I. Introduction to the Framework
A frames page is a collection of pages consisting of a common set of web pages, usually in a set of frames, where navigation is placed on one page, and other content that needs to be changed on another page. The main reason for using frames page I think is probably to make navigation clearer, make the structure of the site more simple and clear. Let's take a look at the following example of this website, as shown in figure one.

For Gigabit Ethernet, 1000Mbit data can be transmitted per second, i.e. 125000000b/s, with a fixed cost per Ethernet frame: Preamble and Frame start preamble (8B), MAC (12B), type (2B), payload (46b~ 1500B), CRC (4B), Gap (12B), so the smallest Ethernet frame is 84B, can send 1488000 frames per second. The largest Ethernet fr
And friends to play, found Loadmovie first file and secondary file playback frame frequency problem, haha, and friends to discuss the next, really interesting! In fact, a main file 1.swf in the Loadmovie into a secondary file 2.swf, the main frame frequency is to remain the same, or follow the main file frame frequency? This question mm company seems to have a te
The HTTP2 was formally finalized on February 28, 2015 through an IETF organization approval release. The contents of it can be consulted: HTTP2 Overview http://www.cnblogs.com/ghj1976/p/4552583.html. In HTTP2 network communication, frame is the smallest transmission unit in communication and contains at least one Frame header, which can indicate which Stream it belongs to. A specific request resembles the f

In order to obtain high compression ratio and high-quality images with random access under the condition of efficient compression encoding, MPEG definesI, P, BThree image formats: intra picture and predictedPicture) and bidirec tional picture, that is, I, P, and B, used to represent the frame sequence of the 1/30 s interval. To meet random access requirements, only image I informa
Objective:In iOS development often encounter two words frame and bounds, this article mainly elaborated frame and bound difference, especially bound very around, more difficult to understand.First, take a look at the accepted information:See the following code first you must understand something:-(CGRect) frame{ return cgrectmake (SELF.FRAME.ORIGIN.X,SELF.F
window frame structure is to combine two or more than two pages of pages, can use the same window to open the structure, that is, multiple pages together to show the effect of a page.A window frame structure includes two aspects of the Web page file, one is the window frame settings file, tells the browser what content files, how to arrange, and another or severa
Introduction to Frame Relay is a high-performance WAN protocol. It runs on the first and second layers of the OSI reference model, that is, the physical layer and the data link layer. Ii.

3. Packet Switching Network: Through packet switching, network devices can share a point to transfer data packets between devices through the operator network. Packet Switching mainly uses the statistical multiplexing technology to achieve circuit sharing. Such as frame relay, ATM, and X.25.

Frame relay is a grouping method used to
1, frame can not be separated from frameset alone, IFRAME May;2, frame can not be placed in the body, as shown below:The following does not display properly:3, nested in the frameset of the IFRAME must be placed in the body, the following can be displayed as normal:The following does not display properly:4, not nested in the frameset of the IFRAME can be used freely;The following can be displayed as normal:
The frame page contains three tags: frame, IFRAME, and frameset. Beginners can easily confuse the three. The following describes the differences between the three.
10.4.1 difference between frameset and FrameFirst, we will explain the differences between frameset and frame.

Note:
Understand the source, currentsource, and content attributes of the frame in the navigation, and the URI and content attributes of the navigationeventargs type in the navigation event.
In the navigating and navigated events of the frame, insert the following debugging:Code:
Debug.Writeline ("Navigationeventargs. Uri :" +E.Uri );
Debug.Writeline ("Navigationeventargs. Content :" +E.Content );

Recently, some windows have been written using the wx module of python. wx. Frame is the most important window framework, and some materials are searched online. Its common attributes are used as follows:
Wx. Frame (parent, id =-1, title = "", pos = wx. DefaultPosition, size = wx. DefaultSize, style = wx. DEFAULT_FRAME_STYLE, name = "frame ")
The most basic synchronization method in data communication is "bit synchronization" (bit synchronization) or bit synchronization. Bits are the smallest unit of data transfer. Bit synchronization (bit synchronization) means that the receiving end clock has been adjusted to the same as the sending end clock, so the receiver receives the bitstream and is able to adjudicate in the middle of each bit (as shown). Bit synchronization (bit synchronization) is intended to properly receive each bit sent

For the first network programming developers, the communication protocol design is generally confused. This aspect is also less relevant in general web-programming books. Guess it's too easy. This piece is really not difficult, but if you don't know it, it's easy to get out of a basket or detour. Let's talk about protocol design based on TCP/UDP.
1, TCP-based protocol design
TCP is a stream-based protocol. But most Web applicat
The example that this section shares for you is the use of Wxpython frame.

Virtual circuit switching has been introduced in previous articles, see: http://blog.csdn.net/todd911/article/details/9069447
Here we will introduce the two middle-Wan technology using virtual circuit switching: Frame Relay and ATM.Frame Relay
Frame relay is a virtual circuit wide area network. Designed to meet the new Wan
Cross-references between framesAll frames in a page are provided as properties of the Window object in the form of a collection, for example: Window.frames represents a collection of all the frames within the page, similar to the form objects, linked objects, picture objects, and so on, and these collections are the properties of the document. Therefore, to refer to a child frame, you can use the following syntax:
Copy Code code as follows:
