Types Local Area Networks (LAN)

LANs are easy to understand when described into their physical components. The components are stratified into layers as defined by the Open System Interconnection (OSI Reference Model) where each other support a distinct functionality sets. A LAN result Accessement ideology describes in which Network attached resources are shared. These aspects of Network is referred to as its types

Common LAN Types are
a) Peer – To- Peer
b) Server Based

A LAN topology refers to its physical arrangement of communicating devices such as computers hubs, switches, routers etc on a wiring closet. The basic topology includes
a) Bus
b) Star
c) Ring

LAN Attached devices
The three most common primary devices are
a) Servers
b) Client
c) Resources ( Printer etc)

A Primary LAN device is one that can either directly access other devices or de access by other devices. A Server - is any LAN attached computer that host resources shared by other LANS attached devices. A Client is any computer that access resources stored on a server via a LAN. Printers are output devices that produce hard copies of files. CD ROMs, floppy drives and archives can all be shared via a LAN but they tend to be secondary resources i.e. they are connected to a primary devices. Subordination of a device to another device is known as Slaving e.g. CD-ROM drive to a server
