Hubba Hubba

Mom always said it's nice to share, but with computer files it's critical. Luckily, prices for network hardware--mainly "hubs," the central junctions that let computers share information--are falling. In May, LinkSys Group became the first to break the $100 barrier for hubs with its high-performance EtherFast line: ten times the speed for 20% less than earlier models. A slower LinkSys model is under $45. Most major hub makers such as IBM and 3Com offer easy network-building kits, which include a hub--the chief expense--plus cables, connectors, and more, all guaranteed to work together.
