The correct answer is C. Anti-virus software is set to scan your computer weekly.

Explanation:

In technology, anti-virus software aims at identifying and stopping the actions of viruses that spread in the host and alter normal functioning leading to issues in cybersecurity or damages in the software of a technological device. Additionally, for anti-virus software to be effective, the software needs to be updated, perform routine scans daily or almost daily and scan all elements download. This implies, if the anti-virus software is set to scan your computer weekly this might not prevent a computer virus because a virus can infect your computer and be unnoticed for several days. Thus, the one that is least effective at preventing computer virus is "Anti-virus software is set to scan your computer weekly".

Which biometric technique is considered nearly infallible from a scientific point of view and is increasingly preferred by crimi

Sergio039 [100]

Answer:

DNA analysis

Explanation:

DNA is unique for all individuals. DNA analysis is the process of analysing the DNA characteristics of an individual.

DNA profiling is used in forensics to identify the suspects involved in criminal activities.

1. In the process, DNA of the suspects is matched with the DNA found in the site of the crime.

2. If a match is found, it indicates that the genetic relationship exists between the suspect and the criminal or the crim.

3. The order from the court is needed to obtain the DNA of the suspects. The sample can be in the form of blood or saliva.

4. The sample obtained should have adequate cells which contain the DNA.

Issues

The DNA obtained from the crime site is not pure or proper enough to be ideal for the DNA profiling.

Degraded sample

1. The sample obtained from the site of the crime is not always adequate to obtain the actual DNA.

2. The sample can be contaminated due to the environmental factors.

3. The sample obtained is too less and hence, should be examined accurately in order not to waste the sample.

DNA mixture

4. The sample obtained from the site of the crime is found to contain DNA from more than one individual.

Profiling types

DNA profiling can be carried out by using any of the techniques mentioned below.

1. RFLP analysis ( Restriction fragment length polymorphism )

This uses the Southern blot technique. The blot process needs a large amount of the sample. Also, this works well only when the sample is not degraded.

2. Polymerase chain reaction (PCR) analysis

3. STR analysis ( short tandem repeats )

4. AFLP ( amplified fragment length polymorphism )

This is an automated and low-cost process. It is easy to set up and operate which makes this process common in low income countries.

All the methods mentioned above have their own advantages and drawbacks.

BlackZzzverrR [31]

Answer:

The program written in Java without comment is as follows

import java.util.*;

public class MyClass {

public static void main(String args[]) {

Scanner input = new Scanner(System.in);

System.out.print("Year: ");

int y = input.nextInt();

int a = y%19;

System.out.println("a = "+a);

int b = y / 100;

System.out.println("b = "+b);

int c = y%100;

System.out.println("c = "+c);

int d = b / 4;

System.out.println("d = "+d);

int e = b%4;

System.out.println("e = "+e);

int g = (8 * b + 13)/25;

System.out.println("g = "+g);

int h = (19 * a + b - d - g + 15)%30;

System.out.println("h = "+h);

int j = c/4;

System.out.println("j = "+j);

int k = c%4;

System.out.println("k = "+k);

int m = (a + 11 * h)/319;

System.out.println("m = "+m);

int r = (2 * e + 2 * j - k - h + m + 32)%7;

System.out.println("r = "+r);

int n = (h - m + r + 90)/25;

System.out.println("n = "+n);

int p = (h - m + r + n + 19)%32;

System.out.println("p = "+p);

}

Javier develops sophisticated fashion websites. He has been asked by the owner of a leading fashion brand to create web content

saul85 [17]

Answer:

hyperlinks

Explanation:

Javier should use hyperlinks to show the users the possible choices for their clothing. This is really a terrible question and not likely in any real world scenario. Fashion is always forward thinking and on the cutting edge. When was the last time you went to a fashion website and were left with only choices to click on a hyperlink? As Tim Gun would say "Make it work." If I were able I would include a hyperlink using the previous sentence as the clickable link with a URL reference to

https : //en.wikipedia.org/wiki/Tim_Gunn (spaces after https to make this link not get censored)

to illustrate the way to show that hyperlinks have no real application on modern fashion website. But they would have great utility here inside the answers section. But they also are cause for a securtity concern and may be killed by the moderators
