But these get bundled up into more human readable things, like characters and array s. This is called abstraction. While abstractions are nice, sometimes we want to work directly with bits. You can do this with bit manipulation, which involves bitwise operations. http://www.theteacher.info/index.php/fundamentals-of-cs/2-logical-operations/topics/2646-bitwise-manipulation-and-masks-and-or-xor eeoc ofo contact
