When designing a system, one of the key steps is to identify the major components that make up the system. These components are the building blocks of the system and play a crucial role in its overall functioning.

In the context of high-level design, components can be thought of as modules or classes that encapsulate a specific set of functionality. They can be independent entities or can interact with other components to achieve the desired behavior.

When identifying components, it is important to consider the following factors:

• Functionality: What specific functionality does each component provide?
• Responsibilities: What are the responsibilities of each component?
• Dependencies: Which components depend on or interact with each other?

Let's consider an example to illustrate the process of identifying components. Suppose we are designing a social media platform. Some possible components of this system could be:

• User Management: Handles user registration, authentication, and profile management.
• News Feed: Aggregates and displays posts from users' connections.
• ___: Enables communication between users through private messages.
• Analytics: Collects and analyzes data related to user engagement and platform performance.

By identifying these components, we can gain a high-level understanding of the system structure and its various functionalities. This helps in further refining the design and ensuring modularity and maintainability.
