SVN Terminology:
Repository: Repository is the central place of every control system where developers save their work. Repository not only saves work, it also saves history. Repository accessed over network it acts as a server and version control tool acting as a client.

Trunk: The Trunk is a directory where all the main development happens and is usually checked out by developers.

Tags: The tags directory is used to store named snapshots of the project. 

Branches: Branch operation is used to create another line of development. It is useful when you want your development process to fork off into two different directions.

Working Copy: Working copy is a snapshot of the repository is shared by all the team, but people do not modify directly. Instead each developer checkout working copy. The working copy is private workplace where developer can do their work with in isolated from the rest of the team.

Commit Changes: Commit is a process of storing changes from a private workplace to central server. After commit, changes are made available to all the team.

SVN Life cycle:
Create Repository:  Repository is the central place of every control system where developers save their work. Repository not only saves work, it also saves history. Repository accessed over network it acts as a server and version control tool acting as a client.

Check out: Check out operation is used to create a working copy from repository. Working copy is a private workplace where developers will do changes and later on submit that into repository.

Update: Update operation is used to update working copy. This operation synchronizes working copy with the repository. As any changes has committed by other developers into repository that changes will get reflect into your working copy when you have used update operation.

Perform Changes: After checkout one can do various operations to perform changes. Edit is the most common operation. One has done changes in existing file content. But, immediately these changes do not part of repository they are added to the pending changes-list and become part of repository after commit operation.

Rename operation changes the file/directory name. Move operation is used to move file/directory from one place to other place in repository tree.

Review Changes: When you checkout the working copy or update working copy then your working copy completely synchronized with the repository. But as you do changes to your working copy it becomes newer than the repository. It is very good practice review your changes before committing changes into repository.

Fix Mistakes: Let us suppose I have done changes in my working copy, but now I want to throw away these changes. In this situation revert operation will helpful. 

Resolve Conflicts: Conflicts will occur at the time of merging. Merge operation handles everything that can be done safely.

Commit Changes: Commit operation is used to commit changes from working copy to repository. This operation modifies the repository and other developers can see these changes by updating their working copy.
