A sandbox in computer terms is a virtual playground where apps, browsers, or programs can run wild—but they can’t escape the yard. It’s like putting a squirrel inside a hamster ball: it can bounce around, but it’s not leaving that plastic sphere to chew your couch. Most modern browsers (Chrome, Firefox, Edge) use sandboxes to isolate tabs or plugins so any virus or crash stays trapped.
If a malicious website tries to break into your bank password while sandboxed, it’s basically a frustrated raccoon inside a locked garbage bin. It can scream and rattle, but it’s not getting to the steak inside your freezer. The sandbox keeps your whole system safe from whatever digital chaos happens in that one tab.
