SupercomputerA supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). Since 2017, there have existed supercomputers which can perform over 1017 FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (1011) to tens of teraFLOPS (1013).
Discrete-event simulationA discrete-event simulation (DES) models the operation of a system as a (discrete) sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. Between consecutive events, no change in the system is assumed to occur; thus the simulation time can directly jump to the occurrence time of the next event, which is called next-event time progression.
Software deploymentSoftware deployment is all of the activities that make a software system available for use. The general deployment process consists of several interrelated activities with possible transitions between them. These activities can occur on the producer side or on the consumer side or both. Because every software system is unique, the precise processes or procedures within each activity can hardly be defined. Therefore, "deployment" should be interpreted as a general process that has to be customized according to specific requirements or characteristics.
Home computerHome computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability.
UnderemploymentUnderemployment is the underuse of a worker because a job does not use the worker's skills, is part-time, or leaves the worker idle. Examples include holding a part-time job despite desiring full-time work, and overqualification, in which the employee has education, experience, or skills beyond the requirements of the job. Underemployment has been studied from a variety of perspectives, including economics, management, psychology, and sociology. In economics, for example, the term underemployment has three different distinct meanings and applications.
Job guaranteeA job guarantee is an economic policy proposal that aims to provide a sustainable solution to inflation and unemployment. Its aim is to create full employment and price stability by having the state promise to hire unemployed workers as an employer of last resort (ELR). The economic policy stance currently dominant around the world uses unemployment as a policy tool to control inflation. When inflation rises, the government pursues contractionary fiscal or monetary policy, with the aim of creating a buffer stock of unemployed people, reducing wage demands, and ultimately inflation.
