Estimate the bandwidth (bits/s) of a 747 crossing the Atlantic filled with CDs.

Problem Categorization

This estimation falls under the Infrastructure Estimations category, specifically focusing on bandwidth calculations.

Step 1

Clarify the Question

• Looking at the estimation context, are we considering a one-time transfer of data or a continuous stream? This affects whether we calculate total data transferred or data rate.

Why it matters: Determines if we focus on total capacity or transfer speed Expected answer: One-time transfer Impact on approach: Will calculate total data transferred rather than continuous bandwidth

• Considering the specifics of a 747, should we assume a standard passenger configuration or a cargo variant? This impacts the available space for CDs.

Why it matters: Affects the total number of CDs we can fit Expected answer: Standard passenger configuration Impact on approach: Will use passenger cabin volume for calculations

• Given that CDs are an older technology, should we assume standard CDs (700 MB) or more modern DVD or Blu-ray discs?

Why it matters: Significantly changes the data capacity per disc Expected answer: Standard CDs Impact on approach: Will use 700 MB per disc in calculations
