Logical vs Physical Address: Key Differences Explained
A Logical Address is the identifier your device or program sees—like a placeholder in a map. A Physical Address is the actual spot in hardware, such as a memory chip or MAC sticker, that the system finally touches.
People blur them because both sound like “where something lives.” Coders swap terms, IT staff label cables, gamers tweak settings, and everyone assumes they’re the same thing when they’re not.
Key Differences
Logical addresses are flexible, changeable, and used by software. Physical addresses are fixed, unique, and tied to real hardware. One is a name tag; the other is the actual seat.
Which One Should You Choose?
Let the system handle physical addresses. Work with logical ones when coding, networking, or troubleshooting—they’re safer to change and easier to understand.
Examples and Daily Life
Your phone’s IP is logical; its Wi-Fi MAC is physical. A file path on your laptop is logical; the SSD sector storing it is physical.
Can I change a physical address?
Usually no—it’s burned into the hardware. Some devices let you spoof it, but that’s advanced and risky.
Why does my game show both addresses?
The logical one helps the game talk to your system; the physical one confirms the right graphics card is being used.
Is a URL a logical address?
Yes. It’s a friendly name that browsers translate into physical server locations behind the scenes.
