Write a short essay (roughly 500 words) about some topic related to computing
technology or the Internet that interests you and has social or ethical implications. Describe the background; then identify the issues, problems, or questions that you think are important.
The rise of artificial intelligence (AI) raises important social and ethical concerns including potential job loss, bias in algorithms, military applications, privacy, accountability, and impact on society.
How does AI raise social and ethical concerns?One of the most significant developments in computing technology in recent years is the rise of artificial intelligence (AI).
AI has the potential to revolutionize many fields, from healthcare to transportation, One of the most pressing issues facing the computing technology industry today is the growing problem of electronic waste, or e-waste.
E-waste refers to any electronic device that is no longer useful or functional and is discarded, often ending up in landfills or being exported to developing countries.
This issue has significant social and ethical implications, as well as environmental consequences.
Background:
As technology continues to advance, the average lifespan of electronic devices decreases, resulting in an increasing amount of e-waste. According to a report by the United Nations, the world generated 53.6 million metric tones of e-waste in 2019 alone. This is equivalent to throwing away more than 4,500 Eiffel Towers every year. E-waste contains a range of hazardous materials, including lead, mercury, and cadmium, which can pollute the environment and pose health risks to humans.Issues:
The first issue with e-waste is the environmental impact. When electronic devices are not disposed of properly, they often end up in landfills or are incinerated, releasing harmful chemicals and toxins into the air, water, and soil. This pollution can have serious consequences for both human health and the environment, including an increased risk of cancer, respiratory problems, and other health issues.The second issue is the social and ethical implications of e-waste. When e-waste is exported to developing countries, it can contribute to unsafe and exploitative working conditions for those who handle the waste. Workers in these countries may be exposed to hazardous chemicals and toxins while disassembling and processing electronic devices, leading to health problems and even death.Another ethical issue with e-waste is the problem of planned obsolescence. This refers to the practice of designing products with a limited lifespan, often forcing consumers to replace them sooner than necessary.Companies may do this intentionally to boost sales, which can contribute to the growing e-waste problem.Solutions:
One solution to the e-waste problem is the development of more sustainable and eco-friendly products. This would involve designing devices that are more durable and repairable, with components that can be easily replaced or upgraded. Companies could also use more sustainable materials in their products, reducing the need for mining and reducing environmental impact.Another solution is to promote responsible disposal and recycling of electronic devices. This could involve implementing e-waste collection programs in communities, where individuals can drop off their devices for proper disposal or recycling. Companies could also be required to take back and recycle their products at the end of their useful life.Education and awareness campaigns are also crucial in addressing the e-waste problem. Consumers need to be educated on the importance of responsible disposal and recycling, as well as the impact of their purchasing decisions on the environment and society. This could include providing more information on product lifespans, recycling options, and the environmental impact of electronic devices.Conclusion:
In conclusion, e-waste is a significant issue facing the computing technology industry, with serious social, ethical, and environmental implications.
Collaborative effort needed from consumers, companies, and governmentsFocus on sustainable practices to reduce e-waste and ensure a more sustainable future.Learn more about artificial intelligence

A large online social networking company has recently discovered that it may have a problem with a number of accounts that are spreading false information through the site. The company has a collection of n accounts that they have been monitoring over the last several months, suspecting them of being used for such activity. Each account has the following data associated with it: a user id, some possibly fraudulent information (such as the name, etc. ), and a unique encrypted number generated by the site when the account was created. A user can have more than one account on the site. The company will not disclose the identity of the account holders directly without a subpoena, but will tell if two accounts belong to the same user.
Required:
a. The government agency’s question is the following: among the collection of n accounts, is there a set of more than n/2 of them that are all associated with the same user? Assume that the only feasible operation the government investigators can do with the accounts is to choose two of them and ask the company if they belong to the same user (and the company people get more and more reluctant to answer each time).
b. Show how to decide the answer to the agency’s question with only O(nlog n) requests to the social networking company
a. The government agency's question is whether there is a set of more than n/2 accounts among the collection of n accounts that all belong to the same user.
b. To answer the agency's question with O(nlog n) requests to the social networking company, we can use a divide-and-conquer algorithm. We first divide the set of accounts into two halves and recursively check whether there is a set of more than n/2 accounts that belong to the same user in each half.
If such a set exists in one half, we return it. Otherwise, we make n/2 requests to check whether accounts from one half belong to the same user as accounts from the other half.
If we find a set of more than n/2 accounts that belong to the same user, we return it. The algorithm terminates when the size of the set is 1. This algorithm requires only O(nlog n) requests to the company, which is more efficient than checking all possible pairs of accounts.

