Concurrency is another word for multitasking, and we multitask all the time in our daily lives. We put the coffee on, start up the computer, and while it’s booting grab the paper to glance at the news. Computers are also capable of doing multiple tasks—you may have multiple tabs open in your web browser while your mail application is fetching new email, for example.
Juggling multiple tasks is also very common in enterprise systems, such as when you’re processing incoming orders, handling invoices, and doing inventory management, and these demands only grow over time. With concurrency, you can achieve higher performance; by executing in parallel, you can get more work done in less time.
