Understanding OSI Model, TCP, ARP and Network Design Topology

Question 1
OSI model is protocol that is autonomous and modernized, categorized as a communication gateway or
message between the system and end customer it has a vertical approach and ensures delivery of
packets in a network. While TCP relies upon standard processes around which the Internet is
created(Bedaride,2013). It is a communication convention which grants relationship of hosts over a
network framework or a system. With this no assurance of packet conveyance and has an approach
which is horizontal.
OSI model is mostly used with describing networks since it provides deep descriptions of layers within
the network.
Question 3.
Address Resolution Protocol is a protocol used by the Internet address Protocol (IP) mainly IPv4, to plot
and sort out addresses to equipment’s that have tendency to be used by a data interface convention.
(Chen,2009)The convection works underneath the network framework layer as a touch of the interface
between the OSI framework and OSI associate layer. It is used when IPv4 is used over Ethernet MAC.
Arp cache - is a store for data that is used to connect an IP convey to a MAC address for a physical
machine or a device in a close-by network framework. The ARP store can store data for both remote
and LAN connection, and routes packets to endpoints.
Question 4
a.
introduction
The growing interest for advanced network system has made network scientists to design and organize
models fit high gauge of organized structures to end customers. The network framework establishment
setup ends up essential part for a few IT association late layers.(Cho,2008) A critical system plan or
network design thought for organization will be modernized to help future developments; solid and
adaptable systems. This needs the planner to prioritize the users with one kind of circumstance, mainly
the current innovation, invention ,application, and information engineering.
Design
The design of the network is very similar internet routing works message is split into packets that are
transferred within the network devices. (Fall,2011)There are different types of protocols that will be
labeled to different types of the network devices such that they can be uniquely identified or
differentiate from each at each network other within the network. The different types of network
devices that will be implemented in the network include computers, routers, hubs and switches. In the
network there will be different type of work station and each work station can have different network
topology. The most suitable topology is to be chosen among the many topologies.
