        Hi mga ka blogger....this is our first meeting in I.T.
-2 Network Management/Principles....I hope you enjoy while reading my post.

Our topic is all about Networking- which means communicating through device.


ICONS:

•           ATM Switch  
•           Router
•           Switch
•           Comm Server
•           ISDN Switch
•           Bridge
•           PC
•           Laptop
•           Phones
•           File Server
•           Hub
•           Modem
•           Phone Customer
•           Network Cloud
•           Building
•           Home Office

Data Network is a sharing data through the use of floppy disks is not an efficient or cost effective manner.

       Businesses needed  a solution that would  successfully address the Three Problems:

• How to avoid duplication of equipment and resources.
• How to communicate efficiently.
• How to set up and manage a network.

                                           Two classification of Devices:

• End-User Devices:like computer,printers,file server,scanners,hub.
• Network Devices:like modem,ISDN Switch,router,switch.

      Network Interface Card (NIC) is a printed circuit board that provides network communication         capabilities  to  and from a Personal Computer.Also called LAN Adapter.


Network Topologies defines the structure of the network.

         Two Types of Network Topologies:

• Physical Topology- the actual layout of wire  or media.
• Logical Topology-defines how the media is accessed by the  facts for reading data.

Bus Topology -uses a single backbone cable that is terminated at both ends.

Ring Topology- connect one host to the next and the last host to the first.

Star Topology -connect all cables to a central point of concentration.

Extended Star Topology -links individual  stars together by connecting the hubs  and/or switches.The    topology can extend the  scope and coverage of the network.

Mesh Topology-meshy
                          -is implemented  to provide  as much protection as possible from interruption of service.
