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.
The tape can only be recorded onto (or recorded over) when this tab is in the "REC" position. This is an improved version of the VHS write-protect tab, which prevents erasure after it has been broken off, requiring covering with adhesive tape or filling with an obstruction to remove the write protection.
Executable-space protection. In computer security, executable-space protection marks memory regions as non-executable, such that an attempt to execute machine code in these regions will cause an exception. It makes use of hardware features such as the NX bit (no-execute bit), or in some cases software emulation of those features.
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 affecting other ...
The r, w, and x specify the read, write, and execute access respectively. The first character of the ls -l display denotes the object type; a hyphen represents a plain file. The script findPhoneNumbers.sh can be read, written to, and executed by the user dgerman ; read and executed by members of the staff group; and only read by any other users.
Copy protection for computer software, especially for games, has been a long cat-and-mouse struggle between publishers and crackers.These were (and are) programmers who defeated copy protection on software as a hobby, add their alias to the title screen, and then distribute the "cracked" product to the network of warez BBSes or Internet sites that specialized in distributing unauthorized ...
In write-back mode, writes are written to the CPU's cache and the cache is marked dirty, so that its contents are written to memory later. Write-combining allows bus write transfers to be combined into a larger transfer before bursting them over the bus to allow more efficient writes to system resources like graphics card memory. This often ...
