Poke means hello. Who person poked you means he say hello

I think the general purpose of this, at least in the beginning, was to kind of say hi to friends that you haven't added yet, let them know your on facebook and that you should become friends on facebook as well. Nowadays, its used for anything. It's just a little thing fun that Facebook decided to have on their website. It doesn't affect anything else on the site.

To get attention of friends on Facebook called poke.

Poking is done to grasp the attention.

Just like making fun, or to take other attention towards you.
