Java: Java and JavaScript are programming languages used to write software applications that can run inside a web browser. They're used to create very complex webpages that change in response to people's input. Confusingly, Java and JavaScript are not actually related (aside from the fact that they're both used to write computer programs that run inside a web browser...). It's named after Java coffee, consumed in large quantities by the language's creators (and, indeed, programmers everywhere).
JPEG: A commonly used method of compressing digital images with very little loss of image quality. ‘Raw’ images are enormous, and people would quickly run out of storage space without image compression. JPEG is an acronym that stands for the Joint Photographic Experts Group, which created the standard.
