What is VLan?   What is Trunking?  What is Broadcast Storm?  What is the difference between Layer2 and Layer3 Swtiching hub?  What are equipment required for a simple SOHO usage? Do we need ADSL modem to use with ADSL service? Infosmart have some Routers, are they the one to use with ADSL? Why Infosmart using the term xDSL or DSL alone but not ADSL? What is difference? What is high-speed DSL, what is cable connection? Major difference between SOHO router and firewall router? When should I use firewall router? What is major difference between NFR3014 and NVR3015? When I (SOHO user) rent a ADSL service from ISP, what kind of connection cable they will mostly give to me (using same telephone cable, or a special kind of cable), what kind of connector using with that cable?   Any advise from you with technical view point for ADSL? What is the difference between NVR3015 and NFR3014, cause it seems both are VPN Router???
