NComputing

NComputing is a way to create virtual desktops (sometimes called zero clients or thin clients) which enable multiple users to simultaneously share a single operating system instance without using much cpu.
NComputing, based in Santa Clara, CA is a privately held for-profit company with offices in the United States, Australia, Canada, China, Germany, India, Korea, Poland, Russia, Spain and the United Kingdom; and resellers around the world


The combination of NComputing hardware (access devices, thin clients, zero clients) and virtualization software (vSpace desktop virtualization software) use the excess computing capacity of one PC or server to create multiple virtual desktops.

The company offers a variety of product of ncomputing, one of the product of ncomputing was
 vSpace Client for Windows. that allows you to lower costs while adding new capabilities such as remote, mobile, and legacy PC access to NComputing vSpace deployments. Extend the value of our easy to use, but incredibly powerful vSpace Server desktop virtualization software to any Windows PC, laptop or netbook.
 
X-series access devices connect via CAT 5 cable to a PCI card that is installed in a shared PC. The technology supports up to two PCI cards. The maximum distance between the PC and an access device is 10 m (33 ft). The X-series comes in kits which include one PC card and several access terminals, depending on the specific product.

Unlike the X-series, the NComputing L-series does not use a PCI card. L-series access devices connect each user’s keyboard, mouse, other USB devices and monitor back to the shared PC over standard Ethernet cables through a router or switch. An entry-level server supports approximately 30 users. The L-series comes in kits that include NComputing’s vSpace software and one access device.


The U-series are the simplest of all to connect, because they connect into USB ports on the host computer, and thus no network switches or PCI cards are required. USB has an inherent distance limit.

operating system that support of ncomputing is Linux. this os supported through a version of vSpace Server for Linux software. Currently, NComputing offers support for Ubuntu <=12.04.1.

Windows is supported through a version of vSpace Server for Windows software. The supported versions of Windows include: Windows Server 2003 R2 SP2, Windows XP SP3 (32-bit); Windows Server 2008 SP2, Windows Vista SP21(32-bit); Windows Server 2008 R2 SP1, Windows MultiPoint Server 2011, Windows 7 SP1 (both 32- and 64-bit). The vSpace Server software and hardware clients require registration after 30 days for product upgrade notification
