If it doesn’t have the answer, it will provide a referral to another DNS server. This method reduces load on individual servers but may require additional queries from clients.

HTTP vs. HTTPS: What’s the Difference?

The distinction between HTTP and HTTPS is vital for understanding web security:

  • HTTP (Hypertext Transfer Protocol): This protocol is used for transmitting data over the web but does not encrypt data, making it vulnerable to interception.
  • HTTPS (Hypertext Transfer Protocol Secure): HTTPS adds a layer of security by encrypting data using SSL/TLS protocols. This ensures that sensitive information, such as login credentials and payment details, is protected during transmission.

SASE vs. SD-WAN: What’s the Difference?

Both Secure Access Service Edge (SASE) and Software-Defined Wide Area Network (SD-WAN) are essential for modern network architectures:

  • SASE: Combines networking and security functions into a single cloud service, providing secure access to applications regardless of user location. It focuses on delivering comprehensive security alongside connectivity.
  • SD-WAN: Primarily focuses on optimizing WAN performance by intelligently directing traffic across multiple connections (e.g., MPLS, broadband). While it enhances connectivity, it does not inherently include security features.

Cloud Networking vs. Cloud Computing: What’s the Difference?

Understanding cloud networking in relation to cloud computing is crucial for IT professionals:

  • Cloud Networking: Refers to the use of networking technologies and services delivered over the internet. It includes virtual networks, VPNs, and cloud-based firewalls that facilitate secure communication between cloud resources.
  • Cloud Computing: Involves delivering computing services (storage, processing power, applications) over the internet. It allows users to access resources on-demand without managing physical infrastructure.
