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.
And itâs not like you can know with absolute certainty what is affecting your credit score. FICO says 35% of your score derives from your payment history and 30% from the amount you owe. But in actually calculating the score, each of these categories is broken down even further, and FICO doesnât disclose how that works.
