telecommunications systems?
A. Random placement of cables without standards
B. A standardized approach to cabling that organizes and manages
, network infrastructure
C. Wireless-only communication systems
D. Power distribution wiring in industrial plants
B
Structured cabling refers to a standardized system of organizing
telecommunications wiring to ensure efficiency, scalability, and
reliability in network installations.
3. Which organization is commonly responsible for defining Ethernet
cabling standards such as TIA/EIA-568?
A. ISO
B. IEEE
C. FCC
D. OSHA
B
The IEEE develops many networking standards, including Ethernet
protocols, while cabling standards like TIA/EIA-568 are widely
adopted in structured cabling practices for consistency and
performance.
