What does z-index mean?

z-index is a CSS property that controls the order in which elements overlap on the page, similar to the order in which paper is stacked. Here's how it works: Every element has a default z-index value of 0. Elements with higher z-index values will overwrite elements with lower z-index values. z-index can be used to create floating elements, control the order of overlapping elements, and create three-dimensional effects. When using, you need to consider things such as avoiding overuse, using negative values, and paying attention to browser compatibility.

What is the root domain name server?

Root name servers are the foundation of DNS and are responsible for managing authoritative records for all top-level domains (TLDs), essentially the "phone book" of the Internet, converting domain names into IP addresses. They work by providing the address of the authoritative nameserver responsible for that top-level domain when the user enters a domain name. Root name servers are critical to the proper functioning of the Internet as they allow users to access any website, and are operated and maintained by ICANN to ensure the stability of the Internet.

The difference between root servers and root domain name servers

Root servers store the Internet's root zone (all top-level domain name TLDs), while root name servers store root zone information (containing information for all TLDs and their corresponding authoritative name servers). The number of root servers is 13, distributed around the world, and the number of root domain name servers is unlimited. Root servers determine which TLD's name servers to query, while root name servers provide information about the TLD's name servers.

The Importance of Root Domain Name Servers

Root domain name servers are vital to the Internet. Their functions include: parsing domain name requests and converting URLs into IP addresses. Maintain top-level domain name records to ensure domain name uniqueness and prevent conflicts. Provides DNS resolution to enable computers to access other devices. Provides stability to the Internet; failures can cause the Internet to crash. Respond to domain name changes and update records to ensure users are accessing the correct website. Keep the Internet safe with security protocols. Support new technologies like IPv6 and DNSSEC to adapt to changing environments.
