Rachel is planning on writing code that will have to do computations with very large numbers.
Which of the following is the most important issue she should check before writing her code? -
(answers)Rachel should look up how many bits are used to store integers and floating point
numbers in the programming language she is using.
Which of the following can be represented by a single binary digit? - (answers)Any integer
modulus 2. If a grade is passing or failing.
Which of the following is NOT a reason computers use hexademical? - (answers)Hexadecimal
shows no relation to the binary. 吗？还是指某个特定的词或概念
？
Why do computer scientists often prefer hexademical over other representations? -
(answers)Hexademical uses fewer digits than binary.
Consider the following: 0110 1011 0010 1011. This sequence represents - (answers)something
that depends on the context in which it is used
The following shows four different representations of data. Which of the following is true about
the representations of data? - (answers)All four do not represent the same hexadecimal data.
Which representation is at the lowest level of abstraction? - (answers)Binary digits: 0111 1111
0100 1100 1001
Consider the following statement.
"There are 10 types of people in this world: Those who understand binary, and those who don't."
Why might computer scientists find this statement humorous? - (answers)10 (binary) = 2
(decimal)
