what is a microprocessor? and what is it's work?

A microprocessor is a processing unite which process the data according to our work. it is fabricated on a small chip who’s size is decreasing day by day.

It is made of transistors through the size of transistor is decreasing that's why the size of microprocessors, microcontroller and, chips are also decreasing.

A microprocessor is a small processor. it processes the data which program is currently running in the system. a microprocessor consists of ALU(Arithmetic and Logical Unit), register sets(Array), and control unit.

IT takes the input  while processing it need some memory to fetch the related data and saves the output and gives us the output



processes the data in an instruction cycle.

there are three stapes in an instruction cycle.

1. Fetch

In this stape, the microprocessor fetches(reads) the codes wherever it is saved in the memory (probably copied to the main memory(RAM) before processing)

2. Decode

After fetching the data it decodes it. simply decoding is a process in which the computer let it know that what is going to be performed and what actions are to be taken by the system hardware.

3. Execute

decoding the data when the system knows that what to be done by the hardware of the system it simply execute those instructions.

Features of a Microprocessor

Here is a list of some of the most prominent features of any microprocessor −

Reliability

 − The failure rate of an IC in microprocessors is very low, hence it is reliable.

Power efficiency

 − Microprocessors are manufactured by using metal-oxide semiconductor technology, which has low power consumption.

Cost-effective

The microprocessor chips are available at low prices and results in its low cost.

Size

− The microprocessor is of small size chip, hence is portable.

Usability

− The microprocessors are versatile as we can use the same chip in a number of applications by configuring the software program.

Apple watch series 4 launched : All new from ECG monitoring to fall detection.

the first product to unveiled at Apple event was the all-new Apple watch series 4,
The Apple Watch Series 4 is waterproof and comes with LTE and Bluetooth 5.0 connectivity. Even with added features, the new Series 4 will give the same 18-hours battery life as seen on its predecessor. It comes in Silver, Space Black, and Gold color options. Talking about the pricing, the Apple Watch Series 4 will be retailing from $399. The Apple Watch Series 4 cellular variant will be available from $499.
Here are the things about which we are going to talk about.


Display:

new Apple Watch Series 4 comes in 40mm and 44mm sizes and offers over 30% larger display. They also got a new watch face which shows up to 8 complications. As seen in the leaks, the bezels look very small compared to their predecessors.


UI (Redesigned)

The Apple Watch Series 4 comes with a redesigned Watch OS 5 which makes use of the updated hardware to deliver more features than ever before.


Hardware:
 The new Apple Watch Series 4 is powered by a fourth gen processing unit which Apple calls S4 which is made up of a 64-bit dual-core processor and a new GPU. Thanks to the updated hardware, the new Apple Watch is claimed to be two times faster than the older generation.


The big hype ECG monitoring:

The first ever smart watch to come with built in ECG monitoring app by apple it has a new electrical heart rate sensor capable of delivering FDA approved ECG test results.


Fall detection:

The all new apple watch series 4 has a combined setup of accelerometer and gyroscope sensors that detect the fall and initiate sending messages to your loved ones in any case of emergency.
