the advantages of 8086 microprocessor over 8085A microprocessor is that 1)it is a 16 bit microprocessor 2)the disadvantages in 8085A microprocessor like low speed,limited number of registers,low memory addressing capability,less powerful instruction set have been overcome in 8086 registers
The advantages of downloading the main program into a microprocessor based system can be it can cause the system to run efficiently and the main program will be able to be easily accessed through the microprocessor system. Disadvantages can be due to errors they can happen due to system failure.
The advantages of 8086 microprocessor are: 1. It is a 16 bit processor 2. it can perform operation of 16 bit data at a time 3. It has a pipeline architecture 4. It has high sped then 8085 micro processor 5. Due to the two different parallel working of processors such as BIU and EU the time is saved
