PHYSICAL TOPOLOGY : physical topology of a network refers to the configuration of cables, computers, and other peripheras
LOGICAL TOPOLOGY : logical topology of a network refers how signal travels along the physical path
COMPUTER NETWORK TERM :
NODE - any device that connected to the network
CLIENT - A node that requests and uses resources available from other nodes
SERVER - a nodes that share resources with other nodes
HOST/SERVER - any computer that provides sevices and connection to other computers on a network
SWITCH - A devices used to connect multiple devices on a single network; forward packets to only th intended recipient
HUB - the devices that provides a comman central connection point for nodes on network
TYPE OF NETWORK TOPOLOGY
- star topology
- bus topology
- ring topology
DEFINITION - on a ring network, a cable forms a closed loop(ring) with all computers and devices arranged along the ring
ADVANTAGE
1.All computer have equal access to the resources in the network
2.cheap to imstall and expand
DISADVANTAGE
1.Troubleshooting is difficult in ring topology
2.failure of one computer disturbing the whole network
DEFINITION - a bus network consists of a single central cable(backbone/trunk), to which all computers and other devices connected
ADVANTAGE
1.use a small network
2.failure of one device does not effect the network topology
DISADVANTAGE
1.the network will be malfunction if the single central cable breaks down
2.it is slower than ring topology
3.cable has limited lengthh
DEFINITION - all the computers and other devices on the network connect to a central devices(hub/switch), thus forming a star
ADVANTAGE
1.hub can be upgraded easily
2.easy to troubleshoot
3.if one device fail, it not affected the network
DISADVANTAGE
1.the network will mulfunction if the hub of switch break down
2.required more cable than most of the other topology
