The document provides a budget and plan for setting up a network for a part time group, including details on types of networks like LAN, WAN, and wireless networks. It discusses hardware and software requirements like switches, routers, cables, and access points. The budget section lists proposed equipment purchases like a multi-function device, wireless cards, and an ADSL subscription from MWEB to connect the network.

2. Types of Networks
• Local Area Networks • LAN is a group of interconnected computers
Under the same administrative control
(LAN) Can be as small as a single local network installed
in a home or small office
• Wide Area Networks • WAN connects LANs in geographically separate
locations, covering a much larger area than LANs
(WAN)
• WLAN uses devices to transmit and receive data
using radio waves.
• Wireless LAN (WLAN) WLAN has a limited range. Ideal for home and
small office areas.
• Peer-to-peer Share files and resources
• Peer – to – peer There is no central control
Each computer must have separate security
measures for data protection.
• Client/Server • Client/Server provides security and control
maintained by Administrators
The client requests information or services from the
server and the server provides the requested
service or information.

3. Local Area Networks (LAN)
5 Types of LAN Topologies
• Bus Topology • Bus topology connects each computer on a
single cable and ends with a terminator.
Only one computer can transmit data at a
time or frames will collide and get
destroyed.
• Ring Topology • Ring Topology, computers are connected in
a physical ring. A token travels the ring
stopping at each computer to check if it
wants to transmit data.
• Star Topology • Star Topology has a central point, usually a
hub. All computers connect to the hub.
• Hierarchical Star is used for larger networks
• Hierarchical Star by connect additional hubs to the original
hub allowing more star topology networks to
Topology connect to each other.
• Mesh Topology • Mesh Topology is a type of connection
where all devices connect directly to each
other.

4. Hardware / Software Requirements
• Switch • A Switch has several ports and refers to a
table of Mac Addresses to determine which
port is used to forward a frame.
• A Hub extends the range of a signal by
• Hub receiving and re-generating it to all ports
• A Router connects entire networks to each
other using IP Addresses to forward packets
• Router to other networks. Routers contain a table of
IP Addresses along with optimal routes to
other networks.
• Wireless Access Points provides network
• Wireless Access access to wireless enabled devices such as
laptops, PDAs and cellphones. It uses radio
Point waves to allow communication between the
devices.

5. Hardware / Software Requirements
• Multi-Purpose Device • Multi-purpose Device performs more than one
function. It combines a router, switch and wireless
access point into one device.
• Twisted pair cabling • Twisted Pair Cabling is a pair of wires that form a
circuit to allow data transmission. The twists in the
cable provide protection against crosstalk.
Unshielded Twisted Pair has four pairs of wires and
relies on cancellation effect for reduction of
interference caused by EMI and RFI. Range of 100
metres.
Shielded Twisted Pair has each pair of wires
covered in foil for better shielding and all 4 pairs are
wrapped in foil or a metallic braid.
• Co-Axial cables • Co-Axial Cable has a copper core wire surrounded
by heavy shielding.
• Fibre-Optic • Fibre-Optic is a glass strand enclosed in a sheath.
It uses light to transmit information over long
distances.
