What is Net Neutrality?

A breakdown of net neutrality, including its benefits and disadvantages

The principle dictates that all internet traffic should be treated equally by internet service providers and that they cannot block, slow, or charge more fees for access to specific webpages. This would help ensure equal access to the internet and prevent larger companies from paying to prioritize access to their content, but it would require greater government intervention.

Learn how governments around the world restrict internet access for their citizens

Various countries around the world, including China, Russia, and Iran, control their local DNS infrastructure, allowing them to block access to online content by preventing the internet "phone book" from finding the IP addresses for specific URLs. Government-controlled internet service providers can also cut off access entirely or throttle specific traffic.

Learn about the protocols that make navigating the internet possible

While TCP/IP sends data in packets to the correct destination and checks for errors, UDP omits such safety features to speed up data transfer for real-time communication and streaming. Software rules such as HTTP and HTTPS enable the transfer of content on the World Wide Web, while SMTP handles email messages between servers.

View the ecosystem of global services, organizations, and agencies behind the internet

Through an open, transparent, and collaborative model built on open standards development and shared global ownership, the internet is kept freely accessible amid evolving international policies. Key organizations, such as IANA, which allocates IP addresses and fulfills administrative functions for the Domain Name System, function as non-profit organizations.

Section 230 is the law that shaped the modern internet—and free speech online

Passed as part of the Communications Decency Act, Section 230 shields online platforms from legal liability for user-generated content while allowing them to moderate it and host speech freely, making it one of the most debated laws governing free expression today.

The history of the National Science Foundation Network, a precursor of the internet

Although ARPANET connected various national laboratories and supercomputing facilities by the 1970s to facilitate scientific collaboration, the system was slow and required highly trained operators. The launch of NSFNET in 1986 provided a more flexible and powerful network that went on to connect over 170 academic and research communities and link to its European counterpart, EASInet.

Learn about Web3 and how it differs from past versions of the internet

Web3 is the idea of a new, decentralized internet built on blockchain technology. It aims to shift control from centralized entities like big tech companies to users through distributed ledgers and smart contracts. Key components include cryptocurrencies, NFTs, and decentralized autonomous organizations (DAOs) that operate without a central authority. Web3 promises more user privacy, ownership, and control over data and digital assets.

Contrary to popular belief, Netflix didn't kill Blockbuster

Blockbuster was definitely the loser in its years-long battle with Netflix, but the conventional wisdom that the streaming giant killed the established video store chain is incorrect. Blockbuster’s large debt load—and an activist shareholder who didn’t fully appreciate the threat Netflix posed—led the chain to squander its advantages.

An explanation of isotopes, which can help scientists trace food, water, and farming choices

Atoms of the same element have the same number of protons, but experiments showed that atoms of the same element can move through electromagnetic fields as if they had different masses. These differences in mass come from variations in the number of neutrons, which contribute to the stability of atoms by providing a buffer to the repulsion between protons.

Learn how a neural network works, why it matters, and how it can be trained to recognize patterns, classify data, and forecast future events.

Understanding how non-profit entities manage electric grids to ensure supply-demand balance

Independent System Operators in smaller areas and Regional Transmission Organizations that operate across multiple states run wholesale electricity markets. Electricity suppliers can submit competitive bids to meet estimated demand in day-ahead markets while keeping consumer costs low. ISOs and RCOs also inform markets of deviations in these estimates so that suppliers can adjust how much power they generate, which is then bought and sold in real time.

Patents arguably grant inventors monopolies for a short period of time

As a way to reward innovation, the government grants short-term monopolies on patented products. Patents block other companies from producing or selling that product, giving inventors the rights and opportunity to establish themselves in a market before other competitors enter.

'NIL' in college sports refers to 'name, image, and likeness'

In 2021, the NCAA began allowing its student-athletes to profit from using their name, image, and likeness, now often called NIL. While this is now permitted by the NCAA, state law (and school policies) largely dictate what is permitted.

Card issuers are financial institutions that open credit to customers, while card networks facilitate purchases between merchants and customers

Card issuers give customers credit cards, set rate limits, and collect payments. Card networks, on the other hand, dictate where credit cards can actually be used by managing relationships between the network and merchants. These networks make money on interchange fees, which merchants pay to accept a specific card network at their stores.

View the transparency of Earth's atmosphere and how it blocks most forms of light

The gases that make up Earth's atmosphere block most harmful forms of electromagnetic radiation from reaching the planet's surface, except for some ultraviolet light. Their transparency to radio waves means this form of light can reach Earth's surface, which is why most radio telescopes are ground-based rather than space-based.
