An RW lock allows concurrent access for read-only operations, whereas write operations require exclusive access. This means that multiple threads can read the data in parallel but an exclusive lock is needed for writing or modifying data. When a writer is writing the data, all other writers and readers will be blocked until the writer is ...
The write is one of the most basic routines provided by a Unix-like operating system kernel. It writes data from a buffer declared by the user to a given device, such as a file. This is the primary way to output data from a program by directly using a system call. The destination is identified by a numeric code.

The write permission grants the ability to modify a file. When set for a directory, this permission grants the ability to ...
In information technology, a write-only memory (WOM) is a memory location or register that can be written to but not read.In addition to its literal meaning, the term may be applied to a situation when the data written by one circuit can be read only by other circuitry.
A lock file is often the best approach if the resource to be controlled is not a regular file at all, so using methods for locking files does not apply. For example, a lock file might govern access to a set of related resources, such as several different files, directories, a group of disk partitions, or selected access to higher level ...
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.
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.
The ISO 216:2007 is the current international standard for paper sizes, including writing papers and some types of printing papers. This standard describes the paper sizes under what the ISO calls the A, B, and C series formats. [2] Not all countries follow ISO 216.
