...Project Management Question I: (Discussion and Review Questions No.6) What is a work breakdown structure, and how is it useful for project planning? Work breakdown structure (WBS) – a hierarchical listing of what must be done during a project. It is useful due to the fact that large projects usually involve a very large number of activities, planners need some way to determine exactly what will need to be done so that they can realistically estimate how long it will take to complete the various elements of the project and how much it will cost. Question II: What kind of projects need project management? What are the five phases of project management? To your understanding, what is the key reason why many projects fail? Anything with a goal and/or expected outcome, regardless if it has a budget or not, can benefit from using project management principles. The five phases of project management: 1. Scoping the project 2. Developing the plan 3. Launching the plan 4. Monitoring & controlling 5. Closing out the project Poor requirements analysis causes many of these failures, meaning projects are doomed right from the start. Question III: Chris received new word processing software for her birthday. She also received a check, with which she intends to purchase a new computer. Chris’s college instructor assigned a paper due next week. Chris decided that she will prepare the paper on the new computer. She made a list of the activities she will need...

...development skills, you also need to understand the server side of the Web— in particular, how server-side scripting fits into Web development. In this chapter, you will study server-side scripting with ASP.NET. But before getting into server-side scripting, it’s helpful to set the stage by reviewing the fundamentals of client/server architecture. 507 508 Chapter 11 ASP.NET CLIENT/SERVER ARCHITECTURE There are many definitions of the term’s client and server. In traditional client/server architecture, the server is usually some sort of database from which a client requests information. A server fulfills a request for information by managing the request or serving the requested information to the client—hence the term, client/server. A system consisting of a client and a server is known as a two-tier system. One of the primary roles of the client, or front end, in a two-tier system is the presentation of an interface to the user.The user interface gathers information from the user, submits it to a server, or back end, then receives, formats, and presents the results returned from the server. The main responsibility of a server is usually data storage and management. Heavy processing, such as calculations, on client/server systems usually takes place on the server. As desktop computers become increasingly powerful, however, many client/server systems place at least some of the processing...

...stock and hatching, rearing parent stock, production of hatching eggs, hatching day old chick of broilers, growing broilers, slaughtering of broilers and further processing and selling poultry meat through supermarkets, supply to restaurants or further processing into convenience products. Only small numbers of organizations are Breeding Companies. For the most of the companies this business starts with growing a day old broilers. One section of the business is Broiler farm. The optimum for the initial operation of the business would be 10,000 chickens. The one day old chickens hatched from the parent generation are delivered to the farm. The Broiler farm will be on area of about 10,000 sq. meters for the farm with road connections, water availability and houses for growing broilers. Broiler farms, where day old chicks are raised to slaughter weight, will be located near the processing facilities to minimize the transport costs. The basic needs for the broilers are fresh feed, fresh water, fresh air, light, darkness, thermal environment, protection and space. Second section of the business is feed mill for food production. This section will provide meals that give good result for broilers with best conversion. Third section of the business is slaughterhouse and further processing of poultry meat. The processing section will selectively collect chickens of varying sizes from the broiler farm depending on its needs. The business objective is...

...additional processing capabilities can increase employee productivity, expand business opportunities, and allow for more flexibility. - To assemble an effective and efficient system, you should select and organize components while understanding the trade-offs between overall system performance and cost, control, and complexity. ex) Racecar : power delivery(effective and efficiency), how much(cost), how reliable(control), how many engine(complexity) hardware components - computer system hardware components include devices that perform input, processing, date, and output. - Central processing unit (CPU) consists of three associated elements : the arithmetic/logic unit, the control unit, and the register areas. - Primary storage, also called main memory or memory, is closely associated with the CPU. Memory holds program instructions and data immediately before or after the registers. Hardwar components in Action : instruction and execution Instruction time : Step 1) fetch instruction, step 2) decode instruction Execution time : step 3) execute instruction, step 4) store result Completing the instruction phase followed by the execution phase is called a machine cycle. Some processing units can speed processing by using pipelining, whereby the processing unit gets one instruction, decodes another, and executes a third at the same time.

...assigned to I/O devices, and reads and writes to those addresses are interpreted as commands to the I/O device 2. [10 points] Why is DMA an improvement over CPU programmed I/O? When CPU programmed I/O is used the CPU is usually fully occupied for the entire duration of the read or write operation and is unavailable to perform other work. With DMA the CPU initiates the transfer, does other operations while the transfer is in progress, and receives an interrupt form the DMA controller when the operation is complete. This frees up the CPU for other tasks. 3. [10 points] When would DMA transfer be a poor choice? When the amount of data transferred between memory and the I\O device is small. In this case the work to set it up would be more than the benefits of having it. 4. [15 points] Mention two advantages and disadvantages for using a single bus as a shared communication link between memory, processor and I/O devices. Advantages: versatility and low cost Disadvantages: communication bottleneck 5. [15 points] What is the average time to read or write a 512-byte sector for a typical disk rotating at 7200 RPM? The advertised average seek time is 8ms, the transfer rate is 20MB/sec, and the controller overhead is 2ms. Assume that the disk is idle so that there is no waiting time. -8 + (.5*60*1000/7200) + (512/20*2^20) * 1000 + 2 = -14.17 ms 6.

...reporting on servers/disks not used by transaction processing systems most firms want to set up transaction processing systems so there is a high probability that transactions will be completed in what is judged to be an acceptable amount of time. Reports and queries, which can require a much greater range of limited server/disk resources than transaction processing, run on the servers/disks used by transaction processing systems can lower the probability that transactions complete in an acceptable amount of time. Or, running queries and reports, with their variable resource requirements, on the servers/disks used by transaction processing systems can make it quite complex to manage servers/disks so there is a high enough probability that acceptable response time can be achieved. Firms therefore may find that the least expensive and/or most organizationally expeditious way to obtain high probability of acceptable transaction processing response time is to implement a data warehousing architecture that uses separate servers/disks for some querying and reporting. To use data models and/or server technologies that speed up querying and reporting and that are not appropriate for transaction processing There are ways of modeling data that usually speed up querying and reporting (e.g., a star schema) and may not be appropriate for transaction processing because the modeling technique will slow down and complicate transaction processing. Also, there are server technologies that that...

...system-level requirements and refine them into a detailed blueprint for the program. Up to this point, you have identified the processes the program must perform, but you have not given any consideration to exactly how the processes work together to solve the problem. At this point, you must generate a description of the processing using pseudocode, a natural language description of the processing the application must perform. The natural place to start is the system-level requirements you identified in the input-process-output (IPO) chart. Determine how the processes work together: Once you have determined the top-level logic, you can design each individual process. This step-wise refinement process allows you to conceptualize a vague problem into increasing levels of details to actually generate a working program. This point is important because the step-wise refinement process is used throughout the entire program development—each new piece of information is based on, and is a refinement of, the information uncovered in the previous step. For this week’s CheckPoint, you will refine the IPO table into a complete design, as demonstrated on pp. 80 & 83 in Ch. 2 of Prelude to Programming. Additionally, refer also to the Input and Output Process Example in Appendix B to see how more detailed analysis and design relates to the previously constructed IPO chart. The following information demonstrates all the items you need to develop your programming assignments and the final project...