Alice and bob wish to securely communicate (ensure confidentiality) using the public key (asymmetric key) system. what's the minimum number of keys they would need added together (i.e. total number of keys needed for alice and bob combined)
Alice and Bob would need a total of two keys to securely communicate using the public key (asymmetric key) system. This system involves two different keys, a public key, and a private key. The public key is used to encrypt messages and can be shared with anyone, while the private key is kept secret and is used to decrypt messages.
Alice would need to generate a pair of keys, consisting of a public key and a private key. She would then share her public key with Bob, who would use it to encrypt messages to Alice. Alice would use her private key to decrypt the messages.
Similarly, Bob would need to generate his own pair of keys and share his public key with Alice. Alice would use Bob's public key to encrypt messages to him, and Bob would use his private key to decrypt them.
Therefore, the minimum number of keys Alice and Bob would need to be added together is two. It is important to note that the security of the system relies on the private keys being kept secret, as anyone who possesses the private key can decrypt messages meant for that person.

Dan and daniel wish to communicate with each other using a secret key. which algorithm can they use to have a shared secret key in a secure manner
Dan and Daniel can use the Diffie-Hellman key exchange algorithm to securely generate a shared secret key that can be used for secure communication.
The Diffie-Hellman key exchange algorithm is a public-key cryptography algorithm that allows two parties to securely establish a shared secret key over an insecure communication channel. The algorithm works by allowing each party to generate a public-private key pair, with the public keys exchanged between the parties. Using these public keys, each party can then generate a shared secret key without ever transmitting the key itself over the insecure channel.
The security of the Diffie-Hellman key exchange algorithm is based on the difficulty of computing discrete logarithms in finite fields. Essentially, this means that it is computationally infeasible to determine the private key used to generate a public key without knowing the prime numbers and the original public key used in the algorithm. As such, the algorithm provides a secure method for two parties to generate a shared secret key without exposing it to potential attackers.

Consider a database containing personnel information, including names, addresses, and salaries of employees. Individually, the name, address, and salary information is available to a subordinate role, such as Clerk, but the association of names and salaries is restricted to a superior role, such as Administrator.
1. With this information, how could you construct your database and tables? Design your database and draw a database schema first.
2. Suppose that administrators wants to add a new attribute, employee start date, which is not sensitive. Where would it be? Consider not comprimising the relationship between employee and salary. Draw your new schema
To construct a database for personnel information, we can create three tables: "Employees," "Addresses," and "Salaries."
The employee start date can be added to the "Employees" table as a new column, as it is not sensitive information.
Explanation:
To design a database for personnel information, we can create three tables: "Employees," "Addresses," and "Salaries." The "Employees" table contains the name and employee ID of each employee. The "Addresses" table contains the employee ID and their corresponding address. The "Salaries" table contains the employee ID and their corresponding salary. The "Employees" table is accessible by both Clerks and Administrators, while the "Addresses" and "Salaries" tables are accessible only by Clerks and Administrators, respectively. The database schema for this design would consist of three tables with the employee ID serving as the primary key and foreign keys linking the tables.
The employee start date can be added to the "Employees" table as a new column, as it is not sensitive information. This column would not compromise the relationship between employee and salary, as the salary information is still only accessible by Administrators through the "Salaries" table. The new database schema would include the "Employees" table with the added column for employee start date.

