Introduction:
LAN is a local area network which provides the service medium size area. It offered service in
school, college, small office or firm. LAN managed sharing, communication, and exchange in the
network. It may be useful for The FootFall Field Marketing organization. LAN will offer
interconnection between offices and their departments. I have designed a local area network
report for the FootFall Field Marketing organization. There are four sections in the report.
In the first section, I will be describing a different type of technology Technologies such as wired
and wireless LAN network. Then, virtual area network, the traffic intensive services, and LAN
components will be discussed which help to design the network. In the second section, I will be
creating LAN infrastructure according to client requirements and evaluate of LAN components.
In the third section, I will be implementing and configuration the LAN network. I will be
implemented security in the LAN Network and test the network. In the fourth section, I will be
explaining tools that will be monitoring and troubleshooting the LAN network. Then,
performance, reliability, and security issue of LAN network will be resolved and measured the
LAN performance.

LO1 Understand the impact of LAN technologies
A.C 1.1 critically evaluate different LAN technologies
LAN is a local area network that built for the sharing of service and resources like as
applications, files, internet access, games, email, and printers. LAN network designs for the
home, office building, and school because it provides the service where a group of computers
near each other. In the Traditional network offered Single LAN service but Modern network
offered a number of LAN service in the building (Mitchell, 2017).
Type of LAN Network:
Wired LAN Wireless LAN
Wired network works on high bandwidth but
provides the low bandwidth variability.
Wireless network works on Low bandwidth
but provides the high bandwidth variability.
It can listen on the wire. It has hidden terminal problem
It uses high power machines and resources
machines.
It uses Low power machines and resources
machines.
Packet delay is low. Packet delay is high.
Wired LAN needs more security. Wired LAN needs more proximity.

Ethernet IEEE 802.3
Wired Network supports Ethernet IEEE 802.3 standards which defined for the physical layers
and MAC layer (Media Access control layer of the data link). It makes the physical connection
between nodes on the copper wire and fibre wire. LAN network used CSMA/ CD methods
Kurose and Ross, 2007).
Wi-Fi IEEE 802.11
IEEE 802.11 is a standard for the networking that is defined for the wireless network. It works
on Media Access Control, Quality of Service, and wireless networking security (Singh, 2017).

Virtual LAN Network:
Virtual local area networks is a switched network that offered segmentation services which
offered by routers during the LAN configurations in the traditionally LAN network.
Segmentation services are performed by the functions, applications, and project team. VLAN
does not need the physical location of users but runs on different architectures. VLAN network
used switch port which shares for the broadcasts. It improved the overall performance of the
network.
