Question

Accepted Answer

### Question 1: Binary Digits (Bits) can have what values?
# Brief Explanations:
Binary digits (bits) are the basic unit of information in computing. By definition, a bit can only take two values, which are 0 and 1. This is because the binary number system is base - 2, and each digit (bit) represents a power of 2, with only two possible states (off/0 or on/1).
# Answer:
Binary digits (bits) can have the values 0 and 1.

### Question 2: What is the number system that we use?
# Brief Explanations:
In our daily lives, for most common arithmetic operations, counting, and general number representation, we use the decimal number system. The decimal number system is base - 10, meaning it has 10 digits (0 - 9), and each place value is a power of 10 (e.g., units place is $10^0$, tens place is $10^1$, hundreds place is $10^2$, etc.).
# Answer:
The number system that we commonly use is the decimal number system (base - 10).

### Question 3: What are the different places in Binary Based on?
# Brief Explanations:
In the binary number system, similar to the decimal system, the place values of the digits are based on powers of the base of the number system. Since the base of the binary system is 2, each place (from right to left, starting from 0) represents a power of 2. For example, the right - most digit is the $2^0$ place, the next one to the left is the $2^1$ place, then $2^2$, and so on.
# Answer:
The different places in binary are based on powers of 2 (i.e., $2^0$, $2^1$, $2^2$, …).

### Question 4: One byte (8 bits) has how many different possible values?
# Explanation:
## Step 1: Recall the formula for the number of possible values of a binary number
For a binary number with $n$ bits, the number of different possible values is given by the formula $2^n$. This is because each bit can be either 0 or 1, so for $n$ bits, we have 2 choices for the first bit, 2 choices for the second bit, and so on. By the multiplication principle, the total number of combinations is $2	imes2	imes\cdots	imes2$ ($n$ times), which is $2^n$.
## Step 2: Substitute $n = 8$ into the formula
We know that a byte has $n = 8$ bits. So we calculate $2^8$.
$2^8=2	imes2	imes2	imes2	imes2	imes2	imes2	imes2 = 256$
# Answer:
One byte (8 bits) has 256 different possible values.

### Question 5: How does a computer store a negative number?
# Brief Explanations:
Computers typically store negative numbers using a method called two's complement. First, the positive equivalent of the number is represented in binary. Then, to get the two's complement, we first take the one's complement (flip all the bits, i.e., change 0s to 1s and 1s to 0s) and then add 1 to the result. Another common method is sign - magnitude, where the left - most bit is used as a sign bit (0 for positive, 1 for negative) and the remaining bits represent the magnitude of the number. However, two's complement is more commonly used because it simplifies arithmetic operations (addition and subtraction can be done using the same circuitry).
# Answer:
Computers commonly store negative numbers using two's complement. (Another method is sign - magnitude, but two's complement is more prevalent. In two's complement, the one's complement of the positive binary equivalent is taken and then 1 is added.)

### Question 6: What is the term for the first standardized collection of text?
# Brief Explanations:
The first standardized collection of text (for representing characters in computing) is ASCII (American Standard Code for Information Interchange). ASCII defines a standard way to represent characters (letters, numbers, punctuation marks, etc.) using 7 - bit or 8 - bit binary codes. It was developed to enable consistent communication and data representation between different computer systems.
# Answer:
The term for the first standardized collection of text (for character encoding) is ASCII (American Standard Code for Information Interchange).

### Question 7: What is the term for how computers can work with models? (Assuming "work with models" refers to working with different data types or representations, likely "abstraction" or "modeling" but more context - appropriate is "abstraction" or maybe "computational modeling". However, if it's about how computers handle different representations like binary for different data, another term could be "encoding". But a more likely term in the context of computer science and data representation is "abstraction" or "computational modeling". Alternatively, if it's about how computers process different types of data models, "data modeling" or "abstraction" is used. But a more common term related to how computers work with (represent) real - world models is "abstraction" or "computational modeling".)
# Brief Explanations:
In computer science, the term for how computers can work with models (represent real - world entities, processes, or systems in a simplified way for computation) is "abstraction" or "computational modeling". Abstraction involves representing complex real - world phenomena in a simplified form that can be processed by a computer. Computational modeling is the use of computers to simulate real - world systems or processes. Another related term could be "encoding" if it's about representing the model in a computer - readable format, but "abstraction" is more about the conceptual process of working with models.
# Answer:
A common term for how computers can work with models (represent and process real - world or conceptual models) is "abstraction" (or "computational modeling").

### Question 8: What new code was used to improve interoperability for people who spoke different languages?
# Brief Explanations:
To improve interoperability (the ability of different systems to work together) for people who spoke different languages, Unicode was developed. ASCII could only represent a limited set of characters (mostly English - language characters). Unicode is a character encoding standard that can represent almost all characters from all writing systems in the world. It includes characters from different languages, symbols, emojis, etc., allowing for consistent representation and exchange of text across different systems and languages.
# Answer:
The new code used to improve interoperability for people who spoke different languages is Unicode.
