What allows ISPs to transmit data regardless of the content's details?

Net neutrality is the principle that ISPs must treat all data on the internet the same and not discriminate or charge differently by user, content, website, platform, application, or method of communication. This means that ISPs are required to provide access to all websites and online services equally, regardless of the details of the data being transmitted. This ensures that consumers can access the content of their choosing without interference.

Under net neutrality, data transmission remains unmodified by the service provider, which allows for a free and open internet where users can access any legal content without restrictions based on the type of data or its source. This principle is crucial for promoting innovation and ensuring fair competition among services on the internet.

While other options address aspects of internet services and management, they do not encompass the fundamental idea of treating all data equally the way net neutrality does. For example, a service level agreement refers to a contract between an ISP and its customer, while traffic shaping deals with controlling the flow of data. Data compression is a technique used to reduce the size of data for transmission but does not relate to how ISPs manage differing data content.
