oneref date February 2012 sections date February 2012 Merge Program state discuss Talk Statecomputerscience Merge date March 2010 In computerscience and automata theory , a state is a unique configuration of information in a program or machine. It is a concept that occasionally extends into some forms of System programming systems programming such as Lexical analysis lexer s and parser s. Whether the automaton in question is a finite state machine , a pushdown automaton or a full fledged Turing machine , a state is a particular set of instructions that will be executed in response to the machine s input. The state can be thought of as analogous to a practical computer s main memory. The behavior of the system is a function of the definition of the automaton, the input, and the current state. Following states are distinguished Compatible states are states in a state machine that do not conflict for any input values. Thus for every input, both states must have the same output, and both ... before it.

Input In computerscience the general meaning of input is to provide or give something to the computer, in other words the state or act of a computer or a component of computer or relevant device being accepting something from the user or from a device or from a software either automatically or manually is called Input. We categorize computer devices as input devices due to the fact that we use these devices to send instructions to the computer, we are sending our Input to the computer, some common examples of computer input devices are Mouse computing Mouse Keyboard computing Keyboard Microphone We may also call some inner parts of the computer as input components to the other components, like the power on button of a computer is an input component for the processor or the power supply. Because it takes user input and sends it to other components for further processing. In many computer languages the keyword Input is used as a special keyword or function, like in Visual Basic, the Input is used to get text input from the user. Category Input output ... more details

Unreferenced date May 2011 In computerscience , synchronization refers to one of two distinct but related concepts synchronization of process computerscience processes , and synchronization of data. Process synchronization refers to the idea that multiple processes are to join up or handshake at a certain point, so as to reach an agreement or commit to a certain sequence of action. Data synchronization refers to the idea of keeping multiple copies of a dataset in coherence with one another, or to maintain data integrity . Process synchronization primitives are commonly used to implement data synchronization. Thread or process synchronization Thread synchronization or serialization, strictly defined, is the application of particular mechanisms to ensure that two concurrently executing thread computerscience threads or process computerscience processes do not execute specific portions of a program at the same time. If one thread has begun to execute a serialized portion of the program, any other thread trying to execute this portion must wait until the first thread finishes. Synchronization is used to control access to state both in small scale multiprocessing systems in multithreaded environments and multiprocessor computers and in distributed computers consisting of thousands of units in banking and database systems, in web servers, and so on.

About computerscience term Polling disambiguation Unreferenced auto yes date December 2009 Polling , or polled operation, in computerscience , refers to actively sampling the status of an external device by a client program as a synchronous activity. Polling is most often used in terms of input output nowrap I O , and is also referred to as polled nowrap I O or software driven nowrap I O . Polling is sometimes used synonymously with busy wait polling busy waiting . In this situation, when an nowrap I O operation is required the computer does nothing other than check the status of the nowrap I O device until it is ready, at which point the device is accessed. In other words the computer waits until the device is ready. Polling also refers to the situation where a device is repeatedly checked for readiness, and if it is not the computer returns to a different task. Although not as wasteful of CPU cycles as busy wait, this is generally not as efficient as the alternative to polling, interrupt driven nowrap I O . In a simple single purpose system, even busy wait is perfectly appropriate if no action is possible until the nowrap I O access, but more often than not this was traditionally a consequence of simple hardware or non Computer multitasking multitasking operating systems . Polling is often intimately involved with very low level hardware. For example, polling a parallel printer port to check whether it is ready for another character involves examining as little as one bit of a byte . That bit represents, at the time of reading, whether a single wire in the printer cable is at low or high voltage. The nowrap I O instruction that reads this byte directly transfers the voltage state of eight real world wires to the eight circuits flip flops that make up one byte of a CPU register. Polling has the disadvantage that if there are too many devices to check, the time required ... request Select Unix Kqueue DEFAULTSORT Polling ComputerScience Category Input output Comp ... more details
