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

There are a few signs that your computer might not be safe. For example, if you notice that your computer is running slower than usual, or if it’s freezing, crashing, or shutting down unexpectedly, it could be a sign that you have malware or a virus on your system. Additionally, if you notice that your files have been deleted or if new files have been added without your permission, it’s possible that someone has gained unauthorized access to your computer. To ensure that your computer is safe, be sure to install antivirus software and keep it up to date. You should also avoid downloading programs or files from untrusted sources, and be sure to regularly back up your important files to an external hard drive or cloud storage service. By taking these steps, you can help protect your computer from harm and keep your data safe.

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

Computers have had a significant impact on our world, both positive and negative. On the one hand, they have made our lives easier and safer in many ways. One way computers have made the world safer is through the use of security systems. With the help of computers, we can monitor and protect our homes, businesses, and cities more effectively. This has reduced crime rates and kept people safer. Another way computers have made the world safer is through medical advancements. Computers have played a vital role in developing new treatments and diagnoses for diseases. They have also made surgeries less invasive and more precise, reducing the risks associated with surgery. However, computers have also made the world less safe in several ways. One way is through cybercrime. Hackers can steal personal information, money, and intellectual property, causing significant harm to individuals and companies. Cybercrime is a growing threat, and it is becoming increasingly difficult to prevent. Another way computers have made the world less safe is through the development of autonomous weapons. These weapons can make decisions without human control, raising concerns about their use in warfare. They could cause unintended harm to civilians and lead to significant loss of life. Computers have both improved and diminished our safety. While they have made our lives easier and more convenient, we must also be aware of the potential risks associated with computer technology. It is important to continue to develop and implement safeguards to protect ourselves from the negative consequences of technological advancements.
