What
does the prefix “bi” mean?
Correct Answer
D. Two
Explanation
The prefix "bi" in this context means "two". It is commonly used to indicate that there are two of something, such as in words like "bicycle" (two wheels) or "bilingual" (able to speak two languages).
2.
What is
a binary number?
Correct Answer
A. A number made up of ones and zeros
Explanation
A binary number is a number that is represented using only two digits, usually 0 and 1. This is because computers use a binary system, which means they can only understand and manipulate data in the form of binary numbers. Each digit in a binary number is called a bit, and it represents a power of 2. By using combinations of 0s and 1s, binary numbers can represent any kind of data, such as text, images, or instructions for a computer program.
3.
Why do
we use binary code to represent information stored in computers?
Correct Answer
A. Because computers are complex systems of switches.
Explanation
Computers use binary code to represent information because they are complex systems of switches. Binary code, which consists of only 0s and 1s, is the most efficient way to represent information using switches. Each switch can be in one of two states, on or off, which corresponds to the binary digits 0 and 1. By using binary code, computers can perform calculations and process data quickly and accurately.

The binary number 000111
represents what base-ten number?
Correct Answer
C. 7
Explanation
The binary number 000111 represents the base-ten number 7. In binary, each digit represents a power of 2, starting from the rightmost digit. The rightmost digit is 1, which represents 2^0 = 1. The next digit is also 1, representing 2^1 = 2. The next digit is 1 again, representing 2^2 = 4. Adding these values together, we get 1 + 2 + 4 = 7 in base-ten.
5.
Why do humans have a
base-ten system of numbers?
Correct Answer
C. Because we have ten fingers and ten toes.
Explanation
Humans have a base-ten system of numbers because we have ten fingers and ten toes. This means that we naturally count in groups of ten, which has influenced the development of our number system.
6.
One
program can understand every file type.
Correct Answer
B. False
Explanation
It is not possible for one program to understand every file type. Different file types have different formats and structures, and require specific programs or software to interpret and open them correctly. Each file type may have its own unique set of instructions and data that can only be understood by a program designed to handle that specific file type. Therefore, it is false to claim that one program can understand every file type.
7.
A file format is a way to
organize binary information into something.
Correct Answer
A. True
Explanation
A file format is a standardized way of organizing binary information, such as text, images, or videos, into a structured and recognizable format that can be easily understood and processed by computer systems. It defines the structure, encoding, and organization of data within a file, allowing different software applications to read, write, and interpret the data correctly. Therefore, the statement "A file format is a way to organize binary information into something" is true.
8.
The
binary number 0000101 represents the base-ten number two.
Correct Answer
B. False
9.
The
binary number 000001 represents the base ten number one.
Correct Answer
A. True
Explanation
The binary number 000001 represents the base ten number one because in binary, each digit represents a power of two. In this case, the rightmost digit is in the 2^0 position, which equals one. Therefore, the binary number 000001 is equal to one in base ten.
10.
A PDF
file is an almost universal file type.
Correct Answer
A. True
Explanation
A PDF file is considered an almost universal file type because it can be opened and viewed on almost any device or operating system without the need for specific software. This makes it easy to share and distribute documents across different platforms, ensuring that the content remains consistent and accessible to a wide range of users.
11.
Binary is...
Correct Answer
A. A system of ones and zeros used to represent information on a computer.
Explanation
Binary is a system used in computing to represent information using only two digits, 0 and 1. This system is known as base-2 because it uses two digits to represent any number or character. In binary, each digit is referred to as a bit, and a series of bits form binary code. Computers use binary code to store and process data, as it is the fundamental language understood by digital electronic devices. By using binary, complex operations and calculations can be performed efficiently, making it an essential component of computer systems.

A PDF is...
Correct Answer
B. A picture of a file that is un-editable.

When you walk into my classroom what should you do?
Correct Answer
B. Walk into my class quietly, look to the right hand side of the board and begin the do-now.
Explanation
The correct answer suggests that when entering the classroom, one should do so quietly and then direct their attention to the right side of the board to begin the assigned task or activity known as the "do-now." This implies that the teacher expects students to enter the classroom calmly and immediately engage in the provided work, rather than listening to a lecture or waiting for further instructions.
14.
When is the only time you should ask to use the bathroom?
Correct Answer
C. During your work time.
Explanation
Asking to use the bathroom during your work time is the only appropriate time to do so. During the do-now, students are expected to start their work immediately, and during the transition, students are expected to move from one activity to another. Asking to use the bathroom during these times would disrupt the flow of the class. Similarly, asking to use the bathroom during the lecturer's presentation would interrupt the lesson. Therefore, it is best to ask to use the bathroom during your designated work time when it is least likely to disrupt the class.
15.
During work time, what are my expectations?
Correct Answer
B. That students are quietly working on their assignments.
Explanation
The correct answer is "That students are quietly working on their assignments." This answer suggests that the speaker's expectation during work time is for the students to be engaged in their assignments without causing any disturbances or distractions. The use of the word "quietly" implies that the speaker expects a calm and focused working environment.
16.
If you have a question, what should you do?
Correct Answer
C. Raise your hand and wait to be called on.
Explanation
In a classroom or formal setting, when you have a question, it is considered polite and appropriate to raise your hand and wait to be called on. This allows the teacher or person in charge to maintain order and give everyone a fair chance to ask their questions. Shouting out or interrupting can disrupt the flow of the conversation and may be considered rude or disrespectful. By waiting to be called on, you show respect for others and the established rules of the setting.
