The question is What happens when you type google.com in your browser and press Enter? When you type https://www.google.com into your browser and press Enter, a series of complex processes are initiated behind the scenes that enable you to access Google’s search engine. These processes involve several different technologies working together seamlessly to deliver the requested content to your browser. In this blog post, we’ll explore what happens when you type https://www.google.com into your browser and press Enter.
DNS request
The first step in the process is a DNS request. DNS stands for Domain Name System, which is a protocol used to translate human-readable domain names like www.google.com into IP addresses, which are unique numerical identifiers that computers use to locate each other on the internet. Your computer sends a DNS request to a DNS server to find out the IP address associated with the domain name www.google.com.
TCP/IP
Once the IP address has been obtained, a connection is established between your computer and Google’s web server using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite. TCP/IP is a set of communication protocols that enables computers to exchange data over the internet.
Firewall
Before the connection is established, it must pass through a firewall, which is a security system that monitors and controls incoming and outgoing network traffic. The firewall checks to make sure that the incoming request is legitimate and doesn’t pose a security threat to the network.
HTTPS/SSL
Once the connection is established, your browser sends a request to the web server asking for the webpage associated with the URL you entered. Google’s web server responds by sending the requested webpage back to your browser using the HTTPS/SSL (Hypertext Transfer Protocol Secure/Secure Sockets Layer) protocol. HTTPS/SSL is a secure communication protocol that encrypts data to prevent eavesdropping and tampering.
Load-balancer
Before the webpage is sent back to your browser, it passes through a load-balancer, which is a device that distributes incoming network traffic across multiple servers to ensure that no single server becomes overloaded. Load-balancers also help improve the performance and availability of web services by directing traffic to the most available and responsive server.
Web server
The webpage is then processed by Google’s web server, which is a computer program that processes incoming requests and sends back responses. The web server retrieves the webpage from a database and processes it to generate the HTML, CSS, and JavaScript that make up the webpage.
Application server
Some web pages require more complex processing than can be handled by the web server alone. In such cases, the request is passed on to an application server, which is a computer program that processes application logic and retrieves data from databases or other sources. The application server generates dynamic content, such as search results or personalized recommendations.
Database
Finally, the application server retrieves any necessary data from a database, which is a collection of structured data that is stored and accessed electronically. The database contains all the information needed to generate the requested content, such as search results or product listings.
Conclusion
In conclusion, to know what happens when you type google.com in your browser and press Enter, typing https://www.google.com into your browser and pressing Enter initiates a series of complex processes involving DNS requests, TCP/IP communication, firewalls, HTTPS/SSL encryption, load-balancers, web servers, application servers, and databases. These technologies work together seamlessly to deliver the requested content to your browser, enabling you to access Google’s search engine and find the information you need.
