Mini-Case: Cathy’s Collectibles Mini-Case: Cathy’s Collectibles Husameddin Alnajjar Keller Graduate School of Management. Abstract Your cousin Cathy runs a part-time business out of her apartment. She buys and sells collectibles such as antique prints, baseball cards, and cartoon cells and has recently discovered the Web with its many auction sites. She has begun buying and selling on the Web by bidding on collectibles at lesser-known sites and selling them at a profit at more well-known sites. She downloads and uploads lots of graphics (pictures of the items she’s buying and selling). She is getting frustrated with the slow Internet access she has with her 56-Kbps dial-up modem and asks you for advice. DSL is available at a cost of $60 per month for 1.5 Mbps down and 384 Kbps up. Cable modem service is available for a cost of $50 per month for 1.5 Mbps down and 640 Kbps up. Wireless DSL is available in her apartment building for $45 per month for 1.5 Mbps down and 256 Kbps up. Explain the differences in these services and make a recommendation. Answer DSL has been around a long time, and with ADSL2+ out, speeds are faster than ever. DSL has the following advantages over the competition: Bandwidth - DSL (Digital Subscriber Line) it is a point to point technology that provides high-speed data transmission over traditional telephone lines. With DSL the shorter the distance, the higher the speed, because with a shorter distance, the circuit suffers less attenuation and higher-frequency signals can be used, providing a greater bandwidth for modulation.
