Module tests are one of the most effective methods of identifying as many errors in the source code as possible early on in the software development process. The special feature: the smallest isolatable components of a program are placed in a neutral test environment. If errors appear, it’s obvious they are occurring in the module being tested, which makes them easy to correct.
Various computer networks are connected with one another via the internet. In order to build up such connections, both the sending as well as the receiving systems have to provide transfer interfaces, or ports. Netstat allows you to find out which ports are opened by your own system and which active connections exist — all of this helps reduce the risk of undesired access attempts.
