second meeting
on our second meeting we continued the topic from the last lesson about virtual private network (VPN) is a private network that is constructed with in a public network infrastructured such as global internet using VPN a telecommuter can access. And we discuss also about the OSI model or open system interconnect. There are seven osi reference model.
* Application-this layer deal with networking applications ex.( email, web browsers and etc.)
*Presentation- is responsible for presenting the data in the required format which may include (code formating,encryption, compression ,PDU- formatted data)
*Session- establish, manage and termenates session between two communicating host.
*Transport- breaks up the data from sending host and then reasemble it in the receiver.
*Network-sometimes referred to as the "cisco layer"
-provide logical addressing that routers use for.
*Data link-provides reliable transitnof data across physical link.
*Physical- physical media through which the data.
And we discuss also about the type of transmission.
*Unicast- specific host
*Multicast-selected host
*Broadcast- connect all host
Broad cast domain-a group of devices recieving broadcast domains frames initiating from any divice with in the group.And after the discussion Mr. Dosejo give as a short but difficult quiz.

First meeting
hai everyone!!!!
In network managemement i learned about many things about networking like data networks. Sharing data through the use of floppydisks is not efficient or cost effective manner.Business needed a solution that would succesfully adress the ff. three problems.How to avoid duplication of equipment and resources. How to communicate efficiently and the last is how to set up and manage a nerwork.And also we discuss kind of network devices.
*End- user devices- include computers, printers,scanner and other devices that provide directly to the user.
*Network devices-include all the devices that connect hub,router,switch, modem that connects the end user devices together and allow them to communicate.
*Network Interface Card( NIC)- is aprinted circuit board providesnetwork communication.
* Host- end user devices
*Hub-connects a group of host
*Switch-switches add more intelligence to data transfer managemet.And we have a topic about kinds of Topology. Topology called by network there seven kinds of topology.
1.Network topologies- defines the structure of the network
2.Logical topology- which defines how the media is accessed by the host for sending data
3.Bus topology- a bus topology uses a single backbone cable that isterminated at both ends.
4.Ring topology- connects one host to the last host to the first.
5.Star topology- connects all cables to a central point of concentration.
6.Extended Star topology- links individuals star together by connecting the hubs and switches.
7. Mesh topology- is implemented to provide as much protection as possible from interruption of service.and last but not the list we discuss about network.Like Lans, Wans, And Mans.
