chain of responsibility and command design pattern

[mittalr]

Hi
Can anyone explain the differences between chain of responsibility and command design pattern.
Could a system be designed better if we use both of these patterns together
for e.g
I am having chain of components laid out on the basis of chain of responsibility pattern where one component keeps passing a set of request to other for their set of operations.
The operations performed by components can be done by implementing command pattern.
does it become a viable solution ?
Can these pattern go hand in hand together.

We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in again with a new name which meets the requirements.
Thanks.
