ahh i got it .. i didnt look at 1000 PER YEAR for 5 years

therefore since its 100,000 pages, for 5 years it's 500,000 pages.
since you are given the cost in per 100 pages, you have to multiply each one by 5000 and add the cost of the printer

you get :

A: 26,159
B: 18,299
C: 20,499
C: 6,495

(v.) (1) To prepare a storage medium, usually a disk, for reading and writing. When you format a disk, the operating system erases all bookkeeping information on the disk, tests the disk to make sure all sectors are reliable, marks bad sectors (that is, those that are scratched), and creates internal address tables that it later uses to locate information. You must format a disk before you can use it.
Note that reformatting a disk does not erase the data on the disk, only the address tables. Do not panic, therefore, if you accidentally reformat a disk that has useful data. A computer specialist should be able to recover most, if not all, of the information on the disk. You can also buy programs that enable you to recover a disk yourself.

The previous discussion, however, applies only to high-level formats, the type of formats that most users execute. In addition, hard disks have a low-level format, which sets certain properties of the disk such as the interleave factor. The low-level format also determines what type of disk controller can access the disk (e.g., RLL or MFM).

Almost all hard disks that you purchase have already had a low-level format. It is not necessary, therefore, to perform a low-level format yourself unless you want to change the interleave factor or make the disk accessible by a different type of disk controller. Performing a low-level format erases all data on the disk.


cant help u on the evaluation matrix

Nice explanation, but although the manufacturer has had a low level format on the HDD, i still like to format it into the according File System.

personally NTFS

more so a NTFS, it's more better i find it, and with the new Windows OS due to release in 2005/2006, i'm looking forward to the new File System which works with NTFS to bring a even better performance for the OS.

An evaluation is an evaluation.
A matrix is a 2-dimensional array or a "table". i.e.

Depends on what "section" of the h/disk the OS has been installed in. But if you havent installed other programs yet (after installing OS) i'd say theres a good chance of geting most of your porn back. :D
