Networking gadgets is an information technology company that provide the
networking services to their consumers and currently, total 8 employees are working in
this organization. In future, they will hire 10 more individuals to improve their
productivity for which they can adopt the server-based network to control and manage
their works. It is one of the best approaches to manage and backup their project files
because they provide the accessibility to those employees that are working on a project
(Akyildiz, Lee, Wang, Luo, & Chou, 2016). It has the potential to enhance the security
and privacy of their data or information files and it also provides the central control
process which is the very best approach to share files rather than storing them on every
machine. A recent study observed that to control and manage the 15 employees by
peer-to peer network is more difficult as compared to server based network and many
largest business industries are using this technique in their computer networks.
Therefore, networking gadgets should adopt server based network to reduce the
complexity and handle employee’s details for project files (Ozdemir, & Xiao, 2009). In
last two years, the rate of server based network has increased by 44% because of their
several benefits like very easy to design and implement, low power consumption; more
secure rather than peer to peer networks and improve the performance of
communication system (Peterson, & Davie, 2007).

To increase the data speed of a network which is connected with the 50
computers the combination of routers and switches can be used because both have
potential to enhance the internet speed by 56 Mbps. The main server and one computer
system are connected with the router to control and manage the data speed between
these computer devices (Akyildiz, Wang, & Lin, 2015). The router is a type of
networking system which transfers data packets between the computer networks and
routes the traffic signals from one network to another. One router is sufficient to handle
the internet speed between 50 computers and it is interconnected with two more data
lines. Two 24 port network switches can be used to connect two more devices with each
other and it transfers data at the data link layer of the OSI model. The management team
should design and implement a central server which can control and manage the
incoming or outgoing transmissions. Moreover, the networks hubs can be upgraded to
handle the 1000 Mb per second data speed and company should adopt the security tools
to avoid bugs and traffic signals from networks like firewall, encryption and so on. The
recent investigation identified that the router is the very common network which is
used by many companies to enhance the internet speed and connect numbers of the
computer system at a time.

To reduce the impacts of the broadcast traffic signals within the local area
network (LAN) an extended star topology can be used because it has the ability to
control and manage the traffic between switches. People can adopt and install the NIC
card system which converts the data packets into numbers of frames by which they only
travel to the set destination. The start network topology is the arrangement of elements
like links, nodes and hubs of a computer network and many companies are using this
technique to handle the issue of traffic during data communication. It is analysed that
this topology interconnects the nodes with the central connection point and uses
numbers of data cables like a bus. If anyone cable fails then only one node will be
brought down and rest of the network will work properly. With the help of this
approach, people can split their servers into one or more workstation subnets and the
issue of traffic can be routed.

In this situation, the old tech corporation company is running inefficiently and
the main business is facing as a result of their use of obsolete network techniques. With
the help of some planning and meticulous execution, such kind of issues can be resolved
and management team will require main three network devices to increase the overall
efficiency such as 18-port gigabit switch, advanced routers and wireless cisco system.
The workstations will be connected to these switches with the help of twisted pair
cables and sub-networks and the modern switch will enable the office system to make
use of the complete network bandwidth. According to the given scenario, the old tech
