The first step when using object-oriented design is to identify all of the categories of inputs that are part of the problem.
What is object-oriented design?Object-oriented design or OOD is a approached method for software design to solving a software problem by process of planning system from interacted objects.
Since, it is a software design to solve software problem based on interacted object, so we must know all object in order to solve a problem especially the object that are part of the problem.
Without identify the input, we don't know the root of problem so we can't solve it. Thus, the first step is to identify all of categories input.

If no two elements in the domain of f correspond to the same element in the range of f, then the function f is 1 -to-1.
In other words, there is exactly one image in the range for each x in the domain. Furthermore, no y in the range has more than one x in the domain as its image.
It is simple to establish if a function is 1 to 1 if the graph of the function is known. Implement the horizontal line test. The function is 1 -to 1 if no horizontal line crosses the graph of the function f at more than one point.
Each x value in a relation must have a unique value for the y value for it to be a function. A collection of ordered pairs is not a function if an x value has more than one y value associated with it, as as in the relation (4, 1), (4, 2), where the x value of 4 has y values of 1 and 2.

add the static keyword in the place of ? if appropriate. public class test { int count; public ? void main(string[] args) { ... } public ? int getcount() { return count; } public ? int factorial(int n) { int result
The common property shared by all objects can be referred to by the static variable (which is not unique for each object).
What does static keyword means?The Java programming language's static keyword designates a member as belonging to the type itself, as opposed to an instance of that type. This indicates that since the static member is shared by all instances of the class, we'll only construct one instance of it.
The common characteristic shared by all objects, which is not specific to each object, can be referred to by the static variable, for instance, the name of the employer for employees, the name of the college for students, etc. When the class is loaded, the static variable only receives one memory allocation in the class area.
Java uses static keywords frequently because of its effective memory management system. The general rule is that you must first build an instance or object of a class in order to access variables or methods contained within it.
The complete question is:
Add the static keyword in the place of ? if appropriate.
public class Test {
int count;
public ? void main(String[] args) {
...
}
public ? int getCount() {
return count;
}
public ? int factorial(int n) {
int result = 1;
for (int i = 1; i <= n; i++)
result *= i;
return result;
}
}
Therefore, the answer is because the factorial method and the main method don't need to reference any instance objects or use any instance methods in the Test class, add static to both of those methods.

An exception that the memory management unit raises whenever a process accesses a memory page without making the necessary preparations is known as a page fault in computing (also known as a hard fault or PF). The virtual address space of the process must be expanded with a mapping before the page can be accessed.
A backing store, like a disk, may also need to be loaded in order to access the actual page contents. The operating system's kernel handles the exception by making the necessary page accessible in the physical memory or preventing an illegal memory access after the MMU detects the page fault.
Any operating system that makes use of virtual memory, such as Windows, macOS, and the Linux kernel, is prone to valid page faults and requires them in order to give programs more memory.

The correct response is d. Annual loss expectancy. The projected financial loss that can be anticipated for an asset due to a risk over the course of a year is known as the annualized loss expectation (ALE).
The annualized loss expectancy can now be calculated by adding the monetary loss from a single incident (SLE) and the likelihood of an incident (ARO) (ALE). The ALE is calculated as follows and represents the annual average loss over a period of several years for a specific asset under threat: ARO x SLE equals ALE. The annual financial impact of a specific risk to the organization is estimated by ALE. This aids in determining how much money the company should spend on countermeasures to lessen the impact or chance of an incidence.The security expert must take into account potential weaknesses before designing any kind of access control system because these give rise to threats.

When do you use while loop instead of a for loop?
To loop exactly 10 times
To make sure a correct number is entered
To loop until a certain condition is reached
To perform number calculations
The option that tells when a person use while loop instead of a for loop is option C:To loop until a certain condition is reached.
What is the while loop?While loops and for loops are both control structures that can be used in programming to repeat a block of code until a certain condition is met.
While loops are used when you want to repeat a block of code an unknown number of times, or as long as a certain condition is true. The syntax for a while loop is:
Copy code
while (condition) {
// code to be executed
In all, a person would use a while loop when you want to repeat a block of code until a certain condition is met, and you would use a for loop when you want to repeat a block of code a specific number of times.

An important part of dashboard design is the placement of charts, graphs, and other visual elements. They should be _____, which means that they are balanced and make good use of available space.
O cohesive
O clean
O consistent
O complete
Answer: A
Dashboard designs should be cohesive, which means that they are balanced and make good use of available space.
A dashboard is a term that can be described as a visual display of the necessary information needed in order to achieve a given objective. Dashboards are important as they influence the behavior of a user and also perform a role to boost retention rates.
An important aspect of dashboard design is ensuring that graphs, charts, and other visual elements are cohesive. Therefore, the term cohesiveness here simply means that they are balanced and make better use of the space available.
A dashboard represents a line of work, thereby balance and cohesion should ideally be interrelated.
A dashboard is configurable and therefore it is possible to select data to include and show graphs or charts for their visualization.

which one of the following logic families is the fastest? static cmos logic clocked cmos logic dynamic logic none of the above
ECL, or emitter-coupled logic, is the name given to the fastest type of logic currently in use. ECL uses a family of BJT transistors.
What is meant by emitter-coupled-logic (ECL)?The fastest logic now in use is typically referred to as emitter-coupled-logic (ECL), a family of BJT transistors. Due to the linked emitters of many transistors, which produce the maximum transmission rate, ECL is the quickest of all the logic families.
Except for specialized applications, CMOS is the common logic family used in ICs. ECL is a substantially quicker architecture than TTL and its related families, with propagation delays of up to 1 ns. It was once a popular choice in computing architecture.
Therefore, the correct answer is option d) none of the above.

Python’s pow function returns the result of raising a number to a given power. Define a function expo that performs this task, and state its computational com- plexity using big-O notation. The first argument of this function is the number, and the second argument is the exponent (nonnegative numbers only). You may use either a loop or a recursive function in your implementation. Caution: do not use Python’s ** operator or pow function in this exercise!
import math
def expo(base,power):
#Result variable
res = 1
#Special cases
if(power==0 and base!=0): return 1
if(power==0 and base==0): return -1
if(base==0 and power!=0): return 0
if(base!=0 and power==1): return base
#Evaluating
if(power>=1):
for i in range(1,int(power)+1):
res*=base
return res
if(power>0 and power<1):
#Natural logarithm implementation and approx. result
#First, determine the McLaurin Series expansion
nominator = power*math.log(base)
res+=nominator
for i in range(2,7):
idx = 1
for j in range(i):
