Encoding a Digital File…
The data in a computer file is encoded into a format that is established by whatever software application created the file.

The data then needs to be read by the same or a similar software program that can interpret that format and present the data to the user on his or her…
- Computer monitor
- TV screen
- Viewfinder, etc.

For instance… although a photographic image may look exactly the same when displayed in two different file formats on the same screen.
One file may be 100k in size and another may be 1 MB… The difference in file size is caused by how the data is formatted and saved.
