coaxial applications amp performance - analog plus digital phone networks- cable tv networks- traditional ethernet lans- power line and home
q unshielded twisted pair - transmission media- a most common kind suitable for both voice and data transmission- categories are determined by chain
q define guided media- offers a conduit from one device to another- signal is directed as well as contained by physical limits of medium-
q what is transmission media- actually situated below the physical layer- directly controlled through the physical layer- data should be converted
q show the application layer responsibilities- make possible user access to the network- user interfaces as well as support for services such as
q host system in tcp-ip model- standards adopted because of widespread use like internet- the protocols came first plus the model was really just a
qrole of host systemhosts on osi implementations dont handle network operations simple terminal but tcpip hosts participate in most network protocols
q focus of reliability control- implementation of the osi model puts emphasis on providing a reliable data transfer service while the tcpip model
q subnet layer of the tcp-ip modelthese two layers of the osi correspond straight to the subnet layer of the tcpip model majority of the time the
q show data link and physical vs subnet- data link layer the function of the data link layer is -offers for the control of the physical layer and
q explain tcp-ip routing architecture the tcpip routing architecture looks extremely much like the osi routing architecture hosts utilize a
q describe osi routing architecture end systems ess as well as intermediate systems iss use routing protocols to distribute -advertise some or all of
q osi network layer addressing isoiec and ccitt mutually administer the global network addressing domain the primary hierarchical decomposition of
q define internet network address the internet network address is additional commonly called the -ip address it consists of 32 bits a few of which
q diffrence between network vs internet layers- similar to all the other osi layers the network layer provides both connectionless and
q comparing transport for tcpip and osi model- the features of tcp and udp defined at tcpip transport layer correspond to many of the requirements of
q show upper layers of tcp-ip modelthe session layer - the session layer allows two parties to hold ongoing communications called a session across a
q tcp-ip and osi differences - tcpip combines the presentation and application layers- tcpip combines the osi data link and physical layers into 1
q show the tcpip and osi similaritiestcpip and osi similarities - both have layers- both have application layers- have comparable transport and
q summary of osi model- there was no standard for networks in the early period and as a result it was difficult for networks to communicate with each
q explain physical layer of osi reference model- the physical layer deals among the physical characteristics of the transmission medium- it defines
q what is data link of osi model- the data link layer offers access to the networking media and physical transmission across the media and this
q what is network layer of osi model- describe end-to-end delivery of packets- defines logical addressing thus that any endpoint can be identified-
q define transport layer of osi model- the transport layer regulates information flow to makes sure end-to-end connectivity between host applications
q explain session layer in osi model- the session layer defines how to control start and end conversations called sessions between applications- this
