Stairway to SQL Server Replication: Level 3 - Transactional Replication – The Publisher
The Publisher is the database where all
replicated data originates. Each Publisher can have multiple publications
defined within it. Each publication contains a set of articles that all need to
reside in a single database. Each article corresponds to all or part of a single
database object. A single database object can map to an article in more than one
publication.

Stairway to SQL Server Replication: Level 4 - Transactional Replication – The Subscriber
The Subscriber is the server where all the changes that are published by replication get delivered to. Every publication needs to have at least one subscriber, but a publication can have many subscribers. This level assumes that you have followed the first three levels and that you have a publication set up, to which you can subscribe.

The Fundamentals of SQL Server Replication by Sebastian Meine
Many of my clients need to make data that lives on one server available on another server. There are many reasons for such a requirement. You might want to speed up cross-server queries by providing a local copy of the data. Or you might want to make the data available to resource intensive reporting queries without impacting the OLTP load, maybe even with an intentional delay so you're always reporting against complete days only. Finally, you might be looking to implement high availability. In all these situations, SQL Server Replication is a viable option to look at when planning for the implementation of such a requirement.
