Identify the switching technique in which the message is sent in one go, but it is divided into smaller pieces, and they are sent individually. The pieces are given a unique number and addresses to identify their order at the receiving end.

Correct option is B

The switching technique described, where the message is sent in one go but divided into smaller pieces (called packets), is known as Packet Switching. In this technique, the message is broken into smaller packets, each of which is sent independently over the network. Each packet is given a unique number and address, which helps in reassembling them in the correct order at the receiving end. Packet switching is widely used in networks like the Internet because it is efficient and allows for better utilization of network resources.
Important Key Points:
1. Division of Data: The message is divided into smaller packets, which are transmitted independently over the network.
2. Unique Identification: Each packet has a unique identifier (such as a sequence number) and address to help reassemble the message in the correct order.
3. Efficient Use of Resources: Packet switching allows multiple messages to share the same network resources, making it more efficient and scalable.
4. No Dedicated Path: Unlike circuit switching, there is no dedicated communication path for each message, so the network can handle more data traffic.
5. Error Handling: If a packet is lost or corrupted, it can be retransmitted without affecting the entire message.
Knowledge Booster:
· Option (a): Message Switching involves the whole message being sent to a central node where it is stored temporarily and forwarded. The message is not divided into smaller pieces, so it does not match the description of dividing a message into packets.
· Option (c): Binary Switching is not a standard or widely recognized switching technique in networking. The term is unclear and does not apply to the context described.
· Option (d): Circuit Switching establishes a dedicated communication path between the sender and receiver for the entire duration of the transmission. It does not involve breaking the message into smaller pieces; rather, it transmits the message as a whole.
