Difference between sandbox & farm solution

When we create MOSS 2010 solution there are two options for solution type one is sandbox solution and another one is farm solution.
people are very eager to know wht is the difference between them.
sandbox solution:sandbox solution are solution that run in the context of sitecollection.it's resticted.The solution can only access resources of that particulat sitecollection where it was deployed.
By using sandbox solution we can deploy webparts,event receivers,feature receivers,Custom microsoft designer workflows activities,microsoft infopath business logics.It's cannot connect to resources that are not located on local server and can't access database as well as resources in different sitecollections.It is monitored & limited by quotas set by farm administrator.
who can deploy sandbox solution:If the solution contains assembly than only sitecollection administrator deploy it and if the solution does not contains assembly than a user who has full control on root of sitecollection deploy it.
Farm solutions:The scope of farm level solution is farm level so it has full trusted access to all resources and functionality of sharepoint.
