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

The world has changed a lot because of computers. They have made some things safer while also adding new risks and weaknesses. To begin, they have changed the way people communicate and respond to emergencies, making it easier for information to get around more quickly during emergencies. Computer networks and communication technologies are used by emergency services to plan rescue efforts and get help to people quickly, which saves lives. Also, computer-driven improvements in healthcare have made patients safer and better their outcomes. Electronic health records and diagnostic tools that are run by computer programs give doctors access to more information about their patients and help them make more accurate diagnoses. This makes medical mistakes and bad reactions less likely. Computers are also very important for making transportation safer through improved navigation systems and technologies that avoid collisions. Computer algorithms and sensors in these systems find dangers and improve traffic flow, which lowers risks and crashes on land, at sea, in the air, and on the roads. On the other hand, computers bring about new problems and risks. Cybersecurity threats like ransomware, malware, and data hacks are becoming more common. These threats put people and businesses at risk of losing money and having their privacy violated. Concerns about privacy invasion and surveillance abuse are raised by the growing number of online tracking and surveillance technologies. This shows the need for stricter privacy laws and better data protection. Also, as people become more dependent on computers and other digital tools, they create security holes that bad people can use. When cyberattacks, technical problems, or natural disasters interrupt computer networks or important services, it can lead to a lot of problems, such as economic losses and threats to public safety. In conclusion, computers have definitely made many areas of life safer and more efficient, but they also bring about new problems and risks that need to be carefully managed and reduced. We can get the most out of computers while lowering their risks and weaknesses by tackling cybersecurity threats, improving privacy protections, and becoming less reliant on technology. This will make the digital future safer and more resilient.
