Familiarisation Q10 (4 marks): Load time (4 marks): official criteria and sample answer
Criteria
4: Explains how the load time of the web page can be improved. 3: Outlines how some issues affecting load time can be resolved. 2: Identifies issues affecting load time OR outlines how to resolve ONE. 1: Some relevant information.
Sample answer
The images can be resized to 640 x 480 beforehand so that the webpage does not need to load the large 4000 x 3000 images. The multiple CSS style sheets could be converted into a single .css file, reducing the number of HTTP requests the browser needs to send. If the "image-gallery.js" JavaScript file at the top of the source code loads slowly, it can be moved to the bottom just above
