Answer:
1) Computers use voltages and since voltages changes often, no specific voltage is set for each number in the decimal system. For this reason, binary is measured as a two-state system i.e. on or off. Also, to keep calculations simple and convert into binary online, computers use the binary number system
2) 8 bits
3) 1000000 bytes
Answer:
I think cold day instead
Explanation:
Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion.
Answer:
A database is an organized collection of structured information, or data, typically stored electronically in a computer system.
Answer:
This is a multicolinearity problem and the student should determine the variable(s) that cause(s) the problem and remove it.
Explanation:
This information means that there exists a linear combination between the independent variables. The problem might have developed due to multicolinearity producing almost perfectly linearly dependent columns.
This could also be as a results of single matrix created when the student use an incorrect indicator variables and included an additional indicator column which created linearly dependent columns.
Answer:
The resultant integer (decimal number) exceeds 3 bits.
Explanation:
The computer program uses 3 bits of the 4 bits of the computer system, counting from the least significant bit.
The decimal number 6 and 2 are "0110" and "0010"respectively, represented by the computer system.
The computer program represents the 6 and 2 with 3 bits from the least significant bit (that is, it counts from the right). so 6 and 2 becomes 110 and 010 respectively.
= 6 + 2 = 8
= "110" + "010" = "1000"
Adding 6 and 2 gives 8 represented as "1000" by the computer system, but the computer program represents as "000"
