SECOND meeting

 in our second meeting  i learn the OSI model use for solving and tracing problems.

                          OSI  MODEL
 7.Application
6.presentation
5.session
4.transport
3.network
2.data link
1. physical


application- this is a deal with networking application.

presentation-is responsible for presenting the data .

session- establish, manage, and terminate the data.

transport- this layer breaks up the data from the sndding host and reassembles it in the reciever.

network- referred to as the "CISCOLAYERS"  end to end delivery

data link- MAC address
               use by switch  (PHYSICAL ADDRESS)

physical layer-defines  physical media.

  3 TYPE OFTRANSMISSION
     unicast
     multicast
    broadcast


 broadcast domain- any device w/ in the group.
collision- the effect of two nodes sending transmission.
collision domain- the network area in etherned over which  frames  that have collided will be detected.

first meeting

network management  IT2

Hmmmmpp in our first meeting i've learned some of the topic like the kinds of  TOPOLOGY
*LOGICAL TOPOLOGY- which defines how the media is accessed by the host for sending data.
*BUS TOPOLOY- IT IS A use a sigle backbone cable that is terminated at the both end.
*RING TOPOLOY-connects one host to the next and the last host to the first.
*STAR TOPOLOGY- connect all cables   to a central points of connections .
*EXTENDED STAR TOPOLOGY- links individual stars together by connecting the hub and switches.
*MESH TOPOLOGY-PROVIDE AS MUCH PROTECTION  as possible from interruption .

 and the TYPES OF NETWOR
    -WAN's- wide area network
       WAN's  operate over a large geographical area. USE a router,communication server,                          modem,.
-LAN's- local area network

-MAN's- metropolitant area network


SWITCH-  add more intelligence to data transfer management.
HUB- connect a group of host.
ROUTER- are use  to connect network together.
