I don't know what is a workstation.
Someone clarify regarding the
workstation.
Workstations used to be a class of systems intended to be used by single (or alternating) users for tasks that demanded more computing power than a PC offered. They basically died out in the 1990s as economics of scale in R&D allowed standard PC hardware to offer the same (and eventually more) performance for a much lower price.
Workstations were made by companies such as Sun, SGI and HP. They usually ran a proprietary Unix variant and often had specialized hardware as well. Typical applications were scientific computing, CAD and high-end graphics.
"Workstation architectures" were characterized by the goal to deliver high performance for single-user applications with price as a very secondary consideration.
