1. What connection does the company Compuserve have with gif's?
Compuserve introduced the GIF format in 1987 to provide a color image format for their file downloading areas, replacing their earlier data compression format. GIF became popular because the data compression algorithm it uses allows for the exact original data to be reconstructed from the compressed data.
2. Please explain image optimization for the Web.
Image optimization is ultimately a balancing act between file size and picture quality. Most of the load time for a webpage comes from the graphics and images used. In order to reduce the size of the image files there are several factors you can control. These key factors are bit depth, resolution, and dimension.
3. How does screen resolution affect a website?
If your site is designed to look appropriate at a high resolution, the average small resolution user visiting the site is going to see a page that looks as though the layout has not been considered. Not only will the site’s image not come across as intended, but the visitor will have to scroll from left to right in order to view all of the page’s content. The catch is that if you design a website to look good on a small screen with a small resolution, it’s going to look really tiny to users with big screens and high resolutions.
4. What does it mean to be Section 508 compliant?
Section 508 compliance is a requirement that federal agencies’ electronic and information technology is accessible to people with disabilities. For example, to make images accessible to the blind, this means providing an alt tag on all of the website’s images that describes the content featured in each image.
