In which type of circuit switching is data delivery delayed because the data…

Concept

Circuit switching creates a dedicated end-to-end path for a communication session. Space-division switches form that path through physical crosspoints, whereas time-division switches share a digital path across time slots.

A time-slot interchange changes slot order by writing digital samples to memory and reading them at scheduled outgoing times. The required memory access introduces switching delay.

Application

The stem identifies a switch that stores data in RAM and later retrieves it. That is the memory-based operation of a time-slot interchange used in time-division switching.

Contrast

• Space-division switching uses spatially separate paths and crosspoints as its defining mechanism.

• Virtual-circuit switching is a packet-switching service that maintains a logical route for packets.

• Packet switching buffers and forwards packets rather than naming a circuit-switching division technique.

Cross-check

When an incoming sample is written to RAM and read into a chosen outgoing time slot, delivery waits for the scheduled read. This independently matches time-slot interchange.

Therefore, the answer is time-division switching.
