What is the Difference Between Shutting Down and Restarting?

Restarting and shutting down have different purposes and should be used in different situations. As it always goes, someone in IT will always ask you first if you have restarted your computer if something doesn't seem right. That is because most issues can be resolved by restarting your computer, rather than shutting down. So, what is the true difference between shutting down and restarting and how do you know which one to do in certain situations?

What Does Shutting Down Do?

A shut down ends all processes, applications, and turns your computer off completely which removes power from Random Access Memory (RAM) and computer hardware like USB connected devices and displays.

Situations where you should shut down:

1. When you won’t be using it for a couple days

2. To save battery

3. When you are done working for the day

What does Restarting do?

A restart will shut down all of the computer's processes, clear the Random Access Memory (RAM) and clears the cache so that you can get a clean start when your computer boots up again.

RAM handles short terms tasks and data, so your computer benefits from restarting since it clears out random and unimportant data that can negatively impact your computer's performance.

Cache is temporarily stored copies of data from frequently used memory locations that aides in data retrieval.

1. After doing an update, software or firmware related

2. If an application is not working properly

4. Your fan is spinning and is very loud

A restart can take anywhere a couple seconds to a couple minutes.
