The stuff on here
|Those darn Jewel Cases|
jewel cases cluttering up my computer center, I have them stacked and
piled all over the place. Problem is some of them are either do
not come with a label on the side or came in an envelope with no jacket
label. There are a number of solutions.
If you have the slim line CD Cases, I doubt there will be any kind of label for the case. If you find one, let me know.
|Leave the PC On or Off|
|Well, here is the greatest of questions. Some
people say leave them on, some say turn them off... you know,
there are all kinds of things that make this one tough to answer
Well, there is no clear cut winner here. If you plan to use your computer often in a day, leave it on. Be careful when you are connected to the internet (see stuff101). If you are a once a week on the computer kind of person (ya freak) then power it down and save on the electric bill.
Me? Pretty much what I do is turn my computers off for the
night, and when I know I will not be using them for a long time.
Course I also used to think daytime running lights were dumb and now I
turn on my lights when I drive... so what do I know (now at least)

Normal compact disc players use an infra-red laser to read the information stored on the disc. DVD players use red lasers, which allows the bits to be packed closer together. DVD also has a more efficient encoding, which helps to increase the capacity of the disc. By using red laser and "squashing" the other parameters it is possible to get 4.7G on a disc.
Another new feature of DVD is the ability to have two layers on each side of the disc. By changing the focus of the laser, it is possible to read data from either the bottom reflective layer, or the upper semi-transparent layer. This almost doubles the capacity of each side of the DVD to 8.5G.
Why do I keep mentioning "per side"? Well, DVD discs can be double sided. This is achieved by making two 0.6mm single sided discs and bonding them together. This means that all DVD discs have to have their reflective layers at a depth of 0.6mm, even if the disc is only a single sided disc.
All this gives a total maximum capacity of 17G on a single DVD disc, which is enough for about 8 hours of video.
One of the applications that DVD is being used for is DVD Video. DVD video stores Mpeg-2 compressed video (at full studio resolution - 4 times the resolution of Video CD) and 5.1 channel surround sound audio (left, center, right, surround right, surround left, subwoofer) encoded either using Dolby AC-3 or Mpeg audio compression.
