What term describes the technique of sending data across a network in parts via different routes?

• A. Packet
• B. ASCII
• C. Data compression
• D. Packet switching

Answer: (D)

Splitting data into smaller chunks and sending them along different paths describes how packet switching works. In this approach, the message is broken into small packets. Each packet can travel via any available route to the destination, and they’re reassembled there to reconstruct the original data. This makes networks more efficient and robust because routes can change to dodge congestion or failures, and multiple paths can be used simultaneously.

An individual packet is just a unit of data, not the method itself; ASCII is about encoding characters, and data compression reduces size. None of those describe sending pieces of data over multiple routes.
