Make the workgroup switch connection
On a shared 10-Mbps hub, each client computer gets only about 3 Mbps of bandwidth on average. If all ports are busy, the number drops because each client's network interface card is trying to get a free line through the hub. Contrast that congestion with that of a switched network. Each switch port receives dedicated bandwidth, similar to a dedicated phone line. A server that needs more bandwidth and handles high-priority traffic can connect directly to the

Organizer puts planning in motion
As business card holders and daybooks have evolved into personal information managers, Lotus Organizer is still a standout. Version 5.0 integrates the functions of its paper-based forebears with Internet calendaring and scheduling. It has matured without turning stodgy. The interface, based on the familiar day planner metaphor, is transparent to anyone who can page through a calendar, to-do list, directory or notepad. Organizer's call-scheduling component will dial phone numbers

This device lets you peek into your network's future
Box Score: A Every network administrator needs a crystal ball. Most practitioners of the black art of network management rely on software tools such as Hewlett-Packard Co.'s OpenView or IBM Corp.'s Tivoli/TME.

Get a grip on managing your network
Large networks can be as inscrutable as the Cheshire Cat. Understanding their connections takes plenty of infrastructure knowledge. Any administrator who wants to manage assets or find performance bottlenecks must have a map. The GCN Lab took a look at three tools, Visio Enterprise, Micrografx NetworkCharter Pro and netViz 4.0, for mapping devices connected to a network. Each takes a slightly different approach that fits specific purposes.

Can directories keep NOSes in sync?
A still-immature network operating system, NT Server does not have a directory structure and cannot scale up to enterprise levels as well as other NOSes can. Nor has Microsoft Corp. developed good ways of making NT work with other NOSes. But the competition has. Novell Inc. has delivered a second version of Novell Directory Services for NT—essentially acting twice as an organ donor.

Wireless presentation tools not ready for the stage
Ever since the days of the IBM PC Jr., many users have insisted on wireless input devices. The demand has increased with PC presentations because it is much more difficult to run a live presentation from a notebook computer than it is to switch slides or transparencies. Some wireless mice have gyroscopes to broadcast position information. This is cool, but use them in the midst of a presentation, and you might look like you are

Novell weighs in with hearty NetWare 5
How do you hide an 800-pound gorilla? Make it compete against Microsoft Corp. The joke pretty well sums up Novell Inc.'s situation. Once undisputed king of the LAN, Novell has been overshadowed by Microsoft in the network operating system market. Ironically, Novell only left the hardware business to develop NetWare because, at the time, IBM Corp. ruled the PC industry.

Latest version of NT blends the best of two OSes
Is Microsoft Windows NT Workstation 4.0 still the champ? Workstation 4.0 arrived as the most streamlined and reliable graphical operating system that Microsoft Corp. had ever turned out. After the GCN Lab's second examination of a beta version of NT Workstation 5.0, I've concluded that NT 4.0 may still be the most streamlined, though 5.0 does have greater stability.
