone or core network is a component of a computer network that links networks and provides a conduit for information exchange across multiple LANs or subnetworks. A backbone can connect heterogeneous networks inside the same building, across campus buildings, or over large distances.
A backbone is a high-speed line or collection of lines that forms the quickest (in terms of bandwidth) path across a network. It frequently serves as a met network. The main drawbacks are that they tend to impose time delays when compared to bridging and require more administration than bridges and switches.

On which of the following is the live acquisition of data for forensic analysis MOST dependent? (Choose two.)
A. Data accessibility
B. Legal hold
C. Cryptographic and hash algorithm
D. Data retention legislation
E. Value and volatility
F. Right-to-audit clauses
The live acquisition of data for forensic analysis is most dependent on A. Data accessibility and E. Value and volatility
What is live acquisition?Live acquisition, also known as live forensic analysis or live forensics, refers to the process of collecting and analyzing data from a running computer system or device in real-time.
This is in contrast to traditional forensic analysis, which involves collecting and analyzing data from a device that has been shut down or is no longer in use.
Live acquisition is often used in situations where it is important to preserve the integrity of the data being collected and to minimize the risk of data loss or alteration.
For example, it may be used in the case of an active cyber attack, in order to gather evidence and track the actions of the attacker in real-time.
Live acquisition involves a number of steps, including identifying and preserving the data to be collected, establishing a secure connection to the target system, collecting and analyzing the data, and preserving the collected data for use as evidence.
It requires specialized tools and techniques, and may involve working with other forensic experts and law enforcement agencies.

The application of quicksort to sort the array {45, 31, 71, 90, 29, 12, 10} is given below.
What is the quick sort?To apply Quicksort to the array {45, 31, 71, 90, 29, 12, 10}, we can follow these steps:
Choose a pivot element. This can be any element in the array, but a common choice is the first element. In this case, we will choose 45 as the pivot.Divide the array into two subarrays. One subarray will contain all elements that are less than the pivot, and the other will contain all elements that are greater than or equal to the pivot. In this case, the subarrays would be {31, 29, 12, 10} and {71, 90}.Recursively sort each subarray. To sort the first subarray, we can choose 29 as the pivot and divide the subarray into {31, 12, 10} and {29}. We can then choose 31 as the pivot for the first subarray and divide it into {12, 10} and {31}. We can then choose 12 as the pivot for the first subarray and divide it into {10} and {12}. At this point, the first subarray is already sorted, so we can move on to the second subarray. To sort the second subarray, we can choose 71 as the pivot and divide it into {} and {71, 90}. We can then choose 90 as the pivot for the second subarray and divide it into {71} and {90}. At this point, both subarrays are sorted.Combine the sorted subarrays. To combine the sorted subarrays, we simply append the first subarray to the pivot element and then append the second subarray to the result. In this case, the final sorted array would be {10, 12, 29, 31, 45, 71, 90}.Therefore, last swap occurs when we are sorting the second subarray and swap 71 and 90 to get the final sorted array. The first swap occurs when we are sorting the first subarray and swap 10 and 12. The total number of swaps is 4, because we had to swap 10 and 12 in the first subarray, 31 and 29 in the first subarray, and 71 and 90 in the second subarray. The total number of comparisons is 11, because we had to compare each element to the pivot element at least once while dividing the array into subarrays and sorting the subarrays.
