Data, Information and Files

What is data?

Data is raw alphanumerical characters and symbols which when arranged or presented in a certain way or manner becomes useful and is called information.

What is information?

Therefore, information is readable data for humans. Without some kind or type of way or method of manipulating the data into a readable or usable way, then it is simply raw data -i.e., a string of letters, numbers and symbols.

What is a file?

A file is a digital version of an analogue document (paper document). So, for example, before computers were invented, people used typewriters to type (document) a message, letter or; formal or informal paper of some kind. The digital revolution changed the face of typography and the recording of and storing of written text. A new era was born and it had transformed into an electronic form of a preceded physical handheld paper form.

File Formats

File formats are really just different kinds of files, whether it's a picture, a video or a document - they're all examples of file formats. They are not the same - i.e., they are different.

So, for example, .mp3 audio files are a different kind of file format than a .mp4 video file.

Similarly, a .docx file is not the same as a .ppt file.

File Extensions

A file extension is any set of letters or numbers that go after a dot '.' which goes after the actual filename. For example: FileABC.docx is a .docx file and has a file extension .docx. The filename is FileABC.

So file extensions are the 3 or 4 letters and numbers that go after the dot (.) after the name of the file.
