What does “form factor” describe?

A form factor is a device’s physical shape and arrangement.

What is a system-on-a-chip (SoC)?

A system-on-a-chip (SoC) combines processing functions, often including the CPU and GPU, with other controllers on one chip.

What does RAM do, and how is it different from storage?

RAM temporarily holds data and programs in use. It is working memory, not permanent file storage.

What do display resolution and refresh rate measure?

Resolution describes pixel count; refresh rate describes how many times the screen updates per second.

Why can’t battery capacity alone predict a device’s runtime?

Laptop battery capacity is often given in watt-hours (Wh), while phone and tablet capacity is often given in milliamp-hours (mAh). These figures alone do not establish real-world battery life.

What does a USB-C-shaped connector tell you—and what does it not tell you?

The USB-C connector shape alone does not specify which data, display, or charging capabilities the device supports.

Why is processor clock speed alone insufficient for comparing performance?

Clock speed alone does not describe overall processor performance; compare the processor or SoC model and its capabilities.

How does a convertible 2-in-1 differ from a detachable 2-in-1?

A convertible’s screen and keyboard stay connected as its hinge folds or rotates; a detachable’s screen can separate from its keyboard.

What does device storage retain?

Storage retains the operating system, apps, and files when power is off.

What distinguishes an SSD from a hard disk drive?

An SSD has no spinning disks and is commonly used in laptops.

What are four common uses of Wi-Fi, Bluetooth, cellular, and NFC?

Wi-Fi connects to local networks, Bluetooth connects nearby accessories, cellular provides mobile-network service, and NFC supports short-range interactions such as contactless transactions.

What are the main roles of a CPU and GPU?

The CPU runs instructions and general-purpose tasks; the GPU renders images and video.
