One friend claims that a dual-core system runs at twice the speed as a single-core system; another friend disagrees by saying th
lidiya [134]

Answer:

<u>the first friend</u>

Explanation:

It is important to <em>remember </em>that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having <em>"a dual brain" </em><em>to process information faster.</em>

Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are <em>faster</em> (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, <em>we know that without them being faster they can't run twice the applications and twice the data. </em>

Therefore, we can make the conclusion that the first friend's response is correct.

How to do this PLEASE HELP 80 points!
sp2606 [1]

When reading the story, you know that the code has been created by humans, so it might actually be english and use concepts like our number system, our computer code system (I'm thinking ASCII), things that you should not assume when decoding a real alien message.

Looking at the numbers I notice that digits 6 to 9 do not occur in the message, which is statistically unexpected. This leads me to believe the number base might be 6 rather than our common base 10. In the story there are insects mentioned. Insects have 6 legs, so this makes sense (after all, our base 10 was based on the number of fingers).

Next, I notice the code 052 appearing regularly, so that could be a space. Let's check a hypothesis. 052 in base 6 is 5*6+2 = 32. 32 is the ASCII code for a space!!

Now, a decoding algorithm is ready to be devised:

"for each number in the sequence, parse it as a base-6 number and then print out its corresponding ASCII value".

The following node.js snippet does this:

var code = ['220','241','255','245','052','313',

           '311','052','312','303','052','312',

           '252','245','052','205','241','251',

           '253','243','052','203','253','302',

           '251','244','303','301','053'];

           

var msg = "";

for (let n of code) {

   msg += String.fromCharCode(parseInt(n,6));

}

console.log(msg);


And the message is.........:

<em>Take us to the Magic Kingdom!</em>

So, do these aliens want to visit Disneyland????
