Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.
Explanation:
Some examples are:
call by value
#include <stdio.h>
void swap(int, int);
int main()
{ int a = 10, b= 20;
swap(a, b);
printf("a: %d, b: %d\n", a, b);
}
void swap(int c, int d)
{
int t;
t = c; c = d; d = t;
}
OUTPUT
a: 10, b: 20
The value of a and b remain unchanged as the values are local
//call by reference
#include <stdio.h>
void swap(int*, int*);
int main()
{
int a = 10, b = 20;
swap(&a, &b); //passing the address
printf("a: %d, b: %d\n", a, b);
}
void swap(int *c, int *d)
{
int t;
t = *c; *c = *d; *d = t;
}
OUTPUT
a: 20, b: 10
due to dereferencing by the pointer the value can be changed which is call by reference

Answer:
Worm malware
Explanation:
The worm operates destructively as it replicates itself and keeps spreading within a computer or network. It takes advantage of software and security vulnerabilities.
Once a computer or network is infected, worms replicate themselves, therefore using up the computer and network resources. Among others, one of the major missions of worms is to create a backdoor into a network, to be able to enable the attacker to carry out a more devastating attack.
Since worms take advantage of weak security in the Operating system, it is very important to constantly update the security features of the Operating system. Users must be careful of the emails they open and attachments they download.
