Can you explain what is meant by 'thick client' in application architecture?

A "Thick Client" is a type of client application that performs most of the data processing and business logic on the client side rather than on the server. In such architecture, the client application contains significant functionality, including the interface, data processing, and logic, and can operate autonomously or with minimal interaction with the server.

Example: a desktop application for document editing that saves files locally and synchronizes with the server only when necessary.

Advantages of a thick client:

• Less load on the server
• Fast interface response
• Ability to work offline

Disadvantages:

• More difficult to update and maintain
• Requires more resources on the client

In contrast, a "Thin Client" is minimally loaded with logic and mainly displays data received from the server.
