It would just be pure text characters, so things like letters, digits, punctuation symbols and other symbols that you can get from your keyboard. It would not be things like a photograph, which is a graphical file.
An ASCII file is just a text file.
There are no set file extensions for an ASCII text file, however one that is commonly used is .txt
When files are transferred in ASCII mode, the transferred data is considered to contain only ASCII formatted text. The party that is receiving the transferred data is responsible for translating the format of the received text to one that is compatible with their operating system.

*.txt. In reality the ascii file can have any extention. A ASCII file is just a raw text file with no enbedded codes within the file.
You can distinguish between binary and text files, and for the most part even identify what type of binary file, by using the "file" command. For example:~$ file unknownfileunknownfile: PNG image data, 155 x 155, 8-bit/color RGBA, non-interlacedThis tells you that the file is a PNG file by reading metadata and/or magic numbers in the file. When used on a text file, the command will return "ASCII text" or "Unicode text."
Emails can be plain text. That is ASCII. Or it can be written in HTML coding.
To create as ASCII file use TextEdit (in the Applications folder). If you have the option to Make Plain Text in the Format menu select that. When saving the file use Save As... and from the Encoding drop down menu select ASCII - if it is not an option select Customize Encodings List and tick the ASCII box to add it to the menu.
.txt is a common choice.
The PPM image format will dump image data into an ASCII format which will essentially create a 'flat' text file with a series of numerical values. Look for 'GNU Image Manipulation Program' for a free solution.
