Answer:
b. they are located at the intersections of the network of wires and cables that make up the internet.
Explanation:
Given that Router is a computer networking device that operates by transferring data packets between computer networks, while also ensuring traffic organizing tasks on the Internet.
Hence, Routers put packets in the right order after they arrive at their destination by matching the destination IP address of the packet and one of the addresses in the routing table.
Also, Routers check the address on each packet that arrives and decide which way it should go next by ensuring the data packets are summarized for the outgoing interface recorded in the table entry.
Therefore, the correct answer is option B
Based on the above, the type of cable that need to be used by you is option B) Plenum rated cable.
<h3>What is plenum rated cable mean?</h3>
Plenum rated cable is known to be a kind of a cable that tends to have a unique form of insulation that is known to have low smoke and low flame attribute.
Note that the Plenum cable is one that need to be installed in any "air handling" space and as such, Based on the above, the type of cable that need to be used by you is option B) Plenum rated cable.

Each high-level language has its own syntax which is also called rules of the programming language. Therefore, the correct choice is syntax.
High-level languages have a greater level of abstraction from details of the computer. They focus more on the programming logic which is closely associated with human understanding instead of the underlying hardware modules. Each high-level programming language has its own specific set of rules which is known as the syntax of that language.
Syntax of the high-level languages define structure and formation of the statements in the language. In order to write a program in any high-level programming language, proper syntax of that programming language requires to be followed.
If the syntax of the programming language is not followed properly, the compiler will produce errors. In result, required output of the program will not be generated because of the failure of the program execution.

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.
The central processing unit (CPU) is what powers the computer. Any lower-end CPUs will not run a quick-functioning computer very well.
