What is the difference between a single-master and a multi-master domain replication model?
Multi-master replication is a replication model in which any domain controller accepts and replicates directory changes to any other domain controller. Because multiple domain controllers are employed, replication continues, even if any single domain controller stops working.Single-master replication is a replication model in which one domain controller accepts and replicates directory changes to any other domain controller. This master domain controller is known as "Operation Master".Multi-master replication is a method of database replication which allows data to be stored by a group of computers, and updated by any member of the group.The multi-master replication system is responsible for propagating the data modifications made by each member to the rest of the group, and resolving any conflicts that might arise between concurrent changes made by different members.Multi-master replication can be contrasted with master-slave replication, in which a single member of the group is designated as the "master" for a given piece of data and is the only node allowed to modify that data item. Other members wishing to modify the data item must first contact the master node. Allowing only a single master makes it easier to achieve consistency among the members of the group, but is less flexible than multi-master replicationFlexible Single Master of Operation or just single master operation or operations master, is a feature of Microsoft's Active Directory (AD).FSMOs are specialized domain controller tasks, used where standard data transfer and update methods are inadequate. AD normally relies on multiple peer DCs, each with a copy of the AD database, being synchronized by multi-master replication. The tasks which are not suited to multi-master replication, and are viable only with a single-master database, are the FSMOs.Once per domain they only replicate to allThe Relative ID Master allocates security RIDs to DCs to assign to new AD security principals (users, groups or computer objects). It also manages objects moving between domains.The Infrastructure Master maintains security identifiers, GUIDs, and DN for objects referenced across domains. Most commonly it updates user and group links.This is another domain-specific role and its purpose is to ensure that cross-domain object references are correctly handled. For example, if you add a user from one domain to a security group from a different domain, the Infrastructure Master makes sure this is done properly. As you can guess however, if your Active Directory deployment has only a single domain, then the Infrastructure Master role does no work at all, and even in a multi-domain environment it is rarely used except when complex user administration tasks are performed. Because of this, the hardware requirements for machines holding this role are relatively small.The PDC Emulator operations master role processes all password changes in the domain. Failed authentication attempts due to a bad password at other domain controllers are forwarded to the PDC Emulator before rejection. This ensures that a user can immediately login following a password change from any domain controller, without having to wait several minutes for the change to be replicated. The PDC Emulator Operations Master role must be carefully sited in a location to best handle all password reset and failed-authentication forwarding traffic for the domain. The PDC emulator role holder retains the following functions:1.Password changes performed by other DCs in the domain are replicated preferentially to the PDC emulator.2.Authentication failures that occur at a given DC in a domain because of an incorrect password are forwarded to the PDC emulator before a bad password failure message is reported to the user.3.Account lockout is processed on the PDC emulator.4.backward compatibility,The PDC emulator performs all of the functionality that a Microsoft Windows NT 4.0 Server-based PDC or earlier PDC performs for Windows NT 4.0-based or earlier clients.Once per forestThe Schema Master maintains all modifications to the schema of the forest. The schema determines the types of objects permitted in the forest and the attributes of those objects.The Domain Naming Master tracks the names of all domains in the forest and is required to add new domains to the forest or delete existing domains from the forest. It is also responsible for group membership.
What is the difference between Remote Terminal Unit and Programmable Logic Controllers?
Generally speaking -- PLC's are meant to be reprogrammed, possibly with fairly high level languages, RTU's are meant to be changed out when there's a problem (but may also be reprogrammable). RTU's are environmentally rugged. PLC's are more electrically/industrially rugged. Both are controllers. Both are meant to do something without required direct supervision. Both usually have CPU's, although I'm sure there is nothing stopping you from having an RTU whose functional logic is determined strictly from electronics.

Corruption in India there is high amount of corruption that has triggered to the financial prices in the country and due to which people are not educated thus they have different perceptions and the country is not developing fast because of the difference between the views of science (which should be in a country) and the views of orthodox people which are very outdated and unable the country to develope
What is the differ between Replica and Archive in Lotus Notes?
In Notes, you can go to Help, then Help Topics, then search for information like this. Here's what Notes Help says: A replica is a duplicate of a database with the same replication ID number as the original database. Notes lets you create a local (offline) replica of any database you use. Through replication, Notes can keep a local replica identical with the database on the server, so you make changes once, but they appear in both places. Replication is the process of making replicas identical. Notes uses the replica ID number to locate and replicate all replicas of a database. A database copy (created by choosing File - Database - New Copy) does not have the same ID number as its original database, and doesn't replicate. A copy of a database file created through the operating system is a replica and does have the same ID number as the original database. Replication is a great tool to have when you're away from your office network, because working in a local replica is much faster than making the same changes over a dialup telephone connection. Replication also lets users on various networks in a variety of (physical) locations share the most current version of information in a database. An archive is a copy of a database you can create to store information no longer in use. Like a replica, an archive contains documents and design elements from the original database, but unlike a replica, an archive never sends any changes back to the original database.
