Flash, Optical & Removable Storage for A+
Short answer
Removable media are primarily about portability and ad-hoc file transfer or legacy installs. USB flash drives and memory cards are flash-based, convenient for quick transfers. External drives are enclosed HDDs or SSDs for larger portable storage. Optical media is largely legacy but still encountered for installs or media playback in some environments. The technician should match the media type to the scenario (e.g., quick file transfer vs. long-term archival vs. legacy install).
Why it appears on the exam
- Given a short support scenario (transfer 10 files from phone to PC), select the most appropriate removable medium and why. - Identify a device from a short description or photo ("small stick with USB connector").
Key concepts
Concept 1
Required terms
USB flash drive: A small removable flash-memory storage device that connects via USB for portable file transfer. memory card: A small removable flash storage card used in cameras, phones, and some laptops (e.g., SD, microSD). external drive: A full drive (HDD or SSD) enclosed in an external case that connects typically via USB or other external interfaces. optical media: CD/DVD/Blu-ray discs used for software installation, media playback, or archival in some legacy contexts.
Example
Use a USB flash drive to transfer a few documents between machines.

How Flash, Optical & Removable Storage works
Removable media are primarily about portability and ad-hoc file transfer or legacy installs. USB flash drives and memory cards are flash-based, convenient for quick transfers. External drives are enclosed HDDs or SSDs for larger portable storage. Optical media is largely legacy but still encountered for installs or media playback in some environments. The technician should match the media type to the scenario (e.g., quick file transfer vs. long-term archival vs. legacy install).
Example
Use an external HDD to move a large media library or as a temporary backup during migration.
Concept 3
Common confusion
Treating optical media as common modern install media or assuming all devices can read any memory card without an adapter. Another confusion is equating external enclosures with internal performance; the external interface (USB 2.0 vs 3.1 vs Thunderbolt) constrains speed.
Example
Insert an SD card from a camera into a card reader to import photos.
Concept 4
Core 1 (220-1201) question cues
Given a short support scenario (transfer 10 files from phone to PC), select the most appropriate removable medium and why; Identify a device from a short description or photo ("small stick with USB connector").
Example
Use an optical disc only when an installer or recovery media is explicitly provided on CD/DVD/Blu-ray.
