Also known as: Laptop, Notebook, Notebook computer
A laptop is a complete, portable personal computer with screen, keyboard, and battery built into one folding shell.1
Overview
A laptop runs the same full operating system and the same CPU, RAM, and storage building blocks as a desktop, just packed into a thin, battery-powered case. The packaging costs something: less room to expand, and in thin models the cooling can’t keep up, so the CPU slows itself down under load — thermal throttling — capping sustained performance.
What it buys in return is self-containment. Screen, keyboard, trackpad, battery, and wireless are all built in, so a laptop needs nothing but itself to be a working computer — the reason it has become the default machine for most people.
Trade-offs
Against the desktop, the laptop offers one decisive thing — it goes where you go:
| Factor | Laptop | Desktop |
|---|---|---|
| Portability | Goes anywhere | Stays put |
| Sustained performance | Throttles when thin | Full speed |
| Expandability | Minimal | Extensive |
| Power source | Battery or wall | Wall only |
| Everything built in | Yes | Separate parts |
For most developers that mobility outweighs the lost headroom, which is why the laptop is the default development machine.
Where it fits
A laptop is the natural field machine for GopherTrunk: SDR capture work runs fine on one, and it can go to the antenna, the car, or the site while the heavy replay and wideband DSP wait for a desktop bench. Phones and tablets, by contrast, are screens to view the data on rather than machines to capture it.
