Data Access Protocols I would like to first study the capabilities of a Windows® server. Currently, our 15 computers are connected directly to the internet, these computers pose 15 separate security risks. In addition, these computers have external hard drives that contain all the relative data for our station reports. Which is poorly guarded from malicious attacks. Through a server we can securely control access to the data storage from malicious attempts in 1 location versus 15. Secondly, I

viruses of many different kinds and severely slow down. However, by taking the right steps, someone can improve the performance of there system. To start with, the user can defrag there system which basically means cleaning out the hard drive. The user analyzes the hard drives programs that could be causing errors or bugs and deletes them so that the system can performe at its greatest potential. Also, the user can check his system for hardware and software compatibility. If the user finds a compatibility

include EIDE/PATA, SATA, and SCSI. Until recently, most motherboards included two or more EIDE/PATA host adapters for PATA devices such as hard disks, CD or DVD drives, tape backups, and removable-media drives. Most current systems now have only one EIDE/PATA host adapter, as the industry is transitioning away from EIDE/PATA to SATA inter- faces for both hard disk and DVD drives. Most recent

failure of the Kittyhawk program? e. Is there any way HP could have avoided its fate by addressing these root causes? In June 1992, Hewlett-Packard (referred to HP hereafter) introduced smallest hard disk drive in the world named as the Kittyhawk. It was the first ever commercially produced hard drive in a 1.3 inch form factor. The idea was conceptualized in early 1991 by HP’s management when it was eagerly trying to explore strategies for transforming their Disk Memory Division (DMD) as a
