Answer:
We learned that an ideal multiple access protocol has FOUR desirable
characteristics, describe them.
Explanation:
1.- Very experienced technology and easy to implement.
2.- Rigid resource management and unfit for variable traffic flows.
3.- Requires antenna duplexer for duplex transmission.
<u>Duplex</u> <em>is a term used in telecommunication to define a system that is capable of maintaining two-way communication, sending and receiving messages simultaneously.
</em>
4.- Normally FDMA is combined with multiplexing FDD.
<u>FDMA</u> (acronym in English for Frequency Division Multiple Access) <em>is a multiplexing technique used in multiple communication protocols, both digital and analog, mainly radio frequency, and among them in mobile phones of GSM networks.
</em>
<u>FDD</u> (Frequency Division Duplexing in English) <em>designates a duplex method in the environment of wireless telecommunications and over certain wired networks.</em>
The biggest security issue with using social networking sites to market your listings is Criminals may use social networking sites to identify your personal data.
<h3>What is a social marketing site?</h3>

The program is an illustration of built-in functions
<h3>What are
built-in functions?</h3>
They are named program statements that have a predefined purpose
<h3>The actual program</h3>
The program written in C++, where comments are used where required is as follows:
#include <iostream>
#include <cmath>
#include <ios>
#include <iomanip>
using namespace std;
int main (){
double x;
double y;
double z;
cin>>x;
cin>>y;
//This calculates the given expression
z = pow(sqrt(y),x);
cout << fixed<<setprecision(2);
cout<<z<<endl;
return 0;
}

Answer:
Collaborative filtering
Explanation:
This is one out of five on the Recommender system apart from most popular items, Association and Market Basket based Analysis, Content-based analysis, self and hybrid analysis where we use both content-based and collaborative based approach together. And the Recommender system is a very important topic in Data science. For this question, remember that Collaborative filtering focuses on user and various other user's choices which are mathematically alike to concerned users, and which we find with the study of a large data set. Thus, we can predict from our above study that what are going to be likes of concerned users, and at the item level, whether that item will be liked by the concerned user or not. And this is prediction, and we use this approach in Machine learning these days. For this question, and as mentioned in question the requirements, answer is Collaborative filtering.
