Which Device Fits? — TechKnowSurge

About this interactive

What you are doing: reading what a person needs, and the limits they can live with, then choosing the device that fits best. Every device in this module is a computer; what separates them is what each one trades away. The trade-offs, from the lessons. A desktop is not portable, but it is the easiest to upgrade, and parts from many vendors fit together, which keeps the cost down. A laptop runs the same operating systems and apps as a desktop and has a battery, so it goes anywhere and keeps working through a power cut; in return it costs more, is harder to upgrade and repair, and is easier to steal. A tablet is used through its touchscreen and is mostly for entertainment and communication; its productivity apps are stripped down. A smartphone is a smaller tablet merged with a cellular phone: it makes calls and fits a pocket, but has fewer apps than a tablet because of its small screen. An e-reader is built for reading, with a special screen that causes less eye strain, and does little else. A Raspberry Pi is a small, inexpensive learning computer running a Linux of its own, good for signage, labs and hobby projects, but it has little processing power. A gaming console is easy to use and affordable for games, but it runs just the apps built for it. How to use it: look past the activity in each card (reading, games, video) to the limits that come with it, such as a pocket, a budget, an upgrade next year or a power cut. The limits decide the device. Each card is scored on its own, and each one explains its answer after you check.

What you'll learn

Choose the computing device that fits a stated need by weighing each form factor's trade-offs: portability, expandability, cost, battery, screen and apps
Tell a laptop from a tablet, a tablet from an e-reader or a smartphone, and a desktop or a Raspberry Pi from a gaming console by what each one gives up

Key terms

Desktop: A personal computer small enough to fit on a desk but generally not considered portable, used for a wide range of computing tasks.
Laptop: A portable computer small enough to fit on a lap, integrating display, keyboard, and internal components into a single compact form factor.
Tablet: A portable computer that uses a touchscreen as its primary means of interaction, designed for entertainment, communication, and basic productivity tasks.
Smartphone: A mobile device that combines cellular communication with computing capabilities, functioning essentially as a compact tablet capable of making phone calls and running applications.
E-reader: A portable electronic device designed primarily for reading digital versions of written material, featuring a screen optimized to reduce eye strain compared to tablets or smartphones.
Raspberry Pi: A small, inexpensive single-board computer developed by the Raspberry Pi Foundation for education, prototyping, and lightweight computing tasks.
Gaming Console: A dedicated electronic device designed primarily for playing video games, containing internal computing components similar to a standard computer but packaged for gaming purposes.
Single-Board Computer: A complete computer built on a single circuit board, integrating a CPU, RAM, and I/O interfaces into a compact, low-cost form factor.
