2 English for Information Technology A2-B1 Vocational English Teacher’s Book

 

Business matters  

This section focuses on open source versus 

proprietary software, including operating systems. 

Most well-known software is proprietary; in this, the 

programming instructions (code) are a commercial 

secret. Examples include Office (by Microsoft) and 

Photoshop (by Adobe). The code for open source 

software, on the other hand, is freely available and 

can be adapted by anyone. Examples are the Linux 

and Android operating systems, and the Chrome 

and Firefox browsers.
