Which service assigns a user-friendly name to an IP address?

CDN (Content Delivery Network)
DNS
HTTP
Load Balancer

The correct answer is: DNS

The correct answer is DNS (Domain Name System). DNS serves the critical function of translating human-readable domain names (like www.example.com) into machine-readable IP addresses (like 192.0.2.1). This makes it easier for users to access websites and services without having to remember complex numerical addresses. When you type a web address into your browser, it is the DNS that resolves that name to the corresponding IP address, allowing your browser to connect to the correct server. The other options serve different purposes. A Content Delivery Network optimizes content delivery to users based on geographic proximity, enhancing performance and reducing latency. HTTP (Hypertext Transfer Protocol) is the foundational protocol for transmitting data over the web, but it does not interact directly with IP address resolution. A Load Balancer distributes network or application traffic across multiple servers, ensuring no single server becomes overwhelmed with too much traffic, but it does not assign user-friendly names to IP addresses.
