Network restrictions refer to limitations placed on internet access or usage within a specific network. These restrictions can be implemented by organizations, such as schools or businesses, to control the types of websites and online services that users can access. Common reasons for these restrictions include maintaining productivity, ensuring security, and protecting users from inappropriate content. Such restrictions can take various forms, including blocking certain websites, filtering content, or limiting bandwidth for specific applications. Tools like firewalls and proxy servers are often used to enforce these rules, helping to manage network traffic and safeguard sensitive information from potential threats.
