the access, distribution, and core layers
access, distibution and core
From a network design standpoint: Core Distribution Access
Don't cheat!
SSID
A hierarchical network design includes the following three layers:The backbone (core) layer that provides optimal transport between sitesThe distribution layer that provides policy-based connectivityThe local-access layer that provides workgroup/user access to the networkhttp://docwiki.cisco.com/wiki/Internetwork_Design_Guide_--_Internetworking_Design_Basics#Function_of_the_Access_Layer

Hierarchical data model :Advantages- simplicity- data security- data integrity- efficiency- ease to add and delete recordDisadvantages- implement complexity- database management problem- lack of structural independence- programming complexity- implementation limitation- procedural access languageNetwork data model :Advantages- easy to access data- can handle more relationship types- data independence- data integrity- data independenceDisadvantages- system complexity- lack of structural independence- procedural access language
Hierarchical Sequential Access Method-is a method to use sequential access of database.
reduced contentio for bandwidth, reduced size of physical layout, siplification of management More Secure because access layer switches can be configured with various port security options that allows the devices to connect the network.
if your talking about the disk to setup the online feature in PS2, you do not need it , some game's (if not all) have a feature in the online options that allow you to set up your online setting's,
