Technical requirements

Technical requirements are a set of specific requirements that must be met in order for a product or system to function correctly. They are usually documented in a technical specification or product manual and may include requirements for materials, components, software, interfaces, and performance. Technical requirements are often confused with functional requirements, which define what … Read more

De facto standard

A de facto standard is a standard that has been adopted as a standard by convention, rather than by an explicit standardization process. De facto standards arise when a specifications document is created by a single company or organization, which is then adopted by others. What is an example of de facto standard? A de … Read more

Greedy algorithm

A greedy algorithm is an algorithmic technique that makes the most optimal choice at each step in order to maximize the overall benefit. In other words, a greedy algorithm always chooses the option that looks the best at the current moment, without considering the long-term impact of its decisions. One common example of a greedy … Read more


Heuristic (adjective): relating to or based on experience or trial and error. In computing, a heuristic is an approach to problem solving that employs a simplified, trial-and-error method in order to find a solution that is fast and effective, but not necessarily optimal. Heuristics are typically used when an exact, step-by-step method is not feasible … Read more


“Time” refers to the elapsed time between two events. It is typically measured in seconds, minutes, hours, or days. Elapsed time is the time that has passed since the start of an event, or the time that remains until the end of an event. How did the concept of time originate? There is no definitive … Read more

Dark energy (quintessence)

Dark energy is the name given to the hypothetical form of energy that would be responsible for the observed accelerated expansion of the Universe. It is thought to make up around 68% of the total energy in the Universe, with the remainder being made up of dark matter (27%) and ordinary matter (5%). The nature … Read more

Runtime system

A runtime system is a software system that is responsible for executing a computer program. It provides the necessary environment for running the program, such as memory management, security, and input/output (I/O) services. The term “runtime system” is often used interchangeably with “virtual machine” or “execution environment”. What is a run time engine? A run … Read more


The term parallel refers to two or more things that are occurring at the same time. In computing, parallelism is the ability of a computer to run two or more programs at the same time. This can be accomplished by running multiple processors at the same time, or by running a single processor that is … Read more

State machine

A state machine is a mathematical model of computation. It is an abstract machine that can be in one of a finite number of states. The machine is in only one state at a time; it can change from one state to another when initiated by a triggering event or condition, which is called a … Read more
