A strobe is a signal that defines a sampling period for another signal. Strobes are usually level sensitive. For example, an analog-to-digital converter often has a sample-hold circuit in front of it controlled by a strobe: "on" means sample, "off" means hold.
In signal processing the strobe-open time is called the "aperture". The fact that it is non-zero in real systems leads to an artifact called "aperture error".
A clock by contrast is edge-sensitive. Clocks too can have a kind of aperture error - jitter - which also causes artifacts in processing.
8 bit input is given to Intel 8085 microprocessor.

A microprocessor isn't input or output. It is the middle, it is the center. It takes input (from eg a keyboard) and generates output (for a eg a printer).

The communication between input and output device is called interfacing.
[url=http://www.dvdsuperdeal.com]A microprocessor[/url] is a multipurpose, programmable, clock driven, register based device that takes input and provides output.
There are binary patterns which when present on a microprocessor's input register, cause a fixed set of switching to occur within the processor, across a defined number of clock cycles. They comprise the instructions which cause the microprocessor to do things.
Numerical relays are all microprocessor based, but there are relays that take the advantage of microprocessor technology and are not fully numerical. In other words, if a relay is fully based on processing the samples of input signals it is numerical relay.

A microprocessor is part of a micro computer. A micro computer is a system which includes a microprocessor, instruction/data memory, input/output devices such as monitors, disk drives, keyboards, etc. , i.e. some way to store programs and read data and store and display results.
