2016 KLAUS SCHWAB define 4 IR as “technological revolution that is blurring the lines between physical logical and digital spheres”
Difference between 3 IR and 4IR — — — — — — — — rapid change having good quality cheap price of processor having compatibility plus wireless network makes speedy as well
For Pakistan or for undeveloped country — — — — — — — — — — leap frog strategy is required means instead of learning precious method or old one learn new advance technology and applied on that part or entity in which you are good .that is suggested by Andrew Ng
THE HEART OF 4IR IS IoT
IoT DEFINITIONs :-
“Billions of physical devices around the world that are now connected to the internet, collecting, sharing and analyses of data.”
“The Internet of Things is a network of Internet connected devices that communicate embedded sensor data to the cloud for centralized processing.”
BENEFITS OF IoT (5 points)
- Improved Customer Engagement
- Technical Optimization
- Reduced Wastage
- Integrate and Adapt Business Model
- Better Business Decision
In short small size cheap processor intelligent design processor connectivity less power use and cloud computing make ease to adapt IoT
OVERVIEW OF HOW IoT WORKS
some IoT devices having micro-controller or silicon chip (rust programming language )(embedded system means no OS is required for them ) connected to IoT gate ways( linux Kubernetes and rust using LAN or WAN)IoT gate ways are basically edges do max processing or decision then pass the data to cloud computing (Kubernetes and rust) and then show it to final user (display is developed by (web assembly web )
Iot device and cloud services make the IoT works these two are most essential part of IoT
VALUE PROPOSITION
Iot * Big data = {unprecedented value in term of cost, growth, easy way to access people data }showing a big big alarming sign of privacy concern
chanllenges of IoT:
privacy , compliance , legacy market fragmentation new standards are need to be made underutilized data
A thing will be Iot if it have two things:-
intelligent micro controller and connectivity
Iot is design for specific purpose and its good in that specialty other than other functionality
Every IoT contain embedded system but not every embedded system is Iot.
Embedded system is cost and power critical small size do one thing as it is design to do specific task. In embedded system you have understand both the software and hardware, which makes it more difficult.
Microcontroller Characteristics
Architecture (ARM (HTM32 ), ESP32)
HTM32 (low bandwidth 4–128 bits small processing timer analog to digital converter Low power modes Communication protocol support(UART, I2C, SPI)
