The BSD protocol is a member of the "Permissive free Software license," which gives minimal restrictions on software reuse. The BSD protocol allows authors to use the resources under the agreement to incorporate them into a private version of the software, which can be published using the closed source software protocol.

(3), Apache:

Apache licence is the protocol used by the famous non-profit open source organization Apache. The agreement is similar to BSD, encouraging code sharing and respecting the authorship of the original author, as well as allowing the code to be modified and republished (as open source or commercial software). The conditions that need to be met are similar to BSD:

The user who needs to give the code a copy of Apache licence if you modify the code, it needs to be described in the modified file. In the extended code (modified and in code derived from the source code) need to have the original code of the Agreement, trademarks, patent statements and other original author rules need to include the instructions. If the rereleased product contains a notice file, the Apache Licence is required in the notice file. You can add your own permission to the notice, but you may not be able to make changes to Apache licence. Apache licence is also a friendly license for commercial applications. Users can also modify the code as needed to meet their needs and publish/sell as open source or commercial products.
