To "erase" or "delete" means to remove something completely so that it no longer exists in a particular space. For example, when you erase a pencil mark from a piece of paper, you are making it disappear, leaving the paper clean. Similarly, when you delete a file from your computer, it is taken out of your storage, making it inaccessible. In the digital world, erasing can also refer to removing data from devices like smartphones or tablets. When you delete an app, for instance, it is no longer on your device, freeing up space for new applications. This process helps keep your device organized and efficient.
