Question #31: Try to count how many personal computers are at your home, in the PC lab. Applying Concepts 31: Analyze each of the business scenarios outlined below. Recommend a hardware configuration for each of the scenarios listed using the table. Develop a rationale for your configuration selections. Assume that the cost of the hardware configurations will be approved based on your rationale. Computer Configuration: C D A B Features: Processor (Speed/clock rate) Internal Storage (RAM/GB) Internal storage (hard disk) Monitor size/resolution Video Graphics (memory/resolution) Printer type (PPM/DPI) Software through a browser as well as downloadable software An artist creates complex graphics. The software required to develop these graphics requires large and complex programs. While the quantity of their graphic printouts is not substantial, they must be of high quality. (CD-R: write once, read many, and flash memory USB drives) B. The administrative personnel use a computer for editing and printing documents and small reports using word-processing software. These documents will require a professional and quality appearance. The employees will maintain the document files on their computer system. C. The data analysts require access to corporate databases to complete complex statistical analysis. These queries and data analysis can require significant time to complete the mathematical calculations. The analysts will print reports from the backup medium. 142 Information Technology
