Mariulka [41]

An array is an indexed collection of data elements. First you must declare an array, give its name and data. Once your arrays are declared, you access the elements in an array with the array name, and the index number inside brackets [ ].
So, in every programming language, when you access data stored in an array, you must use a command [] (brackets) containing a value that accesses memory occupied by the array.

The type of wireless access that uses a modem to connect to cell towers is called ___

Alex_Xolod [135]

Answer:

What are the Wireless Broadband Technologies?

Wireless broadband services are similar to wired broadband in that they connect to an internet backbone usually a fiber-optic trunk; however they don’t use cables to connect to the last mile or business/residences. Instead they use Wireless Fidelity (Wi-Fi) connections or radio waves. A computer or mobile device has a wireless adapter that translates data into a radio signal and transmits the signal using an antenna. A wireless router receives the signal, decodes it and then sends it to the Internet through a wired Ethernet connection.

Fixed wireless is a type of high-speed Internet access where connections to service providers use radio signals rather than cables. Fixed wireless offers connections speeds between 1 and 10 mbps and use transmission towers similar to cell phone towers that communicate to a resident’s transceiver equipment that, as the name implies is fixed at the premise. The transceiver equipment communicates with the providers’ ground stations.

Wireless fidelity (Wi-Fi) is a fixed, short-range technology that is often used in combination with DSL, fixed wireless, fiber, or cable modem service to connect devices within a home or business to the Internet using a radio link between the location and the service provider’s facility. Wi-Fi service can be available in your home or at community locations (airports, coffee shops, schools, businesses, etc.) and are often called “hotspots.” A Wi-Fi network uses radio waves, similar to two-way radio communications. A computer has a wireless adapter that translates data into a radio signal and transmits it using an antenna. A router receives the signal, decodes it, and then sends the information to the Internet using a physical connection, usually via an Ethernet cable, a cable that carries the broadband signal between the modem, router, computer, and other wired Internet capable devices.

Mobile Wireless (3G, 4G)

Mobile wireless is high-speed wireless broadband connection that is accessible from random locations. The locations depend on the provider’s cellular towers and monthly service plans. Many technologies make up wireless networks, but no matter the technology or acronyms you read or hear, mobile wireless networks are radio systems.

Mobile wireless services are continually being upgraded to provide data transmission speeds considered to be broadband. The faster mobile wireless networks are referred to as 3G or 4G.The “G” stands for “generation,” meaning 3rd and 4th generation or the evolution of broadband cellular networks; supposedly, each generation provides a faster more secure wireless network. A mobile wireless service requires a base station that is connected to a high capacity landline data transmission network to reach the Internet. In other words, it’s never wired OR wireless; ultimately, it has to be both. Wireless broadband in common usage means that the so-called “last mile” connection to the user is done via radio signals from a tower to a cell phone or other wireless devices (e.g., a tablet).

Long Term Evolution (LTE)

LTE is a 4G technology provides increased peak data rates, reduced latency, scalable bandwidth capacity than 4G predecessors. LTE can manage multi-cast and broadcast streams and handle quick-moving mobile phones. It uses an IP-based network architecture that allows for seamless handovers for voice and data to older model cell towers.

Satellite

Satellite broadband is sometimes the only option available to users in very rural or sparsely populated areas. Like telephone and television services, satellites orbiting the earth provide necessary links for broadband. With satellite service, you must have a clear view of the southern sky. Satellite service can be disrupted by weather conditions and changes in line of sight to the orbiting satellite. Satellite may have a higher monthly service charge than other broadband options and the need to purchase more home or business equipment compared to the other options. Because satellites are located a significant distance from customers, there are issues of “latency” and therefore a noticeable time lag between sending and receiving data by the end customer.

Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased the consumer’s line of sight to the orbiting satellite, and the weather. Satellite speeds may be slower than DSL and cable modem, but they can be about 10 times faster than the download speed with dial-up Internet access. Service can be disrupted in extreme weather conditions.

Write a full class definition for a class named Player , and containing the following members:

Paraphin [41]

Answer:

I used C++ to implement this program using dev c++, however, i defined the public method inside the class. The code with illustration of this question is given in section phase. If you want to define the classes outside from class then you can use scope resolution operator to access the method of the class. However, the complete running code is given below in explanation section

Explanation:

#include <iostream>// included preprocessor directive

using namespace std;

class player// class player is started from here

{

private:// class varaibles are set at here and scope of varialbe is private.

string name;//variable for getting and setting name of player

int score;//variable for getting and setting score of player

public:// declaring public method that can be accessbile outside of class but in this program

void setName (string name)// public method for setting name of player

{

this->name=name;// name is initialized by paramenter name to variable name

}

void setScore(int score)//publice method for setting score of player

{

this->score=score;

}

int getScore()// public method for getting score of player

{

return score;// on call, return the score of player

}

string getName()// public method for getting name of player

{

return name;// return player name;

}

};//end of class "player"

int main()//main function get executed

{

player firstPlayer;//class object "firstPlayer" is created

firstPlayer.setName("Renaldo");// firstPlayer name is initialized

firstPlayer.setScore(500);// assgined score to firstPlayer

string getname=firstPlayer.getName();// get name of firstPlayer

int getscore=firstPlayer.getScore();//get score of firstPlayer

cout<<getname;//print name of firstPlayer

cout<<"\n";//line break

cout<<getscore;//print score of firstPlayer

cout<<"\n";//line break

return 0;//end of program

}
