Introduction
LAN is defined as Local Area Network that is used for the connection of internet generally in
minor geographical based areas that are offices, houses, or mainly to a floor. It is defined as a
set of hardware-based instruments that creates networks and for its further communication.
The marketing-based company and sales of football demands for expanding its network to at
least three floors segregated in several departments that are IP support, HR, customer services
etc. Total working employees are twenty-eight in number comprising of all available
departments and all of them are interconnected with the entire developed system.
The report further includes LAN based technologies discussion along with its performance
and services. Several terms regarding the LAN reliability, security and its performance are
also being described. Secondly, it includes the model and completes an evaluation of the
network or LAN to determine whether the network is suitable or not. Thirdly it comprises of
network implementation and even describes the raised issues or problems.

LO1- Understand the impact of LAN technologies
1.1 critically evaluate different LAN technologies
Local Area Network (LAN)
Local area network also called as LAN is a set of networks which can be used in the specified
location for connecting PCs to such a network that shares a common line with the server.
LANs are mainly used in homes, organisations and institutes. The LAN can be of several
types
 Wired
 Remote or wireless
 Combination of the two
The standard LAN that is wired utilises Ethernet so as to entirely associate all the gadgets
together. Remote based or wireless LANs generally utilised the Wi-Fi based network. Some
disadvantages of LAN based networks are that it can only be used in small areas.
LAN and its types
LAN is mainly divided into two possible types that are wired and remote or wireless.
Generally, all private based LANs uses their own router in order to create a system and tackle
with all various associated gadgets. The working of the router includes associating of focal
points and empowerment of the gadgets like Tablets, mobile phones, PCs so that the
communication becomes easier with each other. In the case of LAN, a PC can be converted
into a central point for access and even behaves as a server that provides several machines so
as to access all located files on servers. Also, multiple LAN is combined in order to create a
bigger LAN.

Figure 1: Local Area Network
Wired LAN uses IEEE standards that is Ethernet IEEE 802.3 and Wireless LAN uses IEEE
standards that are Wi-Fi IEEE 802.11 (Waliullah, Moniruzzaman and Rahman, 2015).
Technologies of LAN
LAN based technologies are mainly used for connecting several systems and this requires the
proper connection of data in networks that are defined as local area network. It uses several
standards in networks that are IEEE 802.11 wireless, IEEE 802 LAN and others.
IEEE 802.11 wireless Standards
802.11 define IEEE standards especially for wireless based or remote system networking.
Several determinants of wireless networking system used to exist under the pennant of
802.11. All model of 802.11 Wi-Fi works under the ISM recurring bands that are Industrial,
Scientific and Medical. Many different conveyor guidelines are being described that are used
commonly. Several standards are there that are 802.11a, 802.11b, 802.11g. The standard of
802.11n is defined as the recent delivering rates of raw data nearly up to 600 Mbps. Each of
the distinctive gauges is defined with some diverse highlights which were further propelled at
different circumstances. The acknowledged standard mainly for 802.11WLAN was 802.11b.
IEEE 802.3 wired LAN Standard

IEEE 802.3 comes out to be the widely and mostly used computer networking standards and
means for communication of data. The IEEE here stands for the Institute of Electrical and
Electronics Engineers standards.
The standard of Ethernet is being utilised for higher time and it must be refreshed
consistently in order to meet all requirements of the technology grows. The speed of
information related to communication and Ethernet use to rise consistently and the IEEE
802.3 velocities are being expanded relatively. Ethernet is generally familiar to almost many
because the connection of Ethernet is being utilised in wired PCs that are available. It mainly
provides a backbone to several other frameworks of data based communication that is both
small and substantial (Crow, Widjaja, Kim, and Sakai, 1997).
Virtual LANs, its working, advantages and types
VLAN also defined as Virtual LAN is referred to as logical based sub-network that combines
several devices from various defined local area network. Various physical based networks
support the VLAN that is Ethernet and Wi-Fi.
At the time LAN uses to receive some data from the workstations and it allows the data
labelling with an identifier of VLAN that showcase the VLAN that delivers crucial
information. This entire process is known as Explicit Tagging. It becomes conceivable
sometimes to decide in which VLAN it is easy to place the data for utilizing implicitly related
tagging. In order to determine the data tagging capacity for the utilization of technique, it is
required to keep a bride where the database is regularly refreshed consisting of VLAN
mapping and determines the tagging which is being utilised. Bridges are used with a need to
determine the capacity of the created database and in order to ensure that all scaffolds of
LAN have the similar kind of data in its entire database. After the bridge, used to determine
the flow of information and several LAN related activities the things are properly being
defined. Scaffold determines the information flow and determines the need for the addition of
VLAN identifier to particular information and then it is required to be sent. The event is all
about the transferring of information to the gadgets which plan for the execution of the
VLAN, an identifier of VLAN which is used to add information. If there is a need to operate
a gadget that doesn’t have any learning regarding the usage of VLAN then the information is
sent via bridge without using VLAN identifier.
