Base 8 numbers (octal) also take less space than binary (base 2) numbers. In fact, you can represent 3 bits of information with only one space using octal! For this reason, it's used for Unix file permissions. Have you ever wondered why a file has a permission like 776? Well those are octal numbers representing the permission bits (read, write, execute) for each type of user (owner, group, everyone else).
