Why are registers in a microprocessor necessary if the same operations can be done using RAM only?
Chagz
Registers in a microprocessor are utilized, even though the same operations can be done using RAM, in order to boost performance. Registers, although adding cost and complexity, are very much faster than RAM. Its a balance between performance and cost.

Write a sequence of instruction to exchange two register contents using stack in 8086 processor?
To exchange two registers, say the BX and CX registers, in the 8086 using the stack, you can use...PUSH BXPUSH CXPOP BXPOP CX... Of course, this is for 16 bit operation. If you want 8 bit operation, you will need to do more than that, because stack operations are always 16-bit operations.
How many ic's used in the microprocessor?
we are using just one ic in a microprocessor
What are the operations of a microprocessor?
A microprocessor manipulates data in a computer system. The central processing unit acts as the brain of a computer and consists of one or more microprocessors made up of several thousand transistors on a single integrated circuit. The microprocessor works in conjunction with other parts of the computer to compute arithmetic and logic functions to handle tasks using an instruction set to perform all tasks within a computer.Microprocessor initiated operations are operations that the microprocessor itselp start.These are usually one of four operations.Memory ReadI/O operationMemory writeI/O read
What is the function of Registers in microcomputer system?
What is the function of Registers in microcomputer system?Another AnswerThe function of registers is the same in all computers. They are the fundamental binary interface between the internal and external structure of the CPU. All binary transactions between the CPU and its peripherals pass through registers. From the inside, they are the final periphery to the pins.
What is the first microprocessor of PC having 8 bit databus?

What are the main advantages of touch screen cash registers?
One advantage of touch screen cash registers is that you do not have to learn how to type using home row keys. Another advantage of touch screen cash registers is that they're easy to use.
What is the advantages and disadvantages of 8086 microprocessor?
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
What is microprocessor and explain the parts of microprocessor using block diagram?
Block diagramWorking:· CPU consists of three basic units: control unit, Arithmetic Logical Unit (ALU) and memory unit.· Input is given through the input devices to CPU.· Control unit controls communication within ALU and memory unit.· Decides which circuit is to be activated.· For reading instruction it uses Fetch-execute mechanism.· Control unit gets instruction from memory.· Control unit decides what to do of that instruction and transfers it to the ALU.· ALU performs various arithmetic operations like addition, subtraction, multiplication, division and logical operations like AND, OR, NOT, NAND etc. on that instruction.· Results of ALU are stored in the memory or resistor for its further operations.· After completing the instruction, stored results are passed to the output devices.· To synchronize all these operations CPU uses its own system clock.
