Before upgrading the hard drive and video card of his computer, Jayden should check the A. PSU (power supply unit).
What does the PSU do ?The PSU is responsible for supplying power to all the components of a computer, and a more powerful video card or hard drive may require more wattage than the current PSU can provide.
Checking the CPU (central processing unit) may also be important, as a new video card or hard drive may put more strain on the CPU and cause performance issues if it is not powerful enough. However, the PSU should be the first consideration when upgrading components that require more power.

How should the security for the database be different than security for the rest of the system? Does it make a difference for web-based data designs? If so, how?
The security for the database should be more stringent than the security for the rest of the system, as it contains the critical information that needs to be protected.
How should the security of the database be designed ?The database security should be designed to ensure the confidentiality, integrity, and availability of the data. This means that access to the database should be limited to authorized users and activities should be audited to prevent unauthorized access or modifications.
For web-based data designs, the security of the database is even more critical, as the data is accessed over the internet and is therefore more vulnerable to attacks. Web-based data designs need to incorporate additional security measures such as user authentication, access controls, firewalls, intrusion detection, and prevention systems to protect the database from cyber threats.

Explain the societal implication of computers on society in particular privacies and
quality of life
Computers have had a profound impact on society, particularly in the areas of privacy and quality of life. While computers have made many aspects of our lives easier and more convenient, they have also introduced new challenges and concerns.
One of the biggest societal implications of computers is the issue of privacy. As computers have become more ubiquitous and more connected, the amount of personal information that is being collected and shared has increased significantly. This has raised concerns about who has access to our data and how it is being used. There is also a risk of identity theft and other types of cybercrime, which can have serious consequences for individuals and society as a whole.
Another important societal implication of computers is their impact on quality of life. On the one hand, computers have made many aspects of our lives easier and more convenient. For example, we can now work remotely, shop online, and connect with friends and family from anywhere in the world. However, there is also concern that computers and technology are making us more isolated and less connected to each other. Some argue that social media and other digital technologies have made it more difficult for people to form meaningful relationships and engage in face-to-face communication.
Additionally, computers have also had an impact on the job market. While computers and automation have made many tasks more efficient and cost-effective, they have also led to job displacement and the need for workers to constantly update their skills in order to remain competitive. This can lead to economic and social inequality, particularly for those who are less able to adapt to new technologies.
In summary, computers have had a significant impact on society, both positive and negative. While they have made many aspects of our lives easier and more convenient, they have also introduced new challenges and concerns, particularly with regard to privacy and quality of life. It is important for individuals and society as a whole to carefully consider the implications of new technologies and work to mitigate any negative consequences.
A researcher investigated whether job applicants with popular (i.e. common) names are viewed more favorably than equally qualified applicants with less popular (i.e. uncommon) names. Participants in one group read resumes of job applicants with popular (i.e. common) names, while participants in the other group read the same resumes of the same job applicants but with unpopular (i.e. uncommon) names. The results showed that the differences in the evaluations of the applicants by the two groups were not significant at the .001 level
The study looked into whether job applicants with well-known names would do better than those with less well-known names who were similarly qualified. At a.001 level, the results revealed no significant differences in judgements.

Write and execute the command to retrieve the office number, property ID, and monthly rent for every property in the SMALL_PROPERTY view with a monthly rent of $1150 or more
Assuming the database has a SMALL_PROPERTY view with columns "office_number", "property_id", and "monthly_rent", and you want to retrieve the office number, property ID, and monthly rent for properties with a monthly rent of $1150 or more, you could use the following SQL query:
sql
SELECT office_number, property_id, monthly_rent
FROM SMALL_PROPERTY
WHERE monthly_rent >= 1150;
What is the command?The above query uses the SELECT statement to specify the columns you want to retrieve from the SMALL_PROPERTY view, and the WHERE clause to filter the results based on the condition that the monthly_rent is greater than or equal to $1150.
Note: This query assumes that the SMALL_PROPERTY view and the relevant table(s) are already defined in the database, and the appropriate permissions are granted to the user executing the query. The actual query may vary depending on your specific database management system and schema design. It's always recommended to consult the documentation and guidelines of your database management system for accurate syntax and usage.
