Microprocessor consists of only a Central Processing Unit, whereas Micro Controller contains a CPU, Memory, I/O all integrated into one chip. ... Microprocessor uses an external bus to interface to RAM, ROM , and other peripherals, on the other hand, Microcontroller uses an internal controlling bus.
What is the major difference between a microprocessor and microcontroller Mcq?
| Microprocessor Microcontroller | 3) Memory and I/O has to be connected externally, so the circuit becomes large. Memory and I/O are already present, and the internal circuit is small. | 4) You can’t use it in compact systems. You can use it in compact systems. |

What is microprocessor explain with diagram?
Computer’s Central Processing Unit (CPU) built on a single Integrated Circuit (IC) is called a microprocessor. A digital computer with one microprocessor which acts as a CPU is called microcomputer. ... The microprocessor contains millions of tiny components like transistors, registers, and diodes that work together .
What is difference between processor and microprocessor?
Microprocessors are the circuitry that surround the CPU. The microprocessor is more than the CPU . It contains other processors, for example, the graphics processor unit. ... So a CPU is part of a microprocessor, but a microprocessor is more than the CPU.
Why microcontroller is called Heart of embedded system?
Microcontroller is a heart of an embedded system. Microocntroller can be easily interfaced to external peripheral devices like ADC , DAC, serial ports, Bluetooth, Wi-Fi, etc. The interfacing procedure of the microcontroller is very fast.
What is microprocessor and its types?
There are three types of microprocessors namely, CISC, RISC, and EPIC . A microprocessor is basically the brain of the computer. ... We can also call it simply a processor or CPU. Furthermore, a microprocessor is basically a computer processor that is mounted on a single IC (Integrated Circuit).
What is microprocessor explain with example?
Microprocessor, any of a type of miniature electronic device that contains the arithmetic, logic, and control circuitry necessary to perform the functions of a digital computer’s central processing unit . ... The first microprocessor was the Intel 4004, which was introduced in 1971.
Which is faster microprocessor or microcontroller?
As all the peripheral of microcontroller are on single chip it is compact while microprocessor is bulky. ... Processing speed of microcontrollers is about 8 MHz to 50 MHz, but in contrary processing speed of general microprocessors is above 1 GHz so it works much faster than microcontrollers.
Which is the first microcontroller Mcq?
Which is the first microcontroller? Solution: Explanation: TMS1000 is the first microcontroller which was done in April 1971 but Intel 4004 was designed in November 1971.
What are the applications of microcontroller?
- Light sensing & controlling devices.
- Temperature sensing and controlling devices.
- Fire detection & safety devices.
- Industrial instrumentation devices.
- Process control devices.
Why processor is called microprocessor?
It is so called because this device comprises of transistors which are small in size (micro-meter) . The word micro is used in electronics and in science generally, to mean One-millionth or 10^-6. It has also used to denote something very small like a very small processor or microprocessor.
Is Ram a microprocessor?
The motherboard carries the microprocessor (CPU), RAM , BIOS ROM, bus controllers and I/O interfaces. The CPU communicates with the main system chips via a shared set of address and data bus lines. The microcontroller provides most of the features of a conventional microprocessor system on one chip.
What are the components of microprocessor?
- Control Unit.
- I/O Units.
- Arithmetic Logic Unit (ALU)
- Registers.
- Cache.
What are the applications of embedded system?
- Motor and cruise control system.
- Body or Engine safety.
- Entertainment and multimedia in car.
- E-Com and Mobile access.
- Robotics in assembly line.
- Wireless communication.
- Mobile computing and networking.
What is the purpose of embedded system?
An embedded system is a small computer that forms part of a larger system, device or machine. Its purpose is to control the device and to allow a user to interact with it . They tend to have one, or a limited number of tasks that they can perform.
Which is heart of embedded system?
Processor is the heart of an embedded system. It is the basic unit that takes inputs and produces an output after processing the data.
