Define SSRS and also talk about the SSRS architecture

SQL Server Reporting Services (SSRS) is a server-based software solution that creates Microsoft-developed reports. It’s used to create and distribute a range of interactive printed reports, and it’s controlled via a web-based interface. It supports and develops bespoke reporting apps using a web service interface.
SSRS’ architecture is made up of interconnected components. This scalable and flexible multi-tiered design is made up of several layers. Multiple computers can be served by a single installation.

Report Manager, Report Designer, the browser types supported by Reporting Services, Report Server, Report Server command-line tools, Report Server Database, Report Services Extensibility, and the data sources provided by Reporting Services are all part of the SSRS architecture.
