Blocking access refers to the act of preventing individuals or groups from reaching certain information, locations, or resources. This can occur in various contexts, such as on the internet, where websites may restrict users from viewing content based on geographic location or age. Organizations may also block access to specific areas within a building for security reasons. In the digital realm, blocking access can involve the use of software or hardware tools that filter or restrict online activities. For example, firewalls can be employed to block access to certain websites, while parental controls can limit children's exposure to inappropriate content.
