No, the Pixel Shader version describes the capability of your hardware. If you're getting that error from a game you will probably need to upgrade your video card. There is a way though to use software emulation but its best if you have the actual hardware that uses pixel shader.
You cant buy pixel shader 1.1 as a standalone software/hardware, it is embeded into most of the new video cards that are out mostly geforce4 and higher .
Pixel shader is a standardized set of programming codes used to render more lifelike lighting in 3d applications and games. It is hard-coded into your computers video card and its drivers. Therefore it is actually both. There are programs out there which can emulate pixel shader purely through software, this solution often leads to poor performance and system instability. Pixel shader works best when it is natively supported by hardware. The best software about DVD video iPod zune iPhone iPad etc at http://www.dvdtoipodsoft.com
No, the pixel shader is built into the hardware
A VDU is hardware.
A scanner is both hardware and software, the device itself is hardware (all devices are hardware) but the driver(a program) that runs it is software.
hardware
A microphone is hardware. Software is what programs and games are called.
both a hardware and software
Motherboards are hardware components, not software.
Have to be hardware. How could you write software if there were no hardware to write it on?
Software. Short and sweet. Hardware needs software to work.
