cat is a powerful tool that prints the content of a file.
However cat is integrated into the Unix philosophy and is not limited to this. On a more general level, cat reads and prints what it reads.
Exploring the concept
To understand how cat works, open a console. If you just type
cat
cat will read from the standard input (the keyboard) and print to standard output (the console).
If you type
cat file
cat will read from (a file named) file and print to standard output (the console).
