This article aims to introduce you to distributed systems in a basic manner, showing you a glimpse of the different categories of such systems while not diving deep into the details. Security • More susceptible to external attack. The terms "concurrent computing", "parallel computing", and "distributed computing" have much overlap, and no clear distinction exists between them.The same system may be characterized both as "parallel" and "distributed"; the processors in a typical distributed system run concurrently in parallel.
