PC's and MAC's Single user operating system Monotasking operating system Limited (expensive) disk space availabililty Usually no native networking Availability of resource sharing systems Very good dedicated user interface

Workstations Multitasking operating system Multiuser operating system Higher disk space availability Native networking Resource sharing by means of standards Good (distributed) windowing interface A lot of CPU dedicated to the user interface

Mainframes Multitasking operating system Multiuser time-shared operating system High (cheap) disk space availability No native multi-vendor networking Resource sharing by means of standard protocols Weak user interface Little CPU used for the user interface
