What Does Distributed Processing Mean?

Distributed processing is a setup in which multiple individual central processing units (CPU) work on the same programs, functions or systems to provide more capability for a computer or other device.

Techopedia Explains Distributed Processing

Originally, conventional microprocessors involved just one CPU on a chip. As microprocessor engineering evolved, manufacturers discovered that to speed up processes, more than one processor could be combined on a single unit. Many modern processors involve a multi-core design, such as a quad-core design pioneered by companies like Intel, where four separate processors offer extremely high speeds for program execution and logic.
