IP Addressing
An IP(Internet Protocol) address is a unique identifier for a node or the host connection on an IP network.
An IP address is a 32 bit binary number usually represented as 4 decimal values , each representing 8 bits, in the range 0 to 255 (known as octets) seprated by decimal points. This is known as “doted decimal” notation. Example: 140.179.22 ....etc

Firewalls

+Sits between two networks
Used to protect one network from the other
It may be a hardware device or a software program running on a secure host computer
What does a firewall do?


-A firewall examines all traffic routed between the two networks to see if it meets certain criteria
-A firewall filters both inbound and outbound traffic.
-Firewalls can filter packets based on their source and destin ....etc

Introduction
LAN forms basis of all commercial,research,and data communication networks.Recently an increase in applications demand significantly higher band width. Ethernet is an easy to understand and extremely cost-effective technology. For these reasons, 98% of local area network (LAN) connections are now Ethernet based.
To meet this,high speed LAN types have been developed ,including a number of variations of basic ethernetLANs. CSMA/CD(carrier sense multiple access with collision detection) is used widely in ....etc

Introduction
Internet Data Centers (IDCs) are the computing centers of the
future. With the emergence of the global marketplace, organizations of all sizes are feeling the pressure to extend their Internet presence around the world, conduct business on a 24x7 basis, and provide customers with 99.999% availability ” all while reducing costs and keeping a sharp focus on their core business. Indeed, by utilizing IDCs and their economies of scale, companies can accrue the benefits of a world-class infrastructure at a f ....etc

virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devicesVLANs are created to provide the segmentation services traditionally provided by routers in ....etc

Definition
These are special purpose devices and computers that just transfer messages from one network to another. Before we look deep into the topic Virtual LAN's, let us see the basic devices used in the network backbone. They are

1. Bridges.
2. Switches.
3. Routers.
4. Gateways.
5. Hubs.

BRIDGES :-Bridges operate at the data page link layer. They connect two LAN segments that use the same data page link and network protocol.

SWITCHES :-Like bridges, switches operate at the data page link layer. Switches connect two or more co ....etc
