What are if and switch statements?
The purpose of this algorithm (in Matlab)
x = 0;
for num = 1:max
if mod(num,2) == 0
out = out + num;
end
end
To compute the sum of even numbers up to 'max'

What is 128 values?
A characteristic of the Internet that allows it to continue to function despite router and connection failures.
What is fault-tolerant?
Daily double!
x XOR (y XOR x)
false
The keyword used to declare a variable whose value should never change.
What is const?
Daily double!
The purpose of this algorithm (in Matlab):
x = vector(1)
for i = 2:len(vector)
if vector(i) > x
x = vector(i);
end
end
To find the maximum value in the list 'vector'?
10112 in decimal notation.
What is 11?
The means by which different devices from different manufactures can all effectively communicate on the Internet.
What are Internet protocols?

NOT ( (x XOR y) AND (x OR y) )
true
The three primary iterative control structures.
What are for loops, while loops, and do...while loops?
The value of x at the end of a run of this algorithm (in Matlab)
x = 10;
for num= 1:3
if mod(num,x) == 0
x = x+ num;
else
x = x - num;
end
end
