Answer:
The difference between the centralized and the distributed database architecture are as follows:
- The centralized database is the type of database which works on the single file in the database. Whereas, the distributed database works with the multiple files in the database.
- The centralized database refers to the proper planning and the helps in the decision making in the management system. Whereas, in the distributed database system the data are mainly distributed in the multiple files and the user can easily access the near by file in the database system.
- In the centralized database, if the database are get fail then the overall system come to halt. On the other hand in the distributed system, if the component get failed then the performance of the system are get reduced.

Answer:
A. Loopback tool
Explanation:
Loopback tool or adapter is a small device used to test networks ports and help identify simple network connection issues, this is a great tool when mapping out a physical layout of a network and quickly identify active ports on a switch.
This tool works by taking the transmitted signal and redirecting it or looping it back into the receiving end of the same connection.
Answer:
a. channel width
Explanation:
In wifi, channel width defines how broad the spectrum is available to transfer data. A good example is, when using 5GHz it is usually recommended to use 40MHz as channel width, If you use 2Ghz, you are recommended to use 20Mhz as channel width, because 20MHz is supported by older devices.
Basically, channel width defines the broadness of a wifi signal.
Answer:
// CPP program to find type of input character
#include <iostream>
using namespace std;
void charCheck(char input_char)
{
// CHECKING FOR ALPHABET
if ((input_char >= 65 && input_char <= 90)
|| (input_char >= 97 && input_char <= 122))
cout << " Alphabet ";
// CHECKING FOR DIGITS
else if (input_char >= 48 && input_char <= 57)
cout << " Digit ";
// OTHERWISE SPECIAL CHARACTER
else
cout << " Special Character ";
}
// Driver Code
int main()
{
char input_char = '$';
charCheck(input_char);
return 0;
