Explanation:
What happens is that the security of a company's information and data system can be affected by its people because it is the organization's own employees who can leak sensitive information, for their own benefit or for the benefit of others. That is why it is extremely relevant that organizations should limit the level of access that each user has to their information system.
Adequate training in the use of these systems is essential for employees to use it properly, to correct system failures, and for top management to have adequate knowledge in the preparation of system security plans.
It is the security policies that will prevent unauthorized access and greater control over the security of important data and information, so it is important that any company with a data information system keeps itself up to date with the software and implements necessary security resources, in a way maintain security and always update and analyze the operation of technological equipment.
Oh depending on the make (not familiar with that model) you could run a custom rom on it! A good cooked rom could bring new life to your old device just read the documentation and look into it more; you could also try seeing a maintenance specialist but for a phone there are limited solutions unfortunately.
Answer:
C++ code is explained below
Explanation:
a- C++ code:
#include<iostream>
using namespace std;
#include <string.h>
int firstOccurence(char *s,char c) //recursive function
{
static int i;
if(!s[i])
{
return -1;
}
else
{
if(s[i]==c)
return i;
i++;
firstOccurence(s,c);
} }
int main()
{
char s[1000],c;
int n;
printf("Enter the string : "); //tales input
gets(s);
printf("Enter character to be searched: "); //takes input a character to be searched
c=getchar();
n=firstOccurence(s,c); //call function
if(n>-1)
printf("character %c is first occurrence at location:%d ",c,n);
else
printf("character is not in the string ");
return 0;
}
b- C++ Code- This program takes a string and display sum of all characters in a string.
#include<iostream>
using namespace std;
int sumAscii(string s) //recursive function
{
int sum = 0;
if(s.length() == 0)
{
exit(0);
}
for (unsigned int i = 0; i < s.size(); i++)
{
sum += s[i];
}
return sum;
}
int main () //main function
{
cout << "This word adds up to " << sumAscii("CAT") << " in ASCII " << endl;
return 0;
}

Explanation:
Hamming code is a set of error-correction codes that can be used to detect and correct the errors that can occur when the data is moved or stored from the sender to the receiver. It is technique developed by R.W. Hamming for error correction.
