Distributed revision control synchronizes repositories by transferring patches from peer to peer. There is no single central version of the codebase instead, each user can download a working copy and the full change history. Hence not requiring to be connected to the server all the time. Example : GIT

It is a version control where there is a single central repository hosted on a server. This server is expected to have the latest code and expects all its clients to contribute by being connected to the server always.

Git mainly uses three different types of objects to hold information about a repository BLOB – binary form of the actual data TREE – It contains pointers to the objects COMMIT – Commit object contains information about the author, date, hash id made for a particular commit

It is a workflow that can be used to maintain large projects and it mainly consists of The master branch is always ready for live release with everything production-ready. The Hotflix branches help in quick patching of production releases. The Develop branch helps in merging of all feature branches and also performs all the tests. The Feature branch implies a unique branch for every new feature. The feature branch could be pushed to the development branch just like their parent branch.

git rebase [new-commit]

When plannning to cascade/notify new activities on git server to a different tool like jenkins, git webhook is used. the webhook contains information about the activity (ex: push on the server).
