In Workgroup all users account such as user name and password Are Available in the SAM database. SAM Stands for Security Account Management Database.

Client Server:-Client Server network is also called Domain. In Domain there is one dedicated server; That Server Is Called D.C. D.C Stands for Domain Controller. In Client Server Network All users account such as user name and password are Available in the Active Directory database. Domain is a security boundary in the Network. there Are Many Benefits of Domain, Such As—

A.     Single logon

B.      Single User Account

C.      Centralized Management

There are three scopes of Network:

LAN:-LAN stands for Local Area Network. In a fixed area all of the computers are connected to each other, it is called LAN. In LAN we do not use any third party Service Provider Network such as Telephone Line, Internet and Satellite.

WAN:-WAN stands for Wide Area Network. Across the world all of the computers are connected to each other, it is called WAN. In WAN we use Third Party Service Provider Network such as Telephone Line, Internet and Satellite.

MAN:-Man stands for Metropolitan Area Network. MAN is a child of WAN because in a metropolitan city all of the computers are connected to each other, it is called MAN. In MAN we use Third Party Service provider Network such as Telephone Line, Internet and Satellite.

(Example:-Suppose I have a company that name is ABC Pvt. Ltd. held in Delhi which has four branch offices First is South Delhi, Second is East Delhi, Third is North Delhi and Fourth is West Delhi. All the branch offices are connected to the main office with the help of Third Party Service Provider Network such as Telephone Line, Internet and Satellite, it is called MAN.)

NIC:-NIC stands for Network Interface Card...

PXE:-PXE stands for Pre Execution Boot Environment. It is generally use in RIS.

PXE and Non-PXE:-Boot roam is available on PXE Card. Boot roam is not available in Non-PXE Card.

Cable:-Cable is a medium that creates a Network and carry the signals between computers in the Network. There are two types of cable:

2.      Twisted Pair Cable:-Twisted Pair Cable is also called 10Base T. There are four pair in this cable White - Green, White - Blue, White - Brown, White - Orange. There are two types of Twisted Pair Cable:

A.      UTP:-UTP stands for Unshielded Twister Pair. There are no mass shielded on the wire.

B.      STP:-STP stands for Shielded Twisted Pair. There are a mass shielded on wires.

3.      Coaxial Cable:-Coaxial Cable just like as a normal TV cable. In coaxial cable one is copper wire that is located in the central location of the cable then after a plastic coating then after shielded with mass and then after upper coating (Black Coating). There are two types of coaxial cable.

A.      Thin Net Coaxial Cable:-Thin Net Coaxial Cable is also called as 10Base 2. 10 stand for 10 MBPS and 2 stands for up to 200 meters.

There are two types of device in the network—

1.      DTE Device--- D.T.E Stands for Data Terminal Equipment. As for example—P.C, ROUTER

2.      DCE Device---D.C.E Stands For Data Communication Equipment. As for Example—HUB, SWITCH, MODEM

Straight Cable:-When we connect Two Different Devices, Such as DTE to DCE Device in that cases we will use straight cable as for example Computer to Hub, Computer to Switch.

Cross Cable:-When we connect two similar devices, Such as DTE to DTE, DCE to DCE in that case we will use cross cable as for example Computer to Computer, Hub to Hub.

Topology:-Topology is the way of connecting the computers. Topology requires two or more computers. There are five types of Topology.

Bus-Topology:-In this Topology all of the computers are connected to a single Wire Such As--coaxial cable. In Bus-Topology if the cable is break from any where then the all network is down. In Bus-Topology the network speed is divided among the computers. In this topology we use BNC connector. BNC stand For Barrel Net Connector.

Star Topology:-In this Topology all of the computers are connected to a central device such as Hub, or Switch. In star Topology if one computer Will failed in that case my network will be still working properly. In this topology we normally use UTP cable and RJ-45 connecter. RJ stands for registered jack.

Ring Topology:-In this Topology all of the computers are connected to own next computer and the last computer is connected to first computer. In this topology if one computer will fails then my whole network are down. (Cable Used-? Speed - ?).

Mesh Topology:-In this Topology all of the computers are connected to each other computer in the network by a separate cable and Separate NIC card. It is also called complete Topology.

Hybrid Topology:-When we will connect two or more same Topology To a single different Topology, it is called Hybrid Topology. There are two types of Hybrid Topology:

A.      Star wired Bus

B.      Star wired Ring

Technology:-The rate of data transmission depends on your Network Technologies. There are many types of Network Technologies Are Available in the World---

Ethernet:-Ethernet is a popular LAN Technology that uses CSMA/CD.

ATM:-ATM stands for Asynchronous Transfer Mode. ATM is a packet switching network that sends fixed length packets over LAN or WAN. The packet size is 53 bytes in which 48 bites data and 5 bytes for address.

Frame Relay:-Frame Relay is a packet switching networks that sends variable length packets over LAN or WAN.

FDDI:-FDDI stands for Fiber Distributed Data Interface. The rate of data transmission is fast in this Technology. There are two types of Ring in this Technology. First is Primary Ring and second is Secondary Ring. Normally the data is sending from source computer to destination computer through the Primary Ring if Primary Ring Will Be fails then the data Will Be sending through the Secondary Ring.

