Over the recent years, technology has increasingly improved. The world has become extremely reliant on technology and computers. Although there are many good things that come out of computers and many advantages, there are also many disadvantages that can create an unsafe environment. Three major ways computers have made the world safer is the improvements on security, medical advancements, and enhanced public safety. Throughout the years, cybersecurity has improved especially with the new technology. While the risk of cyber attacks has increased, we have been able to identify those risks with the improved technology to prevent those attacks from occurring. Computers have enabled the resources and tools for when people encounter those attacks. Computers have provided people with advanced technology such as using two factor authentication, which makes it harder for hackers to attack people. The second way computers have made the world a safer place is its contribution to medical advancements. One improvement that computers contribute to in the healthcare system is Electronic Health Records. This has made it easier to track health records and improve the ability to diagnose medical issues and prevent them from possibly occurring. The last benefit of computers is they have enhanced public safety. Because of computers, we can easily communicate with one another. Computers have a large contribution to Law Enforcement by being able to track and use GPS systems and store and collect information. Computers have made it possible for us to track down and expose criminals with the GPS system. Three major ways computers have made the world less safe are social media, cybercrime, and vulnerability. Society has become extremely dependent on social media for news and information. While this can be a good thing, not everything you read on social media is correct. It is important that people do their own research before believing everything they read. Social media overall has had many negative impacts especially on young teens. It is very easy to get cyber bullied through social media. The second negative impact of computers is cybercrime. Computers have made it easier for cyber attackers to hack companies and people’s personal information. Computers contributed to people becoming more vulnerable to potential online threats.
