Lock And Key
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the '' bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key to ...

Ormer Locklear
Ormer Leslie "Lock" Locklear (October 28, 1891 – August 2, 1920) was an American daredevil stunt pilot and film actor. His popular flying circus caught the attention of Hollywood, and he starred in ''The Great Air Robbery'' (1919), a screenplay about the mid-air piracy of a US airmail plane. In his next film, ''The Skywayman'', the plane crashed during a climactic dive, when the lighting team supposedly failed to douse the lights on cue, so Locklear was dazzled and flew blindly into the ground, dying instantly with his co-pilot Milton "Skeets" Elliott. The scene remained on the film. Early life Born in Greenville, Texas, Locklear was raised in Fort Worth. In 1911, Locklear met Calbraith Perry Rodgers, who landed his plane in Fort Worth to unclog a fuel line. After meeting Rodgers, Locklear became fascinated with aviation and airplanes. Shortly thereafter, Locklear and his brother constructed their own Glider (aircraft), glider. Upon completing his education, Locklear went ...

SIM Lock
A SIM lock, simlock, network lock, carrier lock or (master) subsidy lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks. This is in contrast to a phone (retrospectively called SIM-free or unlocked) that does not impose any SIM restrictions. Generally phones can be locked to accept only Subscriber Identity Module, SIM cards with certain International Mobile Subscriber Identity, International Mobile Subscriber Identities (IMSIs); IMSIs may be restricted by: * Mobile country code (MCC; e.g., will only work with SIM issued in one country) * Mobile network code (MNC; e.g., AT&T Mobility, T-Mobile US, T-Mobile, Vodafone, Bell Mobility etc.) * Mobile subscriber identification number (MSIN; i.e., only one SIM can be used with the phone) Additionally, some phones, especially Nokia phones, are locked by group IDs (GIDs), restricting them to ...

File Locking
File locking is a mechanism that restricts access to a computer file, or to a region of a file, by allowing only one user or process to modify or delete it at a specific time, and preventing reading of the file while it's being modified or deleted. Systems implement locking to prevent an ''interceding update'' scenario, which is an example of a race condition, by enforcing the serialization of update processes to any given file. The following example illustrates the interceding update problem: # Process A reads a customer record from a file containing account information, including the customer's account balance and phone number. # Process B now reads the same record from the same file, so it has its own copy. # Process A changes the account balance in its copy of the customer record and writes the record back to the file. # Process B, which still has the original ''stale'' value for the account balance in its copy of the customer record, updates the account balance and writes ...

Lock (database)
Record locking is the technique of preventing simultaneous access to data in a database, to prevent inconsistent results. The classic example is demonstrated by two bank clerks attempting to update the same bank account for two different transactions. Clerks 1 and 2 both retrieve (i.e., copy) the account's record. Clerk 1 applies and saves a transaction. Clerk 2 applies a different transaction to his saved copy, and saves the result, based on the original record and his changes, overwriting the transaction entered by clerk 1. The record no longer reflects the first transaction, as if it had never taken place. A simple way to prevent this is to lock the file whenever a record is being modified by any user, so that no other user can save data. This prevents records from being overwritten incorrectly, but allows only one record to be processed at a time, locking out other users who need to edit records at the same time. To allow several users to edit a database table at the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (computer Science)
In computer science, a lock or mutex (from mutual exclusion) is a synchronization primitive that prevents state from being modified or accessed by multiple threads of execution at once. Locks enforce mutual exclusion concurrency control policies, and with a variety of possible methods there exist multiple unique implementations for different applications. Types Generally, locks are ''advisory locks'', where each thread cooperates by acquiring the lock before accessing the corresponding data. Some systems also implement ''mandatory locks'', where attempting unauthorized access to a locked resource will force an exception in the entity attempting to make the access. The simplest type of lock is a binary semaphore. It provides exclusive access to the locked data. Other schemes also provide shared access for reading data. Other widely implemented access modes are exclusive, intend-to-exclude and intend-to-upgrade. Another way to classify locks is by what happens when the lock st ...

