DNS英文表达方式

定义

Domain Name System, commonly known as DNS, is a decentralized database that maps domain names to IP addresses. It plays a crucial role in the internet, allowing users to access online resources using memorable domain names instead of complex IP addresses.

作用

The DNS enables users to navigate the internet more easily by translating human-readable domain names into machine-readable IP addresses. It ensures that when a user types a domain name into a web browser, the browser can quickly find the corresponding IP address and load the requested webpage.

结构

The DNS system consists of several components, including authoritative name servers, recursive name servers, and DNS resolvers. These components work together to provide a reliable and efficient way of resolving domain names to IP addresses.

DNS英文常见表达

DNS resolution

DNS resolution refers to the process of converting a domain name into an IP address. This process is performed by DNS resolvers, which query authoritative name servers to obtain the IP address associated with a given domain name.

DNS server

A DNS server is a computer that stores DNS records and responds to DNS queries. There are two types of DNS servers: authoritative name servers and recursive name servers. Authoritative name servers store the DNS records for a specific domain, while recursive name servers handle DNS queries from clients and forward them to authoritative name servers.

DNS caching

DNS caching is a technique used to store DNS records temporarily on a DNS resolver. This allows subsequent queries for the same domain name to be resolved more quickly, as the resolver does not need to query the authoritative name server again.

FAQs

Q: What is the difference between a domain name and an IP address?

A: A domain name is a human-readable name used to identify a website or other resource on the internet. An IP address is a numerical address assigned to each device connected to the internet. DNS translates domain names into IP addresses so that users can access websites using easy-to-remember names.

Q: How does DNS caching improve performance?

A: DNS caching stores DNS records temporarily on a DNS resolver. When a user requests a website, the resolver first checks its cache for the IP address associated with the domain name. If the record is found in the cache, the resolver can provide the IP address immediately, reducing the time it takes to resolve the domain name and load the website.
