Analysts contend that if the cost of computing were to drop significantly, another one billion users around the world would join the information economy.
Using the latest computing technology in performing different chores is necessary as notes Ms Ebby Kosgei, a sales administrator at Smoothtel. She says it makes work easier, improves on quality delivery and saves time.
A centrally managed solution has now been developed that would be easy to use and maintain by all staff.
The NComputing solution is based on a simple fact: today’s PCs are so powerful that only a small fraction of their computing capacity is required for the vast majority of applications.
"NComputing taps the unused capacity by enabling up to 30 simultaneous users to run their own applications from a shared PC at a cost of as low as $70 per additional user," she says. Technology comes at a cost. For companies that use a large number of machines, scarcity of resources may make it impossible to maintain all the machines all at once even for a minor hitch.
The maintenance costs may be driven even higher depending on the individual computer consumption of electricity. In key organisations, for instance hospitals, surgical and operation units rely on computing. A simple technical problem like fan failure would require expensive and time-consuming maintenance and more importantly, long downtime while the PCs are being fixed.
How it works
Each user’s monitor, keyboard and peripherals connect to a small NComputing access device (virtual PC) that then connects to the shared PC. The virtual PC is inexpensive and highly reliable because it has no CPU, memory or moving parts.
NComputing virtualisation software shares the overabundant processing power of the PC and transmits the signals between the virtual PC and the shared PC. The solution is easy to deploy and maintain.
NComputing systems are compatible with Windows, Linux and standard PC applications. As a major leap forward in green computing, NComputing virtual PCs draw from one to five watts of power for each user versus 115 watts for a typical PC—a 90 per cent reduction in energy consumption.
Customers tend to need either flexible long-distance networking, or high-end multimedia performance. NComputing offers products tuned to each market. The L-series uses standard Ethernet networking infrastructure, such as routers, switches and wide-area networks (so that users can be located many miles away from the PC) to connect to the shared PC.
The X-series is ideal for workgroup clusters; it requires the users to be within 30 feet of the PC, but delivers the ultimate multimedia experience.
"The X300 Access Terminal Kit can help educators cut computing costs by allowing them to share one shared PC with three additional users, or up to seven users with two kits.

computer capacity
The kit’s PCI card, access terminals, and software harness excess computing capacity.
"The kit connects users directly to the shared PC via standard cable, includes terminal services software for Windows and Linux and supports standard applications, including multimedia" she explains adding that each user has a standard monitor, keyboard, mouse and speakers.
The L-series uses standard Ethernet infrastructure and has effectively no distance limitations. A standard PC can support 10 users with a desktop operating system OS, 30 with a server OS, and hundreds with a virtualised server. The L-series delivers web multimedia and costs about $200 per user.
The X-series provides ultimate multimedia performance. It uses direct-connect cables (up to 10 meters long) between the shared PC and the users.
An X-series kit includes a PCI card that installs into a slot in the shared PC and 3 or 5 access devices (depending on the model). With two kits in one PC, you get up to 11 users on one PC. X-series kits costs about US$70 per user. The vSpace virtualisation software is included.
