Binary search tree: This is seen as O(h), and it is one where h is seen as the height of the said tree.
In terms of Hash table based dictionary: It is one that is not applicable, as it is one where the hash tables do not aid or support any form of finding of any kind in terms of the minimum element.
Lastly in terms of Direct address based dictionary: O(1) is one that is seen as as the minimum element that is it is one that can be directly accessed via the use of its key.

User-oriented requirements are mostly focused on:
User-oriented requirements, also known as user requirements or user needs, are primarily focused on satisfying the needs, expectations, and preferences of the end-users or customers of a product or service.
These requirements play a crucial role in ensuring that the final product or solution meets the intended purpose and provides a positive user experience.
Here are some key points to understand about user-oriented requirements:
1)Understanding User Needs: User-oriented requirements involve identifying and understanding the specific needs, goals, and challenges of the target users.
This includes factors such as usability, functionality, performance, reliability, security, and accessibility.
2)User-Centric Design: User requirements drive the design and development process, emphasizing the importance of designing products and services that align with user expectations.
User-centered design principles and methodologies, such as user research, personas, and user testing, are often employed to gather feedback and iteratively improve the user experience.
3)Clear Communication: User requirements need to be clearly defined and communicated to the development team and stakeholders.
This ensures that everyone involved understands the user's perspective and can work towards meeting their expectations.
4)Prioritization and Trade-offs: User-oriented requirements help prioritize features, functionalities, and design decisions based on user needs.
Trade-offs may be necessary to balance conflicting requirements and constraints while still addressing the most critical user needs.
5)Continuous Feedback and Iteration: User-oriented requirements are not static but evolve throughout the development process.
Regular user feedback and usability testing help identify areas for improvement, allowing for iterative refinements and enhancements.
6)Measuring User Satisfaction: User-oriented requirements are often evaluated by measuring user satisfaction through surveys, interviews, or usage analytics.
User feedback is valuable for validating whether the product or service meets the desired user expectations and identifying areas for further improvement.

Assume that we need to transmit a 1,440 X
900 uncompressed color image (using 16 bits
per pixel) over a computer network in less than
0.01 second. What is the minimal necessary
line speed to meet this goal?
Answer:
The answer is "\(247.19 \ \frac{MB}{sec}\)".
Explanation:
over all pixels \(= 1,440 \times 900\)
\(= 1,296,000\\\\= 1,296 \times 10^3\)
\(time = 0.01 \ sec \\\)
formula of time:
\(time= \frac{bits}{speed} \\\\speed= \frac{bits}{time}\)
\(=\frac{1,296 \times 10^3 \times 16}{0.01}\\\\=20,736 \times 10^5 \ \frac{bytes}{second}\\\\=\frac{20,736 \times 10^5}{8} \ \frac{bytes}{second}\\\\= 2,592 \times 10^5 \ \frac{bytes}{second}\\\\= 247.19 \ \frac{MB}{sec}\)

Mark is unable to connect to the internet or to any of the computers on his network, while nearby computers don’t have this problem. Which three issues could be causing the problem?
slow transmission of data
improper cable installation
faulty software configuration
interference between the signals on cables close to each other
improper connection of a network cable to the jack
Answer:
I. Improper cable installation.
II. Interference between the signals on cables close to each other.
III. Improper connection of a network cable to the jack
Explanation:
The standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. Thus, the standard Internet communications protocols which allow digital computers to transfer (prepare and forward) data over long distances is the TCP/IP suite.
In this scenario, Mark is unable to connect to the internet or to any of the computers on his network, while nearby computers don’t have this problem. Therefore, the three issues which could be causing the problem are;
I. Improper cable installation: this involves not installing the ethernet cable in the correct destination port.
II. Interference between the signals on cables close to each other: interference usually results in the disruption in network signals.
III. Improper connection of a network cable to the jack: the right connectors such as RJ45 should be used.

Use interfaces and inheritance to create a hierarchy of all employees including doctors, nurses, and patients. Then, write the code outline of these classes. You don't have to implement any of the methods or a main method. Just add a simple comment or println statement describing what the method would do.

Explanation:
Kindly check the attached image below to see the step by step explanation to the question above.
Can anyone help me in this question pls?...
a. Draw the hierarchy chart and then plan the logic for a program needed by Hometown Bank. The program determines a monthly checking account fee. Input includes an account balance and the number of times the account was overdrawn. The output is the fee, which is 1 percent of the balance minus 5 dollars for each time the account was overdrawn. Use three modules. The main program declares global variables and calls housekeeping, detail, and end-of-job modules. The housekeeping module prompts for and accepts a balances. The detail module prompts for and accepts the number of overdrafts, computes the fee, and displays the result. The end-of-job module displays the message Thanks for using this program.
b. Revise the banking program so that it runs continuously for any number of accounts. The detail loop executes continuously while the balance entered is not negative; in addition to calculating the fee, it prompts the user for and gets the balance for the next account. The end-of-job module executes after a number less than 0 is entered for the account balance.

Install an eSATA expansion card in the computer to add an extra eSATA port for the customer's external drives.
To fulfill the customer's request of adding an extra eSATA port for external drives, you can install an eSATA expansion card in the computer. This expansion card will provide the necessary connectivity for the customer to connect eSATA devices, such as external hard drives, to the computer.
First, ensure that the computer has an available PCIe slot where the expansion card can be inserted. Open the computer case and locate an empty PCIe slot, typically identified by its size and the number of pins. Carefully align the expansion card with the slot and firmly insert it, ensuring that it is properly seated.
Next, connect the power supply cable of the expansion card, if required. Some expansion cards may require additional power to operate properly, and this is typically provided through a dedicated power connector on the card itself.
Once the card is securely installed, connect the eSATA port cable to the expansion card. The cable should be included with the expansion card or can be purchased separately if needed.
Connect one end of the cable to the eSATA port on the expansion card and the other end to the desired location on the computer case where the customer can easily access it.
After all connections are made, close the computer case, ensuring that it is properly secured. Power on the computer and install any necessary drivers or software for the expansion card, following the instructions provided by the manufacturer.
With the eSATA expansion card installed and configured, the customer will now have an additional eSATA port available on their computer, allowing them to connect external drives and enjoy fast data transfer speeds.
