The correct answer is that the HINFO record type provides descriptive information about a computer or operating system. Specifically, the HINFO record is utilized in DNS (Domain Name System) to convey details such as the type of hardware and operating system a host is using. This information can be useful for network management and troubleshooting purposes, allowing administrators and tools to understand the capabilities and characteristics of a host on the network.

The other record types do not serve the same purpose. The CNAME record, or Canonical Name record, is primarily used for aliasing one domain name to another, essentially mapping multiple domain names to a single canonical name. The SRV record is designed to define the location of specific services, indicating the hostname and port number for services running on the server. The NS record, or Name Server record, designates the authoritative name servers for a domain, pointing to the servers that contain DNS records for that domain. Each of these types plays a distinct role in DNS, but only the HINFO record offers descriptive information regarding the computer's hardware or operating system.
