This happens because computers are set up differently. You might have a different operating system, a different version of a programming language, or different background software running. When a website or app breaks because of this, developers can lose hours or even days trying to figure out what the problem is. To solve this, developers came up with ways to isolate software. Instead of installing an app directly onto your main computer, you put it inside a protective bubble . This bubble tricks the software into thinking it has its own private space, with exactly what it needs to run, so it won't mess with the rest of your system. There are three main tools we use to create these bubbles; Virtual Environments , Virtual Machines (VMs) and Docker .…
