A data type is an attribute of data that tells the compiler how the programmer intends on using the data. A data type limits the values that an expression might take.

Explanation
There are many different types of data types that are used for different tasks. Similar to a Mechanic using the right tool for the job, it is the job of the programmer to figure out which data type would be appropriate to use.
Information falls under a different data type. Different data types are used for different intents: for math you may use integers, floats, doubles, etc. while for keeping a contact list, strings would be more appropriate.
As mentioned before, data types limit which operations can be used on them. A string cannot be added to an integer because an integer can only be a whole number while a string can be a name, address, etc. However, an integer can be added to a string, this is known as Concatenation. It’s all about using the right data type for the right job.
Here is a list of different data types available in C#

Example
Here's an example of a few different types of variables being initialized along with a few Comments
string fullName = "John Doe"; // strings are typically used to store information such as names, addresses, etc. because they can hold text.
string jobTitle = "Sales Associate"; // notice how a string's value has the quotation marks!
bool isStudent= true; // booleans can only be true or false. Great use in conditional statements!
int age = 20; // an int (short for integer) can only be a whole number. Since we typically say age as a whole number, we're using an int
float payrate= 12.50f; // unlike integers, a float (short for floating-point number) can hold more complex numbers with decimal places. Great for displaying the example's payrate!
