File+types

= FILE TYPES =

Everything is stored in the computer as 1's and 0's - everything, videos, pictures, sounds, programs, games, spreadsheets, documents, everything. This is called Binary Code.
===The computer needs to know what this code means - is it a picture? a letter? music? So different FORMATS are used. Codes that tell the computer how to treat the binary numbers, and how to present the information to you - are you looking at a database, or a video?===

These are 'file types'. When the file is saved, a 'file extension' is added - you have probably seen these:
===There are lots of different file types, some can be read by more than one program, others can only be read by one particular program. Perhaps you've had problems reading or opening a file because you don't have the right software.===
