Answer:
The description for the given question is described in the explanation section below.
Explanation:
The various forms of networks and their contrast are as follows:
<u>LAN</u>
This is another form of connection that links the machine and system community together in such a limited but wider range than those of the PAN network. LAN will attach the two as well as three surrounding buildings for shared folders including assets as well as knowledge exchange.
<u>MAN</u>
MANs represent networks or channels that are broader than LANs although smaller than WANs since they cover the whole metropolitan area which might be a city rather than a county.
<u>WAN</u>
WANs seems to be the channel's biggest and wider than MANs, allowing machines to connect and communicate to one another and miles away, and it can also link all machines across the globe to either the Internet as well as network access.
<u>WLAN</u>
Wireless LAN is used to link connections in such a LAN network using Wi-Fi wireless innovations. The positive point here is really that we don't have to manually interact via cables in WLAN, and instead promote flexibility including networking for portable devices.
Answer:
The solution code is written in Java.
- import java.util.Scanner;
- public class Main {
-
- public static void main(String[] args) {
-
- String letters[] = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J"};
- Scanner scnr = new Scanner(System.in);
- int numRows;
- int numColumns;
- int currentRow;
- int currentColumn;
- numRows = scnr.nextInt();
- numColumns = scnr.nextInt();
-
- for(currentRow = 0; currentRow < numRows;currentRow++){
- for(currentColumn =0; currentColumn < numColumns; currentColumn++)
- {
- System.out.print((currentRow + 1) + letters[currentColumn] + " ");
- }
- }
- }
- }
Explanation:
Firstly, we need to create an array to hold a list of letters (Line 6). In this solution, only letters A - J are given for simplicity.
Next, we declare all the variables that we need, numRows, numColumns, currentRow and currentColumn (Line 8 - 11).
Next, we use Scanner object, scnr to prompt user to input integer for <em>numRows </em>and <em>numColumns </em>(Line 12-13).
At last, we use two-layer for loops to traverse through the number of rows and columns and print out the currentRow and currentColumn (Line 15-19). Please note the currentRow is added by 1 as the currentRow started with 0. To print the letter, we use currentColumn as an index to take out the letter from the array.
A <em>parameter </em>is a variable used to pass information to a method.
Answer:
A: Radio waves.
Explanation:
Computers use short-wave radio in order to communicate with devices in it's immediate vicinity.
