Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer. 

Question

(a) Using the 8255 PPI, an 8-bit ADC interfaced to 8086 MPU, write
an assembly program such that Port-B of 8255 for transferring digital
data output of ADC to the CPU and Port-C for EOC & SOC pulse
signal. Assume that an analog input is present at channel-4 of the
ADC. Assume Port-C address to be 34H and describe the hardware
schematic.
