In option b, It is a part of the philosophy of education, that's why it is not correct.Option c, Potential is used in the education section, that's why it is wrong.Option d, It is used in a single source computer, that's why it is wrong.The main disadvantage of using this device is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.?
Answer:
Hub
Explanation:
Hub is used to connect devices in a network. It is also called a dumb device because it broadcasts the signals or messages on any of its ports to all other ports. For example a message has to be sent to a computer. Lets name that computer H. Hub will send that message to all connected ports on the hub not just considering that specific port of computer H. So hub is an unintelligent device which is not able to distinguish between devices and sends a messages to every port irrespective of which the destination host is. Now when the destination computer H responds to that message this too goes to all other ports on hub.This has a negative effect on network's performance as it might result in collisions between data packets.The bandwidth of hub is shared by all the devices connected to it. When a source host is sending a large amount of data to destination, it will take all the bandwidth which leads to slow network performance and access in other connected computers .The network speed and performances reduces as more devices are added.The device referred to is a Network Hub, which is used to connect multiple devices in a network. Its disadvantage is that it broadcasts all incoming data to all connected devices, potentially causing unnecessary network traffic and impacting performance.
Explanation:The device being described in the question is likely a Network Hub. Hubs are networking devices that connect multiple devices in a LAN (Local Area Network). The main disadvantage of a Hub is that it broadcasts the data it receives to all connected devices. This can negatively affect network performance because data might unnecessarily reach devices not intended to get the data, which can create network traffic. For example, if Computer A sends data to Computer B, the hub would broadcast this data to all connected devices, not just Computer B.
This disadvantage is not present in more sophisticated devices like Switches or Routers, as these devices intelligently direct the traffic to the intended recipient only, instead of broadcasting it to all devices.

For a DBMS to be efficient and more functional, data redundancy needs to be eliminated. This can be accomplished by creating smaller tables, with stable data structures, using what process?
a.) Data administration
b.) Data dictionary
c.) Data normalization
d.) Data retrieval
Answer:
c.) Data normalization
Explanation:
Data normalization is the a process to organize tables in the database in such a way that data redundancy and anomalies (as a result of data manipulation) can be eliminated. So data normalization arranges the data in the form of tables, remove redundant data from the tables and eliminates duplicated data and also makes a large table into smaller tables. These small tables can then be associated to each other by making relationships between them. Data normalization also reduces the problems created by the data modification. These are often referred to as data anomalies e.g. insertion , deletion and update anomalies. Lets say a large table has redundant or repeated data. Without normalization the redundant data will take more space in the memory. Also it will not be easy to update data in such a table as it might result in data loss.3 basic types of database normalization forms are First normal form (1NF), Second normal form (2NF) and Third normal form (3NF). Others include Boyce-Codd Normal Form (BCNF) , Fourth Normal form etc.1NF states that columns of the tables which are also called attributes should have atomic values, 2NF form handles Partial Dependency and 3NF form handles Transitive Dependency.In JavaScript, what is the term for a built-in method that does not belong to any particular object, such as the isNaN() method?
Answer:
Top-level function is the correct answer.
Explanation:
Top-level function is the method in the JavaScript that is not a part of any other objects. It is built-in method in JavaScript such as isNaN() function, eval() function, _dump() function, print() function and may other functions. These functions are the object of the global variable or object.

If you were investigating login issues on a Windows computer, which portion of the Event Viewer logs would be a good place to start your investigation?
Answer:
If we are investigating login issues then we have to start with 'security logs' in 'windows logs' portion of Event viewer.
Explanation:
Much information about login issues is contained in log files which are related to security because it is mostly security issue. Some it is also better to start with 'system logs' portion of windows logs portion of Event viewer when there may be system problems instead of security issues. But in most cases there is security issues so 'security logs' is better option overall
Final answer:
To investigate login issues on a Windows computer, start by checking the Security logs in the Event Viewer, as they record security-related events including login attempt details.
Explanation:
If you were investigating login issues on a Windows computer, a good place to start your investigation would be the Security logs in the Event Viewer. The Security logs, which are part of the Windows Logs category, record security-related events such as valid and invalid login attempts as well as events related to resource use like file operations and user management. By examining the details contained within these logs, you can identify patterns or anomalies that may indicate what is causing the login issues.

When an object is created, the attributes associated with the object are called: A. instance fields B. instance methods C. fixed attributes D. class instances
Answer:
Option A is the correct answer for the above question
Explanation:
The object is used to take memory for the class member and functions because the class is the only structure which defines the types of the member for that class. The class object is used to reference a member of the class. The object of the class is known as an instance of the class and the one object variables value is different from the other objects variable value for the same class. So the object is used to holds the instance field because the object is used to initialize the value of the variable of the class. So the attributes associated with the class object can be called the instance field . The above question also asked the same and the answer is Instance field which is stated from the option A. Hence Option A is the correct answer while the other is not because--
Option B states about instance method which refers to the method of a class for which that object is created.Option C states about the fixed attributes which are not the correct answer.Option D states about class instances which refer to the object of the class.In the context of programming, the attributes associated with an object are called instance fields. These variables differentiate different instances of a class.
Explanation:When an object is created in the realm of programming, the attributes associated with the object are called instance fields. These are variables that are associated with an instance of a class. Another way to comprehend it is to visualize a class to be a blueprint. Each instance (or object) of that class can have different values for these fields. For example, if we have a class 'Car', potential instance fields might include color, make, model, etc. Each specific car (instance) would have specific values for these attributes.
