Answer:
B. Update the UEFI firmware
Explanation:
UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs. It is responsible for waking up the computer hardware components and ensure they are functioning properly.
The old processor was controlled by an older version of the UEFI but to run the new processor, you update the Firmware Interface to enable it communicate with the computer's hardware components.
Answer: TRUE
Explanation: Networking technology is the term used to describe the entire processes through which computer or mobile systems are linked up either through optic fibers,wireless systems in order to enhance effective communication across networks or regions.
OSI (open system interconnection), the earliest models partitions into seven layers and the OSI is known as model that creates partitioning a communication system classing them into abstraction layers.

{
switch (ch)
{
case '+':
case '-':

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 predecessor for the Internet is ARPANET . ARPANET was developed under the direction of the U.S. Advanced Research Projects Agency (ARPA) and first published in 1967.It was <span>designed to facilitate communication between ARPA computer terminals .</span>This network was the first fully operational packet-switching network.
The statement "On the numeric keypad, your pinky types the enter key. " is True. By home keys, the pinky finger is asigned to type in the "enter key". It is a proper practice that makes typing more effiecient. I hope my answer has come to your help. God bless and have a nice day ahead!
