What does MQ mean?

First explanation: IBM MQ

Introduction:

Message Queuing (MQ) is an application-to-application communication method. Applications communicate by writing and retrieving application-specific data (messages) to and from queues without requiring a dedicated connection to link them. Message passing refers to programs communicating with each other by sending data in messages, rather than by making direct calls to each other, which is typically used for techniques such as remote procedure calls. Queuing refers to applications communicating through queues. The use of queues removes the requirement that receiving and sending applications execute simultaneously.

IBM WebSphere MQ products enable applications to communicate with each other through a network of different components such as processors, subsystems, operating systems, and communication protocols. For example, IBM WebSphere MQ supports more than 35 different operating systems.

IBM WebSphere MQ supports two different application programming interfaces: Java Message Service (JMS) and Message Queuing Interface (MQI). On IBM WebSphere MQ servers, JMS bindings are mapped to MQI. As shown in Figure 3, an application talks directly to its local queue manager by using MQI, which is a set of calls that request services from the queue manager. The interesting thing about MQI is that it only provides 13 calls. This means that it is a very easy-to-use interface for application programmers because most of the hard work is done transparently.

Figure 2. IBM WebSphere MQ programming

Figure 2 shows the principles of IBM WebSphere MQ programming. The first step is to have the application connect to the queue manager. It makes this connection through MQConnect calls. Next use the MQOpen call to open a queue for output. The application then uses MQPut calls to put its data on the queue. To receive data, the application calls the MQOpen call to open the input queue. Applications use MQGet calls to receive data from the queue.

The figure also shows the Message Channel Agent (MCA), channel exit, and Object Authority Manager (OAM). MCA is an IBM WebSphere MQ program that uses existing transport services such as TCP/IP and SNA to move messages from a local transport queue to a destination queue manager. These transport services are channels. Channel exits are user-written libraries that can be accessed from one of the defined location numbers during channel operation. OAM is the default authorization service for command and object management (for operating systems). These three components are important to existing security solutions for IBM WebSphere MQ.

The second explanation:

Moral Intelligence Quotient (MQ)

Moral Intelligence Quotient (abbreviated as MQ) refers to a person’s moral character level or moral character. The content of moral quotient includes various virtues such as consideration, respect, tolerance, forgiveness, honesty, responsibility, peace, loyalty, courtesy, humor and so on. In what we often call "morality, intelligence, and body", morality is put first; Coles said that character is better than knowledge. It can be seen that morality is the most important. A person with high moral integrity will definitely be trusted and respected, and will naturally have more opportunities for success.

The ancients said: "If you gain the Tao, you will get many help, but if you lose the Tao, there will be little help." success. Most of the truly successful people in ancient and modern times, both at home and abroad, have reached a very high level morally.

A large number of facts in reality show that the failure of many people is not a failure of ability, but a failure of life and morality.
