What is a Demo?

A “demo” (short for demonstration) is a multimedia presentation designed to show off both the graphical capabilities of the computer and prowess of the programmer. The Commodore Amiga was a popular platform for demo creators due to its advanced (for the time) and standardized hardware (as opposed to a PC, which comes shipped with many possible hardware configurations).

Most demos consist of various 3D (vector) graphics, 2D “blitter” displays and still art. The 3D graphics were typically rendered in the Amiga’s low-resolution mode (320×256 for European PAL; 320×200 for NTSC machines) while stills could be in high resolution mode or even high resolution interlaced (640×512 PAL; 640×400 NTSC).

What is Hotlinking?

Hotlinking (also known as inline linking, piggybacking, leeching and bandwidth theft) refers to when one site links directly to an object on a second site.

How Hotlinking can Affect your Wordpress Blog

Hotlinking not only allows another site to use your content without permission but also uses your bandwidth to do it. Every time a user surfs to the page of the offending site, the actual image shown is downloaded from your server to the user’s browser, even though the user is not on one of your web pages. This can degrade performance on your site or even cause your site to run over the bandwidth limit allotted by your web host - typically resulting in additional charges or even a suspension of service.
