A Process is an instance of an running application. And a THREAD is the Execution stream of the Process. A process can have multiple Thread.

When a process starts a SPECIFIC memory AREA is allocated to it. When there is multiple thread in a process, each thread gets a memory for storing the variables in it and plus they can access to the GLOBAL variables which is common for all the thread.

Eg. A Microsoft Word is a Application. When you OPEN a word file, an instance of the Word starts and a process is allocated to this instance which has one thread.
