Starting SQL Server Agent and Database Engine as a Network Service or System

Question

It has been a long time since I had to install SQL Server. I do this for a version control system called Plastic SCM on my system.

I'm going to finish the wizard by asking me a lot of questions, and on the Service Accounts tab in the Server Configuration section, he asks me if I want to use NT AUTHORITY\NETWORK SERVICE or NT AUTHORITY\SYSTEM to start either SQL Server Agent or SQL Server Database Engine

My question is, what is different between these accounts?

thanks

The best solution is to use a separate Active Directory account.
