1. What is Microprocessor? Give the power supply & clock
frequency of 8085?
Ans:A
microprocessor is a multipurpose, programmable logic device that reads binary instructions from a storage device called
memory accepts binary data as input and processes data
according to those instructions and provides result as output. The power supply of 8085 is +5V and clock frequency in 3MHz.

3. What are the functions of an accumulator?
Ans:The accumulator is the register associated with the ALU
operations and sometimes I/O operations. It is an integral part of ALU. It
holds one of data to be processed by ALU. It also
temporarily stores the result of the operation performed by the ALU.
