The basic Computer Organization tells us how exactly all the units in the system are arranged and interconnected. components of performance and how each is measured are: Average System Bus and Interconnection, PCI, Computer Function, I-Cycle, Interrupt and Class of Interrupts, Von-Neumann M/c: Structure of IAS. Lets understand what performance means in cache memory, how it is measured and its formula. PerformanceAssessment In evaluating processor hardware and setting requirements for new systems, performance is one of the key parameters to consider, along with cost, size, security, reliability, and, in some cases power consumption. In other words, in terms of value in dollars, pounds, euros, etc.We can see how good a firm’s financial performance is by looking at its return on assets and return on investment. With respect to execution time of a program on a processor X, we say that Source: Flickr.
