Answer:
Optional product pricing
Explanation:
<em>Optional product pricing</em> occurs when a product is sold for a much lower price but complementary products or accessories are sold separately to generate profit.
A typical example is in the printer category, printer cartridges are sold separately from the printer when the one in the newly purchased printer runs out. The customer is forced to purchase new cartridges that the company benefits from as profits.
Optional product pricing is a strategy to provide less expensive technology while exploiting the frequent use of accessories to make a substantial profit.
Answer:
The following program are written in JAVA Programming Language.
//inherit the Calculator class
public class CalculatorWithMemory extends Calculator {
private double memory = 0.0; //initialize double type variable
public void save() { //define function
memory = accumulator;
}
public void recall() { //define function
accumulator = memory;
}
public void clearMemory() { //define function
memory = 0; //initialize the value
}
public double getMemory() {
return memory; // return the value in "memory" variable
}
}
Explanation:
Here, we inherit the property of the "Calculator" class.
Then, we define the private double type variable "memory" and assign value 0.0.
Then we set the function "save()" inside it we assign the value of "memory" in "accumulator" and close the function.
Then, we define the function "recall()" inside it we assign the value of "accumulator" in "memory" and close the function.
Then we set the function "clearMemory()" inside it we assign "memory" to 0.
After all, we set the double type function "getMemory()" inside we return the value of the "memory".
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.
