Answer:
The given statement is "True". A further explanation is given below.
Explanation:
- Multi level paging can conserve storage capacity as opposed to sequential paging, including some of its hierarchical method Multi-level paging completing such.
- Rather precisely, with either the aid of the number of co-association, clients will determine which unique category of 2²⁰ pages whose data are stored as well as the pick itself.
Answer:
C. DAT-1
Explanation:
Chain of custody is applied when examining digital evidence and checking for proof that no alterations have been made to the document. It ensures that the original piece of digital evidence which could be in text, image, video, or other electronic formats, is preserved and protected from alterations. Hashing algorithms which are mathematical computations that help to condense files are applied during this procedure.
Common hashing algorithms applied, include; the message digest 4, secure hashing algorithms 1, 2, 256, 224, 512, etc. The message digest 4 is used to evaluate why a particular piece of evidence was handled by an individual. This is further authenticated by examining the fingerprint.
Answer:
Option B is the correct option.
Explanation:
The following answer is true because when the person completed our training of a decision tree and after the following presentation he getting not good working performance on both side i.e., test sets and during the training period. After the training there is no bug on the implementation of the presentation then, he has to increase the rate of the learning.
Answer:
Importance of backup in system administration:
Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.
Three methods for performing backup:
- Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.
- External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go.
- Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.
Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
int recurs(int x, int n)//defining a method recurs that accepts two parameter
{
if(n==0)//defining if block that checks n value
{
return 1;//return value 1
}
else//defining else block
{
return x*recurs(x,n-1);//use return keyword that retun value
}
}
int main()//defining main method
{
cout<<recurs(5,3); //use print method to call recurs method
return 0;
}
Output:
125
Explanation:
In the above-given program, the integer method "recurs" is declared which accepts, two integer variables, which are "x, n", inside the method the if conditional statement is used.
- In the if block, it checks the value of n is equal to "0" if this condition is true, it will return a value, that is 1.
- Otherwise, it will go to the else block, in this block, it will use the recursive method to print its value.
