cash VS tournament : the difference.

[eberetta1]

in a cash game, you can always reload if you want to stay on the table.
So if I have a $100 bankroll, I will go into a 1c/2c room with $2 and if I lose
an all-in I have only lost $2 and I can stay at the table if I get another $2 from
my remaining $98 bankroll. blinds stay 1c/2c the whole time in a cash game.

In a $2 buyin tournament, if you lose an all-in, you are out of the tournament, unless it is a rebuy.
Blinds continually go up every level. Levels usually last 6 to 15 minutes.
