Chapter 10, page 489 - 490. Choose 5 terms to describe in detail.

The five terms I have choosen are:

Array: A group of hard drives using RAID is called an array. RAID stands for Redundant Array of *Inexpensive Disks (*or Independent Disks)
--> picture of "LaCie Biggest S2S 5TB RAID array"

CDFS stands for Compact Disk File System. It is a 32 bit program that runs in protected mode (other applications can't access this memory). It also uses the VCACHE driver which gives smoother playback. VCACHE is a 32 bit driver, that can change the size of the disk cache depending on available disk space and application needs.

Drop Height, is the height the manufacture states that you can "safely" drop a removable hard drive without losing data, say if it falls off the desk.

Fault Tolerance "is a computer's ability to respond to a fault or catastrophe, such as a hardware failure or power outage, so that data is not lost." You can, and should, also protect your data by backing it up either to a second hard drive installed on your computer, an external hard drive, tape drives, flash drives or by using an online back up company.

SIMD stands for "single instruction, multiple data." It is programmed into the CPU so that the CPU can perform the same action (i.e. retrieve, calculate, or store) at the same time on two or more pieces of data instead of calling the same instruction each time. It was developed with better multimedia applications in mind.

Chapter 8 Hands On Project

I am late, and I know it.

I needed to use the Internet to research floppy drives.
I went to Tiger Direct:

What is the price of an internal floppy drive? The price ranged from $14.99 to $29.98

What kind of connection do external floppy disk drives use? They use an IDE cable.

What is the price of an external drive? Both models were offered at $19.99

Why do you think external drives cost more than internal drives? I don't think they do anymore. While the one internal was less expensive, the other three cost either the same or more.

What are the advantages of external drives? The advantage would be portability. You can connect to your desktop and move it to your laptop. Or take it to work and back. If you are an IT tech, you can use it on newer computers that don't have a floppy drive installed to run the set up or restore disk.

Internal drives? OK, on a modern home computer, almost none. On a business computer you may want one to run some back up disks and also store small files like Word files or Excel workbooks.
