Sleep mode (or suspend to RAM) is a low power mode for electronic devices such as computers, televisions, and remote controlled devices. These modes save significantly on electrical consumption compared to leaving a device fully on and, upon resume, allow the user to avoid having to reissue instructions or to wait for a machine to reboot. Many devices signify this power mode with a pulsed or red colored LED power light
Hibernation Edit
Main article: Hibernation (computing)
Hibernation, also called Suspend to Disk on Linux, saves all computer operational data on the fixed disk before turning the computer off completely. On switching the computer back on, the computer is restored to its state prior to hibernation, with all programs and files open, and unsaved data intact. In contrast with standby mode, hibernation mode saves the computer's state on the hard disk, which requires no power to maintain, whereas standby mode saves the computer's state in RAM, which requires a small amount of power to maintain.
Hybrid sleep Edit
Sleep mode and hibernation can be combined: the contents of RAM are first copied to non-volatile storage like for regular hibernation, but then, instead of powering down, the computer enters sleep mode. This approach combines the benefits of sleep mode and hibernation: The machine can resume instantaneously, but it can also be powered down completely (e.g. due to loss of power) without loss of data, because it is already effectively in a state of hibernation. This mode is called "hybrid sleep" in Microsoft Windows other than Windows XP.
A hybrid mode is supported by some portable Apple Macintosh computers,[1] compatible hardware running Microsoft Windows Vista or newer, as well as Linux distributions running kernel 3.6 or newer.
ACPI Edit
ACPI (Advanced Configuration and Power Interface) is the current standard for power management, superseding APM (Advanced Power Management) and providing the backbone for sleep and hibernation on modern computers. Sleep mode corresponds to ACPI mode S3. When a non-ACPI device is plugged in, Windows will sometimes disable stand-by functionality for the whole operating system. Without ACPI functionality, as seen on older hardware, sleep mode is usually restricted to turning off the monitor and spinning down the hard drive.
Answer:
See explaination
Explanation:
#include <fstream>
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
// Fill in the code to define payfile as an input file
ifstream payfile;
float gross;
float net;
float hours;
float payRate;
float stateTax;
float fedTax;
cout << fixed << setprecision(2) << showpoint;
// Fill in the code to open payfile and attach it to the physical file
// named payroll.dat
payfile.open("payroll.dat");
// Fill in code to write a conditional statement to check if payfile
// does not exist.
if(!payfile)
{
cout << "Error opening file. \n";
cout << "It may not exist where indicated" << endl;
return 1;
}
ofstream outfile("pay.out");
cout << "Payrate Hours Gross Pay Net Pay"
<< endl << endl;
outfile << "Payrate Hours Gross Pay Net Pay"
<< endl << endl;
// Fill in code to prime the read for the payfile file.
payfile >> hours;
// Fill in code to write a loop condition to run while payfile has more
// data to process.
while(!payfile.eof())
{
payfile >> payRate >> stateTax >> fedTax;
gross = payRate * hours;
net = gross - (gross * stateTax) - (gross * fedTax);
cout << payRate << setw(15) << hours << setw(12) << gross
<< setw(12) << net << endl;
outfile << payRate << setw(15) << hours << setw(12) << gross
<< setw(12) << net << endl;
payfile >> hours ;// Fill in the code to finish this with the appropriate
// variable to be input
}
payfile.close();
outfile.close();
return 0;
}
Answer:
The correct option is D: Control Bus
Explanation:
A control bus is usually used by the Central Processing Unit to communicate with all the devices that are connected or contained within a computer. This connections are usually done via physical connections such as printed circuits or cables. It is also called a Computer bus and helps in coordinating activities between the connected devices.
Explanation:
The output of this program is 5 7, because the first time bruce is printed, his value is 5, and the second time, his value is 7. The comma at the end of the first print statement suppresses the newline after the output, which is why both outputs appear on the same line.
Here is what multiple assignment looks like in a state diagram:

With multiple assignment it is especially important to distinguish between an assignment operation and a statement of equality. Because Python uses the equal sign (=) for assignment, it is tempting to interpret a statement like a = b as a statement of equality. It is not!
First, equality is symmetric and assignment is not. For example, in mathematics, if a = 7 then 7 = a. But in Python, the statement a = 7 is legal and 7 = a is not.
Furthermore, in mathematics, a statement of equality is always true. If a = b now, then a will always equal b. In Python, an assignment statement can make two variables equal, but they don’t have to stay that way:
a = 5
