What is a Process
A process or running process refers to a set of instructions currently being processed by the computer processor.
Windows Processes are Windows Services and background programs you normally don’t see running on the computer. A process may be a printer program that runs in the background and monitors the ink levels and other printer settings while the computer is running.
A typical computer has dozens to hundreds of processes running all of the time to help manage the operating system, its hardware and the software running on the computer. Refer to below image of my running processes (I have over 150) with one open application (WordPress) under Google Chrome. The sort order is by the Memory column.

Also, note that Google Chrome has 32 instances of the program running. Just click the arrow next to the Name field to expand the list. See following image:
