Regular speed multitable tournaments typically last 4-12 hours, so its a bit like running a marathon. If you are new to running, you dont want to start with a marathon. And likewise with poker you want to start with games, that require less time commitment. Like cash games or small tournaments, which are usually going to be called SnG (Sit and Go). The classic 9-man SnG is a great game for beginners. You buy in for a dollar or even less, then you sit down and wim-bam-bo, left-and-right, dust away your stack or get lucky, and then its over. Or start with 2NL cash games, if you are more serious about it. Cash games are better for learning to play with deeper stacks including the crucial late streets, turn and river.
