    They mean the same thing but up scaling is the more common term. It is taking a resolution and interpolating it to create a bigger resolution (like with resizing a photo) which is usually 720p or 1080i/1080p. A TV will also upscale itself to match the resolution of the panel inside.

    It is possible to upscale video with computer. But the scaling is usually done by the software, unless you get a driver, which allows your graphics card to do the scaling and de-interlacing. You should get the NVIDIA Purevideo Decoder, which is a high-quality decoder with video and audio features. However, the decoder applies only for MPEG2 video (DVD) and high-def material. So DIVX and XVID movies are still scaled by the software.

    For connecting your PC to your TV, you need to buy just a regular DVI-HDMI cable.

    Actually upconverting and upscaling are completely different.
    Upscaling is as described above.

    Up-conversion is the process that changes the way the video is transferred from one device to another.

    e.g. you could connect your Sky box to an amplifier using an S-Video connector, and the amplifier might be able to 'up-convert' this signal to higher quality component video output.
    In this process the resolution of the picture does not change.

    If you google upconverting, plenty of manufacturers use ther term upconverting instead of upscaling.

    Yes, it can be very confusing and even misleading.
    Their marketing guys sure make it difficult for people to get a handle on what they're paying for.
