BASIC NETWORK ARCHITECTURE TOPOLOGY
NETWORK TOPOLOGY
DEFINITION	THE LAYOUT OF THE COMPUTERS AND DEVICES IN A COMMUNICATION NETWORK
	TYPES OF NETWORK TOPOLOGY
BUS NETWORK	RING NETWORK	STAR NETWORK
PHYSICAL TOPOLOGY consist of a single central cable (backbone) to which all computer and other device connect	PHYSICAL TOPOLOGY all the computers and other devices on the network connect to central device(hub/switch) thus forming a star.	PHYSICAL TOPOLOGY a cable forms a closed loop with all computers and devices arranged along the ring
LOGICAL TOPOLOGY it transmit data, instructions and information (dii) as aseries of signal in both direction where all nodes receive the signal but only the intended recipient will accept and the rest will ignore.	LOGICAL TOPOLOGY dii transfer from one node to another node passes through hub/switch	LOGICAL TOPOLOGY data transmitted from devices to another decives around the entire ring, in one direction until it reach its destination using token
ADVANTAGES DISAVANTAGES -inexpensives and easy to install -if one device fails it does not affect the others -network will malfunction if the backbone is damaged -difficult to identify thee problem if network shut down	ADVANTAGES DISAVANTAGES -easy to troubleshoot -if one device fail, the others will not affected -network will be malfunction if the hub/switch break down -required more cable	ADVANTAGES DISAVANTAGES -cable faults are easy located -data packet are flowing in one direction at high speed -span larger distance but more diificult to install -network malfunction if the cable break down
