Assignment : Data Storage 

Computer processes need to be able to store data during the execution phase. The data may need to be stored temporarily in volatile memory or permanently in secondary storage. Volatile memory is implemented for random access in RAM (Random Access Memory) and magnetic disks, optical disks, and Flash memory are used to store data permanently. Data is stored on a disk using a file system, which uses file and directory structures.
While high speed processors may enable high performance applications to achieve high throughput, disk data transfer rates, speed, and capacity are also critical for the overall performance of an application because slow RAM and slow disks have an impact on application performance.
Write a three  (3)page paper in which you:

1. Realize business and organizational data storage and fast access times are much more important than they have ever been. Compare and contrast magnetic tapes, magnetic disks, optical discs, Flash RAM, and solid-state drives (SSD) in terms of:
   1. Speed
   2. Volatility
   3. Access methods
   4. Portability
   5. Cost
   6. Capacity
2. Describe a situation in which you would select each of the above media.
3. Describe a situation in which you would use Static RAM (Random Access Memory) (SRAM) and Dynamic RAM (DRAM), and Synchronous DRAM (SDRAM) and emphasize access times, fabrication technology, data transfer rates, and capacity.
4. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

"Exception Error Trapping" Please respond to the following:

• No program will work 100% of the time. It is important for a program to be able to handle various types of unexpected errors. Try-Catch has multiple ways to trap the failures. Write a Visual Basic snippet example to trap an error. Consider: running out of disk space, database failure, and hard drive failures.
• After trapping an error, describe some of the basic factors that need to be considered in order to determine if you would allow the program to continue or stop. (For example, if you ran out of disk space writing out banking transactions, it would make sense to stop the program and display an error message.) Develop two (2) best practices using various situations to stop a program from continuing.
