Active Directory 2008-06-09 01:35:00 It is a centralized database where it contains the information about the objects like users, groups, computers, printers etc.AD is a centralized hierarchical Directory Database.AD is a searchable Database.2003 O/S. when installed (gets installed as a stand alone server) to promoting to D.C. We have to install A.D.Domain Controller (D.C.):A server where A.D. is installed is called D.C.Functionality of A.D.:Using A.D. we can organize, manage and control resources.It provides single point of administration.Purpose of A.D.: 1. Provides user logon authentication services.2. To organize and manage user A/Cs, computers, groups and n/w resources.3. Enables authorized users to easily locate n/w resources.Features of A.D.:1. Fully integrated security system with the help of Kerberos.2. Easy administration using group policy.3. Scalable to any size n/w4. Flexible (install/uninstall)5. Extensible (modify the schema)New features in 20036. Rename computer name & Domain names.7. Cross –forest t ...

IP-Address 2008-06-09 01:34:00 There are two versions of IP's1. IP version 4: offers IPs up to 4.2 billion (32 bit size)2. IP version 6: 128 bit size.IP address is used for identifying the system and provides communication.IP address is of 32 bits divided in four octets.Each Octet is of 8 bits, separated by a (.) dot.IP is a combination of Network ID & Host ID.Uses subnet mask to differentiate Network ID with Host ID.Subnet mask acts like a mask between Network ID & the Host ID.Numbers range between 0-255.Organizations responsible for assigning IPs to clients.IANA: Internet Assign Naming Authority.ICANN: Internet Corporation assigning for name Numbers.IANA has classified IP addressing into classes. Class A: 1-126(used in LAN/WAN)Class B: 128 – 191(used in LAN/WAN)Class C: 192 – 223(used in LAN/WAN)Class D: 224 – 239 (used for multi casting)Class E: 240 – 254 (used for experimentation & research)Class A:The first octet is reserved for network ID.The first bit of first octet is always (0).Class B: ...

Topology 2008-06-09 01:32:00 The way of cabling is called topology.The architecture of a network is called topologyThere are 2 Topologies :1) Network Topologies2) Logival TopologiesNetwork Topologies:E.g.: Bus, Star, Ring, and Mesh Topologies.Bus Topology:Components of Bus Topology:1. Co-axial cable (back bone cable)2. T- connectors3. BNC (British Network Connector)4. Terminator5. Patch cableDisadvantages of Bus:If anything goes wrong with backbone cable whole network is down.Follows a serial communication.Outdated these days.Star Topology:Star topology is an advanced version over bus topology. Where it uses either a hub or a switch, it uses cat5/6 cables.It uses connecters called (Recommend Jack) - RJ45Star topology offers faster data transfer or processing.Ring Topology: Ring topology is useful when we want redundancy (fault tolerance) we go with this type of topology.Ring topology uses a device called MSAU. (Multi Station Access Unit)It is a unit inside which a logical ring is formed. This ring ensures the avai ...

Network Devices 2008-06-09 01:32:00 Hubs, Switches, Routers and NICs.HUB: Hub is a centralized device provides communication among systems when we have more that 2 computers we need to have a device called hub to interconnect.Disadvantage of a Hub:1)When we want to transfer some data from one system to another system.2)If our network has 24 systems the data packet instead of being sent only to the destined system it is being send to all the network participants. (i.e. 24 systems.)3)Hubs follow broadcastingSWITCH: It is an advanced version over a Hub.The main benefit of switch is Unicast. Data packets are transmitted only to the target computer instead of all.Switch maintains a table called MIT (Mac Information Table.) which is generated as soon as we turn on the switch, which acts like an index table and easy the process of finding the networked system. MIT contains the port no, IP address and MAC address.MAC: (Media Access Control): It is an address burnt in the NIC by the manufacturer.MAC address is of 48 bits in the f ...

Types of Networks 2008-06-09 01:24:00 1)Local Area Network (LAN): Systems connected within the same geographical area is called LAN. A LAN can span 2 kilometers.Components of LAN:1. NIC (Network Interface Card)2. Cable – Co axial, cat5 or cat63. Hubs or Switches.2)Metropolitan Area Networking: MAN is a combination of LANs or WANS located and connected within the same city.Components of MAN:1. Router2. Brouter (Brouter is a combination of bridge or router)3. ATM Switches4. DSL connectivity (DSL – Digital Subscriber Link) ex: Star cables.3) Wide Area Networking (WAN): Interconnection of LANs or MANs located within the same geographical area or different area it depends on telecommunication services.Components of WAN: Same as MAN: ...

Introduction of Network 2008-06-09 01:21:00 NETWORK: A network is a collection of computers connected together.NETWORKING: It is a process of communication between the interconnected devices basically to share the network resources.Benefits of Networking:1. Share resources.i) Dataii) Hardware2. Share S/W3. Sharing of licenseNetwork is a collection of computers connected together to get benefited from networking.Networking: Networking is a process of communication among systems. ...
