booleans
 

is it neccessary to set booleans for servers??
if yes
then which booleans are set on for which servers??
plz help me out

Hold on a minute. You tried to run a server without setting your booleans? Risky business, that.

Seriously, now. What do you mean by 'set booleans'? What servers? Your question is completely ambiguous; you need to provide more context, examples, information in general.

A 'boolean', in the most general sense, is simply a variable which has one of only two possible values: True or False. What boolean variables are you talking about?

The switch button is a boolean. You have to switch the server on to use it. This is the first boolean you need when seting up a server.

Actually, you have to switch on the power at the wall first ... ;)

Some the wall plug is already on (no switch) so you just need to plug it in.
