What is a process and a thread, and how are they used in your profession?

"A process and a thread are very similar in concept. In the execution of a program, both define the sequences and code a program executes. The difference between a process and a thread is that a thread is a segment of a process. Processes can have several different threads which define how the program executes. Another difference is that processes will take longer to terminate than individual threads. Finally, threads can share memory while processes can't."
