Block (Internet)

On the Internet, a block (also sometimes referred to as a banhammer) is a technical measure intended to restrict access to information or resources. Blocking may be implemented by the owners of computers using software. Some countries, including China and Singapore, block access to certain news information. In the United States, the Children's Internet Protection Act requires schools receiving federal funded discount rates for Internet access to install software that blocks obscene content, pornography, and, where applicable, content “harmful to minors”.
