Question

1. journal prompt: this picture shows one of the worlds first computers, and two of the worlds first computer programmers. what are 3 ways this computer is different from computers that we use today? what are 2 ways that it is the same? what is 1 thing you think is true of all computers? 2) question of the day what is a computer? 3) reflection prompt: think of a problem that a computer can help you to solve. what is the information problem? what information does the computer need to solve that problem? what type of thinking work does the computer need to do to solve the problem?

Explanation:

1. Differences between early - and modern computers: Early computers were large, occupied entire rooms, had limited processing power, and used punch - cards for input. Modern computers are small, portable, have high processing power, and use a variety of input devices like keyboards, mice, and touch - screens.
2. Similarities: Both can perform arithmetic and logical operations, and both can store data (though early computers had much less storage capacity).
3. True of all computers: All computers can process data according to a set of instructions.
4. Definition of a computer: A computer is an electronic device that can accept data, process it according to a set of instructions (a program), and produce output.
5. Example problem: Suppose you want to analyze a large dataset of customer purchase records. The information problem is to find patterns in the data, such as which products are frequently bought together. The computer needs the raw purchase data (including product names, purchase dates, customer IDs, etc.). The computer needs to perform data - analysis tasks like sorting, filtering, and statistical calculations to solve the problem.

Answer:

1. Differences:

• Physical size: Early computers were huge, modern ones are small.
• Input method: Early used punch - cards, modern use keyboards/mice.
• Processing power: Early had low power, modern have high power.

1. Similarities:

• Can perform arithmetic operations.
• Can store data.

1. True of all computers: Can process data based on instructions.
2. Definition: An electronic device for data input, processing, and output.
3. Problem example:

• Information problem: Analyze customer purchase records for patterns.
• Needed information: Raw purchase data (product names, dates, customer IDs).
• Thinking work: Sorting, filtering, statistical calculations.
