Zorluk: OrtaDisplay Cables and Connectors

An IT technician is organizing a workstation deployment project and must categorize various display cables and interface specifications based on their physical characteristics and capabilities. Match each display cable connector type on the left with its corresponding technical capability or physical design feature on the right.

  • DB-15 (VGA)Legacy 15-pin three-row connector that carries analog RGB video signals exclusively
  • DVI-D Dual-Link24-pin digital-only interface capable of supporting resolutions up to 2560x1600 without analog pin support
  • DisplayPort20-pin connector featuring a mechanical locking latch and native support for Multi-Stream Transport (MST) daisy-chaining
  • USB-C with Alt ModeReversible compact interface that delivers native video traffic alongside power delivery and data over a single cable

Cevap

DB-15 (VGA) matches the legacy 15-pin analog RGB connector; DVI-D Dual-Link matches the 24-pin digital-only interface up to 2560x1600; DisplayPort matches the 20-pin latched connector supporting MST daisy-chaining; USB-C with Alt Mode matches the reversible compact interface providing video, data, and power over one cable.
Each display connection standard is accurately paired with its distinct physical interface, pin layout, and signal delivery mechanism standard to the CompTIA A+ Core 1 objectives.

Adım Adım Çözüm

1
Identify the signal type and pin layout for DB-15 (VGA)
DB-15 is recognized as a 15-pin connector in three rows carrying purely analog signals.
VGA is an older analog display standard using the DB-15 physical shell.
2
Differentiate DVI variants by signal and bandwidth capabilities
DVI-D indicates digital-only signals, and Dual-Link adds extra digital pins allowing high resolution (2560×16002560\times 1600).
DVI-D omits the analog pins around the flat blade while Dual-Link doubles the digital transmission bandwidth.
3
Analyze DisplayPort connector design and protocol features
DisplayPort features a 20-pin connector, physical latches for retention, and MST for multi-monitor daisy-chaining.
VESA DisplayPort specifications mandate packetized video data transmission enabling MST and secure latching mechanisms.
4
Evaluate USB Type-C Alternate Mode functionality
USB-C with Alt Mode leverages reversible pins to carry native video signals (such as DisplayPort) alongside USB host data and charging power.
Alternate Mode allows non-USB protocols to transmit over physical USB-C pins.

Anahtar Kavram

Identifying physical form factors, pin configurations, signal types (analog vs digital), and advanced protocol features (MST, Alt Mode) across display interfaces.
