Topology The physical topology of a network refers to the configuration of cables, computers and other peripherals. The main types of network topologies are:

Linear Bus Star Ring Tree or Hybrid Linear Bus topology A linear bus topology consists of a main run of cable with a terminator at each end. All servers workstations and peripherals are connected to the linear cable

Star topology A star network is designed with each node (file server, workstation, peripheral) connected directly to a central network hub or server Ring topology

A ring network is one where all workstations and other devices are connected in a continuous loop. There is no central server Tree or hybrid topology

A tree or hybrid topology combines characteristics of linear bus and star and/or ring topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable Network Operating Software

Network operating systems coordinate the activities of multiple computers across a network The two major types of network OS are: Peer-to-peer

Client/server Peer to peer network OS In peer to peer network OS, there is no file server or central management source; all computers are considered equal Peer to peer networks are design

primarily for small to medium LANS AppleShare and Windows for Workgroups are examples of programs that can function as peer to peer Client/Server network OS Client/server network OS

centralise functions and applications in one or more dedicated file servers. The file server provides access to resources and provides security Novel Netware and Windows NT Server are examples of client/server network operating systems
