Key characteristics that distinguish primary and secondary storage include cost, capacity, speed,and.volatilityReview Questions1. What similarities exist in mechanical, electrical, and optical methods of computation?All harness the energy of something that’s moving (such as gears, electrons, and photons)to perform work. All are subject to fundamental speed limits based on the speed of theirmoving “parts.” All perform computation by using the mathematical properties ofphysical phenomena.2. What shortcomings of mechanical computation did the introduction of electronic computing devicesaddress?Slow speed, unreliability (because of friction and wear), and fabrication complexity3. What shortcomings of electrical computation will optical computing devices address?.Systems Architecture, 6eCh.
2 Solutions-4Fabrication complexity (lack of wiring) and unreliability caused by heat, friction, andresistance4. What is a CPU? What are its primary components?The CPU is the brain of a computer system. It fetches and executes instructions in astored program and controls the movement of data between computer systemcomponents.
The primary CPU components are the control unit, arithmetic logic unit(ALU), and registers.5. What are registers? What are their functions?Registers are storage locations in the CPU used to hold instructions and data temporarily.6. What is main memory?
How does it differ from registers?Main memory is a collection of storage locations, typically implemented with randomaccess memory (RAM), that holds instructions and some or all of the data of currentlyrunning programs. Primary storage has more capacity than registers but is slower toaccess.7. What are the differences between primary and secondary storage?Primary storage is more volatile, faster, and more expensive than secondary storage.Because of its higher cost, its capacity is usually lower than in secondary storage. Thesedifferences determine differences in use—chiefly, primary storage supports ongoing CPUactivity by storing instructions and data of currently running programs.8. How does a workstation differ from a desktop computer?There might be no difference, but some people consider the term “workstation” to implya more powerful system than a typical desktop computer—one that’s capable of handlinghardware-intensive tasks, such as complex mathematical computation, computer-aideddesign (CAD), and manipulation of high-resolution video images.9. How does a supercomputer differ from a mainframe computer?A supercomputer is optimized for the fastest possible execution of mathematicalcomputations.
A mainframe is optimized for high I/O capacity and supporting theinformation-processing needs of many simultaneous users and running programs.Supercomputers are generally more expensive than mainframes and often use moreadvanced technology, particularly for the CPU and primary storage.10. Describe three types of multicomputer configurations. What are their comparative advantages anddisadvantages?Multicomputer configurations include clusters, blades, and grids. A cluster is a group ofsimilar or identical computers, connected by a high-speed network, that cooperate toprovide services or run a single application.
Clusters are scalable and fault tolerant, butthey’re more complex to configure and administer.A blade is a circuit board containing most of a server—typically one or more CPUs,memory areas, and network interfaces. It lacks secondary storage, external I/Oconnections, and a power supply. Blades are similar to clusters in their scalability(especially for computation-intensive tasks) and their complexity to configure andadminister. They’re less fault tolerant than clusters because multiple blades share a singlelocation, including cabinet, power supply, and sometimes I/O connections. However,blades concentrate more computing power in less space and with lower powerrequirements than a typical cluster needs.A grid is a group of dissimilar computers, connected by a high-speed network, thatcooperate to provide services or run a shared application.
Grids aren’t as scalable asclusters and blades because of their architectural differences and because systems in agrid might be located farther away from each other than systems in a cluster are. They’re.Systems Architecture, 6eCh. 2 Solutions-5also complex to configure and administer. However, they offer the unique capability tocollaborate on tackling large problems when needed and operate independently underlocal control at all other times.11. What classes of computer systems are normally used for servers?Any computer class can be used for a server.
The class depends on the number and typeof resources and the number of simultaneous accesses to these resources.12. What is Grosch’s Law? Does it hold today? Why or why not?Grosch’s Law states that computing power, measured by millions of instructions persecond (MIPS), is proportional to the square of hardware cost; therefore, large andpowerful computers will always be more cost effective than smaller ones. If all classes ofcomputers are considered as a group, however, the law doesn’t hold today.
It doesn’taccount for technological changes since Grosch’s time, such as multiple classes ofcomputers, multicomputer configurations, computer networks, and recent trends, such asvirtualization and cloud computing.13. How can a computer system be tuned to a particular application?Subsystems (for example, CPU, memory, graphics, and secondary storage) can be addedor enhanced to alter a computer’s capabilities. For example, database applications aretypically aided by increasing the computer’s memory and secondary storage capabilities.This increase might be accomplished by doubling installed memory, adding secondarystorage devices, and upgrading the secondary storage controller.14. What characteristics differentiate application software from system software?Application software is special purpose—written to address specific needs of specificusers. System software is general purpose—it provides support functions for many typesof application processing tasks. System software also interacts directly with hardware,and application software does not.15. In what ways does system software make developing application software easier?System software provides general-purpose reusable functions that can be incorporatedinto application software.
Many of the functions implement specific hardware control andinterface requirements. Therefore, application programmers don’t need to write thesefunctions themselves, and they need little or no knowledge of the underlying hardware.16. Why has the development of system software paralleled the development of computer hardware?Software consumes hardware resources and uses them to provide IS services to users.Software can’t provide services that require nonexistent or prohibitively expensivehardware resources. Therefore, software advances follow the arrival of powerful andinexpensive hardware.17. List at least five types of resources that computers on a local area network or wide area network canshare.Program (software) files, I/O devices, text files, sound and video files, databases, WebpagesResearch ProblemsProject 1The instructor might want to make this exercise more challenging by imposing budgets for each user type –say $500 for the home user and accountant and $750 or $1000 for the architect.
Software selection may ormay not be incorporated. If it is, OS selection is an issue for the accountant and architect.Systems Architecture, 6eCh.
2 Solutions-61. Home user: This system tends to emphasize graphics performance at the expense of other components.However, the budget is more than adequate for the purpose, although it can be consumed quickly byperipherals (such as a high-quality inkjet printer and scanner) and software.2.
Accountant: The system features to focus on include faster memory, a high-powered CPU, and anetwork card. An upgraded OS might also be considered.3.
Architect: A large monitor or a dual-monitor setup is a must in this situation, but fitting it in the budgetwill be tough. The applications also demand large amounts of fast primary storage, secondary storage,and a high-powered CPU.

An upgraded OS might also be considered.Project 2Students might not have absorbed enough technical information to do this project, but shopping forcomputers by taking the sales hype as truth is a useful exercise in discovering the costs and capabilities ofcurrent server and minicomputer systems.Project 3Many supercomputers are clusters of hundreds or thousands of high-end midrange computers.
. 3.1k DownloadsPart of thebook series (POWSYS) AbstractPhotovoltaics (PV) is a renewable technology with the highest theoretical potential. World-wide 5.86 GWp were installed in 2006. Thereof 2,860 MWp are in Germany; 1,709 MWp in Japan and 624 MWp in the United States. These three countries have installed over 89% of the total world PV power. The index p of the power means peak values for a standardized installation of 1,000 W/m2 and a temperature of 25°C. Most of the PV plants work grid connected because of increased tariffs for energy feed-in.
Because of their similar output behavior, Fuel Cell (FC) systems are also discussed here. They generate DC output power like PV generators, which must be converted into AC with power electronic converters. FC are usable in different power system applications and for automotive and other mobile technologies.
An important advantage is the lack of dangerous emissions. In 2006, 85 MW electrical power from FC was global installed, with 40.8 MW in the United States, 17.1 MW in the European Union (mostly Germany) and 9.9 MW in Japan.
