This document discusses various network topologies. It begins by defining a network and network design. It then explains that network topology plays a major role in a network's functionality. There are several common network topology categories including: bus, star, ring, mesh, tree, and hybrid. The bus topology connects all nodes to a single backbone cable. The star topology connects all nodes to a central hub. The ring topology connects all nodes in a closed loop with each node connected to two others. The mesh topology provides redundancy with each device connected to every other. The tree topology combines star and bus topologies with multiple star configurations connected by a backbone. A hybrid topology uses two or more different network topologies.

3. Network & Network Design
Network: A network consists of two or more computers that are linked in order to share resources
(such as printers and CDs), exchange files, or allow electronic communications. The computers
on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared
light beams.
Network Design (network topology ): is the physical and logical arrangement of nodes and
connections in a network. Nodes usually include devices such as switches, routers and software
with switch and router features.

4. network topology important
Network topology plays a major role in how a network functions. Namely, the topology has a
direct effect on network functionality. Choosing the right topology can help increase performance,
as a properly chosen and maintained network topology increases energy efficiency and data
transfer rates.

5. network design categories
The physical topology of a network is the physical layout of nodes and connections. Connections
include the lines in diagrams that connect nodes, such as Ethernet or Digital Subscriber Line
wires, fiber optics and microwaves
Logical network topologies define how a network is set up, including which nodes connect and
how, as well as the pattern of data transfers.

6. Bus network
In the bus topology, a common backbone is used to
connect every node in the network. The backbone is a
single cable that acts as the shared connection for all the
nodes attached into it via interface connectors.

7. Star network
The star topology has a single, central hub, to
which every node on the network is connected
to. Data being transmitted between the network
nodes has to pass through the central hub.

8. Ring network
All the nodes in a ring topology are connected
to each other in the form of a closed loop.
Every node on the network is only connected
to two other nodes. It is the cheapest network
topology to establish and provides high data
transfer rates

9. Mesh network
The devices in a mesh topology have redundant
data paths. Each device on the network has a
point-to-point connection with every other
device on the network

10. Tree network
The tree topology combines the
characteristics of star and bus topologies.
It includes multiple star configured
networks connected to a single backbone
cable.

11. Hybrid network
A hybrid topology is a type of network topology
that uses two or more differing
network topologies. These topologies can
include a mix of bus topology, mesh
topology, ring topology, star topology, and tree
topology.
