• No. We don’t compete against PCs; we complement and augment their power. We are expanding the number of individual seats for users that have limited access to computing capabilities. Here are some examples of where we are expanding markets:
Emerging economies
Businesses: Many are forced to limit their computer use to a few key employees due to capital and support costs. With NComputing, they can expand access to a greater number of employees and therefore improve productivity.
Schools: Rarely do schools have a student-to-computer ratio that supports effective learning. Many schools today are adding virtual desktops to existing PCs and getting up to six new users on an existing PC or deploying new PCs with additional access devices.
Libraries: Most do not provide computing resources for productivity or web surfi ng. Those that do rarely have enough to serve their customers, and maintenance of unreliable PCs can be extremely burdensome. With NComputing’s virtual desktops 3, 10 or up to 30 more users can be supported from a single shared PC.
Internet cafés: For email, web surfing and more.
Developed regions
Student access: Even in wealthy countries, school funding lags and rarely supports one-to-one computing. With our solution, schools can get at least twice the number of seats for the same budget. For the US student population, which has 3.8 students per PC, this solution can provide more students individual access to computing.
Expanded reach: A PC is generally fi xed to a single location; what if you are in another room and just want to do a quick web search? NComputing can provide simple and inexpensive access for another room that provides exactly the same data as
your shared PC.
Manufacturing: No moving parts means a robust and durable design that survives extremely harsh coditions.
• The are many, but the four largest are:
Lower computing cost per individual user. As low as $70 per seat.
With fewer PCs to maintain, support headaches and costs are greatly reduced.
Our access terminals use less than 5 watts of power. This is generally only 5% of the power of a typical PC.
All of the NComputing software and hardware products are designed to be easy to set up, secure, and maintain by anyone with basic PC skills.

• The appeal of desktop virtualization is that many users can access the same computing resources at the same time. The model used to be one user per PC; it is now four or seven or even up to thirty 30 users or more per single PC or server.
• With a simple installation, NComputing virtualization software and access devices, along with a mouse, keyboard, speakers and monitor, supply another individual session or user account.
• The shared PC provides the computing resources, the operating system, and access to an internet or intranet connection. NComputing access devices connect to the shared PC and provide individual sessions to each user.
• NComputing’s desktop virtualization technology delivers a rich PC experience that is usually identical to using a dedicated PC. However, there are some times where people need their own PCs:
CD-ROM/DVD: The CD-ROM is shared by all users and cannot stream different fi les to all users at the same time. However, a similar one-on-one experience can be achieved by downloading the fi le from the CD to the hard drive and then streaming the
data, or if no one else is using the CD, then one access device can stream directly from the CD.
3D acceleration: NComputing does not provide 3D acceleration support for applications such as 3D games. Most applications support Microsoft’s terminal services API and work well in a virtual environment, but some applications may not work. Check your application suite for multi-user support.
Power users: usually need a dedicated late-model PC to run applications that need the majority of the processor’s bandwidth. This type of computing is not advised for a virtual environment.
USB: Our port (certain models) is designed for supporting USB memory devices only.
• The typical processor utilization for a productivity application (like Microsoft Office) is only about 1-10% of the processor’s bandwidth. Therefore, if the users are typing a report, entering data into a spreadsheet, or preparing a presentation, the number that can be supported is up to 30 users.
• Today’s PCs have dual-core processors that run up to 3GHz and deliver more than ten times the computing power of a typical PC from just 5 or 6 years ago. That is plenty of processing power for users in a virtual environment.
• One way to think of this is as the local power grid. Many people draw power from it for their use; some will be using it just for lighting, while others will be running their clothes washer and dryer and still others have industrial needs. The NComputing environment is similar to a grid where everyone shares the processor resources; but the great thing about PCs is that the processors are extremely fast and peak requirements are generally measured in milliseconds or at most seconds, not the cycle time of a dryer. Therefore, if the power needs to hit 100%, it is likely for a very short period of time. These periods may be so short that a person typing a report could experience >100% processor needs from others in the shared environment, but never even notice it.
• If more processing power is consistently needed, then tuning can solve the issue. The environment can be reconfi gured to allow more power for all applications by upgrading the host or reducing the number of users per shared PC.
• Typical web browsing also takes little processor bandwidth, and the majority of the time it also takes little networking bandwidth.
• Some applications demand huge performance capability such as 3D games, desktop publishing, full screen video streaming, and full-time CAD (computer aided design). Power users are accustomed to having their own PCs and should keep them.
• But this doesn’t mean that performance can’t be supplied to other users. For example, if someone is manipulating image fi les and needs some extra performance, there is available bandwidth. Even if this activity takes 80% of the processor’s capabilities, there are still resources available to the other users, and most of these “peak performance requirements” last a very short period of time so that overall performance is restored quickly.
