From MSDN:

A strong name consists of the assembly's identity — its simple text name, version number, and culture information (if provided) — plus a public key and a digital signature.

You can use strong naming to ensure that when you load a DLL you get exactly the DLL you were expecting and not some other DLL that happens to have the same name.

A 'strongly named' assembly is one that has been signed with a key to ensure its uniqueness (for example, in the GAC). See here for more details:
