What is the key size of the International Data Encryption Algorithm (IDEA)?

Show Suggested Answer Hide Answer
Suggested Answer: C

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.

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.
