WHAT IS A TOPOLOGY ?
▸ In computer networking, topology refers to the layout of connected devices.
▸ Network topologies describe the ways in which the elements of a network are
mapped. They describe the physical and logical arrangement of the network nodes. ▸ Topology can also be defined as the geometrically interconnection pattern by which the stations are connected using suitable transmission media.

CATEGORIES OF NETWORK
TOPOLOGIES
▸ Physical Topology : The physical topology of a network refers to the configuration of cables, computers, and other peripherals
▸ Logical Topology : The logical topology shows how data flows within a network, regardless of its physical design.

▸ All the nodes (file server, workstations, and
▸
▸
peripherals) on a bus topology are connected by one single cable.
A bus topology consists of a main run of cable with a terminator at each end. All nodes (file server, workstations, and peripherals) are connected to the linear cable. Popular on LANs because they are inexpensive and easy to install.

BUS TOPOLOGY
BENEFITS
DRAWBACKS
• It is Cheap, easy to handle and implement.
• Require less cable
• It is best suited for small networks. • The cable length is limited.
This limits the number of stations that can be connected. • This network topology can perform well only for a limited number of nodes.
