What is Caching?
Caching is the process of temporarily storing frequently accessed data or resources in a faster-to-access location, reducing latency and improving overall system performance by minimising the need to fetch the data from its original source with each request.

What is System Design?
System design is the process of defining and developing the architecture, components, modules, interfaces, and data for a system to meet specified requirements. It involves analysing user needs and constraints to create a plan for the construction, deployment, and maintenance of the system.

What is High Level Design?
High-level design refers to the architectural and conceptual overview of a system or software solution. It focuses on identifying major components, their interactions, and the overall structure of the system, providing a top-level understanding of how the solution will be implemented to meet the desired requirements.

What is Low Level Design?
Low-level design refers to the detailed design and implementation of individual components or modules within a system or software solution. It involves specifying the data structures, algorithms, interfaces, and code-level details necessary to realise the high-level design and achieve the desired functionality.
