Microprocessor(Does your CPU uses 3 GHz of processor or 3.85 GHz, more the frequency of microprocessor the faster it processes the information. 1 Mhz means it can perform 1000 instruction in 1 sec. 1 Ghz = 1000Mhz.)

Now a days processors comes with core. More the core faster the cpu processes information.

Examples:

Pentium III 2.7Ghz Dual core

Hard Drive capacity.

Cache memory.