Grappling Hold
A grappling hold, commonly referred to simply as a hold that in Japanese language, Japanese is referred to as ''katame-waza'' ( "grappling technique"), is any specific grappling, wrestling, judo, or other martial art grip that is applied to an opponent. Grappling holds are used principally to control the opponent and to advance in points or grappling position, positioning. The holds may be categorized by their function, such as #Clinch hold, clinching, #Pinning hold, pinning, or #Submission hold, submission, while others can be classified by their anatomical effect: chokehold, headlock, joint-lock, or compression lock. Multiple categories may be appropriate for some of these holds. Clinch hold A clinch hold (also known as a clinching hold) is a grappling hold that is used in clinch fighting with the purpose of controlling the opponent. In wrestling it is referred to as the tie-up. The use of a clinch hold results in the grappling position#Stand-up grappling position, clinch. ...

Lock (rugby Union)
In the game of rugby union, there are 15 players on each team, comprising eight forwards (wearing jerseys numbered 1–8) and seven backs (numbered 9–15). In addition, there may be up to eight replacement players "on the bench", numbered 16–23. Players are not restricted to a single position, although they generally specialise in just one or two that suit their skills and body types. Players that play multiple positions are called "utility players". The Scrum (rugby), scrum (a contest used to restart play) must consist of eight players from each team: the "front row" (two props – a loosehead and tighthead – and a hooker), the "second row" (two locks), and a "back row" (two flankers and a number 8). The players outside the scrum are called "the backs": scrum-half, fly-half, inside centre, outside centre, two wings, and a fullback. Forwards compete for the ball in scrums and Line-out (rugby union), line-outs and are generally bigger and stronger than the backs. Props push ...

Lock (rugby League)
A rugby league team consists of 13 players on the field, with 4 interchange players on the bench. Each of the 13 players is assigned a position, normally with a standardised number, which reflects their role in attack and defence, although players can take up any position at any time. Players are divided into two general types, forwards and backs. Forwards are generally chosen for their size and strength. They are expected to run with the ball, to attack, and to make tackles. Forwards are required to improve the team's field position thus creating space and time for the backs. Backs are usually smaller and faster, though a big, fast player can be of advantage in the backs. Their roles require speed and ball-playing skills, rather than just strength, to take advantage of the field position gained by the forwards. Typically forwards tend to operate in the centre of the field, while backs operate nearer to the touch-lines, where more space can usually be found. Names and numbering ...

Lock Island
Lock Island is an island in the River Thames in England connected to Shepperton Lock, near Shepperton. Facing the attached by lock-gate bridge mainland is a hedge-lined lawn hosting a café, below and above zones of free short-stay moorings. The Thames River Police have a station on the island. Shepperton Canoe Club and Weybridge Mariners' Boat Club face part of the Weybridge side. The island is connected to Hamhaugh Island by a walkway across the main weir, in turn having a closed-access weir to Hamm Court, Addlestone. History Lock Island was uninhabited until the late 19th century, when some people from London moved there due to the unhealthy environment of the city. During the Blitz, a few families moved to the island and stayed there, with their descendants living in the few homes (all in the east of the island) such as Lock House. Environment The west of the island is undisturbed wilderness, and is home to a population of European water voles. A little of the island ...

Lock, South Australia
Lock is a town in the centre of Eyre Peninsula in South Australia. It is central Eyre Peninsula's main grain storage hub, as it is surrounded by a predominantly farming community, with emphasis on cereal crop production. The town has a hotel, caravan park, motel, supermarket, post office, police station, library, sporting complex, golf and bowling clubs and area school. At the 2006 census, Lock had a population of 290. History Although many nearby coastal towns were settled much earlier, Lock was not established until the 1860s due to the low rainfall and marginal conditions. Early settlers grazed sheep on vast tracts of natural vegetation for very low costs. Land settlement occurred in 1861, with settlements continuing further north over the next decades. A major change occurred in the area with the arrival of the Port Lincoln railway line in 1913. The area was serviced by a siding known simply as ''Terre Siding'' after one of the local properties. This was altered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
