Abstract.
In today's interconnected world, a robust and efficient office network is crucial
for the smooth functioning of businesses. Whether it's sharing files, accessing the internet, or
communicating with colleagues, a well-designed network infrastructure forms the backbone of
modern workplaces. Cisco Packet Tracer, a simulation tool, provides an excellent platform to
learn about network devices and their principles by designing and implementing an office network
virtually.

Introduction
Currently, a new stage of development associated with fundamental changes in the field of
telecommunications is being implemented around the world. Issues of innovative development
have always been an urgent task for the field of telecommunications, which requires deep
knowledge. At the same time, innovative development in the field, considering the achievements
of developed countries, and the and the training of specialists are important. Implementation of
innovative development in the telecommunications sector requires a systematic approach, that is,
the provision of legal, technological, organizational, and qualified personnel. In modern
conditions, a complex approach aimed at solving the issues of innovative development in the
telecommunications sector requires knowledgeable and experienced specialists. The transition to
innovative development of the industry forces new approaches to the training of specialists.
For the innovative development of the telecommunications network, it is necessary to train
many specialists in network technologies, network solutions, and network integrators.

A network is a set of computers, terminals, and other devices interconnected by
communication channels that provide information exchange. Such networks that provide data
exchange between computers are called computer networks. It became possible to transmit
information over long distances through the network. The network provides opportunities to
transfer information, organize the joint operation of computers that are used separately, and solve
a problem with the help of several computers. In addition, it is possible to specialize each computer
to perform a certain task and to use the resources (data, memory) of computers together, as well
as to connect to the Internet network, which unites the computers of the whole world.
Examples of modern networks include local and global computer networks, corporate
networks, telecommunication networks, networks of communication operators, and the network
consisting of these networks, i.e., the Internet. Even though these networks are different, it is
possible to point out that they have many similarities. One of them and the most important is the
similarity of their structure, that is, their architecture.
In computer networks, as terminal equipment of users (computers), in telephone networks
(telephones), in television or radio networks (televisions or radio receivers),. Terminal equipment
of users can be connected to networks located outside of the telecommunications network.
Computers can be connected to local computer networks, and telephones can be connected
to a telephone switchboard (PBX, or Private Branch Exchange) in the office.
Cisco Packet Tracer is a comprehensive network training and learning program that
provides a unique combination of realistic simulation and visualization, assessment and exercise
creation, competition, and collaboration in a multi-user environment. Packet Tracer's innovative
features help students and teachers interact, solve problems, and learn concepts in a fun, dynamic
social environment.

Research results
Figure 2. Application window
This research employs a mixed-methods approach, combining quantitative analysis of
learning outcomes with qualitative assessment of student engagement and perceptions.
Participants engage in structured activities within Cisco Packet Tracer, including designing and
configuring an office network, troubleshooting network issues, and completing guided exercises.
Network devices serve various purposes in an office network, each playing a specific role
in facilitating communication and data transfer. Here are some essential devices commonly found
in office networks:
Switches
: Acting as the traffic cops of the network, switches connect multiple devices
within a local area network (LAN) and facilitate the transfer of data between them. They operate
at Layer 2 (Data Link Layer) of the OSI model, using MAC addresses to forward data to the
appropriate destination.
Routers
: Routers operate at Layer 3 (Network Layer) of the OSI model and are responsible
for directing data packets between different networks. They use IP addresses to determine the best
path for data to travel, making routing decisions based on network topology and routing protocols.

Access Points (APs):
In modern office environments, wireless connectivity is often a
necessity. Access points provide wireless access to the network, allowing devices such as laptops,
smartphones, and tablets to connect without the need for physical cables.
Cisco Packet Tracer provides a simulated environment for designing, configuring, and
troubleshooting network setups. Through the device's command-line interface (CLI) or graphical
user interface (GUI), users can configure various parameters, such as IP addresses, VLANs, and
security settings.