Hub:-Hub is a central device in the network that is used in star topology. Hub does the broadcasting. The rate of data transmission is slow in the network by using Hub.

Switch:-Switch is a central device in the network that is used in star topology. Switch does the conditional broadcasting. The rate of data transmission is fast in the network by using Switch.

Router:-Router is a device that provides the connectivity between two or more different network id.

Gateway:-Gateway is a device that provides the connectivity between two or more different network id. Gateway works on different network architecture.

Repeater:-Repeater receives the signals and retransmits it to original strength in the network.

IP Address:-IP Address is a unique identifier in the network from one computer to anther computers. IP Address Is A Combination Of Network Id + Host Id.

Remote Administration Mode:-In this mode at a same time By Default maximum two administrators can connect remotely to the server and manage it.

Application Server Mode:-By this mode user allow to run remotely one or more applications on the Server.

Leased Line:-Leased Line is a point to point connection. When we connect 24 hours a day to the Internet then we have a best option to choose the Lease Line because it is cost effective(no Costly)

ISDN Line:-ISDN Line is not a point to point connection. ISDN networks extend from the local telephone exchange to the remote user in the network. By ISDN Line the rate of data transmission is fast. The data are sending in digital form not in analog form. In ISDN scenario both side (client side and server side) ISDN Modem is necessary.

After verifying user name and password the Remote Access Client connect to the RAS Server and further connect to the Internal Network.

VPN:-VPN Stands for Virtual Private Network. In this process Remote Access Client connect to the VPN Server via Internet. By this process the communication is very secure and the data are sending and receiving in tunneling form.

DNS:-There are two types of DNS Query:

Iterative Query:-When a client Query to the DNS Server and if my DNS Server is having the best result then it will give the best result to client in the network otherwise it will send a message not found, it is called Iterative Query.

Recursive Query:-When a client Query to the DNS Server and if my DNS Server is having the best result then it will give the best result to client computer otherwise it forward the client Query on own behalf to the Root DNS Server and it will give the complete result to the client Computer in the network, it is called Recursive Query.

CA:-CA stands for Certification Authority. CA provides the secure communication between two or more computers in the network. There are four types of CA:

Enterprise Root CA:-

Enterprise Subordinate CA:-

Stand Alone Root CA:-

Stand Alone Subordinate CA:-

Enterprise Root CA and Enterprise Subordinate CA required the Active Directory but Stand Alone Root CA and Stand Alone Subordinate CA do not require Active Directory.

Narrowband Radio Transmission:-In Narrowband Radio Transmission user tunes both the transmitter and the receiver to a certain frequency. Narrowband Radio Transmission does not require a clear line between both devices. Radio and FM is the example of Narrowband Radio Transmission.

PPTP:-PPTP stands for Point to Point Tunneling Protocol. It is used in RAS connectivity. PPTP enable the secure transfer of encapsulate data between a PPTP Client and a PPTP Server across the Internet. PPTP uses MPPE (Microsoft Point-to-Point Encryption) to encrypt the data.

L2TP:-L2TP stands for Layer Two Tunneling Protocol. It is used in RAS and more secure then PPTP. L2TP enables the secure transfer of encapsulate data between L2TP Client and L2TP Server across the Internet. L2TP uses IP Sec (Internet Protocol Security) for Encrypt the data.

Three Way Hand Shake:-TCP is a reliable Protocol. When two computers communicate that using TCP, firstly establish a connection before the exchange of data, it is called session. Two computers establish a session by a process that is called Three Way Hand Shake. There are three steps in Three Way Hand Shake process:

A.      The source computer initiates the connection by transmitting the session information.

B.      The destination computer responds with its session information.

C.      The source computer receives the information and sends an acknowledgement.

Host Name:-A Host Name is a user friendly name that is given by us to a computer to identify him. The Host Name is a 15 byte or up to 255 character length name.

NetBios Name:-A NetBIOS Name is a 15+1 byte name in that 15 byte is host name that is given by us and 1 byte is generated by computer automatically.1 Byte Depends on That Computer Are Providing Which Kinds Of services In the Network.

Web Server:-A server computer that provides the services related to web site/Internet is called Web Server.

Class-full IP Address:-All the IP Addresses are divided into five classes class A, B, C, D and E. All the classes having a default subnet mask according to its class. So the IP Address that is given with its default subnet mask is called Class-full IP Address.

Class-less IP Address:-All the IP Addresses are divided into Five Classes class A, B, C, D and E. All the classes having its default subnet mask. When we change the default subnet mask of an IP Address by the help of sub netting and super netting, it is called Class-less IP Address.

Driver Signing:-Sometimes when we install a new driver/software on the computer then its installation process is overwrite some system files and damage or creating some problem with our operating system. To stop this thing windows 2000 have a feature i.e.  Driver Signing. Driver Signing check the driver/software is signed by Microsoft or not. There are three Options in Driver Signing:

Ignore:-In Ignore Windows do not check the signed or unsigned driver and install the driver normally.

Warn:-In Warn Windows check the driver is signed or unsigned and give a warning massage during installation for unsigned driver.

Block:-In Block Windows never install the unsigned driver.

Permission Inheritance:-All the permissions is assigned to a folder is automatic apply on its subfolder or files, it is called Permission Inheritance.
