The program to define a method that computes the positive difference between the areas of two rectangles is found in the attached image.

The program defines a class Rectangle with a constructor, and a static method areaDiff. The static method areaDiff takes two rectangles (rect1 and rect2) and returns the positive difference between their areas.

The formula used by areaDiff is:

\(|(rect1.width \times rect1.height)-(rect2.width \times rect2.height)|\)

where

\(rect1,rect2=\text{the two rectangles}\\(rect.width\times rect.height)\text{ calculates the area of a rectangle object}\\|x|=\text{the absolute value function}\)

True, the initial value of a reference to non-const must be an lvalue.

In C++, a reference is an alias for a variable, which means that it refers to the same memory location as the variable it is referencing.

When creating a reference, it is important to note that the initial value of the reference must be an lvalue, which means it must refer to a memory location that can be accessed and modified.

If the initial value is not an lvalue, then the program will not compile and an error message will be displayed. This rule does not apply to references to const, as they do not allow modification of the referenced variable. So, in summary, when creating a reference to non-const in C++, the initial value must be an lvalue.

In this scenario, the loopback address for the Wrk2 computer is 127.0.0.1. It is used for local network testing and communication within the device itself.

The loopback address for the Wrk2 computer in the given scenario is 127.0.0.1.

The loopback address is a special IP address used to test network connectivity on a local machine without actually sending data over a physical network. It allows a device to communicate with itself.

In IPv4, the loopback address is defined as 127.0.0.1 and it is reserved for this purpose. When a device sends data to the loopback address, it is looped back to the device itself without going out to the network.

In the given scenario, the Wrk2 computer has been assigned the IP address 192.168.1.55. This IP address belongs to the local network, and it can be used to communicate with other devices on the same network. However, if the Wrk2 computer wants to test its own network connectivity, it can use the loopback address 127.0.0.1.

For example, if the Wrk2 computer wants to check if its network stack is functioning properly, it can ping the loopback address. By sending a ping to 127.0.0.1, the Wrk2 computer will receive a response from itself, confirming that its network stack is working correctly.

Answer: Cache memory

Explanation: trust me I majored in Computer Science

Cache memory is a small, high-speed, high-cost memory that servers as a buffer for frequently accessed data.

It is a small amount of faster, more expensive memory that is used to speed up data that has been accessed recently or frequently. Reserved information is put away briefly in an open stockpiling media that is neighborhood to the store client and separate from the principal stockpiling. Reserve is ordinarily utilized by the focal handling unit (central processor), applications, internet browsers and working frameworks.

Because bulk or main storage cannot meet the demands of customers, cache is utilized. Cache speeds up data access, reduces latency, and enhances input/output (I/O) performance. Since practically all application jobs rely upon I/O activities, the storing system further develops application execution.

The working of Cache memory.

A cache client first checks the cache before attempting to access data. A cache hit occurs when the data is discovered there. The cache hit rate or ratio is the percentage of attempts that result in a cache hit.

A cache miss is when requested data that is not present in the cache is copied into the cache from main memory. The caching algorithm, cache protocols, and system policies that are in use all have an impact on how this is carried out and what data is removed from the cache to make room for the new data.
