1.  How can you tell if your computer is safe?

2. Describe three ways that computers have made the world safer and less safe.

To determine if your computer is safe, several key practices should be applied. Firstly, the presence of reputable security software is vital. Using an unknown or not well-known security software could do the opposite and make your computer less safe. Regularly updating and scanning your system with an antivirus program enhances its resistance to malware and other cyber threats. Keeping the operating system and software applications up to date is equally crucial as developers release updates to address vulnerabilities. Regular backups are good to have in case of a sudden disaster of losing information or ransomware attacks. Activating and configuring a firewall adds an extra layer of protection controlling network traffic and safeguarding against unauthorized access. Having multiple layers of protection is always good and the more the better. Safe browsing practices, such as avoiding suspicious links and using secure connections, contribute to overall cybersecurity. These could lead to phishing or malware attacks which could result in identity theft or theft of personal information. Additionally, fortifying passwords and enabling two-factor authentication enhances account security, collectively forming a comprehensive approach to computer safety. Computers have played a transformative role in enhancing and, surprisingly, challenging safety across various domains. On the positive side, they have significantly improved communication and emergency response systems expediting information distribution during crises. In the healthcare sector, computers have led to medical advancements facilitating precise diagnostics and improving patient care. Enhanced transportation safety enabled by computerized systems in vehicles and air traffic control has contributed to safer travel experiences. On the other hand, the widespread use of computers has also introduced security risks. Cybercrime and data breaches pose threats to personal and corporate information, digital surveillance raises privacy concerns, and the weaponization of technology for cyber warfare jeopardizes national security. The dual impact of computers on safety underscores the importance of proactive measures to harness their benefits while mitigating associated risks.
