High Speed Internet
DSL (Digital Subscriber Line) is a service offered by many ISPs. DSL is available in various access speeds. DSL is generally a minimum of 128Kbs upload speed. Internet access for multiple computers over a DSL connection is very affordable for home users and small businesses.
DSL installation by the ISP generally consists of the preparation of the phone line to the structure. Many ISPs provide a free modem and all equipment necessary except the hardware required by the computer. The computer must have a NIC (Network Interface Card) installed for either a LAN (Local Area Network) or specifically for the DSL. When a LAN is present, the DSL may be connected through a Router to a hub to provide access for up to 253 computers on the network.
Cable companies provide high speed internet access. However, before contracting for cable internet for a business, confirm that the provider allows business usage. Cable internet is comparable with DSL and the basic speeds are often higher. In a LAN, cable internet may be connected through a Router to provide internet access to the entire network.
One of the greatest expenses in configuring a network is cabling. Today, wireless technology allows existing networks to insert a wireless access point (WAP) or use a wireless router. Computers on the network then connect to the network through the WAP eliminating the cost of the wiring. In large networks or structures, some wiring may be necessary because of the limited range of the wireless devices. But the overall cost of a network can be greatly reduced. This also provides for easy relocation of a network.
Satellite companies are now providing high speed internet service. Satellite service can be configured for a network in a similar manner to DSL and Cable. Satellite is a good alternative in areas where DSL and Cable are not available.
