What is the difference between a workstation and a microcomputer?

In 80s and 90s microcomputers(PCs) were having lesser storage, lower quality display, lesser processing speed, lesser efficiency and less capable softwares. Workstations were having greater storage, high quality display and higher processing speed, high efficiency and highly capable softwares.

But now both became same as we use high memory, latest processors and extreme softwares in PCs also.
