4-clause license (original "BSD License")
The original BSD license contained 4 clauses:

Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer. 2.

3-clause license
The 3-clause license is identical to the 4-clause license, except that clause no. 3 (the advertising clause) has been removed. Accordingly, clause 4 became clause 3.
Copyright (c) <year>, <copyright holder> All rights reserved. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 1. Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer. 2.

Single-clause license
The single-clause license is identical to the 3-clause license, except that clauses no. 2, 3 have been removed.
Code, licensed under the single-clause license can basically be freely used for product development. It does not impose any restrictions on the created product. No copyright notice has to be included in the documentation.
This license is used by freely available software, such as SEGGER's RTT Code.
