Partitions offer a way to divide the space on a single physical hard disk into multiple areas, each of which is treated as a different disk within Windows. Some people create separate partitions to help organize their files. For example, you might store the Windows system files and application files on one partition, user-created documents on another partition, and backup files on another partition. Another reason to use multiple partitions is to isolate operating systems from one another when you install more than one operating system on a computer. Although it is technically possible to install some operating systems on the same partition, Microsoft does not recommend or support this practice.

A cache of DNS name-to-address resolutions. A cache of DNS address-to-name resolutions (also called the reverse cache). A cache of failures to perform DNS address-to-name resolutions. This cache is also called the negative cache. Its purpose is to mitigate possible DOS attacks on the reverse cache. After a failure to locate an entry in the reverse cache, the negative cache is consulted; if the entry is found there, the firewall will not attempt a reverse DNS query against the Windows DNS resolver.

Windows 7 Editions The Windows 7 operating system comes in multiple editions. You will sometimes see these editions referred to as Stock Keeping Units (SKUs). Microsoft targets specific editions at different usage scenarios, providing cheaper editions to customers who do not want all the features available in a more expensive edition.
