Workstations is a Special Computer Designed for Technical or Scientific Applications. The offer higher Performance than Mainstream Personal Computers. Especially with respect to CPU and Graphics. Memory capacity, and multitasking capability. These are optimized for the visualization and manipulation of different types of complex data. Such as 3D Mechanical Design & Engineering Simulation (e.g., computational fluid dynamics) & Animation and Rendering of Images, and Mathematical Plots. Typically, the form factor is that of a desktop computer. A consist of a high resolution display, a keyboard and a mouse at a minimum. it also offer multiple displays, graphics tablets & 3D mice (devices for manipulating 3D objects and navigating scenes), etc. Workstations were the first Segment of the Computer market to present advanced Accessories and collaboration tools.
