Windows 2000 Active Directory replaced Windows NT 4.0 Security Account Manager Database, providing not only increased functionality and scalability, but also enhanced security through more-granular levels of permissions, sophisticated encryption, and two-way, resilient authentication protocol (with Kerberos). With the Windows 2003 platform, Microsoft takes full advantage of these features by allowing more flexibility in the way Active Directory information is partitioned and replicated.
Starting with Windows 2000, Active Directory has been divided into three "logical" partitions (physically residing in the NTDS.DIT file on each domain controller) -- domain, configuration, and schema. The domain partitions store information specific to each domain (accessible primarily via Active Directory users and computers) and shared among all domain controllers in the same domain (partially replicated to all Global Catalogs in the forest).
The configuration partition contains forest-wide information (accessible primarily via Active Directory sites and services) and is shared among all domain controllers in the forest. The schema partition consists of definitions of all objects and their properties that can exist in the other two partitions; it is also shared forest-wide.
This mechanism for partitioning Active Directory data has been extended in Windows 2003 domains by the introduction of the application partition. Several features differentiate it from its three older cou...
(RCS), which will make it more difficult for enemy radar to detect. The UCLASS competition is aimed at developing an aircraft fit for the suppression of enemy air defense (SEAD) mission. This will allow the aircraft to enter enemy airspace and attack SAMs with little chance of being detected. (Harrington, 2010) The S-300, also known as the SA-20 in NATO terms, is one of the most potent surface-to-air missiles and is seen in many advanced countries such as China, North Korea, and Syria with the most

Named after the Nobel laureate in economics, it was stated by him thus: "You can see the computer age everywhere these days, except in the productivity statistics".

Wal-Mart is coming off a disappointing third quarter when its largest revenue generator, sales from U.S. stores, dropped 0.3%. The company also has forecasted flat earnings during the critically important holiday season. While lowering its full-year forecast, Wal-Mart still expects to see modest sales growth in FY2015 through the opening of smaller, more targeted stores, and its longtime strategy of lowering prices. However, there is some doubt whether these measures will be enough to stave off Wal-Mart
TRANSMISSION Th℮ transmission is a d℮vic℮ that is conn℮ct℮d to th℮ back of th℮ ℮ngin℮. It transmits mechanical power from the engine to the drive wheels. The transmission is used to reduce the revolutions of the crankshaft down to a reasonable value by using interlocking gears to reduce the numb℮r of r℮volutions. By doing so, it mak℮s mor℮ ℮ff℮ctiv℮ usag℮ of th℮ ℮ngin℮'s torqu℮ and h℮lps to k℮℮p th℮ ℮ngin℮ op℮rating at an appropriat℮ sp℮℮d. A transmission or gearbox provides speed and torque conversions
