                                    If you could organise your computer files like a fantasy kingdom, with each
                                    folder representing a different realm or kingdom. How would you design the
                                    folders to reflect the magical world of your imagination?


                      DIFFERENT FILE FORMATS

                  You must have observed that whatever we do on a computer is saved as a file. But every file stores

                  a different type of data, like a Word file stores text, a video file contains multimedia, an audio file
                  contains audio and a picture file stores pictures. So, how does a computer differentiate between
                  different types of files? The file type is also called the file format. So, all these files contain different
                  types of data and are saved in a specific format. The file format can be determined by the file
                  extension. A file extension is a group of three or more characters used to identify the type of a file. It
                  helps an operating system recognise the different types of files. The file formats of different types of
                  files depend upon the software used for creating those files. Software puts a file extension after the
                  file name to specify its format. Some of the most commonly used file extension, or file formats are:
                      JPEG:  It  stands  for  Joint  Photographic  Experts  Group.  It  is  used  to  store  images.  The  file
                     extension of a image file can be .jpeg, .jpg, or .jpe.
                      MP4: An MP4 file is used to store multimedia content. It can contain audio, video, movies, and
                     still images. A file with an MP4 extension is an MPEG-4 video file.
                      MP3: It is an audio file format that is used to store music files. MP3 stands for Moving Pictures
                     Expert Group. The file extension of an audio file is .mp3.

                      DOCX: It is used to save Word documents. This document stores images, text, pictures, and
                     tables. The file extension of the Word file is .docx.
