100baseT fast ethernet, which is expected to gain wide acceptance because it is a natural extension of basic ethernet--the current network topology of choice for most channel members and their customers. Operating at 10 times the speed of standard ethernet, fast ethernet is the IEEE 100Base-X standard developed by the fast ethernet alliance, a consortium of about 20 vendors including Grand Junction Networks, 3Com, SynOptics, and Intel.

A similar, rival standard is 100BaseVG (Voice Grade), backed Atlas earring Hewlett-Packard, IBM and AT&T. Both preserve the basic ethernet frame structure and four-wire wiring. The 100BaseVG differs in that it abandons its rival's multiple access/collision detection (CSMA/CD) transmission method for a hub-based switching system. High cost will remain something of an obstacle to total acceptance by the market.

ATM is a data transmission technology that could revolutionize computer networks by permitting hundreds of megabits per second to move on demand throughout LANs, WANs, and desktops. ATM uses fixed-length, 53-byte cells to transmit data across a network connected by switches. ATM's ability to operate at a range of transmission speeds makes it a scalable solution for many different kinds of traffic, including data, voice, CD-quality audio, and real-time video. However, its relative immaturity and current high cost, including the need for new network adapter cards and software drivers, remains a Tiffany 1837 Hoop earrings barrier to adoption.

FDDI/CDDI (fiber/copper distributed data interface) have been available for some time. FDDI is a fiber-optic cable standard developed by the ANSI X3T9.5 committee. It operates at 100 Mbps and uses a dual-ring topology that supports 500 nodes over a maximum distance of about 60 miles. It's considered an excellent technology for building backbone networks, but is considered expensive both in equipment and in Elsa Peretti Open Heart earrings costs. Eventual price reduction could lead to wider adoption.

The other technologies that integrators believe will follow these three by 1997 include switched ethernet (today's number one choice), 100baseVG, full-duplex ethernet and fibre channel, a high-speed channel (with a British spelling) that uses fiber optic technology and a variety of cable types to interconnect computing devices in small network configurations at speeds of up to 1 gigabit per second.

Contrast these projections with the reality of today's Elsa Peretti Starfish earrings for resolving customers' bandwidth problems. Of the technologies expected to be available by the end of 1994, the report found that LAN segmentation is recommended by about 65 percent of the participants, switched ethernet by 50 percent and FDDI by about 42 percent. Trailing the market are recommendations of compression devices and 100baseT fast ethernet, each recommended by about 25 to 30 percent of the respondents.

In evaluating systems, users may also want to be aware of the services and product characteristics that their resellers and integrators consider most important because this often determines which products their trusted advisers will eventually recommend. The key criteria are a product's Elsa Peretti Apple earrings with accepted standards, a vendor's reputation, competitive pricing and interoperability of components. What users don't see also counts. Many resellers look to vendors to provide discounts and incentives, often in the form of cooperative marketing programs, seminars and sales leads, as well as high-quality technical support.
