Client/Server Network
In a Client/Server network, clients access resources from a central server. The server is responsible
for managing all the resources such as files, directories, printers, etc.

NETWORK TOPOLOGIES

Network topology describes the physical or logical layout of the network, that is, how all the
components (such as computers, cables and switches) are interconnected. Common network
topologies include:

Bus topology: In this topology, all devices are
connected to a single central cable called the
bus. Data travels in both directions along the
bus, but only one device can send data at a time.
It is less secure and not very robust - if the main
cable fails, the entire network stops working. Bus
topology is suitable for small networks that need
low speed and have a limited budget because
they are inexpensive to set up.

Star topology: In this topology, all devices are connected
to a central hub or switch, which manages data
transmission. It is a robust topology because if one
connection fails, only that device is affected. Fault
detection and isolation are easy in this setup. However,
if the central node fails, the entire network stop working.

Ring topology: In this topology, each device is connected to two
other devices, forming a circular pathway for data transmission.
It allows high-speed data transfer and is inexpensive to install,
but the failure of a single node in the network can cause the
entire network to stop working. Troubleshooting is difficult, ans
is considered a less secure topology.
