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 ...

Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

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 ...

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 (firearm)
The lock of a firearm is the mechanism used to initiate firing. It is generally used as a historical term, referring to such mechanisms used in muzzle loader, muzzle-loading and early breech loader, breech-loading firearms, as modern firearms uniformly fire by use of a firing pin to strike the rear of a Cartridge (firearms), cartridge. Side-lock refers to the type of construction, in which the individual components of the mechanism are mounted either side of a single plate. The assembly is then mounted to the Stock (firearms), stock on the side of the firearm. In modern firearm designs, the mechanism to initiate firing is generally constructed within the frame or Receiver (firearms), receiver of the firearm and is referred to as the Firing mechanism, firing or trigger mechanism. Hand cannon Hand cannon, the earliest of firearms, had arrived in Europe by 1338. These cannons were loaded from the muzzle loader, muzzle. The propellent charge is lit through a touch hole. A small ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (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 ...
