How are server computers made more reliable than desktop machines?
Server computers are just slimmed down desktop alot of times. They don't have the fast graphics cards, etc. that a desktop has. They typically have a large amount of system memory, a large harddrive, and a multitasking cpu. The real important thing about most servers which makes them reliable is the fact that many of them operate on what is called RAID. They have multiple harddrives in the system that hold multiple copies of the same data. If one drive fails the other one can pick up where the old one left off and the system isn't compromised. You can do the same thing with your standard desktop, but most people don't want to spend the money on the extra drives required for this.
What are the functional views of the computer?
Data movement, apparatus control, and data processing are the three main functional views of the computer. Also, mechanism data is another functional view of the computer.
Can one create multiple partitions on a Western Digital My Passport Elite or Essential Drive?
Yes. My passport drives are formatted in FAT32 format from factory. You'll first need to format the entire drive to NTSF format in order to create multiple partitions.
Note: the instructions below will only work with Windows Vista. If you're using XP, then you'll need something like Partiton Magic or similar.
1st. Backup all your data in your current partition. Keep it in a safe place. I would recommend putting all your files in your PC.
2nd. Format the drive in NTSF format. From My Computer screen, right-click on My Passport drive. Select "Format". Once the Format window pops up, keep all default settings and make sure NTFS is selected. Also select "Quick Format" checkbox. Note: not checking Quick Format will cause the formatting process to take up to 2 hours depending on the size of your drive.
3rd. Now that your drive is formatted in NTSF format. Right-click My Computer icon from the Desktop or Start Menu and select "Manage". The Computer Management window will appear. Under "Storage" select "Disk Management"
