TeamViewer is a simple and fast solution for remote control of applications, desktop sharing, and file transfer behind any firewall. To connect to another computer, all you need to do is run TeamViewer on both machines at the same time without installation (you can also choose to install, and after installation, you can set up the boot to run).

Pros: When something went wrong with my computer that I couldn’t solve at all, I can turn to my friends and use Teamviewer to help me out. My friend can control my computer remotely with my permission so that he can help me diagnose what is wrong with my computer. This is very convenient for me because when I was in the coding class before, I had some coding problems that I didn’t understand. I could also ask my friend for help, and he could immediately teach me.

Cons: If the personal version is tested for commercial use, a trial period will be added. Sometimes it may disconnect. And the commercial version is expensive.
