In computer networking, a rich client, also known as a heavy, fat, or thick client, refers to a computer within a client-server network architecture that offers extensive functionality independently of the central server. Originally termed simply as a "client" or "thick client," a rich client stands in contrast to a "thin client," which heavily relies on server-side applications. A rich client is often distinguished by its rich user interaction capabilities.
Although a rich client still necessitates occasional network connections to a central server, it excels in performing various functions even when offline. On the other hand, a thin client minimizes processing tasks on the client side, relying on the server for processing and validation of input data each time.

In the context of a computer system, a rich client typically exhibits the following characteristics:

Local Processing: The client computer performs a substantial amount of the application logic and data processing on the user's device, reducing the need for constant communication with a server.

Rich User Interface: Rich clients often feature a sophisticated user interface with advanced graphics, interactive elements, and complex functionalities that enhance the user experience.

Offline Capabilities: A rich client can operate partially or fully offline, allowing users to access certain features and data even when disconnected from the network.

Resource Intensive: These clients typically require more resources such as memory, storage, and processing power compared to thin clients due to their local processing capabilities.

Independence from Server: Rich clients are less dependent on constant communication with a server, making them suitable for applications that require faster response times and reduced network latency.

The demand for low-cost rich clients in various industries is increasing significantly, as clients can save desk space and feature easy replacement or upgrade. Rich clients also help reduce power consumption and maintenance cost, and improve operation efficiency. More and more enterprises and governments use clients in their office work.

Giada, a leading tech company providing AIoT solutions for enterprises customers, has production line of rich clients, which are very popular among the customers.
One of the flagship model is BQ612. The rich client adopts Intel® LGA1700 Socket 12th/13th Gen. processors and supports rich I/O ports, including 8 x USB Type-A and dual LAN ports.
To enhance the durability, adaptability, and profitability of government and enterprise office solutions, Giada will release a new rich client, modeled BQ614. The new rich client features: Intel B760 chipset, DDR5 RAM up to 96GB, M.2 4G/5G and Type-C supporting DP1.4 output. Contact your account manager to obtain configuration details.
