telephone Splitter? What is a separator?
Answer: ADSL separates the low-frequency and high-frequency signals transmitted by ordinary telephone lines by means of the frequency division technology. Less than Hz is used by telephone; higher than Hz is used by the Internet, that is, data and voice signals are transmitted separately on the same copper line, and data signals are not transmitted through telephone switches. In this way, high-speed transmissi
directly operate the data in the user State Space of the process .) First, let's take a look at the reactor mode. The reactor mode is applied to synchronous I/O scenarios. Take the read operation and write operation as examples to see the specific steps in the reactor: read operation: 1. the application registers the read-ready event and the associated event Processor 2. event splitter waits for the occurrence of an event. 3. when a read-ready event

Have you ever found a problem? Let's place a component. The original positioning of the component is to give the coordinates and high values of the widget so that Qt can know the position of the component. When the user changes the size of the window, the component remains quietly in the original position, which is obviously not very difficult. Therefore, Qt provides a mechanism-layout to solve this problem. You j

The named slot is used to improve decoupling so that different carousel content is set according to different situations when the parent component is used.
In addition, you need to set the page splitter, that is, the page indicator in the image carousel, common indicators such as small dots, or digital indicators.

During our installation and use of ADSL, there will be many unexpected situations, so we need to learn how to judge these situations:
1. The ADSL filter is best connected to the entry of the telecommunication bus.
If you have installed a telephone extension or other equipment such as a fax machine on your ADSL line, you need to take full advantage of the filter attached to the ADSL Modem. The ADSL filter splitter is best connected to the telecom bus i
After the ADSL installation is completed, you will be waiting for the installation personnel to come to the door for installation. You should know about the installation method. Otherwise, you will not know how to solve the problem if you change the installation method in the future or encounter some minor problems.
The installation of ADSL mainly includes: 1. installation of equipment and lines; 2. Installation of software.
First, let's take a look at the installation and cabling of ADSL device

Read operation:
1.Application Registration requires the event and associated event Processor
2.Event splitter waiting for event occurrence
3.When an event is required for reading, the event splitter calls the event processor registered in step 1.
4.The event processor first performs the actual read operation, and then further processes the read content.
