Thick Client refers to a computer that relies on its processing power, and it doesn’t connect to any powerful server. It works just like independent device. Regular computers are in this category as they capably run applications locally without the need for external help. Thick client is mostly used at home as a personal computer. Also, most of the companies are still using the thick client in their facilities.



Thin Client is a computer that depends heavily on a more powerful computer, which stores all the main applications and data. Thin client connects to a server to access its resources because the thin client doesn’t have a hard disk and all data are stored into the server computer. Thin client computer power and speed depend on server’s specifications. The thin client computer uses more secure facilities, for example, a bank. The bank has to secure all sensitive data and doesn’t take any risk to hack any individual computer.



Web Client is entirely different from the first two client types. Web client connects to web browsers and runs the application on the server side with using a web browser. For example, Chromebook is one of the web clients. Web client computer is used mostly to give flexible access to their users. For example, most of the universities start the web application to give access to their students to use some school applications with using web browsers.
