That depends on the context or the language you are using. In some computer languages those signs can mean entirely different things.
In the bash scripting language '>>' means 'append to the named file' as in:
echo "what?" >> my_file
In C, '>>' means 'shift the value right by one bit' while '<<' means 'shift the value left'. However, in C++, '<<' can also mean 'write to standard output'.
