Git is a distributed version control system that is widely used in software development to manage source code and track changes made to it over time. It was developed by Linus Torvalds in 2005 and is now maintained by a community of developers.
Git allows multiple developers to work on the same codebase simultaneously and keep track of changes made by each individual. Each developer can create a local copy of the code repository and make changes to it independently. Git then allows these changes to be merged together into a single version of the code that incorporates all the modifications.
Git stores changes to the code as a series of commits, each of which records a snapshot of the code at a particular point in time. Git also allows developers to create branches, which are separate lines of development that can be merged back into the main codebase when they are complete.
