I am beginner to MQTT , but what is confusing me is it's basic definition
MQTT is a publish-subscribe based "light weight" messaging protocol'.
Based on my previous understanding on MQ (Message Queue), both MQ and MQTT sounds very same to me. Can any one elaborate what the real difference between MQ and MQTT is and their use case? Thanks!!

The MQ Telemetry (MQXR) service. This service runs inside the IBM MQ server, and uses the IBM MQ Telemetry Transport (MQTT) protocol to communicate with telemetry devices.
Although MQTT is not a message queue by definition, it can queue messages for clients.
Historically, the "MQ" in "MQTT" came from the IBM MQ (then 'MQSeries') product line, where it stands for "Message Queue". However, the protocol provides publish-and-subscribe messaging (no queues, in spite of the name).
MQTT is designed to be used for smaller devices that send messages over a network with low bandwidth. It is well-known for its simplicity (Only 5 Apis) and minimal wire footprint. On the other hand, RabbitMQ has been designed to be used for a variety of messaging scenarios that have developed over the last 25 years.
MQTT was initially called "Message Queue Telemetry Transport". You can find an in-depth explanation how it evolved here: http://www.hivemq.com/mqtt-essentials-part-1-introducing-mqtt/

MQTT is a protocol, it is open source. A lot of vendors are using this protocol for messaging.
MQ is an over-arching team that just means messaging. There are lot of different protocols, AMQP is one of them as well.
Additionally, IBM had a product called MQ.
