Web URLs, HTTP, and DNS Concepts Summary
Web URLs
A web URL, or Uniform Resource Locator, is a specific address that identifies a particular resource, such as a web page, image, video, or document on the internet. It consists of three parts separated by dots:
Protocol: This indicates the communication protocol used to access the resource, such as HTTP (Hypertext Transfer Protocol) or HTTPS (Secure Hypertext Transfer Protocol).
Domain name: This is the name of the website or server hosting the resource. For example, in the URL "google.com", "google" is the domain name.
Path name: This is the specific file path within the website or server. For example, in the URL "images/picture.jpg", "images" is the path name.
HTTP (Hypertext Transfer Protocol)
HTTP is a protocol that enables web browsers to communicate with websites and servers to access and display web content. It defines a set of rules that govern the transfer of data between the client (web browser) and the server.
DNS (Domain Name System)
The Domain Name System (DNS) is a hierarchical and distributed network that translates human-readable domain names into machine-readable IP addresses. DNS servers maintain a database of domain names and their corresponding IP addresses. When a web browser enters a domain name in the address bar, the DNS server translates it into the corresponding IP address. This enables the web browser to establish a connection with the server and retrieve the requested resource
