A front-end system is part of an information system that the user directly accesses and interacts with to receive or utilize the back-end capabilities of the host system. It allows users to access and request the benefits and services of the underlying information system. The front-end system can be a software or hardware application or combination as well as network resources
How a front end system works
A frontend system is mainly used to send questions and requests, and receive data from the host system. It serves or provides users with the ability to interact with and use an information system. Typically, front-end systems have very limited computational or business logic processing capabilities and are based on the data and functions of the host system. However, some advanced-level front-end systems maintain copies of the data, such as a duplicate of each transaction, which is sent to the back-end system.
A front-end system may include or consist of text or graphical user interface (GUI) and/or a front-end client application that is connected by the back-end system.
Frontend vs. Backend
Front-end and back-end systems are the starting and ending points of any software or network processing system. The front end, which is the hardware device that protects the computer from traffic, is placed at the outer boundary of the network link. The back end is composed of routers and/or servers (e.g. database and web). Front ends and back ends have a very wide scope of application, the front end of the application receives direct input from the user, and the back end collects and manages the data entered by the user.
