What is sequence in programming?

Instructions are executed in order, one after the other.

What is selection in programming?

Code blocks are executed based on conditions (if, if-else).

What is iteration in programming?

Code blocks are repeated until a condition is met or for a specific number of times (loops).

What is the purpose of random number generation?

To introduce unpredictability and simulate real-world events in programs.

Describe the function of routers in the Internet.

Routers direct data packets between networks to ensure they reach their destination.

Explain the role of protocols in Internet communication.

Protocols are standard rules that enable computers to communicate with each other. Examples include TCP/IP, HTTP, and DNS.

What is data representation?

How data is encoded and stored in a computer system (e.g., binary, ASCII, Unicode).

What is data visualization?

Using charts and graphs to understand patterns in data.

What is data mining?

Discovering useful information from large datasets.

What is ethical computing?

Applying moral principles to the use of computers and technology, including privacy, avoiding bias, and respecting intellectual property.

What are the steps to generate a random number in Python?

Import the random module. 2. Use a function like random.randint(a, b) to generate a random integer between a and b, inclusive.

What are the steps to simulate rolling a six-sided die in pseudocode?

Use RANDOM(1, 6) to generate a random integer between 1 and 6.

What are the steps to protect against phishing attacks?

Be suspicious of unsolicited emails. 2. Verify the sender's identity. 3. Don't click on suspicious links. 4. Use strong passwords.

What are the general steps for data analysis?

Collect the data. 2. Clean the data. 3. Analyze the data. 4. Visualize the data. 5. Draw conclusions.

What are the steps to create a secure password?

Use a mix of uppercase and lowercase letters. 2. Include numbers and symbols. 3. Make it at least 12 characters long. 4. Avoid common words or phrases.

What are the steps to represent an image in a computer?

Divide the image into pixels. 2. Assign each pixel a color value (e.g., RGB). 3. Store the color values as binary data.

What are the steps to connect to the Internet?

Ensure you have a network interface card (NIC). 2. Connect to a network (e.g., Wi-Fi or Ethernet). 3. Configure your IP address and DNS settings. 4. Test the connection.

What are the steps to declare a variable in Python?

Choose a name for the variable. 2. Assign a value to the variable using the assignment operator (=). 3. The data type is automatically inferred.

What are the steps to write a basic HTML page?

Start with <!DOCTYPE html>. 2. Add the <html> tag. 3. Include <head> and <body> sections. 4. Add content within the <body> section.

What are the steps to protect your computer from malware?

Install antivirus software. 2. Keep your software up to date. 3. Be careful when opening email attachments. 4. Avoid suspicious websites.

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.
