(25 pts) Define the following terms using 1-3 sentences or a formula (5 pts each):  \n(a) Moore’s Law  \nMoore's law is the observation that, over the history of computing hardware , the number oftransistors on integrated circuits doubles approximately every two years. The period often quoted as \"18 months\" is due to Intel executive David House, who predicted that period for a doubling in chip performance (being a combination of the effect of more transistors and their being faster) .  \n[Source: [http://en.wikipedia.org/wiki/Moore](http://en.wikipedia.org/wiki/Moore)'s law]  \n(b) Datapath  \nPart of a computer that does the work of arithmetic and logic calculations and performs other instructions including but not limited to I/O and branching.  \n(c) Benchmark  \nIn computing, a benchmark is the act of running a computer program , a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. The term 'benchmark' is also mostly utilized for the purposes of elaborately-designed benchmarking programs themselves. [Source: [http://en.wikipedia.org/wiki/Benchmark_](http://en.wikipedia.org/wiki/Benchmark_)(computing) ]  \n(d) Von Neumann Bottleneck  \nThe meaning of the term [“von Neumann architecture”] has evolved to mean a storedprogram computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.  \n[Source: [http://en.wikipedia.org/wiki/Von_Neumann_architecture](http://en.wikipedia.org/wiki/Von_Neumann_architecture) ]  \n(e) Register (in a CPU chip)  \nIn computer architecture , a processor register is a small amount of storage available as part of a CPU or other digital processor. Such registers are (typically) addressed by mechanisms other than main memory and can be accessed more quickly.  \n[Source: [http://en.wikipedia.org/wiki/Processor_register](http://en.wikipedia.org/wiki/Processor_register)]  \nPRINT YOUR NAME:   KEY  CDA3101 NUMBER:    \nQ2.
