What are some technical challenges and questions that arise from the need to represent digital information in computers and transfer it between people and computational devices?

security

Explanation:

One technical issue that arises from this is security. Many times the information that is being transferred is private or even valuable, therefore grabbing the attention of hackers/thief's that want this information. This makes security highly important, but making sure that the information is completely secure is impossible. The best that can be done is adding certain safety measures to secure the information as much as possible, which in term is a technical challenge.
