Essay / Research Paper Abstract
An advanced-level 9 page research paper on techniques, procedures, and standards for the successful establishment of a Layered Approach Network (L.A.N.) in business settings. The ISO's definition of seven layers of network structure are explained as are recommended tools, cable, and so on. Issues concerning the construction of the LAN are then described layer by layer. Bibliography lists 9 sources.

below it, and communication to adjacent levels is through a well-defined interface. This architecture allows one to design elements of the network without having to worry about unexpected interactions, incompatibilities
or inefficiencies. The idea of a layered architecture has been carried to a formal extreme in the International Standards Organizations (ISOs) definition of seven layers of network structure.
Since this particular business use if a fairly simple one, I shall refer to three layers, each of which represents several ISO layers. The three layers to be followed in
this particular design are as follows: Physical Layer. This refers to the physical medium through which signals are carried, be it copper wire, fiber optic cable or
wireless transmissions. Protocol Layer. This refers to protocols used to encapsulate information and present it to applications running on devices attached to the network. These protocols define
a set of rules that enable different entities on the network to communicate with each other. Application Layer. This refers to programs that run on computers attached
to the network and provide specific tools or services to users of the network. Physical Layer. Currently, computer applications that operate on LANs in the small business
environment can be handled with inexpensive copper wiring. Present technology allows for operation at speeds of 10 million bits per second, and it is possible to install wiring capable of
transmitting data at much higher speeds. A prudent recommendation is to use this type of wiring, known as Category 5. Twisted Pair wire. This choice combines economy of hardware and
ease of installation with a reasonable allowance for future expansion. The recommended cable for installation is Category 5. The cost difference between a Cat5 cable
