STACK operation in 8085 microprocessor.
The stack is a reserved area of the memory in RAM where temporary information may be stored. An 8-bit stack pointer is used to hold the address of the most recent stack entry. This location which has the most recent entry is called as the top of the stack.
When the information is written on the stack, the operation is called PUSH. When the information is read from the stack, the operation is called POP. The stack works on the principle of Last in First Out or Fist in Lat Out

What is the position of the stack pointer after the pop instruction in Intel's 8085 and 8086?
In Intel's 8085 microprocessor, the stack pointer (SP) is decremented by 2 after a POP instruction, as it retrieves a 16-bit value from the stack. In the 8086 microprocessor, the stack pointer is decremented by 2 as well, due to the same reason of retrieving a 16-bit word from the stack. Thus, in both architectures, the stack pointer points to the next available address in the stack after the POP operation.
Why the name 8085 Why the name 8085 for microprocessor?
8085 is a microprocessor designed by Intel
What is the purpose of the RRC instruction in 8085 microprocessor?
We can implement "Divided by '2' " operation by using RRC.
What do '8085' in 8085 Microprocessor signify?
The '8085' in the 8085 microprocessor is the designation given to the microprocessor by Intel. The '5' means it is a single power supply (5 volt) version of the 8080, with enhancements.
What power supply is used in microprocessor 8085 programming?
+5v necessary for microprocessor 8085.
What is the Overview of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel Co.
Why microprocessor 8085 has 16 bit address lines?
Because that's how Intel designed it. The 8085 is an 8-bit computer operating on a 16-bit address space.
Why stack is decremented by 2 in push instruction in 8085?
In the 8085 microprocessor, the stack is decremented by 2 during a push instruction because each push operation stores 16-bit data (2 bytes) onto the stack. The stack grows downwards in memory, so to accommodate the new data, the stack pointer (SP) is first decremented by 2 before the data is written to the memory location pointed to by the SP. This ensures that both bytes of the data are stored correctly in consecutive memory locations.
