3.  Network Topology is the arrangement of the
various links, nodes, etc. of a computer network.
Essentially, it is the structure of a network and many
may be depicted physical topology is the placement
including device location and cable installation, while
logical topology illustrates how data flows within a
network regardless of its physical design. Distance
between nodes, physical interconnections,
transmission rates or single types may differ between
two networks yet their topologies may be identified.
What is Topology?

4. There are 7 types of topologies:
Bus Topology
Ring Topology
Token Ring Topology
Star Topology
Mesh Topology
Line Topology
Tree Topology
Types of Topologies

5.  A Bus Topology is a network topology in which nodes
are directly connected to a common linear (or
branched) link called a bus.
Bus Topology

6.  A ring network is a network topology in which each
node connects to exactly two other nodes, forming a
single continuous pathway for signals through each
node - a ring. Data travels from node to node, with
each node along the way handling every packet.
Ring Topology

7.  A type of computer network in which all the
computers are arranged (schematically) in a circle. A
token, which is a special bit pattern, travels around
the circle. To send a message, a computer catches the
token, attaches a message to it, and then lets it
continue to travel around the network.
Token Ring Topology

8.  A star topology is a topology for a Local Area
Network (LAN) in which all nodes are individually
connected to a central connection point, like a hub or
a switch. A star takes more cable than e.g. a bus, but
the benefit is that if a cable fails, only one node will be
brought down.
Star Topology

9.  A mesh network is a network topology in which each
node relays data for the network. All mesh nodes
cooperate in the distribution of data in the network.
It can be applied to both wired and wireless
networks.
Mesh Topology

10.  In topology, the long line (or Alexandroff line) is
a topological space somewhat similar to the real line,
but in a certain way "longer". It behaves locally just
like the real line, but has different large-scale
properties (e.g. it is neither Lindelöf nor separable).
Line Topology

11.  A tree topology combines characteristics of linear bus
and star topologies. It consists of groups of star-
configured workstations connected to a linear bus
backbone cable. Tree topologies allow for the
expansion of an existing network, and enable schools
to configure a network to meet their needs.
