CPU cache. A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have different independent caches, including instruction and data caches, where the data cache is usually organized as a hierarchy of more cache levels (L1, L2, etc.).
USPS Tracking is a way for you to make sure that your most important packages make it to their final destinations. The US Postal Service can tell you the date, time and zip code where your item was delivered, giving you peace of mind.
How long do I have to wait for my USPS tracking to update before you will file a claim? USPS does not consider a package lost or stolen until fifteen (15) days have passed since the last tracking update (excluding Sundays and federal holidays). In the unlikely event your tracking does not update by the fifteenth day, we will be allowed to initiate the claims process. Prior to that, all we can do is notify USPS of the situation. Please contact us if your tracking does not update for fifteen (15) days, so our Claims Department can act accordingly. Last Updated: 1 year ago in After Ordering
