Computer Networks
Network Topology
Bus Topology
Bus patterns work best with a limitednumber of nodes. If more than a few dozencomputers are added to a network bus,performance problems may result. Inaddition, if the backbone cable fails, theentire network effectively goes down.
Mesh Topology
All the network nodes areindividually connected to most of theother nodes. There is not a conceptof a central switch, hub or computerwhich acts as a central point ofcommunication to pass on themessages.
Ring Topology
All messages/data packetstravel through a ring in the samedirection (either "clockwise" or"counterclockwise") from onenetwork device to the next andfeatures a closed loop. A failurein any cable or device breaks theloop and can take down theentire network.
Hybrid Topology
Hybrid refers to integrating two or more different Hybrid topologies. Star-Ringand Star-Bus networks are most common examples of hybrid network.While this topology has positives such as reliability and effectiveness, itis costly and complex in design and infrastructure.
Star Topology
A failure in any star patterned LAN will only take down one computer'snetwork access and not the entire LAN.

Types of Network
Internet
It is a worldwide/global system ofinterconnected computer networks. It usesthe standard Internet Protocol (TCP/IP).
Intranet
Implementation of Internet technologies within an organization rather than for external connection tothe global Internet.
Extranet
Extranet is a web portal that is accessible by an organization and its external vendors, partners, customers, or any other users that require access to restricted information.
Network Design
A server is a computer (node) that is a A servercentral storage unit for the network. Thiscan be a computer or a dedicated serverlike the one in our image.
