Software Architecture in Applications-01.png

This course offers a deep dive into the world of software architecture. It’s designed to equip software developers and architects with the knowledge and skills necessary to create, evaluate, and optimize software systems. The course covers a range of critical topics to ensure a strong foundation in architectural principles and strategies.

You will start by exploring architectural concepts and the relationship between quality attributes, requirements, and architectural styles. You’ll also examine different architectural patterns and strategies, including centralized and decentralized architecture, layered pattern, broker pattern, and microservices. Then, you’ll go into the details of important quality attributes needed while developing an architecture.

The course is equipped with multiple case studies and two projects to further enhance learning. These real-world scenarios and hands-on projects are strategically incorporated to give learners practical insights.

# Overview
**Domain name servers (DNS)** are key components of the internet that translate human-readable domain names (such as "google.com") into numerical IP addresses that computers use to interact with one another.

 
# How DNS works
When a user enters a domain name or clicks a hyperlink, the browser sends a request to a DNS server to resolve the domain name to an IP address. The DNS server searches its database for the domain name and delivers the appropriate IP address to the browser. The IP address is then used by the browser to connect to the server that hosts the website or service associated with the domain name.
