Answer:

d. Knowledge refinement subsystem

Explanation:

One of the biggest problems in companies today, whether large or small, is the use of knowledge that is constantly generated through all its processes and all its staff. This difficulty of using the knowledge of the company arises because the sources of it are very varied and range from documents to databases, discussion groups and people themselves.

The component that is in contact with the direct source of knowledge is the knowledge acquisition subsystem and for this same reason represents one of the largest bottlenecks in organizations. Many times it is not just an expert but a group of them who are responsible for developing the system and "emptying" their knowledge in the base. There are many tools and methods to obtain this knowledge among which is the interview, the observation and the creation of scenarios.

With the knowledge acquisition subsystem and the knowledge base ready, other processes must be followed to achieve the elaboration of the rules, the interface with the user and the inference mechanisms, however, the purpose of this article is to highlight the importance of the knowledge acquisition process, since it is the initial step in the development of an expert system and lays the foundation for its proper functioning.

Stolb23 [73]

The high-speed fiber network that is already in place and being used for wide area networking (wan) transmissions, before the IEEE developed the 10gbe ethernet standards is called SONET.

<h3>What does SONET stand for in networking?</h3>

SONET  is known to be a term that is called Synchronous Optical Network.

This is said to be defined as a standard  that is known to be used in linking or in the act of connecting fiber-optic transmission systems and it is one that is sold in North America only.

Therefore, The high-speed fiber network that is already in place and being used for wide area networking (wan) transmissions, before the IEEE developed the 10gbe ethernet standards is called SONET.

Identify a logical operation (along
tankabanditka [31]

Answer: Provided in the explanation section

Explanation:

The Question says;

Identify a logical operation (along

with a corresponding mask) that, when

applied to an input string of 8 bits,

produces an output string of all 0s if and

only if the input string is 10000001.​

The Answer (Explanation):

XOR, exclusive OR only gives 1 when both the bits are different.

So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND

with 00000000 would also give 0,

but it would give 0 with all the inputs, not just 10000001.

Cheers i hope this helped !!

How do the interests of carriers differ from the interests of websites? What are the implications for websites from a value chai
Keith_Richards [23]

Answer:

Explained below.

Explanation:

- The interest of the carriers has it's major focus on the process of getting funds from both individual customers and corporate entities that run the websites. However, the interest of websites’ has it's major focus on the process of generating funds in form of subscriptions or funds gotten from paid adverts from both individual customers and corporate entities.

- In terms of value chain perspectives; the websites experience far more pressure to keep fresh and exciting features and services on their platform while carriers don't experience that but only experience having to compete with innovations being done by their existing competitors to remain leaders in the field.

Create a float variable named diameter. This variable will hold the diameter of a circle. d. Create a float variable named PI.
Basile [38]

Answer:

float diameter=2*r; //hold the diameter of a circle

float PI; // float variable named PI.

Explanation:

Here we have declared two variable i.e diameter and PI of type float. The variable diameter will hold the diameter of a circle i.e  2*r  where r is the radius of a circle.

Following are the program in c++

#include <iostream> // header file

using namespace std; // namespace

int main() // main function

{

   float r=9.2; // variable declaration

float diameter=2*r; //hold the diameter of a circle

float PI=3.14; // float variable named PI hold 3.14

cout<<"diameter IS :"<<diameter<<endl<<"PI IS :"<<PI; // display value

  return 0;

}

Output:

diameter IS :18.4

PI IS :3.14
