Safe Semantics
Safe semantics is a computer hardware consistency model. It describes one type of guarantee that a Processor register, data register provides when it is shared by several Central processing unit, processors in a Parallel computing, parallel computer or in a network of computers working together. History Safe semantics was first defined by Leslie Lamport in 1985. It was formally defined in Lamport's "On Interprocess Communication" in 1986. Safe register has been implemented in many distributed systems. Description Safe semantics are defined for a variable with a single writer but multiple readers (SWMR). A SWMR register is safe if each read operation satisfies these properties: # A read operation not concurrent with any write operation returns the value written by the latest write operation. # A read operation that is concurrent with a write operation may return any value within the register's allowed range of values (for example, 0,1,2,...). In particular, given concurrency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typo Team/moss
A typographical error (often shortened to typo), also called a misprint, is a mistake (such as a spelling or transposition error) made in the typing of printed or electronic material. Historically, this referred to mistakes in manual typesetting. Technically, the term includes errors due to mechanical failure or slips of the hand or finger, but excludes ''errors of ignorance'', such as Orthography, spelling errors, or changing and misuse of words such as "than" and "then". Before the arrival of printing, the copyist's mistake or scribal error was the equivalent for manuscripts. Most typos involve simple duplication, omission, transposition, or substitution of a small number of characters. Fat-finger error, "Fat finger" typing (especially in the financial sector) is a slang term referring to an unwanted secondary action when typing. When a finger is bigger than the touch zone, with touchscreens or keyboard (computing), keyboards, there can be inaccuracy and one may hit two keys in ...
