CBC is a specific operational mode in encryption. In this mode, each plaintext block is exclusive-OR'd orXORed(numerically combined) with the previous ciphertext block and then encrypted. An XOR is a coding mec
What Does Boolean Mean? Boolean refers to a system of logical thought that is used to create true/false statements. A Boolean value expresses a truth value (which can be either true or false). Boolean expressions use the operators AND, OR, XOR and NOT to compare values and return a true...
For binary strings, Hamming distance is equal to the number of ones in d(strOne XOR strTwo). Here are a few of the important terminologies that you might encounter during your learning journey: Hamming Weight: The “Hamming weight,” within the context of computer science and information theor...
I'm sorry, but if someone does not know the security risks, they need to learn them before they do any coding. And, I haven't even started on the performance issues related to EF, though the Obama Care web site does come to mind. EF is an OK tool for prototyping, but people ...
In tennis what’s a bagel? What is a “bounced check”? What does “shortchange” mean? What does it mean to “clock out”? What is shock value? What does “be the bigger man” mean? What does “rube” mean? What is “careerism”? What is a “haunt”? Meaning of “get feet ...
What does this mean? Simply means that the attacker set up unattended access on the victim machine and then restarted the host. This unattended access means the attacker can connect at anytime by using a password they set, or tricked the user into setting, on the host. Next we see that...
Please hang in there. We’re almost finished. So, Erasure Coding Does What? Erasure coding is a mathematical calculation for protecting data. It uses a coding method to protect data from unwanted “erasures” – like hard drive failures. And that’s where it gets its name. ...
Logical XOR (^) Logical OR (|) It is vital to understand the difference between the & and && operators when they are used in an expression where two conditions have to be evaluated. While the & operator always executes both conditions, && does not execute the second on failure of the fi...
Consider the following C-like program: int fun(int *i) { *i +=5; return 4; } void main() { int x = 3; x = x + fun(&x); } What is the value of "x" after the assignment statement in main, assuming a) What does a double reference (&&) in C++ mean? (a) How do we...
Does it mean they are capable of complex, human-like cognition? Even more controversially, to what extent does it make sense to talk about “cognition” in the context of organisms that don’t even have a nervous system, such as plants? And if one considers the flow of information between...
