ICT 0417 – Types and Components of Mobile Computer Systems

1. Types of Mobile Computers

Mobile computers are portable devices that can be used while moving or in locations without a fixed workstation. The main categories are:

  • Laptops / Notebooks – Full‑size keyboards, larger screens, and powerful processors.

  • Tablet PCs – Touch‑screen devices, often with detachable keyboards.

  • Smartphones – Small, handheld devices with cellular connectivity.

  • 2‑in‑1 Convertibles – Hybrid devices that function as both laptops and tablets.

  • Netbooks / Ultrabooks – Lightweight, low‑power laptops for basic tasks.

  • Handheld Gaming Consoles – Portable gaming devices such as the Nintendo Switch.

  • Wearable Computers – Smartwatches and AR glasses that provide limited computing functions.

  • Remotely Controlled Devices – Drones, robot vacuums, and other IoT devices that are operated via a mobile interface.

2. Core Components of Mobile Computers

Although the form factor varies, most mobile computers share a common set of hardware components.
