# Key Components of DNS

1. **Domain Registrars:** Companies where domains are registered (e.g., GoDaddy, Namecheap).
2. **Name Servers:** Servers that store DNS records and respond to DNS queries.
3. **DNS Records:** Data types like A (Address), CNAME (Alias), and MX (Mail Exchange) that define how the domain functions.

### Why Is DNS Important?

* **User-Friendly:** Simplifies internet navigation through recognizable names.
* **Global Connectivity:** Enables seamless communication across the web.
* **Reliability:** Ensures website availability with multiple redundant servers.
