WGU C952 - Computer Architecture Questions and Answers Already Passed information revolution -✔✔ Computers have led to a third revolution for civilization, with the _________________ taking its... place alongside the agricultural and the industrial revolutions. Personal Computer (PC) -✔✔ A computer designed for use by an individual, usually incorporating a graphics display, a keyboard, and a mouse. Server -✔✔ A computer used for running larger programs for multiple users, often simultaneously, and typically accessed only via a network. Supercomputer -✔✔ A class of computers with the highest performance and cost; they are configured as servers and typically cost tens to hundreds of millions of dollars. Embedded computer -✔✔ A computer inside another device used for running one predetermined application or collection of software. processor cores -✔✔ Many embedded processors are designed using ______________, a version of a processor written in a hardware description language, such as Verilog or VHDL. Personal mobile devices (PMDs) -✔✔ are small wireless devices to connect to the Internet; they rely on batteries for power, and software is installed by downloading apps. Conventional examples are smart phones and tablets. Warehouse Scale Computers (WSCs) -✔✔ Taking over from the conventional server is Cloud Computing, which relies upon giant datacenters that are now known as__________________________ Cloud computing -✔✔ refers to large collections of servers that provide services over the Internet; some providers rent dynamically varying numbers of servers as a utility. Software as a Service (SaaS) -✔✔ delivers software and data as a service over the Internet, usually via a thin program such as a browser that runs on local client devices, instead of binary code that must be installed, and runs wholly on that device. Examples include web search and social networking. Multicore microprocessor: -✔✔ A microprocessor containing multiple processors ("cores") in a single integrated circuit. Terabyte (TB): -✔✔ Originally 1,099,511,627,776 (240) bytes, although communications and secondary storage systems developers started using the term to mean 1,000,000,000,000 (1012) bytes. tebibyte (TiB) -✔✔ To reduce confusion, we now use the term _______________ for 240 bytes, defining terabyte (TB) to mean 1012 bytes. Moore's Law . -✔✔ __________________ states that integrated circuit resources double every 18-24 months abstractions -✔✔ A major productivity technique for hardware and software is to use________________ to characterize the design at different levels of representation; lower-level details are hidden to offer a simpler model at higher levels. common case -✔✔ Making the________________ fast will tend to enhance performance better than optimizing the rare case. parallel -✔✔ Since the dawn of computing, computer architects have offered designs that get more performance by computing operations in _______________. pipelining -✔✔ A particular pattern of parallelism is so prevalent in computer architecture that it merits its own name: _______________ , which moves multiple operations through hardware units that each do a piece of an operation, akin to water flowing through a pipeline. prediction -✔✔ The idea of _________________ is that, in some cases it can be faster on average to guess and start working rather than wait until you know for sure, assuming that the mechanism to recover from a misprediction is not too expensive and your prediction is relatively accurate. hierarchy of memories -✔✔ Architects have found that they can address conflicting demands of fast, large, and cheap memory with a hierarchy of memories, with the fastest, smallest, and most expensive memory per bit at the top of the hierarchy and the slowest, largest, and cheapest per bit at the bottom. dependable -✔✔ Since any physical device can fail, we make systems dependable by including redundant components that can take over when a failure occurs and to help detect failures. Systems software -✔✔ Software that provides services that are commonly useful, including operating systems, compilers, loaders, and assemblers. Operating system -✔✔ Supervising program that manages the resources of a computer for the benefit of the programs that run on that computer. [Show More]
