JAVA was developed so that the same program could be executed on multiple hardware and operating system platforms, it is not Architecture Specific.
The following answers are incorrect:
Object-oriented. Is not correct because JAVA is object-oriented. It should use the object-oriented programming methodology.
Distributed. Is incorrect because JAVA was developed to be able to be distrubuted, run on multiple computer systems over a network.
Multithreaded. Is incorrect because JAVA is multi-threaded that is calls to subroutines as is the case with object-oriented programming.
A virus is a program that can replicate itself on a system but not necessarily spread itself by network connections.

Really? 128 bits seems too high for an older algorithm like IDEA.

I remember practicing a question about encryption algorithms, and I feel like IDEA had a smaller key size, maybe 64 bits?

Based on the requirements, I'd say Jekyll and DocFX are the two tools that can best handle the Markdown documentation, trigger the website recompilation, and integrate with GitHub.

Hmm, the key seems to be identifying the "less important" test activity in this context. I'll need to weigh the importance of each option against the information provided.

This seems like a straightforward pharmacology question. I'll think through the options and try to recall which medication is commonly used to treat diarrhea.

Ah, IDEA, the algorithm so secure it could probably encrypt a message even if you wrote it on a bar of soap and dropped it in the ocean.
