Which term describes sending parts of data in different ways across a network?

• A. Packet
• B. Packet switching
• C. Data compression
• D. Colour depth

Answer: (B)

This question is about how data can be sent across a network using packet switching. In packet switching, a message is broken into smaller units called packets. Each packet can take its own route through the network and may arrive at different times. The destination then reassembles the packets into the original message, using sequence numbers and checksums to ensure everything fits back together correctly. This method makes network use more efficient and resilient, because other traffic can move through different paths and a single failed link won’t stop the whole transmission. The term describes the method of sending pieces along different paths, rather than the size of a single unit (a packet), reducing data size through compression, or color information in images.
