Write protect: When set, the CPU cannot write to read-only pages when privilege level is 0 18: AM: Alignment mask: Alignment check enabled if AM set, AC flag (in EFLAGS register) set, and privilege level is 3 29: NW: Not-write through: Globally enables/disable write-through caching: 30: CD: Cache disable: Globally enables/disable the memory ...
In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array [1] key. [4] Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document.
This often increases the speed of image write operations by several times, at the cost of losing the simple sequential read/write semantics of normal memory. Additional bits which are provided on some computer architectures , such as AMD64 , allow the shadowing of ROM contents in memory (shadow ROM), and the configuration of memory-mapped I/O .
Microsoft Word is a word processing program developed by Microsoft.It was first released on October 25, 1983, [13] under the name Multi-Tool Word for Xenix systems. [14] [15] [16] Subsequent versions were later written for several other platforms including: IBM PCs running DOS (1983), Apple Macintosh running the Classic Mac OS (1985), AT&T UNIX PC (1985), Atari ST (1988), OS/2 (1989 ...
These mechanisms are intended to prevent only accidental data loss or attacks by computer viruses. A determined user can easily circumvent them either by covering a notch with adhesive tape or by creating one with a punch as appropriate, or sometimes by physically altering the media transport to ignore the write-protect mechanism.
System Restore is a feature in Microsoft Windows that allows the user to revert their computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems.
Microsoft Write is a basic word processor [1] included with Windows 1.0 [2] and later, until Windows NT 3.51.Throughout its lifespan, it was minimally updated. "Microsoft Write" also shares the name of a commercial retail release of Microsoft Word for the Apple Macintosh and Atari ST which is otherwise separate from this program.
Copy-on-write can be implemented efficiently using the page table by marking certain pages of memory as read-only and keeping a count of the number of references to the page. When data is written to these pages, the operating-system kernel intercepts the write attempt and allocates a new physical page, initialized with the copy-on-write data ...
