What does `RANDOM(1, 6)` return in pseudocode?
A random integer between 1 and 6, inclusive.
What is the purpose of the following Python code?
```python
import random
c = random.randint(a, b)
```
To generate a random integer between 'a' and 'b' (inclusive) and assign it to the variable 'c'.
Predict the output:
```pseudocode
count ← 0
LOOP 5 TIMES
roll ← RANDOM(1, 2)
IF roll = 1
count ← count + 1
END IF
END LOOP
DISPLAY count
```
A number between 0 and 5, inclusive, representing the number of times 1 was rolled.
Complete the following Python code to generate a random number between 10 and 20:
```python
import random
number = random.______(10, 20)
```
randint
What is the output of this code?
```python
import random
random.seed(42)
print(random.randint(1, 10))
random.seed(42)
print(random.randint(1, 10))
```
The same number will be printed twice because the seed is set to the same value before each call to `randint()`.
Identify the error:
```python
import random
print(random.randInt(1, 10))
```
`random.randInt` should be `random.randint`. Python is case-sensitive.
Predict the output:
```pseudocode
number ← RANDOM(1, 10)
DISPLAY number
```
A random integer between 1 and 10 (inclusive).
Complete the pseudocode to simulate rolling a die:
```pseudocode
roll ← RANDOM(____, ____)
```
1, 6
What is the output of the following code?
```python
import random
numbers = [1, 2, 3, 4, 5]
print(random.choice(numbers))
```
A random element from the list `numbers` (i.e., 1, 2, 3, 4, or 5).
What is the output of this code?
```python
import random
random.seed(1)
print(random.random())
random.seed(1)
print(random.random())
```
The same random floating-point number between 0 and 1 will be printed twice.
What are the differences between the Internet and the World Wide Web?
Internet: The global network infrastructure. | World Wide Web: A service that uses the Internet to access linked hypertext documents.
What are the differences between ASCII and Unicode?
ASCII: Represents characters using 7 or 8 bits. | Unicode: Represents characters using a variable number of bits (up to 4 bytes), supporting a wider range of characters.
What are the differences between positive and negative impacts of the Internet?
Positive: Increased access to information, global communication. | Negative: Privacy concerns, cybersecurity risks.
What are the differences between `random.random()` and `random.randint()` in Python?
`random.random()`: Returns a random float between 0.0 and 1.0. | `random.randint(a, b)`: Returns a random integer between a and b (inclusive).
What are the differences between sequence and selection control structures?
Sequence: Instructions are executed in order. | Selection: Code blocks are executed based on a condition.
What are the differences between lossy and lossless data compression?
Lossy: Some data is lost during compression, reducing file size significantly. | Lossless: All data is preserved during compression, allowing for perfect reconstruction.
What are the differences between a client and a server?
Client: Requests services from a server. | Server: Provides services to clients.
What are the differences between a variable and a constant?
Variable: Its value can change during program execution. | Constant: Its value remains the same throughout program execution.
What are the differences between a compiler and an interpreter?
Compiler: Translates the entire source code into machine code before execution. | Interpreter: Translates and executes the source code line by line.
What are the differences between a firewall and antivirus software?
Firewall: Prevents unauthorized access to a network or computer. | Antivirus: Detects and removes malicious software from a computer.
What is a variable?
A named container that stores information which can change during program execution.
What are data types?
The type of data a variable can hold (e.g., integer, string, boolean).
What is a procedure?
A reusable block of code that performs a specific task.
What are parameters?
Inputs to procedures that allow them to operate on different data.
What are return values?
The result a procedure sends back after it completes its task.
What is the Internet?
A global network of interconnected computers that communicate using standard protocols.
What is the World Wide Web?
A system of linked hypertext documents accessed via the Internet.
What is HTML?
The language used to structure web pages.
What is binary?
The fundamental language of computers using 0s and 1s.
What is cybersecurity?
Measures taken to protect computer systems and networks from threats.
