Data types

Unlike humans, a computer does not know the difference between "1234" and "abcd." A data type is a classification that dictates what a variable or object can hold in computer programming. Data types are an important factor in virtually all computer programming languages, including C#, C++, JavaScript, and Visual Basic. When programmers create computer applications, both desktop and web-based, data types must be referenced and used correctly to ensure the proper result and an error-free program.

Common examples of data types

Depending on the programming language, there may also be many more data types that serve a specific function and store data in a particular way. Understanding the different data types allows programmers to design computer applications more efficiently and accurately.