O is 1 (for one clock cycle, from positive edge to positive edge) if the last three bits read are 001, with 1 as the most recent bit
To design a circuit that satisfies the given specifications, we can use a shift register and a combinational logic circuit. The shift register will store the last three bits read, and the combinational logic circuit will check if the bits match the pattern 001.
The circuit will have two inputs: clk and X. The clk input is a clock signal that triggers the circuit to sample the X input at every rising edge. The X input is the binary input that may change every clock cycle, and the change happens at the falling edge. To detect the falling edge of the clock signal, we can use a flip-flop.
At every rising edge of the clock, the circuit will sample the X input and store the bit in a shift register. The shift register will have three stages, and it will shift the bits to the right at every clock cycle. The most recent bit will be stored in the first stage, and the oldest bit will be stored in the third stage.
The combinational logic circuit will check if the three bits stored in the shift register match the pattern 001. If the bits match the pattern, the output O will be set to 1 for one clock cycle, from positive edge to positive edge. Otherwise, the output will be set to 0.
To implement the combinational logic circuit, we can use a series of AND gates and inverters. We can connect the output of the shift register to the inputs of the AND gates, and use the outputs of the gates to check if the bits match the pattern. If the three bits match the pattern, the output of the last AND gate will be 1, and we can use an inverter to generate the output O.

After information system has been implemented discuss how management assess how successful is has been in achieving it's business goals
Once an information system has been implemented, management will need to assess its success in achieving the business goals that were established prior to implementation.
How management assesses the success of an implemented information system?
1. Identify the business goals: Start by clearly defining the specific business goals that the information system was intended to achieve. These goals can be related to increasing efficiency, improving decision-making, or enhancing communication within the organization.
2. Establish Key Performance Indicators (KPIs): Determine the KPIs that directly measure the performance of the information system in relation to the identified business goals. KPIs can be quantitative (e.g., cost reduction, time saved) or qualitative (e.g., user satisfaction, ease of use).
3. Collect data: Collect data on the KPIs by monitoring the performance of the information system, conducting surveys, or gathering feedback from employees and stakeholders.
4. Analyze the data: Compare the actual performance of the information system against the established KPIs to evaluate how well it has been meeting the business goals.
5. Review and adjust: If the analysis shows that the information system is not meeting its business goals, management can identify areas for improvement and make necessary adjustments. This may involve modifying system features, providing additional training, or addressing other issues that have been identified.
In conclusion, after implementing an information system, management can assess its success in achieving business goals by identifying specific goals, establishing KPIs, collecting and analyzing data, and making adjustments as needed.

suppose a large warehouse has 20% of the items (fast items) contributing to 80% of the movement in and out, and the other 80% of the items (slow items) contributing to the remaining 20% of the movement. which storage policy would you recommend? (check all answers) group of answer choices class-based storage policy for fast and random policy storage for slow dedicated storage policy for fast and slow class-based storage policy for fast and slow random storage policy for fast and random policy storage for slow dedicated storage policy for fast and random policy storage for slow
Based on the given information, a recommended storage policy would be a class-based storage policy for fast items and a random storage policy for slow items.
Since the fast items are responsible for 80% of the movement in and out of the warehouse, it would be beneficial to have them stored together in a designated area, such as a specific aisle or section of the warehouse. This would allow for faster and more efficient picking and replenishment processes, as well as potentially reducing the risk of errors or misplacements.
On the other hand, since the slow items only contribute to 20% of the movement, a random storage policy would be more suitable for them. This means that they can be stored in any available location throughout the warehouse, without being grouped together based on any specific criteria. This allows for more flexible use of the warehouse space and can potentially reduce the amount of time spent searching for specific items.
Alternatively, a dedicated storage policy for fast and slow items could also be considered. This would involve having separate areas or even separate warehouses for the two types of items. However, this approach may not be as cost-effective or practical for all warehouses.
Overall, the storage policy chosen should aim to optimize the efficiency and productivity of the warehouse, while also taking into account the specific characteristics and demands of the items being stored.
