What data type is a letter?
The integer data type ( int ) is used to represent whole numbers that can be stored within 32-bits.
The decimal data type ( dec ) is used to represent 64-bit floating point values.
The text data type ( text ) is used to represent values that contain uppercase and lowercase letters, numbers, spaces, and symbols..
What is Data example?
Data is defined as facts or figures, or information that’s stored in or used by a computer. An example of data is information collected for a research paper. An example of data is an email.
What is data type and explain their types?
A data type is a type of data. Some common data types include integers, floating point numbers, characters, strings, and arrays. … They may also be more specific types, such as dates, timestamps, boolean values, and varchar (variable character) formats.
Is real a data type?
A real data type is a data type used in a computer program to represent an approximation of a real number. Because the real numbers are not countable, computers cannot represent them exactly using a finite amount of information. Most often, a computer will use a rational approximation to a real number.
What is data type explain?
In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. … This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.
How many types of data types are there?
Data types are divided into two groups: Primitive data types – includes byte , short , int , long , float , double , boolean and char. Non-primitive data types – such as String, Arrays and Classes (you will learn more about these in a later chapter)
What are the basic data types?

What type of data is age?
Age is frequently collected as ratio data, but can also be collected as ordinal data. This happens on surveys when they ask, “What age group do you fall in?” There, you wouldn’t have data on your respondent’s individual ages – you’d only know how many were between 18-24, 25-34, etc.
What are the 2 types of data?
Understanding Qualitative, Quantitative, Attribute, Discrete, and Continuous Data TypesAt the highest level, two kinds of data exist: quantitative and qualitative.There are two types of quantitative data, which is also referred to as numeric data: continuous and discrete.More items…•
What are the 4 data types?
Some are used to store numbers, some are used to store text and some are used for much more complicated types of data ….Data typesString (or str or text). … Character (or char). … Integer (or int). … Float (or Real). … Boolean (or bool).
What are the 3 types of data?
Jeff Bertolucci of Information Week has written a new article about what distinguishes the three types of Big Data analytics: descriptive, predictive, and prescriptive.
