Local Area Network Components and Architecture

This assignment provides an in-depth look at the various components that make up a Local Area Network (LAN). It covers the different types of LAN architectures, including hub, bridge, and network interface card, as well as their functions and applications. The presentation also explores the use of hardware devices to establish connections between computers and facilitate data communication. With references to relevant books and journals, this assignment is ideal for students and professionals looking to understand the basics of LAN architecture.

INTRODUCTION
Data communication can be defined as the exchange of digital data and information via
connection of two or more computers or network. So, in order to connect the physical and logical
components, there are three basic requirements are included such as Connections,
communication and services. This presentation will help in developing a LAN architecture of
different departments in Top Network Company. This report will discuss about the local areas
network that connected with the various devices for transmitting data one device to another.
This assignment will describe the typologies and protocol that applicable in the LAN.
LAN (Local area network)
Local area network is basically group of computers and other devices that share the
common information by using wireless link to server (Tang, J and et.al., 2018). It encompasses
the computers and peripherals connected to the different server within the geographic areas such
as commercial building etc. A local areas network server the two or more user at workplace.
LAN Networking comprises cables, Switches, routers, and other components which helps in
establishing interconnection of the internal servers of TNC (Top Network Company). Ethernet
and WiFi are primary ways to connect the local area network connections. Ethernet is
specifications of computers that enables to communicate with each other. WI-FI uses the radio
waves that connect to the LAN. Local area network is also including fiber distributed data,
interface and token rings etc.
a).All workstation Interconnecting devices
Typically, the application programs is kept on the local area network server. Many users,
who need an application to easily download by using local devices. TNC firm mainly used the
local areas network to connect with the different devices and share the information from one
device to another. This organization consists of mainly three departments that is Marketing,
Sales and Administration. In order to establish inter connectivity between all the departments for
the purpose of Inter-department Data-transfer (Usman and et.al., 2018). Each and every
departments contain their own router helps for a data transmission. Marketing department share
the information to the administration so that it requires for access the information by the LAN
admin to share the file from another department. All the department are connected to the main
server that collect, gather data on the server. It may used as web server because it provides the
safety and security in their internal application from outside access.

b). LAN Topology and Protocol
LAN Topology can helps in connecting the nodes on the logical network. Media-access
methods, transmission methods and typologies Used in LAN are IEEE 802.3, Token ring, Fiber
distributed data interface that allows the interconnection of different departments within
company. LAN generally uses Ethernet protocols in order to develop connectivity between the
computer devices of TNC. The LAN typologies are supported to the broadcast nature of network
and also provide the proper connectivity among the workstation of TNC organization (Jain and
et.al., 2018). Local area network station is used the physical connection that help for
communicating with each other. This organization mainly used the various type of typologies
such as bus, star and ring etc.
In star topology, all the devices are connected on the LAN and also interconnected with
the central devices that operate the entire devices. In bus topology, All the hardware devices are

connected with single cable. It is backbone of local area network therefore, one segment fails all
the devices are disconnected. In ring topology, Each and every nodes are connected by the point
to pint links that organized a proper circle. LAN protocol must used in the network which gain to
access the data from the server (Waqa and et.al., 2018). This protocol is to check the another
node for the purpose of data transmission. These protocols are the methods for transmitting the
data one node to another in quickly. TPC is also used the protocol in today's world, there are
some common protocol applicable in the local area network such as Asynchronous transfer
mode, fiver distributed data interface and token ring etc.
TPC organization is used the Star topology that connected with the central network to
distributed the data to another hardware devices. It is useful for collecting the data of company to
the server side.
HARDWARE
 Switch is a multi port bridge which is used to forward the data packets and eliminates all
such packets that contains error. LAN uses switches to increase the efficiency of data
transfer. It is a device that uses switching the hardware to checking and forwarding data
in the form of packets.
 Routers are the devices used in establishing inter connectivity computers present within
Local area. It routes the Data packets according to the IP addresses of such packets. IP
addresses helps in determining the sequence of delivering the data to destination (Chi,
Zhu and Li, 2018).
 Hub is basically termed as a multi-port repeater that helps in connecting multiple wires
coming from different stations. It may be Active hub or Passive hub. It is the central
devices that applicable in the network topology to repeat the signals allowing the network
for expanding with other stations.
 Network interface card is a type of circuit that inserted in the network station that allows
communicating with another workstation.
 Bridge is a hardware device to connect with tow or more Local area network. It also
operates the media-access layer for checking the data packets in proper manner.

 Network interface card is a type of adapter that installed to the ISA and PCI. This
hardware device is transmitted the bundle of data to another computer while allowing the
people to easily access the information and data simultaneously (Liew and et.al., 2018).
CONCLUSION
It can be concluded that Various networking components are used to establish a
connection between different computers. The presentation has created a clear understanding
about the development for LAN architecture. The presentation has a network using different
hardware that connects network between different computer systems. It summarized that Data
communication is exchanged the information by using hardware devices from one to another.
