External Hard Disk Drives

                 To keep your files and data safe, you can purchase an external hard
                 disk drive and copy the content of your computer on it. The initial
                 backup may take several hours, depending on the amount of data
                 and the speed of the HDD. Regular follow-up backups should be
                 conducted, as they will be quicker; the drive will only need to copy        External Hard Disk Drive

                 Online Backup Services

                 You can also backup your files to one of the online
                 backup services like Google Drive, Backblaze,

                 OneDrive, Dropbox, etc. from where your files
                 will always be accessible. The amount of storage
                 space provided by these services varies, and you
                 may need to pay a nominal monthly or yearly fee
                 for extra storage.

                    OTHER MAINTENANCE TECHNIQUES

                 To keep your computer running smoothly, it is important to keep files and folders uncluttered.
                 Cluttered or unorganised folders make it more difficult to find the files you need. Additionally,
                 unwanted files can eventually fill up your hard disk drive, which will make your computer slower
                 and more difficult to use.
                 There are a few things that you can do to delete unwanted files and improve your computer’s
                 performance:

                 ✶   Delete files: If you have unwanted files, you can delete them manually and move them into
                    the Recycle Bin, then empty the Recycle Bin.

                 ✶   Disk Defragmenter: Windows includes a Disk Defragmenter program. It scans the files
                    of your hard disk drive and rearranges them to free-up space. If your computer is working
                    slowly, running Disk Defragmenter can help to speed it up.
                 ✶   Disk Cleanup: Windows also includes a Disk Cleanup program. It scans your computer for
                    temporary files and other files that can be deleted. You can then delete these files to free up
                    space on your hard disk drive.

                    MALWARE

                 Malware is a malicious software designed to harm or exploit computer systems, networks, or
                 users. In Spanish, 'mal' is a prefix that means 'bad,' making the term 'badware,' which is a good
                 way to remember it.

                 The different types of malware are virus, worm, trojan horse, spyware, zombies, ramsomware,
                 rootkit and backdoor.
