A computer virus is a program that is installed without the permission or knowledge of the computer user.
It is designed to alter the computer's normal operations and can replicate itself to infect other files, programs, or media it can access. Computer viruses are malicious and often spread through infected files, emails, or downloads.
Once inside a computer system, they can cause various damages, such as corrupting data, stealing personal information, or disrupting the computer's functionality.
As they replicate, they can rapidly spread to other devices and networks, making them a significant threat to the security and integrity of computer systems worldwide.
Protecting against viruses requires robust antivirus software and cautious online behavior.

Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int x=5,y=2,z=9;
int min;
// find the smallest value and assign to min
// if x is smallest
if(x < y && x < z)
// assign x to min
min=x;
// if y is smallest
else if(y < z)
// assign y to min
min=y;
// if z is smallest
else
// assign z to min
min=z;
// print the smallest
cout<<"smallest value is:"<<min<<endl;
return 0;
}
Explanation:
Declare and initialize variables x=5,y=2 and z=9.Then check if x is less than y and x is less than z, assign value of x to variable "min" .Else if value of y is less than value of z then smallest value is y, assign value of y to "min".Else z will be the smallest value, assign its value to "min".
Output:
smallest value is:2
Answer:
privilege escalation
When an attacker gains privileges greater than what they already have, it's called privilege escalation. Both vertical (becoming a superuser) and horizontal (getting privileges of a peer) are serious security risks.
If privileges are greater than those already available to the attacker, the result is a privilege escalation. In terms of computer security, privilege escalation means that a user receives privileges they are not entitled to. These privileges can be used to delete files, view private information, or even take control of the system. It can occur in two ways: vertical privilege escalation, also known as becoming the superuser, whereby a user can get rights reserved for a user with higher privileges. Horizontal privilege escalation, on the other hand, is when a user is able to acquire the same privileges as another user. In both cases, it represents a serious security risk.

The answer is false.
An Explicit location is a new concept that Google uses when a searcher is performing a local search and includes the location as well. For instance, instead of searching for “hotel”, the searcher could specify the location and search for Washington Hotel. Searching locations in this way clearly shows that you are looking for something in a specific location. An explicit location is treated as the dominant location of the query and may not be the actual location intent of the query.

Answer:
The answer to this question is given below in the explanation section.
Explanation:
This question is about to tell the best and suitable terms for the given descriptions in the question.
As we know that a computer program is based on sets of instructions. The CPU carries out the processing using the fetch decode and execute cycle.
It is responsible for implementing a sequence of instructions called a computer program that takes input, processes them, and outputs the result based on processing.
A CPU mainly has three components such as control unit, Arithmetic logic unit, and register.
The control unit controls all parts of the computer system. It manages the four basic operations of the Fetch Execute Cycle such as Fetch, Decode, Executes, and Storage.
So the correct terms of this question are:
Fetch: Gets next instruction
Decode: interprets the instruction
Execute: Carries out instruction.
Store: Save results of instruction.
The complete steps are:
Fetchgets the next instruction.
Decode interprets instruction.
Executecarries out instruction.
Store saves the result of the instruction.
The terms that describe each step of the cycle in a computer's processing are as follows:
Fetch: This step "gets the next instruction." It involves retrieving the next instruction from memory to be executed by the processor.
Decode: This step "interprets the instruction." In this phase, the processor decodes the fetched instruction to understand what operation it needs to perform.
Execute: This step "carries out the instruction." Here, the processor executes the decoded instruction, which could involve performing calculations, data manipulation, or other operations.
Store (also known as Write Back): This step "saves the result of instruction." After the execution phase, if the instruction modified data in memory, this step writes back the results of the executed instruction into the appropriate memory location.
These four steps together make up the basic fetch-decode-execute cycle of a computer's central processing unit (CPU). The cycle is repeated for each instruction the computer processes, enabling it to perform tasks and run programs.
