Internet Protocol
Internet layer of that same TCP / IP system is IP dominated by other protocols. The IP
address is a logical address for each host in the network and every interface of a router. All
host networks are grouped in the same street-like address range, where each host has a unique
house or mailbox address from that range. Each network has a distinct variety of addresses
and routers connecting these networks in layer 3.
As IP gets TCP or UDP sections, it also includes an origin IP address header and targets IP
address. The PDU is known as a packet. When a router gets a packet, the target code in the
header will be checked and forwarded to the target network. Before reaching the target
network, the packet may need to cross various routers. It is called a trip every router that it
has to pass (Freeccnastudyguide 2015).
Network Access layer
TCP / IP Model network access level refers to the OSI reference model's datascendance link
and physical levels. It describes the procedures and equipment necessary for a computer to
link and supply information to a physical network. For delivery within a physical network,
packets from Internet layer are sent through the Network Access layer. Another network host
or router can be the target itself for further transmission. Therefore, the Internet element
views the full Internet network, while network access layer is restricted to level limit which is
often determined by a floor 3 device such as a router.
A big amount of procedures are included in the network access section. Ethernet is the most
popular protocols used when the physical network is a LAN with its many variants. On the
other hand, protocols like the point-to-point protocol (PPP) and the framework relay are
common when the physical network is a WAN. We examine Ethernet and its variants in this
chapter.
Sol. 2
The telephone interaction between both prime ministers can be understood using following
diagram.

Figure 1: Telephone communication
Communication using the telephone between the French and Chinese prime minister
implemented using this connection setting and it goes as mentioned in the above diagram
with the below-described process.
1. French Prime Minister will use Telephone to connect Chinese Prime Minister
2. Telephone will be picked up by Chinese English Translator
3. Chinese English Translator will provide information to Chinese Prime Minister
4. Chinese Prime Minister will reply to the Chinese English Translator
5. Chinese English Translator will Telephone
6. Telephone calls will be picked up by French English Translator
7. French English Translator will provide response to French Prime Minister
8. French Prime Minister will reply to French English Translator and process will go on.
