Alias names are short, easy-to-remember names used on the Internet instead of long, hard-to-remember names.
Alias names can be complicated personal names, addresses, sequences of letters or numbers. The alias names are assigned to the User- ID and simplify the input. For example, the user ID 4711224 can be assigned the alias name Klaus. Internet Service Providers( ISP) offer software to support alias names.
Alias names are not only used on the Internet, but are also supported by some computer operating systems.
