Let's say, your mother have invented a new awesome pie recipe and wants to share.
If she shares with her friend under GPL licence, he promises to tell the recipe of this pie to anyone who asks him, but acknowledging that your mother is the author and making that other guy to promise the same thing. And if anyone tries to make a giant multi-layered pie that uses your mother's recipe, he has to promise the same thing for an overall design of his pie.
LGPL is basically the same as GPL, but without the last clause, so giant pies can be made while disclosing only your mother's recipe, not overall recipe.
If your mother shares under New BSD licence, basically the only thing she asks for is to say that that pie is her invention. Also, no one has the right to advertise his pie derived from your mother's pie with stressing that it is derived from your mother's pie.
MIT licence is similar to BSD.
Apache is even less restrictive. Everyone can do anything with the pie recipe, except using your mother's name on their deri
