To maintain a centralized and hierarchical database system that efficiently manages and resolves domain names to their respective IP addresses.
To ensure the availability and accessibility of websites and other internet resources by enabling the routing of network traffic based on domain names.
so what is the answer
The function of the Domain Name System (DNS) can be summarized as follows:
1. Translating domain names into IP addresses: DNS acts as the intermediary that translates human-readable domain names (such as google.com) into IP addresses (such as 74.125.200.101) that computers can understand and use to communicate with each other.
2. Managing and resolving domain names: DNS maintains a hierarchical database system that efficiently manages and resolves domain names to their corresponding IP addresses. This allows computers to locate and connect with the correct resources on the internet.
3. Facilitating network traffic routing: DNS plays a crucial role in enabling the routing of network traffic based on domain names, ensuring the availability and accessibility of websites and other internet resources. It helps direct incoming requests to the appropriate IP address associated with the requested domain name.
To clarify, the option "To assign a unique domain name to every computer" is not accurate. DNS translates domain names to IP addresses but does not assign domain names to computers.
1. The function of the Domain Name System (DNS) is to translate domain names into IP addresses. This allows us to use domain names, such as www.example.com, instead of having to remember the corresponding IP address, such as 192.0.2.1.
2. Another function of DNS is to make sure that each IP address has only one corresponding domain name. This ensures that when we enter a domain name, we are directed to the correct IP address and website.
3. DNS does not sell websites to developers. Its primary purpose is to facilitate the translation of domain names to IP addresses and ensure the correct mapping between them.
4. DNS does not assign a unique domain name to every computer. Each computer on a network is typically assigned a unique IP address, while the DNS maps domain names to these IP addresses for easier identification and access.
The correct functions of the Domain Name System (DNS) are:
1. To translate domain names into IP addresses: DNS allows users to access websites using familiar domain names (e.g., www.example.com) instead of having to remember the corresponding IP address (e.g., 123.456.789.10). When a user enters a domain name in their web browser, the DNS system translates the domain name into the corresponding IP address, enabling the communication between the user's device and the server hosting the website.
2. To make sure that each IP address has only one corresponding domain name: DNS maintains a distributed database that maps domain names to specific IP addresses. This ensures that each IP address has a unique corresponding domain name, preventing conflicts and ensuring the accurate resolution of domain names.
3. To assign a unique domain name to every computer: While DNS does not assign domain names to individual computers, it does provide a system for registering and managing domain names. Domain names are registered by individuals or organizations who want to establish a presence on the web. DNS allows for the unique assignment and management of these domain names, which are then associated with the corresponding IP addresses of the servers hosting the associated websites.
It is important to note that DNS is not involved in the business of selling websites to developers, as mentioned in the incorrect response. DNS simply provides a critical infrastructure for translating and managing domain names.
