In computing and networking, aclientrefers to anapplication 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 requeststo a server.
The server processes the requestand sends back a response.
This architecture is widely used inweb applications, databases, and ServiceNowitself, whereclients interact with the ServiceNow platform (server) via a web browser or API requests.
In ServiceNow, theclienttypically refers toa user’s browser or an external system making requests via API calls.
Theserveris the ServiceNow instance, which processes requests and returns responses.
Client-side scripts(such asClient ScriptsorUI Policies) run on the user's browser, whileserver-side scripts(such as Business Rules and Script Includes) execute on the ServiceNow server.
How This Relates to ServiceNow:
A. Server→ A serverreceives requestsand processes them but is not the requesting entity.
C. Script→ A script is apiece of codethat executes certain actions but does not represent an entire system accessing a service.
D. Policies→ Policies definerules or behaviors(e.g., UI Policies, Data Policies) but do not access a remote service.
