QUESTION 25
Why does it make sense to have error detection codes at the link layer in addition to the checksums at the transport layer?
A. Link layer error detection codes, can themselves have bit errors, and having a second layer of bit error checking can help lessen the impact of this B. Link layer error detection codes capture bit errors in the data payload whereas transport layer checksums only cover the TCP/UDP header fields
C. Link layer bit errors can be corrected faster via a retranmission across the previous link edge whereas a TCP retransmission would have to be from source
host to destination.
It does not make sense. In fact, this is a redundancy that should always be removed (either check for bit errors in the D. link layer or in the transport layer, but
no need for both).

When working with circuits , it is important to understand the different components and their functions. You should also be familiar with circuit symbols and how to read circuit diagrams.

Data tables are often used to organize and analyze data collected during experiments or observations. They typically include columns for variables and rows for data points.

When answering questions based on a circuit and data table, it is important to carefully review the information provided and identify any patterns or relationships. You may need to perform calculations or make comparisons between different data points to fully understand the circuit and its behavior.

In general, working with circuits and data tables requires attention to detail and strong analytical skills. It can be helpful to review examples and practice problems to improve your understanding and proficiency in these areas.

Explanation:

Rlogin is a login protocol used for remote login sessions but lacks security features. It is less secure than SSH and Telnet, which provide encryption and authentication for secure remote access.

Rlogin, also known as Remote Login, is a login protocol used in TCP/IP networking environments to establish a remote login session on a remote host. It allows users to log in and interact with a remote system as if they were physically present at the machine. Rlogin operates on port 513 and relies on the Telnet protocol for communication. It provides basic functionality for remote login, terminal emulation, and command execution. However, Rlogin lacks strong security measures, such as encryption, authentication, and data integrity checks, making it vulnerable to eavesdropping and unauthorized access.

It also does not support secure file transfer. In comparison, Telnet is a general-purpose remote terminal protocol that allows users to establish remote sessions on other hosts. It is similar to Rlogin in terms of functionality and security vulnerabilities. Both Telnet and Rlogin transmit data in plain text, making them susceptible to network eavesdropping and unauthorized interception of sensitive information.

The Entity-Relationship Model (ER Model) is a data model that is used to represent the conceptual schema of a system. It describes the entities, attributes, and relationships between entities in a system.

The ER Model is widely used in database design because it helps to provide a unified view of data in an organization. The ER Model consists of three components: Entities, attributes, and relationships. An entity is anything that is recognizable and unique within a system. An attribute is a characteristic of an entity. It describes a particular aspect of an entity that is of interest to the organization. Relationships describe the associations between entities. They provide a means of capturing the way in which entities relate to each other.

The ER Model is particularly useful because it allows organizations to create a unified view of data. This means that data is consistent and integrated across all systems in the organization. It is also useful because it provides a graphical representation of the data, which can be easily understood by stakeholders. This makes it easier to communicate and share information about the data within the organization.

Vulnerability assessment can be defined as a systematic analysis and review of any form of security weakness in an information system (IS).

Hence, vulnerability assessment is used to determine if an information system (IS) is susceptible (prone) to attacks from users within and outside the network.

On a related note, wireless vulnerability assessment involves the analysis and review of a wireless network to verify its level of security.

Hence, it begins with planning and scheduling of the assessment of the organization's networks using every possible approach to penetration testing, at regular intervals.
