They are all predefined local accounts, none of them have a password and
none are used to access the network.
localsystem is the most privileged account in a system, it's the only
account that is able to access the security database (HKLM\Security). It's
token contains the SID's of NT_AUTHORITY\SYSTEM and Builtin\Administrators.
Local System acts as the machine account on the network.

Local Service has very limitted privileges (SeAditNamePrivilege,
SeChangeNotifyPrivilege and SeUndockPrivilege + those assigned to "users"
and "Authenticated" users ) on the system, he presents the "anonymous"
user's credentials on the network.

Network Service has very limitted privileges the (SeAditNamePrivilege,
SeChangeNotifyPrivilege and SeUndockPrivilege + those assigned to "EveryOne
" and and "Authenticated" users ) on the system, he presents the machine
credentials on the network, the remote token contains the "EveryOne" and
"Authenticated User" group SIDs.
