Identify at least two ways computers are used in daily life and share one pro and one con for each
Answer:
There are many ways in which computers are used in daily life. Here are two examples, along with a pro and a con for each:
Personal computers:
Pro: Personal computers allow individuals to perform a wide range of tasks, including word processing, internet browsing, and online communication. They are also an essential tool for education and work.
Con: Personal computers can be expensive to purchase and maintain. They may also be vulnerable to viruses and other types of malware if not properly protected.
Mobile devices:
Pro: Mobile devices, such as smartphones and tablets, allow people to stay connected and access information and services on the go. They can also be used to make phone calls, send text messages, and take photos.
Con: Mobile devices can be addictive and may distract people from their surroundings, leading to problems such as decreased productivity and increased risk of accidents. They may also pose a security risk if lost or stolen, as they often contain sensitive personal information.
Two ways computers are used in daily life are: Online shopping and social media.
What is social media?Social media refers to online platforms and websites that allow users to create, share, and exchange content and information with others.
Two ways computers are used in daily life are:
Online shopping:Pro: Online shopping offers convenience, as you can shop from the comfort of your own home and have items delivered directly to you. It also provides access to a wider variety of products than physical stores might offer.Con: Online shopping can be addictive and lead to overspending. It also has the potential to expose personal and financial information to security risks.Social media:Pro: Social media platforms provide a way to connect with friends and family, meet new people, and share information and experiences. They can also be useful for promoting businesses or social causes.Con: Social media can contribute to anxiety, depression, and other mental health issues. It can also be a source of misinformation and cyberbullying, and it can be a time-waster if not used mindfully.Thus, these are the uses of computer in everyday life.

4. Return the card number, first name, last name, and average late fee of each customer. Name this column as "Fee".
5. Return the authors whose first names are shorter than all last names.
6. Return the first 10 borrowing which late fee is unknown.
How do I write these using Oracle SQL sub selects?
Answer:
To write these queries using Oracle SQL sub selects, the following syntax can be used:
1. Return the card number, first name, last name, and average late fee of each customer. Name this column as "Fee".
SELECT card_number, first_name, last_name, AVG(late_fee) AS "Fee"
FROM customers
GROUP BY card_number, first_name, last_name;
2. Return the authors whose first names are shorter than all last names.
SELECT *
FROM authors
WHERE LENGTH(first_name) < ALL (SELECT LENGTH(last_name) FROM authors);
3. Return the first 10 borrowing which late fee is unknown.
SELECT *
FROM borrowings
WHERE late_fee IS NULL
AND ROWNUM <= 10;
Explanation:
In these queries, sub selects are used to select specific data from a table and use it in the main query. For example, in the second query, a sub select is used to select the length of all last names from the authors table, and this data is then used in the main query to filter the authors whose first names are shorter than all last names. In the third query, a sub select is used to filter the borrowings with unknown late fees, and the main query is used to limit the result to the first 10 rows.

Which of the following terms is the encrypted form of a message that is unreadable except to its intended recipient?
a. plain text
b. encryption algorithm
c. ciphertext
d. steganography
c)Ciphertext is the encrypted form of a message that is unreadable except to its intended recipient.
What is encryption?Encoding data is the process of encryption in cryptography. This technique transforms the information's initial plaintext representation into an alternate version known as ciphertext. Only parties with the proper authorization should be able to convert ciphertext to plaintext and gain access to the original data. Although encryption does not by itself stop interference, it does hinder a potential interceptor from understanding the material.
An encryption technique typically employs a pseudo-random encryption key produced by an algorithm for technical reasons. Without the key, it is feasible to decrypt the message, but doing so requires a lot of computer power and expertise for a well-designed encryption scheme. With the key provided by the sender to recipients but not to unauthorized users, an authorized recipient can quickly decrypt the communication.

a technician is running a network above a dropped ceiling that is also used for ventilation. the cable must be twisted pair and must be capable of gigabit ethernet speeds. which of the following cables should the technician use?
A technician is managing a network above a ventilation- and dropped-ceiling system.
Twisted pair and gigabit capabilities on the cable are requirements. Vertical wiring or cabling are other names for the backbone wiring. It offers connectivity between entrance amenities, equipment rooms, and telecommunication rooms. Fiber optic cabling is immune to electromagnetic interference and enables for longer cable distances without the need for a repeater than other types of cabling. However, it is more expensive, and installation calls for specialised knowledge and tools. CMR cable should be used when extending cable across vertical shafts or risers between floors.
