Answer:
B. Binary Code
Explanation:
Binary code is the base-2 system used by computers to represent data. Binary code consists of 0's and 1's which can be used to represent states such as on or off; go or no-go and more.
Answer:
static int checkSymbol(char ch)
{
switch (ch)
{
case '+':
case '-':
return 1;
case '*':
case '/':
return 2;
case '^':
return 3;
}
return -1;
}
static String convertInfixToPostfix(String expression)
{
String calculation = new String("");
Stack<Character> operands = new Stack<>();
Stack<Character> operators = new Stack<>();
for (int i = 0; i<expression.length(); ++i)
{
char c = expression.charAt(i);
if (Character.isLetterOrDigit(c))
operands.push(c);
else if (c == '(')
operators.push(c);
else if (c == ')')
{
while (!operators.isEmpty() && operators.peek() != '(')
operands.push(operators.pop());
if (!operators.isEmpty() && operators.peek() != '(')
return NULL;
else
operators.pop();
}
else
{
while (!operators.isEmpty() && checkSymbol(c) <= checkSymbol(operators.peek()))
operands.push(operators.pop());
operators.push(c);
}
}
while (!operators.isEmpty())
operands.push(operators.pop());
while (!operands.isEmpty())
calculation+=operands.pop();
calculation=calculation.reverse();
return calculation;
}
Explanation:
- Create the checkSymbol function to see what symbol is being passed to the stack.
- Create the convertInfixToPostfix function that keeps track of the operands and the operators stack.
- Use conditional statements to check whether the character being passed is a letter, digit, symbol or a bracket.
- While the operators is not empty, keep pushing the character to the operators stack.
- At last reverse and return the calculation which has all the results.
Answer:
This type of attack is called Malvertising
Explanation:
Malvertising (Malware Advertising) is a term in computer security that refers to the act of spreading computer malware through online advertisements. It is done by injecting malicious code into genuine online advertisement platforms or malicious webpages that appear as though they are genuine and from reputable third-party advertisers. While it is quite a new concept it is difficult to combact because content for advertisement can be placed in genuine and reputable websites that users trust.
Answer:
ISO 27002
Explanation:
The acronym ISO stand for The International Organization for Standardization. its a non governmental body that is responsible for setting standards guide internationally.
while NIST stand for National Institute of Standards and technology and it is also a body that is responsible for setting up standard guide in the US..
ISO 27002 is a standard code for implementing information security management systems. while ISO 27017 is for cloud security. NIST 800-12 is a general security and NIST 800-14 is for policy development. thus option A is correct.
Note :
All code preceded by ISO is from The International Organization for Standardization and are international standard. while those preceded by NIST is from National Institute of Standards and technology and are not international standard.
Answer:
Equity and accessibility are the two simplest issues in online education.
Explanation:
This is because neither of these issues have to do with anything that has to do with ethics. They are not the least essential issues, because if you can't access online education you just can't learn online. These are the two simplest issues, because if you can't access online education, you just can't learn that way.
