The potential of IIoT extends across multiple sectors, enabling industries to become more competitive in
an increasingly connected world. As the adoption of IIoT grows, its impact will be felt not just in industrial
operations but also in the sustainability and resilience of global economies.
The IoT is revolutionising modern technology by integrating intelligence into everyday objects and industrial
systems. Its significance lies in its ability to create smarter, more efficient and interconnected solutions.
Notes
IIoT is revolutionising manufacturing
Smart factories, a hallmark of IIoT, utilise interconnected sensors and robotics to
automate and streamline production processes.
IIoT can track every stage of production, from raw material sourcing to finished product
delivery, ensuring transparency and reducing waste.
1.2 WHAT IS AN OPERATING SYSTEM (OS)?
Imagine turning on your computer to play a game or edit a document—all these actions are made possible
by an Operating System (OS). Without it, your computer would be unable to function effectively.
An Operating System is a system software responsible for managing all the resources of a computing device.
It serves as a bridge between the software and the computer hardware, ensuring smooth interaction between
the two.
The OS oversees the allocation and utilisation of resources and handles the overall operations of the computer.
It monitors and controls the execution of all other programs within the system, including both application
programs and other system software.
Examples of Operating Systems
Some of the widely used operating systems include:
For personal computers: Windows and macOS are the most popular operating systems used in desktops
and laptops.
Windows is developed by Microsoft and is widely used due to its compatibility with a large variety of
software and hardware.
The macOS, developed by Apple, is known for its smooth performance, strong security, and seamless
integration with other Apple devices.
Windows works on many types of hardware from different manufacturers, while macOS only runs on Apple
devices like MacBooks and iMacs.
For mobile devices: Android and iOS are the leading operating systems in smartphones and tablets.
Android, developed by Google, is open-source and is used by many mobile phone brands like Samsung,
Xiaomi, and OnePlus.
The iOS, developed by Apple, is only available on iPhones and iPads and is known for its smooth interface,
security, and app quality.
Android is more customisable and runs on various devices, while iOS is limited to Apple products but offers
tighter control and better privacy.
For servers and developers: Linux is a powerful and open-source operating system commonly used by
developers and in servers. It is known for its high security, stability, and flexibility. Many developers prefer
Linux for programming and system administration tasks.
