Can someone explode this level 1 dfd to level 2?
the data flow from seller to login says "log in"
A DB Sellers

Answers

Answer 1

The given Level 1 Data Flow Diagram (DFD) represents a system where data flows from a "Seller" entity to a "Login" process, and there is a "DB Sellers" database involved. To create a Level 2 DFD, we need to expand the "Login" process and show the detailed data flows and processes within it.

Level 2 DFD provides a more detailed view of the processes within Level 1 DFD. In this case, we will expand the "Login" process and illustrate its internal components. The Level 2 DFD may include processes such as user authentication, validation, and database access. Additionally, it will show the data flows between these processes and the "DB Sellers" database.

client/server architecture does involve performance issues that relate to the separation of server-based data and networked clients that must access the data. true or false

Answers

True. In a content loaded client/server architecture, server-based data is separated from networked clients who must access the data. This separation can create performance issues as the network must constantly communicate with the server to access the data, which can result in slower load times and decreased efficiency.

In client/server architecture, there can be performance issues related to the separation of server-based data and networked clients that need to access the data. The performance of the system can be affected by various factors such as network latency, bandwidth limitations, server processing capacity, and database performance. In addition, the overhead of network communication can cause delays and impact the overall performance of the system. Therefore, it is important to design the client/server architecture carefully, considering factors such as load balancing, caching, and data replication, to ensure optimal performance and scalability of the system.

Answers

Answer:

Explanation:

In a password system, the total number of possible passwords is called the **password space**.

The password space represents the total count of unique and valid password combinations that can be generated within a specific password policy or set of criteria. It is determined by considering the available characters, character length, and any additional requirements or restrictions imposed by the system.

For example, if a password system allows the use of lowercase letters, uppercase letters, digits, and special characters, with a minimum length of 8 characters and a maximum length of 16 characters, the password space would encompass all the possible combinations that meet these criteria.

Calculating the exact size of the password space involves considering the number of available characters and the password length. It can be expressed using mathematical notation or by explicitly stating the count of all possible combinations.

Understanding the password space is crucial for evaluating the strength and security of a password system. Systems with larger password spaces provide a greater number of potential combinations, making it more difficult for attackers to guess or crack passwords through brute-force or other password guessing methods.

Organizations and individuals should aim for password systems with large and diverse password spaces to enhance the security of their accounts and sensitive information.

Answer:

C. A musician creates a song using samples of a work and then uses a Creative Commons license to publish the song.

Explanation:

Copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.

A copyright can be defined as an exclusive legal right granted to the owner of a creative work (intellectual property) to perform, print, record, and publish his or her work. Also, the owner is granted the sole right to authorize any other person to use the creative work. The copyright law which protects the sharing and downloading rights of music is known as the Digital Millennium Copyright Act (DMCA).

Furthermore, an intellectual property can be defined as an intangible creation of the human mind, ideas, thoughts or intelligence.

In this scenario, a musician creates a song using samples of a copyrighted work and then uses a Creative Commons license to publish the song. This is an action that is most likely to raise legal or ethical concerns because he didn't get a license from the other musicians who he used their work.

A Creative Commons license is simply a public copyright license that allows for the free distribution of a copyright protected material and it can only be used by the intellectual property owner.

mixture. How much of the 95% mixture will you need to
add to obtain the desired solution?​

Answers

Answer:

375 ml of 95%  is what we need to obtain the desired solution

Explanation:

Solution

Now

450 ml of 40% alcohol mixture +95% mix of x = 65% (450 +x)

Thus

0.40 * 450 +0.95 x = 0.65 (450 + x)

180 + 0.95 x =0.65 (450 +x)

180 +0.95 x = 292.5 + 0.65 x

So,

0.95 x - 0.65 x = 292.5 - 180

= 0.3 x = 112.5

x =112.5/0.3

x= 375 ml

Therefore, we will need 375 ml of 95% solution
