Source Control Management (SCM)

Question 5

A command that can detect that there were changes made to the file and will do its best to apply the changes

Answer 5

patch
A patch in Git is a file that contains a set of changes (diffs) between two versions of a repository. Patches are useful for sharing changes without using a central repository or for applying changes from one branch or repository to another.

Question 6

A stage where changes have been made to a file, but the have not been stored or committed

Answer 6

modified files

Question 7

A file maintained by Git that contains all the information about what files and changes are going to go into the next commit

Answer 7

git staging area

Question 8

A log that displays commit messages

Answer 8

git log

Question 9

A database for a Git project that stores the changes and the change history

Answer 9

Git directory

Question 10

A configuration file that specifies the mappings between IP addresses and host names in your network

Answer 10

dns zone file

Question 11

A command to find the differences between two files

Answer 11

diff

Question 12

A stage where the changes made to files are safely stored in a snapshot in the Git directory

Answer 12

commit files

Question 13

A command to make edits to multiple files and treat that collection of edits as a single change

Answer 13

commit

Question 14

Git Directory vs. Working Tree vs. Staging Area

Answer 14

• Git directory: contains the history of all the files and changes
• Working tree: contains the current state of the project, including any changes that we’ve made
• Staging Area: contains the changes that have been marked to be included in the next commit
• When committing new files or changes with git commit, the user is asked to provide a commit message because you cannot commit with an empty commit message

Question 15

Describe important aspects of git

Answer 15

• VCS created in 2005 by Linus Torvalds (he started the Linux kernel)
• Free open source system available for installation
• Every person can contribute to a repository has a full copy of repository on their own development machine
• Can work as a standalone program as a server and as a client

Question 16

Explain what a VCS version control system is

Answer 16

• Automates the process of version control, tracks changes to a file or set of files over time so that you do not have to manage file versions manually or with custom automation script, keeps a complete history of your code and other files, allowing you to return to a previous version if needed. Example: Git and GitHub
• Git helps us keep track of our changes and also how we can use it to collaborate with others or avert changes
• Commit: can make edits to multiple files and treat that collection of edits as a single change
• Repositories: centralized digital storage that developers use to make and manage changes to an application’s source code

Question 17

Difference between linear sequence and non-linear commits

Answer 17

linear sequence
commits in 1 branch

non linear commits
commits on different branches

Question 18
