ABBREVIATIONS

Abbreviations are shortened forms of a written word, phrase or name used in place of the whole, for example:  ‘Dr.’ for Doctor, ‘Mr.’ for Mister, ‘gym’ for gymnastics, ‘Tim’ for Timothy, p.s. for post script. Abbreviations are found in almost every area of life.
Acronyms and initialisms are also abbreviations.

ACRONYMS

An acronym is created from the initial letters of a long name or phrase, and pronounced as a word, for example, NATO (North Atlantic Treaty Organization).
Since are acronyms are treated as words and pronounced as words, there are no full stops between the letters.
