Final answer:
To recover deleted data, first check your computer's trash or recycle bin. If not found there and you're on a Mac, use Time Machine or on Windows, check any backups available. If these don't work, try the 'Undo' option or contact technical support.
Step-by-step explanation:
If you've deleted some data from your computer and wish to restore it, the first step to consider is to check your computer's trash or recycle bin. This is a holding area for files and folders that are not yet permanently deleted from your computer. If the items are not in the recycle bin, and you're using a Mac, you may use Time Machine if you have set up this backup system. Time Machine allows you to restore previous versions of files and folders. On a Windows PC, use a backup if you have one created.
If the data is not found in either the recycle bin or through a backup, then the 'Undo' option can be utilized if it's immediately after the deletion. Lastly, if none of these options work, contacting technical support may help in recovering your data.
