The “type” provides the information about the chunk of memory which holds the data and thus categorizes it such that the valid operations that can be performed on that data are defined. In object-oriented programming, the types include classes (user-defined), strings and integers (primitive types), lists/arrays/vectors/hash (containers) [2]. A variable in a program can accept a certain range of values during its execution. The upper bound value for that range marks the type for that particular variable. For example, if there is a variable num of type int in the program then num can accept only integer values during every execution of the program. Such languages where all the variables are associated with the data type are called typed languages. Certain languages do not specify separate data types for each of the variables but contains a single universal type that holds all the values.

Advantages of statically typed vs. dynamically typed languages
Typed and Untyped languages
The “type” provides the information about the chunk of memory which holds the data and thus categorizes it such that the valid operations that can be performed on that data are defined. In object-oriented programming, the types include classes (user-defined), strings and integers (primitive types), lists/arrays/vectors/hash (containers) [2]. A variable in a program can accept a certain range of values during its execution. The upper bound value for that range marks the type for that particular variable. For example, if there is a variable num of type int in the program then num can accept only integer values during every execution of the program. Such languages where all the variables are associated with the data type are called typed languages. Certain languages do not specify separate data types for each of the variables but contains a single universal type that holds all the values. They do not define the range for the variables and are called untyped languages (assembly languages) [4].
