The miniSD and microSD formats do not directly support a write protection notch, but they can be inserted into full-size adapters which do. [citation needed] When looking at the SD card from the top, the right side (the side with the beveled corner) must be notched. [citation needed] On the left side, there may be a write-protection notch.
Write once read many. Write once read many (WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device, excluding the possibility of data loss from human error, computer bugs, or malware.
Same build as microSD/microSDHC, but greater capacity and transfer speed, 32 GB and higher. Standard goes up to 2 TB (not compatible with older host devices). SDUC: 2018 not yet available Same build as SD/SDHC/SDXC, but greater capacity and transfer speed. Standard goes up to 128 TB (not compatible with older host devices). Memory Stick: Sony ...
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating gate MOSFETs.
Write blocking, a subset of write protection, is a technique used in computer forensics in order to maintain the integrity of data storage devices. By preventing all write operations to the device, e.g. a hard drive, it can be ensured that the device remains unaltered by data recovery methods.
Memory protection. Memory protection is a way to control memory access rights on a computer, and is a part of most modern instruction set architectures and operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug or malware within a process from ...
W^X ("write xor execute", pronounced W xor X) is a security feature in operating systems and virtual machines. It is a memory protection policy whereby every page in a process 's or kernel 's address space may be either writable or executable, but not both. Without such protection, a program can write (as data "W") CPU instructions in an area ...
