From Moon Landings to Modern Machines: How Computers Have Transformed
Then: The Computers That Took Us to the Moon
When Apollo 11 Moon Landing took humans to the Moon in 1969, the computers involved were astonishing… for their time.
But by today’s standards? Almost unbelievable.
- The Apollo Guidance Computer (AGC) had just 64 KB of memory
- It ran at about 0.043 MHz
- Programs were literally woven into rope memory by hand
- No screens as we know them — just simple numeric displays
Yet, this tiny computer:
- Controlled navigation
- Managed landing calculations
- Helped Neil Armstrong land safely on the Moon
All with less computing power than a modern calculator.
Now: The Power in Your Pocket
A typical smartphone now has:
- Millions of times more processing power
- Gigabytes of RAM (not kilobytes!)
- High-resolution graphics, AI processing, and constant internet access
Even everyday devices can:
- Run complex simulations
- Stream live video globally
- Use AI to recognise speech, faces, and patterns
What once filled a room now fits in your pocket — and does far more.
What Actually Changed?
It’s not just speed — it’s everything:
1. Miniaturisation
From room-sized machines to microscopic transistors on chips.
2. Storage Revolution
From woven memory → magnetic disks → solid-state drives → cloud storage.
3. User Interfaces
From switches and code → graphical interfaces → touchscreens → voice control.
4. Connectivity
Apollo computers were isolated. Today, everything is connected via the internet.
The Big Question for Students
If we could land on the Moon with such limited technology…
What could you achieve today with vastly more powerful tools?
Modern students have access to:
- Simulation software
- Coding platforms
- AI assistants
- Global collaboration
The challenge is no longer access to technology — it’s how effectively you use i
