What is issued to a website in order for it to be validated as a trusted website?
> Certificate authority Explanation: Certificate authority (CA) information is stamped on all packets coming from a website to validate where they came from. If any packets are misdirected through an untrusted site, the browser will detect that the certificate is now invalid and will give the user a warning in the form of a dialog box. Extensions are one or more functions added to the browser that can be created by the affiliated browser or a third party. Hashing is a feature associated with password managers. Hashing generates a string of values (hash code) that jumbles the password into symbols and letters. Hash codes cannot be reversed, which makes them a good deterrent to security threats. The actual password is then saved in the account. You can configure the DNS (Domain Name System) with a list of valid sites. This means that you can allow or deny access to certain sites. However, DNS is not designed to validate trusted websites.
While browsing the internet, you notice that your browser performance is continually slowing down. Which of the following would MOST likely increase the overall performance of your web browser?

You can clear the cache to help improve the overall performance of your web browser. Enabling a pop-up blocker can prevent pop-up ads from appearing on web pages. And while this might help to access the web page content a little quicker, it would not significantly improve the overall performance of the web browser. Private browsing mode lets you visit websites without the browser keeping your search history, cookies or password information. However, in this scenario, switching to private browsing mode would not clear the cache, which is most likely causing the performance problem. Once you've created a browser account, there is a settings feature that lets you log into a browser from multiple systems with all information including bookmarks, password information and all security settings, synced.

The CA on the server will operate using the same authority as on a public site and will give the user a certificate warning if they try to visit their version of an untrusted site. Hashing is a feature associated with password managers. Hashing generates a string of values that jumbles the password into symbols and letters. Hash codes cannot be reversed, which makes them a good deterrent to security threats. The actual password is then saved to the account.

For example, once a user uses their password to access their account, an alert with a confirmation code will appear on another account, such as a separate email. It will then ask to validate that code. Extensions are one or more functions added to the browser that can be created by the affiliated browser or a third party.

However, it would not synchronize bookmarks across several computers. Private Browsing Mode lets you visit websites without the browser keeping your search history, cookies, or password information. However, it would not synchronize bookmarks across several computers. In order for browsers to quickly retrieve websites, they often save all the site locations visited, which is referred to as a cache.
