Without getting too technical, a cache is a collection of temporarily stored data for quick access upon request. When it is requested, a computer needs to run several processes before the information can be presented. Caching solves this issue by processing the frequently requested information and then storing it in temporary storage or memory. This allows computers to access it the file quickly. These caching plugins will do all of the technical work for you behind the scenes to speed up the delivery of your content to your visitors.
