Complete Question:
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.
Group of answer choices
a. Router
b. Switch
c. Bridge
d. Hub
Answer:
d. Hub.
Explanation:
A hub can be defined as a layer one (physical) device used for connecting various network devices such as switches and routers in a local area network (LAN). It comprises of many ports which are used for connecting segments of a local area network (LAN). Hubs are generally considered to be unintelligent because when frames are received at a port, it is then copied to every other connected port on the network.
<em>Hence, the main disadvantage of using a hub 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.</em>
Answer:
Class is the correct answer for the above question.
Explanation:
In an object-oriented language, The class is a structure type template, which is used to define the structure but the class does not take memory when an object is created then it takes the memory of class type. For example, if a user-defined class of one member whose size is 4 bit if its store in memory. When a user creates an object, then the object size is 4 bit.
That's why the class is an only structure while an object is used to give the memory for class member and the member of the class also get executed by the object of that class. class have no existence if object is not created. so when a user wants to create a object, he needs to create the object by the help of class name because class is user defined data type and object is variable of that class.
Then the answer of the above question is that object is created with the help of class which is described above.
