Industry 4.0 terms in simple language:

Internet of Things (IoT):

Everyday objects (like machines, devices, and even things in your house) connected to the internet, allowing them to send and receive data. Think of your smart watch or a thermostat you can control with your phone.

Cloud computing:

Storing and accessing data and software over the internet instead of directly on your computer or a company server. It's like keeping your files in a big online storage space.

Artificial intelligence (AI):

Making computers think and learn like humans. This includes things like understanding language, recognizing images, and making decisions.

Additive manufacturing:

Building objects layer by layer from a digital design, often using 3D printing. It's like creating something by stacking very thin slices.

Augmented reality (AR):

Overlaying digital information and images onto the real world, often through a smartphone or special glasses. Think of apps that let you see how furniture would look in your room.

Cyber-physical systems (CPS):

Systems that combine physical processes with computing and communication. Imagine machines in a factory that can monitor themselves and communicate with each other.

Cobots:

Collaborative robots designed to work safely alongside humans in a shared workspace.
