The Language of Technology
This module builds the basic vocabulary of technology: hardware and software, the operating system, RAM versus storage, applications versus online services. Anyone who holds these four distinctions can judge device problems and purchase decisions far more clearly.
In this module
- You can tell hardware from software and roughly judge which side a problem is on
- You can explain what the operating system does and why its updates matter
- You know the RAM–storage difference and can trace "my phone is full" and "my phone is slow" to the right place
- You start asking, for any service you use, whether your data lives on your device or on a server
Why language first?
Much of the helplessness people feel with technology comes not from missing information but from tangled concepts. Someone who says "my phone is full" without knowing whether it is a RAM or a storage problem reaches for the wrong fixes; someone who cannot separate an application from an online service cannot say where their data lives. This module sharpens four fundamental distinctions. Once they settle in, the backup and security topics of the later modules become far easier to grasp.
The order of the lessons
The module moves from the outside in. Hardware and Software establishes the most basic pairing. Operating System introduces the manager between the two. RAM and Storage separates the two most confused concepts. Application and Online Service carries the boundary beyond the device into the cloud, laying the ground for the next module, Files, Cloud and Backups.
Lessons
- Application and Online ServiceAn application installed on your device and an online service used over the internet are different things — and the difference matters most in a single question
- Hardware and SoftwareHardware and software are technology's most fundamental pair: one is the physical parts you can touch, the other the instructions telling those parts what to do
- Operating SystemThe operating system is your device's invisible manager: it mediates between hardware and applications, shares out resources and maintains security. This lesson
- RAM and Storage"My phone is full" and "my phone is slow" concern two different parts: storage and RAM. Through the desk-and-filing-cabinet analogy, this lesson separates the t
