III. The Internet, despite its vast array of benefits, also comes with certain limitations. One such limitation is the issue of misinformation and fake news, which can spread rapidly and mislead users. Additionally, there are concerns regarding online privacy and security, as personal information can be vulnerable to hacking and data breaches. Moreover, the Internet can contribute to a sedentary lifestyle, as excessive screen time may lead to health problems such as eye strain and obesity.
