INTRODUCTION
Computer network is known as digital telecommunication network for sharing various
king of information and other resources between nodes. Through these nodes all computer
devices are connected in the network. This is important for the organizations to have a computer
network in order to gain higher performance with efficient speed (Johannisson, 2017). This
report is providing brief various telecommunication and network devices that are used in the
computer network along with their specification and pricing. A proper network diagram also will
be provided n the report that can be implemented in the organization.
MAIN BODY
A computer network within an organization is consists of various technical equipments
that can help the organization to perform various typical operation with high efficiency and
quickly. Computer network is consist of various devices that can be used by the organization in
the computer network which are- Routers, Servers, Gateways, Cabling, Access Points, Virtual
Private Networks, Firewall, Anti-spyware, wireless access points, repeaters, switches and
Network topologies. This all devices are required to efficiently provide better communication
and data transfer between the devices.

In a computer network wireless access point is known as just as access point. This device
allows the other wireless devices to get connected to a wired network. This device is usually
connected to the router in a computer network. By using this device various wireless phones and
2

laptops can be provided with the access to the particular server or computer network. The main
advantage of this Wireless Access Point is, it is configured with multiple input and multiple
output technology. This provide high flexibility to the computer network. The most suitable
wireless access point for computer network is Cisco WAP371. Some of the main features of
this wireless access point are-

9. Cable that is used with this WAP is 5e and much better.
10. Reset button is provided to reset the password setting.
11. Weight of this device is very low.
VPN Router
VPN router is a device that is used in the computer network to connect various wired or
wireless devices to the internet through virtual private network (Raider and Krackhardt, 2017). If
the devices that are connected to the network do not support the VPN then also these devices
could be connected thorough virtual network using encrypted internet traffic.

Wires
there are three main types of wires that are used in networking:
 Twisted pair cable: these are one of the most common type of wires that are used for
connecting computers, ethernets etc.
 Coxial cable: These types of wires are mostly used for television but they are rarely used
because they are quite difficult to be installed and managed.
 Fibre-optic cable: this type of wire support very high bandwidth that can also help in
speeding up network speed and connectivity.
Network Topologies
There are different topologies are used in the computer network to connect various
devices and work stations together to gain maximum performance in the network. In this
topologies systems are connected together in different formations. The arrangement of the
system is based on the structure and size of the network system that is required to develop (Kuss,
and Griffiths, 2017). Bus Topology, Mesh Topology, Star Topology and Ring Topology are
most common topologies that are commonly used in the business organization and personal use.
Bus Topology- This is one of the easiest form of computer network topology that is most
common in the small and medium size organization. In this topology work stations are connected
together with nodes that are connected to the main cable through the drop cables. This topology
is used to design the Cisco devices based computer network system.
Advantage
 Easy to install.
 Size of cable required in this topology is low.
Disadvantage
 Difficulty could be faced in fault detection.
 For high number of user it is not suitable.
5

Mesh Topology- In this topology each device is connected to all other devices in the computer
network (Lecher, Platzer and Weiner, 2018). In this type of connection data and information
transfer can be performed between two devices.
Advantage
 Lo traffic faced during data transfer.
 More reliable then other topology that is used in the computer network.
 Fault detection and solution is easy.
Disadvantage
 More wire required in this topology.
 More I/O ports are required in this process.
