In computing and networking, a client refers to an application or system that accesses a remote service or another computer system (known as a server). The client-server model is a fundamental concept in computing, where:
A client sends requests to a server.
The server processes the request and sends back a response.
This architecture is widely used in web applications, databases, and ServiceNow itself, where clients interact with the ServiceNow platform (server) via a web browser or API requests.
How This Relates to ServiceNow:
In ServiceNow, the client typically refers to a user's browser or an external system making requests via API calls.
The server is the ServiceNow instance, which processes requests and returns responses.
Client-side scripts (such as Client Scripts or UI Policies) run on the user's browser, while server-side scripts (such as Business Rules and Script Includes) execute on the ServiceNow server.
Why Other Options Are Incorrect:
A . Server → A server receives requests and processes them but is not the requesting entity.
C . Script → A script is a piece of code that executes certain actions but does not represent an entire system accessing a service.
D . Policies → Policies define rules or behaviors (e.g., UI Policies, Data Policies) but do not access a remote service.
