The key difference between DVD and Blu-ray/HD-DVD is that DVD is a standard definition format in which the disc information is encoded in 480i (720 x 480 pixels) resolution, and Blu-ray/HD-DVD disc information can be encoded in up to 1080p (1920 x 1080 pixels).
Understanding Credit Scores. Your credit score is a three-digit number that represents the state of your credit. If you know your score, you can get a sense of how lenders, insurance agencies, and interested employers view your credit: Excellent Credit: Credit Score Above 800. If your credit score is above 800, you have an exceptionally long credit history that is unmarred by things such as late payments, collections accounts, liens, judgments, or bankruptcies.
Keep in mind this part of the good credit score makes up 35% of the decision. The next part of the equation is to determine the balances that you may owe on loans or credit cards. If you have a credit card with a $1,000 balance, but owe $950, this does not help you to have a good credit score numbers. Your actual balance in this example would be 95% of your available credit; try to keep it below 50% for each of your credit accounts.
