What does layers mean in ict?

In Information and Communication Technology (ICT), "layers" typically refer to the different levels of abstraction in a system architecture. Each layer serves a specific function and communicates with adjacent layers, facilitating modular design and simplifying complex processes. Common examples include the OSI model in networking, which defines layers for data transmission, and software architecture layers that separate user interface, business logic, and data management. This layered approach enhances maintainability, scalability, and interoperability.
