The processing speed depends on DATA BUS WIDTH.
High-density n- type Complimentary Metal Oxide Silicon field effect transistor.
The processor made of PMOS / NMOS / HMOS / HCMOS technology is called 1st / 2nd / 3rd / 4th generation processor, and it is made up of 4 / 8 / 16 / 32 bits.
In primary storage device the storage capacity is limited. It has a volatile memory. In secondary storage device the storage capacity is larger. It is a nonvolatile memory. Primary devices are: RAM / ROM. Secondary devices are: Floppy disc / Hard disk.
If for a short period of time circuits goes to some different logic level then it is supposed to have then it is called static hazard.e.g. If the final logic value of output of a given circuit becomes one even if it is supposed to be zero then it is called Static-0 Hazard and vice versa. Dynamic Hazard is the one in which the circuit output goes to some other logic level more than once then finally settling down to some appropriate level.
