Network topologies 7
Network topologies determine how devices are physically connected in a network. There are several common topology types: - Bus topology connects all devices to a single backbone cable. A break in the cable disrupts the entire network. - Ring topology connects each device directly to its neighbors in a circular configuration. A break disrupts connections until the break is repaired. - Star topology connects all devices to a central hub or switch. Failure of the hub stops the entire network until repaired. - Hierarchical/tree topology allows expansion by connecting devices in a branching structure with control points. - Mesh topology fully connects each device to every other device for continuous communication if any connection fails.

- 2. Topology It refers to the arrangement or physical layout of computer cables and other components on the network. It can also be called the physical layout, design, diagram, or map of the network. Choosing a type is a very important for it will draw a great impact in the type of equipment to be used in the network, in the capabilities of the equipment, in network growth and management.

- 5. Bus Topology Single backbone • All hosts directly connected to backbone • Each end of the bus must be properly terminated with a resistor or a terminator. • Data passes back and forth to cable until it reaches the receiving station.

- 11. Hierarchical/Tree Topology Like the extended star except a computer controls traffic—not a hub or a switch. Allows for expansion of an existing network.
- 12. Mesh Topology Each host has its own connection to every other host Used in situations where communication must not be interrupted.
