4.2.2 Peer – to – Peer
It means that each device on the network can provide information to others and, at
the same time, request information from other devices connected to the network
(meaning that each device on the network acts as both a server and a client
simultaneously). No device stands out in terms of permissions and rights, although
their computing capabilities may vary. The size of this network may vary, ranging from
a small number of devices, such as file transfer between two devices via Bluetooth,
to very large networks for sharing files globally, like BitTorrent.

This type of network is considered suitable in the following cases:
• Data or files are already present or distributed on network devices.
• Network security is the responsibility of each device, with no specific server

device for user permissions.
Features of the Peer-to-Peer Network:
• One of the main features is the low cost of establishment since there is no need

for a specialized server device to provide the required service.
• Solves the problem of relying entirely on the server device (single point of failure)

due to the distribution of data and resources among devices.
Features of the Client-Server Network compared to Peer-to-Peer:
• Centralized data allows for backup according to a specific schedule.
• Easy access to information and resources due to their concentration on the main

devices in the network.
• The potential to achieve high levels of security and confidentiality in this type of

network.
