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.
The credit score is based on information about your credit card, loan, and other debt accounts listed in your credit report. Things like the account balance, payment history, credit limit, and age of the account are listed on your credit report and used to calculate your credit score. Each factor is given a different weight in calculating your credit score: 1  Payment history counts 35% of your score. 2  Level of debt counts 30% of your score. 3  Length of credit history is 15% of your score. 4  Inquiries and mix of credit are 10% each.
