why has base 2 been accepted and used as the basis for computing?
Answers
Answer:
Binary numbers which are essentially in base 2 has been accepted and used as the basis for computing because they consist of 0s and 1s, which are the only language the computer recognizes and understands.
Explanation:
In Computer science, a bit is a short word for the term binary digit and is primarily the basic (smallest) unit measurement of data or information.
A bit is a logical state which represents a single binary value of either one (1) or zero (0). This ultimately implies that, a single bit in computer science represents a boolean value of;
1. True or ON, which is equal to one (1).
2. False or OFF, which is equal to zero (0).
Machine and assembly are referred to as a low level programming language used in writing software programs or applications with respect to computer hardware and architecture. Machine language is generally written in 0s and 1s, and as such are cryptic in nature, making them unreadable by humans but understandable to computers.
On the other hand, assembly language use commands written in English such as SUB, MOV, ADD, etc.
A binary numbering system represents all numeric values that are to be written in sequences of ones (1s) and zeroes (0s).
Binary numbers which are essentially in base 2 has been accepted and used as the basis for computing because they consist of 0s and 1s, which are the only language the computer recognizes and understands.

counter < num.length() - 1
counter <= num.length()
counter < num.length()
counter > num.length()
counter < num.indexOf(counter)
Answers
The instruction that should replace /* Missing Loop Header */ so that the code segment works as intended is (c) counter < num.length()
LoopsThe program is an illustration of loops (the while loop)
While loops are program statements that are used to perform repeated operations
For the string to return 23456, the while loop body must be repeated as long the counter is less than the length of the string num
Hence, the missing loop header is counter < num.length()

The possibility of someone maliciously shutting down an information system is most directly an element of: a. Availability risk.
Availability risk refers to the potential for an information system to become unavailable or inaccessible to authorized users. This risk can arise from various factors, including intentional attacks or disruptions that aim to disrupt or deny access to the system.
In the context of someone maliciously shutting down an information system, their actions directly impact the availability of the system. By intentionally shutting down the system, they prevent legitimate users from accessing the services or data provided by the system.

A brick has a weight of 23N. The brick is flat and smooth on the side in contact with the floor having measurements ( height= 5cm, length =20cm, width=10cm).
A)Calculate the area of the brick in contact with the floor. Give your answer in cm2.
B)Calculate the pressure of the brick on the floor.
Answers
Answer:
A)Area = 200\(cm^{2}\)
B) Pressure = 0.115 N/\(cm^{2}\)
Explanation:
Assuming that the brick is flat on the floor with its largest face towards the floor and not on its side, then we can calculate the area of that face by multiplying the length by the width like so...
Area = length * width
Area = 20cm * 10cm
Area = 200\(cm^{2}\)
The formula for calculating pressure is force divided by area. Therefore, since we just finished calculating the area and the force is given to us in the question (23N) we can simply plug in these values and solve for the pressure.
Pressure = Force / Area
Pressure = 23N / 200\(cm^{2}\)
Pressure = 0.115 N/\(cm^{2}\)

Answers
The appropriate hypothesis test for determining if engagement scores differ between the old and new ELMS website is the paired t-test.
Which hypothesis test is suitable for comparing engagement scores between the old and new ELMS website?The appropriate hypothesis test in this scenario is the paired t-test. The study aims to compare the engagement scores of a group of 32 students who interact with both the old and new ELMS website, with half of them starting with the old website and the other half starting with the new website.
The paired t-test is suitable when analyzing dependent samples, where each participant is measured under two different conditions or treatments. In this case, the students' engagement scores are paired because they are measured before and after interacting with different versions of the ELMS website.
By using the paired t-test, the researchers can assess whether there is a significant difference in engagement scores within each participant, taking into account the order in which they interacted with the websites. This test allows for controlling the potential variability between individuals, as each participant serves as their own control.

Answers
From a usability point of view, the graphical interface is better than the command-line interface. According to Nielson's 10 usability heuristics, the graphical interface is more user-friendly and offers a better user experience.
The reasons for this are as follows:
Graphical Interface has superior usability: The graphical interface offers a better user experience because it is more visually appealing and easier to use than the command-line interface. The graphical interface is more intuitive and user-friendly because it uses visual cues to guide users through different tasks. This means that users can easily navigate through different screens and interact with different elements without having to memorize complex commands.Command-line Interface requires memorization: The command-line interface is not user-friendly because it requires users to memorize complex commands to interact with the system. This makes it difficult for users who are not familiar with the command-line interface to use the system effectively. The command-line interface is also less visually appealing than the graphical interface, which makes it less attractive to users who value aesthetics and user experience.In conclusion, the graphical interface is better than the command-line interface from a usability point of view because it offers a better user experience, is more visually appealing, and is more intuitive and user-friendly.
