Final answer:
Web pages can open without an Internet connection if they are stored in the cache memory of the device. This allows quick access to previously visited web pages.
Step-by-step explanation:
When Jose clicked on the link to open a previously visited webpage on his tablet, the page opened without an Internet connection because the webpage was stored in the cache memory of his tablet. The cache is a temporary storage area that stores copies of web pages that Jose has recently visited so that they can be accessed quickly and easily without having to download them again from the Internet.
When Jose surfed the web a few days ago, his tablet automatically saved a copy of the web pages he visited in its cache memory. This is done to improve the browsing experience by allowing quick access to frequently visited web pages. So when Jose clicked on the link to open a previously visited page, his tablet was able to retrieve the page from the cache memory and display it, even without an Internet connection.
It's important to note that the cache memory has a limited storage capacity, so older web pages may be automatically deleted from the cache to make space for newer ones. If Jose had waited a longer time before trying to access the page, it might not have been available in the cache, and he would have needed an Internet connection to open it.
