Answer:
Data link layer of OSI model is creating the erroneous segments
Explanation:
The Open System Interconnection (OSI) model is a conceptual framework about how communication occurs between devices over the Internet. It has seven layers, (Physical, Data, Network, Transport, Session, Presentation and Application layer). The purpose of this hierarchical layer system is to understand the structure of communication between devices and do troubleshooting easily if a fault occurs. As in this question, Marry is troubleshooting her company LAN network. She finds out that data segments that the client is encoding are resulting in errors in the encoding. Now the question arises, how she found the cause of the error. The OSI model helps her in understanding the problem.
As you know, the data link layer of the OSI model is responsible for the encoding and decoding of data segments. This layer ensures the reliability of the physical layer, and responsible to provide error-free transfer of data from one node to another on a network. It is also responsible for frame synchronization and flow control. The data link layer is divided into sub-layers:
1. Media Access Control Layer: this layer controls how a computer on the network gains access to the data and transmission permission.
2. Logical Link Control Layer: This layer controls frame synchronization, error checking and flow control.
Therefore, Marry founds data link layer of the OSI model is creating the erroneous segments in encoding.
Answer:
"Option b and Option d" is the correct option for this question.
Explanation:
In the database, datatype belongs to the information storage medium, which can hold a specific type of value. There are several data types, which is used in database like integer, character, series, floating-point and array numbers, and the rules, that give levels of security to information are known as a security constraints. It may be either developed as rules on integrity, mathematical formalism rules or schematic rules, and other choices were wrong which can be described as follows:
- In option a, The asserts, which is in any exchange in a database, should only modify the information, that is effected in acceptable ways is called consistency, that's why it is wrong.
- In option c, The validity and accuracy of the data in the database can not be ensured, that's why it is wrong.

Answer:
I want to take this time to discuss a few expectations and helpful information about how to participate in the weekly online discussions. You can scroll down the page or use the links here to navigate to each section. All Discussions can be found by clicking on the Discussions link located on the left-hand side of the course.
Explanation:
Participation in the discussion forums is critical for maximizing student learning in this course, both because your participation is graded and because it's a chance to engage in a dialogue about course material. In this course, students are required to be a part of an online community of learners who collectively interact, through discussion, to enhance and support the professional performance of each other. Part of the assessment criteria for the course includes evaluating the quality and quantity of your participation in the discussion forum.
The TAS will facilitate student discussions, although they likely will not address every single post. In most cases, they might share a related idea, intervene when the discussion goes off-track, or tie student comments together to help deepen student learning. Remember, if you have a specific question, pose
