Question

Let's consider a space, or a tab or a carriage return. what each of them is referred to?

Answer 1

A space, a tab, and a carriage return are all used in formatting.

A space primarily refers to the blank character between two words. This is also known as a white space. Two other types of spacing that are commonly used are paragraph spacing (the space between two paragraphs) and line spacing (the line between two paragraphs).  

A tab helps in aligning numerical data or text with respect to the margins set for a document.

A carriage return denotes the characters at the end of a record. A carriage return is also used to create a line break in order to automatically line the cursor with the left margin to start a new paragraph. In computers, the Enter key is used to provide the carriage return functionality.
