WAIT STATE Meaning and
Definition
-
Wait state is a term used in computing and refers to a condition where the central processing unit (CPU) is temporarily idle or delayed while waiting for a peripheral device or another component to complete an operation. During this state, the CPU suspends its execution and remains idle until the required input or output (I/O) operation is finished.
In a computer system, the CPU interacts with various peripherals such as memory, hard drives, network cards, or graphic cards in order to perform tasks. Sometimes, due to the speed difference between the CPU and the peripherals, the CPU must wait for data to be transferred, processed, or delivered before it can continue executing instructions.
When a wait state occurs, the CPU may enter a low-power mode to conserve energy while it waits, or it may execute other parallel or unrelated tasks to take advantage of the downtime. The duration of a wait state can vary depending on factors such as the speed of the peripheral device, the complexity of the operation, or any bottlenecks in the system.
Wait states can be detrimental to a computer's overall performance, as they introduce delays and decrease processing efficiency. Minimizing wait states is often a goal in computer design, achieved through techniques such as cache memory, pipelining, parallel processing, and optimization algorithms to reduce the time the CPU spends idle or waiting for external operations to complete.

Etymology of WAIT STATE
The term "wait state" originates from the field of computer programming and computer architecture. It specifically refers to a state in which a microprocessor, or central processing unit (CPU), temporarily pauses or "waits" for a certain event or condition to occur before it can continue executing instructions.
The word "wait" comes from Old English "wætan", meaning "to watch" or "to observe". It has been used in English since the 12th century.
In the context of computer architecture, the concept of a "wait state" was established as computer technology evolved and processors became faster than the memory they were working with. To balance this speed discrepancy, certain wait cycles were introduced to allow memory systems or input/output devices to catch up with the processor's speed.
The term "wait state" itself is a compound noun that combines "wait" and "state".
