What does packet switching involve in data transmission?

• A. Splitting data into packets for transmission and reassembling at the destination
• B. Transmitting data as a single block
• C. Encrypting data into packets
• D. Storing packets on disk before sending

Answer: (A)

Packet switching is about breaking the data into smaller pieces, called packets, and sending those packets independently across the network. Each packet may take a different route and arrive at the destination out of order, but the recipient reassembles them into the original message. This approach makes efficient use of network resources, allows many conversations to share the same links, and can continue even if some paths are busy or fail. Encryption or buffering before sending aren’t defining features of packet switching. Encryption can be used with packets, but it doesn’t describe the switching process. Likewise, storing packets on disk before sending isn’t what packet switching is about; the key idea is splitting and later reassembling.
