Question
Chapter A, Problem P1AYK
To determine
Compare the prices, suitability and storage capacity of a laptop with predetermined specifications and its further customized upgrade done on the dell website www.dell.com.
Expert Solution & Answer
Explanation of Solution
Given:
Dell is considered as the fastest manufacturing company on earth and specializes in computer customization. Connect to Dell’s website www.dell.com and visit the portion that allows you to customize either a laptop or desktop. Choose an already prepared system and compare its CPU speed, RAM size, monitor quality and storage capacity with the customized version of it based on same parameters.
The system under investigation is XPS 1500 touch.
The configurations of the system are listed below.
| Standard | Customized | |
|---|---|---|
| Name | Dell, XPS 15 Touch | Dell, XPS 15 Touch |
| Cost | $1899 | $2159 |
| RAM | 16 GB | 16 GB (cannot be customized) |
| Hard Drive | 256GB(included in price) | 512GB ($200) |
| Operating System | Windows 10 Home, x64 | Windows 10 Pro, x64 ($60) |
The only hardware modification that can be done in the system is in its storage capacity. The customized system is the one that is more preferred by me. As, it comes with the 16GB internal RAM and the extra storage capacity of 256GB with an increased cost of $200. Also, the operative system is upgraded from the standard Windows 10 home to Windows 10 Pro. It is also recommended from the company’s website.
Conclusion:
Customization capability provided by dell on its products is extremely useful from consumer perspective. A single product model can satisfy the needs of large number of customers who have varying requirements in terms of RAM, CPU speed and storage capacity.
