Final answer:
Ransomware affects computer system functionality and files on the infected device but does not impact physical copies of files. It causes significant disruptions, particularly in business contexts.
Step-by-step explanation:
Once ransomware is present on a device, it can affect computer system functionality and the files on the infected device. Ransomware is a type of malicious software designed to block access to a computer system or encrypt files until a sum of money is paid. It does not typically affect physical copies of files as they are not part of the computer system. However, the impact on a device can be profound, leading to significant disruptions in personal and professional contexts, especially in business settings where device failures can lead to customer dissatisfaction and loss of revenue.
