Zipping

Finally, we come to the last letter of the alphabet and what other choice would fit into this section except zipping (or file compression). The ability to reduce bandwidth consumption has many benefits, including reduced data transfer costs, faster page loads for the visitor and, when combined with caching, reductions in HTTP requests.

Caching is another useful method of reducing the amount of bandwidth used.

Knowing how to optimize your content and code is one thing, but being able to squeeze every last unnecessary byte from your images and knowing how to carefully balance the quality and file weight is critical as well. Learning to optimize website assets is an essential skill which no budding web designer wants to be without.

A zipper, zip, fly, or zip fastener, formerly known as a clasp locker, is a commonly used device for binding the edges of an opening of fabric or other flexible material, such as on a garment or a bag. It is used in clothing (e.g., jackets and jeans), luggage and other bags, sporting goods, camping gear (e.g. tents and sleeping bags), and other items. Zippers come in all different sizes, shapes, and colors. Whitcomb L. Judson, who was an American inventor from Chicago, is sometimes given credit as the inventor of the zipper, but his device was used for footwear, not clothing. The method, still in use today, is based on interlocking teeth. Initially, it was titled the "hookless fastener" and was later redesigned to become more reliable.
