The web browser sends an HTTP request to the IP address, the IP address then sends the content that are displayed by the browser
Explanation:
The process of converting the typed in URL to a displayed page is as follows;
1) The typed in URL is sent to a DNS recursor by the browser
2) The recursor gets the DNS record for the domain from the cache if the record is cached or when the DNS record for the domain is not cached, the recursor makes a requests to the DNS root from which the name of the TLD nameserver is received
3) The TLD nameserver is contacted by the resolver to obtain the authoritative nameserver's IP address
4) With the information, the resolver contacts the authoritative nameserver and obtains the domain's IP address for the domain the resolver contacts
5) The obtained IP address for the URL's domain is then sent to the browser by the resolver
6) An HTTP request is sent by the browser to the IP address and the data received by the browser from that IP address is rendered and seen as the page content.
Solution:
It is done by Operating system.
An Operating system is system software that manages computer hardware and software resources and provides common services for computer programs.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.