Which are two activites are normally controlled by the northbridge part of the chip set?
In order to understand the Nortbridge you have to understand part of it used to be be the Memory Controller Chip (MCC) used to retrieve memory from RAM for the CPU. The MCC was upgraded to not only provide an interconnection between the CPU and RAM but also to be the interconnection between the CPU and other devices on the PC and was renamed the Northbridge. The Northbridge only deals with high-speed interfaces such as the connection to your video and RAM. The Southbridge works mainly with lower-speed devices such as the USB controller and the hard drive controllers. The Northbridge and the Southbridge architecture is called a ChipSet..
Which command-line tool can check replication consistency between replication partners and controllers?
Repadmin
What is the difference between outbound and inbound replication?
Outbound replication is when a domain controller transmits replication information to other domain controllers on a network andInbound replication is when a domain controller receives updates to the Active Directory database from other domain controllers on the network.
What does KCC create between multiple domain controllers within a site?
the site links are created by KCCKCC and Topology GenerationThe KCC is a built-in process that runs on all domain controllers. It is a dynamic-link library that modifies data in the local directory in response to systemwide changes, which are made known to the KCC by changes to the data within Active Directory. The KCC generates and maintains the replication topology for replication within sites and between sites.The KCC has two major functions:Configures replication connections (connection objects) between domain controllers. Each connection object defines incoming replication from a replication partner. Within a site, each KCC generates its own connections. For replication between sites, a single KCC per site generates all connections between sites.Converts the connection objects that represent inbound replication to the local domain controller into the replication agreements that are actually used by the replication engine.By default, the KCC reviews and makes modifications to the Active Directory replication topology every 15 minutes to ensure propagation of data, either directly or transitively, by creating and deleting connection objects as needed. The KCC recognizes changes that occur in the environment and ensures that domain controllers are not orphaned in the replication topology.
What is knowledge consistency checker KCC in windows server 2003?
The KCC is a built-in process that runs on all domain controllers and generates replication topology for the Active Directory forest. The KCC creates separate replication topologies depending on whether replication is occurring within a site (intrasite) or between sites (intersite). The KCC also dynamically adjusts the topology to accommodate new domain controllers, domain controllers moved to and from sites, changing costs and schedules, and domain controllers that are temporarily unavailable.
What is the KCC in AD?
The Knowledge Consistency Checker (KCC) is a built-in process that runs on all domain controllers and creates the replication topology for the forest. By default, the KCC runs at 15-minute intervals and designates the replication routes between domain controllers on the basis of the most favorable connections that are available at the time. The KCC creates replication connections between domain controllers in the same site automatically. When there is more than one site, configure links between the sites; the KCC can then create the connections automatically between the sites as well. from: http://technet.microsoft.com/en-us/library/dd277429.aspx
Which rodcs do not participate?
One of the new features receiving close attention in Windows 2008 is a new breed of domain controllers referred to as Read-Only Domain Controllers, also known as RODCs. The RODC hosts a copy of the Active Directory (AD) database like any other writable domain controller, but as its name implies, the contents replica of the domain database residing on the domain controller is read-only and write operations are not supported. It is equally important to mention that the RODCs do not participate in Active directory replication in the same fashion as writable domain controllers. The fundamental difference between RODC replication and the typical multimaster replication model between writable domain controllers is that RODCs replication is unidirectional. This means all changes from a writable domain controller are propagated to the RODCs. As a result, the RODC receives changes, but does not partake in or perform outbound replication with other domain controllers.
What is the main difference between circular and notification?

What component automatically creates replication links between domain controllers in the same site and schedules their replication activities?
Windows 2000 Domain controllers each create Active Directory Replication connection objects representing inbound replication from intra-site replication partners. For inter-site replication, one domain controller per site has the responsibility of evaluating the inter-site replication topology and creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. The domain controller in each site that owns this role is referred to as the Inter-Site Topology Generator (ISTG). Krishna Pothula Intersite Topology Generator (ISTG), which is responsible for the connections among the sites. By default Windows 2003 Forest level functionality has this role. ... Or the Distributed File System (DFS).
What is netlogon?
The Netlogon subkey stores information for the Net Logon service. The Net Logon service verifies logon requests, and it registers, authenticates, and locates domain controllers. Also, to maintain backward compatibility, Net Logon manages replication of the user account database to back up domain controllers running Windows NT 4.0 and earlier. For Windows 2000, Net Logon manages replication only when replication involves servers running Windows NT 4.0 and earlier. Net Logon for Windows 2000 does not manage replication between two servers running Windows 2000.
Replication that occurs between sites is called?
