Q. The slowest transmission speeds are those of
✅ Correct Answer: (D)
Twisted-pair wire
Explanation:
Twisted-pair wire has the slowest transmission speed among the listed options. It is commonly used in traditional telephone lines and older networking systems. Although it is inexpensive and easy to install, it suffers from signal degradation and limited bandwidth compared to other media.
- Microwaves provide high-speed wireless transmission.
- Fiber-optic cable offers the fastest data transmission using light signals.
- Coaxial cable is faster than twisted-pair and commonly used in cable TV and internet.
