The importance of using computer networks in campus laboratories has increased
in improving the quality of education and research. Students and lecturers can share
information, work together, and access a wider range of resources through computer
networks. However, there are several issues in the use of computer networks in campus
laboratories, including low data transmission speeds, lack of network security, and limited
access to resources. In this study, several factors that affect the performance of computer
networks in campus laboratories will be tested, such as data transmission speed, and
others.
In a peer-to-peer network, any computer connected to the network can act as either
a workstation or a server. Meanwhile, in the ClientServer network, only one computer
serves as a server and another computer acts as a workstation (Widiyaningrum &
Awalludin, 2024). A communication network is a resource that can be used
simultaneously (shared) by several end users to communicate with other users who are
located far away. Not all users use the network at the same time, therefore it is logical
that these very important network resources are used together (Candra Laili, 2023).
LAN Computer Network or Local Area Network is a computer network consisting
of several computers that are interconnected in a relatively small area such as buildings,
campuses, or offices. LANs allow these computers to communicate and share resources
efficiently. This network is usually used by companies or institutions that need access to
data and information quickly and easily (Aswar, Alfin, 2024). We often find that the
quality of the network decreases over time, this is usually caused by the increasing
number of LAN network users and is exacerbated by the lack of increased bandwidth
(Baso, Hanifa A, Putri Azzahra, & Mukhtar, 2023).
WLAN or Wireless LAN is a computer network that uses radio frequency as its
transmission medium, where the access point uses frequency radio ao media connected
to the user as a configuration of the WLAN network (Reivaldi Kesuma Kagi,
Muchammad Ficky Duskarnaen, & Hamidillah Ajie, 2020). As a wireless network that
uses electromagnetic wave frequencies, the WLAN entry point is the basis in the
transmitter of electromagnetic waves from two directions which works on the bandwidth
of 2.4 GHz or 5 GHz (Saputra, Saryoko, Maulidah, Hidayati, & Dalis, 2023).
The initial concept of computer networks is the communication of data from one
computer to another. For the first time, data communication between computers is only
point-to-point, so there are only two computers that will be connected. After a long period
of development, the concept was developed so that the exchange of data at that time was
an exchange between 2 computers turned into a computer network. The concept of
computer networks is different from the concept of ordinary data communication, where
several computers will be connected by cables so that each computer can exchange data
with each other (M.Kom & Khairina, 2019).
The purpose of a computer network is to achieve its goal, every part of the computer
network can request and provide services. The party that requests/receives services is
