Coefficient of Performance - COP - is the ratio between useful energy acquired and energy applied and can be expressed as COP = Eu / Ea (2) Where COP = coefficient of performance Eu = useful energy acquired (btu in imperial units) Ea = energy applied (btu in imperial units) COP can be used to define either cooling efficiencies or heating efficiencies as for heat pumps. • Cooling - COP is defined as the ratio of heat removal to energy input to the compressor • Heating - COP is defined

The Central Processing Unit Microprocessors‚ also called central processing units (CPUs)‚ are frequently described as the "brains" of a computer‚ because they act as the central control for the processing of data in personal computers (PCs) and other computers. Chipsets perform logic functions in computers based on Intel processors. Motherboards combine Intel microprocessors and chipsets to form the basic subsystem of a PC. Because it’s part of every one of your computer’s functions‚ it

* Cognitive Jean Piaget was a biologist when he started but by the time he was 21 moved to the development of children’s understanding‚ through observing them whilst he set them tasks. He has given us a better idea of how a child’s mind works and how they grow up. Cognitive theory is concerned with the development of a person’s thought processes. It also looks at how these thought processes influence how we understand and interact with the world. When a child is born it goes through various

Axia College Material Appendix H Memory Powerful central processing units (CPUs) demand large amounts of data‚ and they need that data fast. Otherwise‚ CPU performance is hindered by the lack of data storage support; therefore‚ computers have been designed to supply data through tiering memory and caches‚ which use the hard drive in combination with random access memory (RAM) to deliver massive amounts of data to the CPU. The speed of the RAM is crucial to the performance of data delivery;
