Introduction
The local area network (LAN) can be used in the business for connecting the different
departments and floors of the organization as this will cover the small geographical area of the
organization. This report will cover the scenario of Footfall Field Marketing Ltd organization as
they want to connect their three separate floors in one building. This report will include the
discussion about the local area network in which LAN technologies will also be included. This
report will design the local area network for the organization along with the configuration of the
network devices. The report will also cover the testing of the designed network and after that its
maintenance will also be covered in this report. The report will also focus on the performance
and effectiveness of the network in the organization for their users.

Task 1
1.1 Critically evaluate different LAN technologies
LAN (Local area network) is mainly used for connecting the small geographical area which is
related to the organization with the help of cable connection. This LAN connection can be done
by implementing wireless connection by using the server link as this will make the data sharing
easy for the organization. There are various types of LAN technologies that are used by
organization while connecting their network. Following are the various types of LAN
technologies:
IEEE 802 standard: This LAN technology mainly deals in the MAN network metropolitan area
network and LAN (Local area network). This technology is effective for the organization as it
provides access method, high speed, media and topologies. Variable size packets in the network
have some sort of restrictions (Gong et al, 2015).
VTP: This network also known as the VLAN as the tracking protocol which is basically refer to
the Cisco proprietary protocol. Within the LAN technology VLAN information can be taken
with the VTP domain. This technology also helps to describe the VLAN in the Wide Area
Network (WAN). This is configured between the two layers of the networks. This will carry the
three versions.

DHCP: This term defines as the dynamic host configuration protocol that is the server protocol
which automatically provides the IP address with the IP host that mention the default gateway
and subnet mask (Otto et al, 2015). The main advantage of DHCP is that this will provide
TCP/IP model configuration to the clients in their network and this will also reduce or overcome
the administrative department workload.

FDDI: This term refers to the Fibre distributed data interface and this is mainly used by the
organization as this is the backbone of the LAN and through this organization can achieve the
100mbps speed within their network.

Token ring: This is the technology that is used in the network to gain the networking system but
this not wide. This can be used by the organization to expand or enhance their resource
utilization and performance level (Wang et al, 2016).
