<u>Explanation:</u>
What is modulation?, let us understand. The <em>process of converting analog to digital signal is called modulation and demodulation is vice-versa.</em> The computer connects internet classically using telephone wire.
The <em>telephone wire understands only analog signal and a computer understands only digital signal.</em> So Modem’s role is to take care of this aspect while <em>connecting to the internet.</em>

Explanation:
Arrays are allowed to store multiple elements of the same data type, all of them stored with the same array hence preventing the need for creating separate variables for each element. An array therefore will act as a container for storing several variables all of the same type. This offers a lot of convinience and enhances better memory space management. In java arrays are declared by:
dataType[] arrayName;
Where dataType is the datatype of elements to be stored in the arrays. This is followed by a pair of square brackets then the name of the array.
for declaration and initialization in Java, the new keyword is used as:
dataType[] arrayName = new dataType[arraySize];
