Difference b/w Thread and Process

Can someone Describe the difference between a Thread and a Process?

Google is our friend.

A process is a collection of virtual memory space, code, data, and system resources.
A thread is code that is to be serially executed within a process. A processor executes threads, not processes, so each 32-bit application has at least one process, and a process always has at least one thread of execution, known as the primary thread.
A process can have multiple threads in addition to the primary thread. Prior to the introduction of multiple threads of execution, applications were all designed to run on a single thread of execution.
