QUESTIONS AND ANSWER LATEST 2026
What is the best explanation for why digital data is represented in computers in binary?
It's easier, cheaper, and more reliable to build machines and devices that only have to distinguish
between binary states.
What is the 4-bit binary number for the decimal number Ten (10)?
1010
What is the minimum number of bits you would need to encode the 26 letters of the alphabet plus a
space - a total of 27 characters?
5 bits
Number systems with different bases such as binary (base-2), octal (base-8), decimal (base-10), and
hexadecimal (base-16), are all used to view and represent digital data.
Which of the following is NOT true about representing digital data?
When data is large enough computers switch to using decimal representation instead of binary,
because you can represent larger numbers with fewer digits.
Consider the following three binary numbers:

A middle school is expanding to open a high school next year, doubling the total number of students.
The school keeps a database in which each student's unique ID number is stored as an 8 bit number
called studentID. Before the arrival of the new students almost every 8 bit number has already been
assigned to a student. Of the options provided below, which is the smallest change to the way studentID
is represented necessary to ensure each incoming student receives a unique ID?
Add a bit to studentID to double the number of IDs that the database can represent.
A user clicks on a website, and it begins to load immediately, but it takes a long time to load completely
and pictures appear slowly, one by one. Which of the following is demonstrated through this situation?
Low bandwidth, low latency
8 bits is enough to represent 256 different numbers. How many total bits do you need to represent 512
(twice as many) numbers?
9 bits
ASCII is a character-encoding scheme that uses a numeric value to represent each character. For
example, the uppercase letter "G" is represented by the decimal (base 10) value 71. A partial list of
characters and their corresponding ASCII values are shown in the table below. (See Code.Org Unit 1 Ch 1

ASCII characters can also be represented by binary numbers. According to ASCII character encoding,
which of the following letters is represented by the 8-bit binary value: 0100 0010
