Hi @Sandhya Shinde,
To answer your question specifically - as @Dr Atul G- LNG has mentioned, in a 'vanilla' (Baseline Out Of Box instance) ServiceNow pre-configures 2 generic Knowledge Bases: IT and Knowledge
- The 'IT' Knowledge Base is 'demo' Knowledge Base intentnded for users for specific companies and specific users. Note - against a Knowledge base you can configure who can view or see the KB. This can be configured by role, by group or specific user criteria.
- The 'Knowledge' Knowledge Base is again pre-configured for 'Knowledge' users. Any user can read this Knowledge Base and user with Knowledge roles can contribute (Add, edit and publish) to this Knowledge Base
There's a great community link from ServiceNow employee @Ashley Snyder who walks through 'Getting started with Knowledge Management' with some vids and step by step guides - I recommend you check that link out.
Don't forget, the 2 Knowledge Bases pre-configured are just to help guide you. You can create your own and as you implement or turn on more modules such as Customer Service Management or HR, these come with pre-configured Knowledge Bases for you.

Thanks, Robbie
