how can I understand the difference between algebra, sigma algebra and topology(adsbygoogle = window.adsbygoogle || []).push({});

If I take the set A that contains a,b,c,d,e,f

the set C that contains A,phi,{a},{b,c,d,e,f}

then C is algebra on A

and C is sigma algebra on A

and (A,C) is topological space

is that true?

what is the difference ?

give me example like the obove to see the difference between them?
