Janitor and Cashier classes have a print function that is similar.

Which of the following guidelines about the subject line of e-mail messages is most appropriate?
1: Avoid using a subject line unless the e-mail is very important.
2: Use the subject line wisely to let your reader know the main purpose of the e-mail.
3: Try to keep the subject line very short, such as just one or two words.
4: Make sure you provide all the details in the subject line in case the receiver does not have time to read the whole e-mail.
Answers
Answer: 2: Use the subject line wisely to let your reader know the main purpose of the e-mail.
============================================================
Explanation:
The subject line is like the title of a book. You want to give a quick sense of what the email is about, but you also don't want to put the entire contents of the book in the title. The subject line only has so much room. Even less room is available if the reader is checking their email on their mobile device.
Choice 1 is false because subject lines are important. I can't think of a case where you can omit the subject line entirely (ie leave it blank), unless it's a situation where the recipient knows in advance what the topic is about. Though that may be rare.
Choice 3 is false. Yes you want to keep the subject line short, but you also don't want to be cryptic or confusing. If you can get away with using 1 or 2 words, then go ahead and do so. However, you may need more words to convey the topic of the email. Go with what feels right and try to put yourself in the shoes of the person reading your email. Ask yourself "Does this convey the message I want to send?"
Choice 4 is false. As mentioned, you do not want to put the entire email in the subject line. The exception of this rule is that if the email is really really short. For every other case, you should have a fairly short title and then go over the details in the email main body itself.
Answer:
Use the subject line wisely to let your reader know the main purpose of the e-mail.

Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.
Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.
WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.

User-oriented requirements are mostly focused on:
Answers
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.
