Tree Topology
In this topology, nodes are connected as branches of a
tree where hub acts as a root node. It is very simple in
nature as it is easier to add or remove the faulty nodes.
But its major disadvantage is that if the root node fails to
operate, the entire network is inoperable.
Tree Topology
Mesh Topology
In this topology, every single node in a network is connected to
all the other nodes or computers in the network. There is minimal
chances of breakdown in this topology. This topology is mostly
used in LANs.
NETWORK ARCHITECTURE
Mesh Topology
The network architecture defines the overall design of the computer
network. There are two types of network architectures.
Peer-to-Peer Network
It is a network of two or more computers that uses the same
type of program to share the data. Each computer is considered
to have equal responsibility and acts as a server to the other
computers in the network. It works well in small environment.
Peer-to-Peer Network
Client-Server Network
Internet It is a network in which one computer is designated as the
Clients
server and all the other computers connected on the network
are called the clients. The clients can request for the services
Client-Server Network from the server. This is called the client-server network.
WIRELESS NETWORKING TECHNOLOGY
In a wireless networking technology, no wires or physical media is used for connecting computers.
It uses electromagnetic waves like infrared, microwaves and radio waves for transmission of the
data. The choice of technology depends on the distance and speed of transmission. There are
two types of wireless technologies named Wi-Fi and Bluetooth.
Wi-Fi
Wi–Fi is the most popular wireless communication technology used for homes,
private business LANs and public hotspots. A Wi-Fi enabled device such as a
PC, video game console, mobile phones or MP3 player can connect to the
Internet when it comes within the range of a wireless network. Wi-Fi allows us
Wi-Fi
to deploy local area networks without wires thus reducing the cost of network
expansion.
