remaining frames. Then, it is sent to the system CPU for further processing. When the computer sends data, the network adapter waits for the appropriate time to insert the group into the data stream. Whether the received system notifies the computer of the complete arrival of the message. If there is a problem, the recipient will be asked to resend the message. 　　2.

For more details, see click to open the link. Here, I will only talk about my views. This is based on slots. I think it is very helpful to establish a good mathematical model in your mind. Each slot is defined as a node {key, flag, pre, next} You need a free linked list and a single-chain table. The header is free = 0; Define two functions that operate the free linked list. This is easy to think of: removing a node from the free linked list removefro

The synchronousqueue described in the previous article is a one-way data transfer between 2 threads, one put, one take.And today's exchange, continue, is a two-way data transfer, 2 threads at a sync point, exchanging information. Its use is roughly as follows: Exchange In the above example, 4 threads concurrently invoke Exchange and 22 interact with the data. May be A/b, C/D, may also A/C, b/d, or A/D, b/c. Exchange Implementation From a simple point of view, Exchange needs only one mutex varia

In addition, you can turn on 54Mbps mode. Some wireless ap/routers to "compatible" with more wireless network cards, does not turn on its G mode, we can set "wireless mode" to Gmode (g mode), the "Transfer (TX) rate" set to 54Mbps, activate 8X mode, and "Antenna transmission power" set to the highest, In order to speed up the tra

We had better not use Windows XP Wireless management, but install the network card with the program, this setting, there will be more options, display is the author of the network card with the program settings, which has the corresponding 8X mode, and can

Use of wireless network card One, the classification of wireless network card Wireless card can be divided into: built-in wireless network card and external wireless network card. 1, built-in wireless network card Built-in wireless card is divided into two types: a desktop-specific PCI interface wireless network card. (Figure I) a MINI-PCI wireless network card that is built into a notebook computer. (Figure II) Figure I Figure II 2, external wireless network card

The "Centrino" notebook is already equipped with a wireless network card. The other is a desktop-specific PCI interface wireless network card Desktops Of course can also be w

big taboo in Qt programming. In Qt, all qpaintdevices must be created and used with a QApplication instance. If you are curious, you can mention that QLabel inherits from QWidget, and QWidget is a subclass of QPaintDevice. The above code is normal because the label is disabled when the app exits. In this way, all qpaintdevices of the label are not accessible. However, if the component is not closed when the app exits, the program will crash. (If you want to know how to exit the app, but the com

Signals and Slots Signals and slots are used for communication between objects. The signal/slot mechanism is a central feature of QT and may be the most distinct part of QT and other toolkits. In graphical user interface programming, we often expect a change in one widget to be notified to another window widget. More generally, we want objects of any kind to be able to communicate with other objects. For example, if we are parsing an XML file, and wh

Signal and Slots are used for communication between objects. It is one of the core features of Qt and is also the most significant difference between QT and other frameworks.OverviewIn GUI programming, if we change a control, we may want other controls to know; in other words, we want any type of Object to be able to communicate with each other.Some tookits use callback functions for communication, and if you want to advertise some events in a function, you need to use a function pointer in this
