Dynamic RAM
I/O ports
PIO 8255
D/A and A/D converters
Stepper motor interfacing
Control of high power devices 

The 8086 Microprocessor has a 16-bit data bus, so it can read from or write data to memory and ports either 16-bits or 8-bits at a time. It also has a 20-bit address bus, so it can address any one of 220 or 1,048,576 memory locations. 
The microprocessor supervises the activity of the controller, and intervenes on each transfer of data by executing respective instructions of data read or write from (to) the controller. 
To execute a program, the microprocessor: Reads each instruction from memory, Interprets it, and Executes it. 
This sequence is continued until all instructions are performed.
