Which sentence contains an example of a networking problem? Hefin's Computer
Hefin works in a bank in London. As he arrives at the bank, he remembers the workload ahead of him. Many people are in line to make deposits.
Just as he reaches his desk, his colleague Janine calls out to him, asking him if he could lend her a hand with a spreadsheet because it isn't
performing a calculation. Hefin helps Janine with her spreadsheet and returns to his desk to switch on his computer. He sees that a number of
print jobs are waiting on his computer because his computer is the only one with an attached laser printer. He realizes that his printer is out of
ink, and so he puts in a refill. A customer standing at his desk wants to make a cash withdrawal. Hefin has to access his account to check
whether the customer's account has the required funds. However, Hefin can't access the computer with the customer database. So, he asks the
customer to come back later. He checks the cables, routers, and switches, and they seem fine. Now he has to call someone from the IT
department to fix the problem

The main part about version control is that you have a repository, which hosts files. any changes done to those files are recorded and, as such, can be reverted back. it is kind of like google drive/google docs (except not as "real-time autosave"). usually these files involve code. version control can usually record changes to files and the lines of code themselves.version control is used by developers, mainly with coding. this may include websites, software, video games, etc. it is very useful in terms of practicality and collaboration.  reverting back a previous version of a file is very useful in the coding/programming world. suppose a programmer adds in something new to a file, a code snippet or two. then he changes his mind because he does not like the feature he coded in (it does not work, inefficient, with version control, he can easily revert back the changes he made.  version control also makes it easier to collaborate. oftentimes, you can use an online, remote  repository such as github or bitbucket. a team of people  can each  connect their computers  to this repository and be synchronised with the source code.recording your changes is also for teamwork  as it tells you who did what. changes can be monitored as well.  online repositories (like  github) may also contain  features to talk about issues with the code, and you can  reference them in the changes.version control also allows you to have different versions of the same thing. there are open source projects where anyone able can contribute to the project; such collaborators are able to create a new version (a new "branch") from the master branch. in this new branch derived from the main master branch, one adds their code and such.  in time, the original developer will look at this branch; they can add all or some of those changes to the main branch if they approve.
