What is the main task of the Git version control system and why is it used in the development process?

Git is a distributed version control system, whose main task is to track changes in source code and other project files. It allows developers to save change history, work in parallel on different parts of the code, merge work results, and revert to previous versions if necessary.

Git is used for:

• Collaborative work among multiple developers without conflicts.
• Storing a complete change history for analysis and recovery.
• Branching for developing new features or fixing bugs separately from the main branch.

Example of basic commands:

git init       # initialize repository
git add .      # add changes to the index
git commit -m "description"  # save changes
git push       # send changes to a remote server
