írásvédelmi

Írásvédelmi is a Hungarian term that translates to "write protection" in English. It refers to a mechanism that prevents data from being modified or deleted on a storage medium. This protection can be implemented in various ways depending on the type of storage device.

For physical media like floppy disks, write protection was often achieved through a physical switch or tab. Sliding this switch into the "locked" position would prevent writing to the disk. Similarly, some CDs and DVDs had write-protected versions, meaning data could only be written to them once.

In the context of digital storage, write protection is usually a software-based setting. This can be applied to individual files or folders, preventing accidental or malicious changes. Operating systems often provide options to set files as read-only, which is a form of write protection. Some storage devices, like USB flash drives or SD cards, may also have a software-enabled write protection feature that can be toggled through device settings or dedicated utilities.

The primary purpose of write protection is data integrity and security. It ensures that important files remain unchanged, prevents accidental deletion of critical data, and can be a security measure against malware that attempts to modify or encrypt files. While it offers safety, users must remember to disable write protection when they need to modify or add data to a storage medium.
