- Applications require faster machines to produce satisfactory results:
- A computer 's overall performance is determined by:
-its mircoprocessor internal clock speed.
- measured in units called GHz for billions of clock cycles pers second
- The architecture and word size of the processor
- Hi-end workstations and servers use 64-bit processors
-MOst PCs and macintoshes use 32-bit processors.
- Some embeded and special-purpose computers still use 8 and 16-bit processors.
