Script var old = null; function changemenu (myp) {var obj = document. getElementById (myp); if (old! = Null old! = Obj) old. style. display = 'none'; old = obj; if (obj. style. display = 'none') {obj. style. display = 'block'

It's a man's next layer 100 [sixth layer] -- high imitation Douban client, 100 Layer High imitation Some time ago, sunshine Xiaoqiang installed a Douban client. The first time it was opened, it was attracted by this interface style. This morning, when I started Douban to listen to music, I suddenly had a thought, to achieve this effect, open the client and analyz

Drive development will certainly encounter the application layer and the core layer of communication problems, first of all, the kernel layer and the application layer of communication can be divided into two aspects, the first is the application layer to the core

Compare the OSI seven layer model and the TCP/IP four layer model The OSI seven-layer model enables reliable communication between different networks of different systems through seven hierarchical structural models, so its main function is to help different types of hosts achieve data transfer. The nodes that complete the relay function are often referred

I'm going to go down to the two and three layers of the switch. A two-tier switch is equivalent to dividing an interface into multiple interfaces, just to provide a lot of interfaces; (if the landlord is not a professional person can ignore the following content) theoretically it can be understood that the switch does not split the broadcast domain, but split the conflict domain The three-tier switch has a certain routing function (do not know how much the landlord knows about the router, if y

This article describes how PS creates layer replicas and a little secret that few people know about a PS layer replica. 　　First, PS build the meaning of the layer copy A member asked PS How to create a layer copy. Before we answer this question, let's take a look at what is the meaning of the PS

Today, from their practical use to talk about the service and the DAO layer of understanding, I hope you god guidance. DAO layer and Service layer in the interface is the same, two layers of understanding and difference in the implementation class, 1.dao layer is directly related to the database, in the implementation

OSI Layer-7 network model and TCP/IP layer-4 Network Model Original by Mu ant Community Www.mumayi.net, this post address: http://bbs.mumayi.net/viewthread.php? Tid = 932283 1. OSI network layered Reference Model Network Protocol designers should not design a single, huge protocol to provide complete details for all forms of communication, but should divide communication problems into multiple small pro

A great advantage of LWIP is that it supports standard socket applications, which can completely mask the underlying interactive process and bring a lot of convenience to use. Today, as an example of socket creation, connection, transceiver The process of data interaction between the socket layer and the protocol stack layer. (1) Socket creation App Layer Socket

What is the Mac Sublayer and the LLC sublayer of the data link layer?The main functions of the MAC sub-layer include the encapsulation/uninstallation of data frames, the addressing and recognition of frames, the reception and transmission of frames, the management of links, the difference of fr

In today's Photoshop tutorial, we'll share with you the knowledge about locking layers and Jian Tu layers. We know that when a layer is locked, the layer cannot be edited, so there are users who need to unlock the layer in order to be able to edit a layer. Below, just take a look at today's Photoshop lock

Recent projects have encountered some of the mask layer problems, summed up: Pop mask Layer Mask layer Pop-up There are a lot of methods, here only write my code, using the JQ operation Dom method to implement. #bg为透明度为0.6, a Mask page,. Box is a button on the mask layer. Pop-up Mask $ ("#bg").

Basic OSI Layer-7 model knowledge and common applications at each layer (1) OSI Open Source Initiative (OSI) is a non-profit organization designed to promote the development of Open Source software. The full name of the OSI Reference Model (OSI/RM) is the Open System Interconnection Reference Model (OSI/RM ), it is a network system interconnection model proposed by ISO. It is the foundation of network tech

In the protocol stack, the transport layer is above the network layer, the Transport Layer protocol provides logical communication for the processes running on different hosts, and the Network layer protocol provides logical communication for different hosts. The difference is subtle, but it's very important. Let's use

When the first run, please press F5 refresh, load remote jquery to see the effect, click the left mouse button, pop-up

Two-tier switch:The second layer switching technology is more mature, two layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address to forward, and these MAC addresses and corresponding ports recorded in their own internal table of addresses. Specific as follows:(1) When the switch receives a pa

Bo is engaged in a FPGA, has not really studied Ethernet-related technology, and now finally can calm down the heart to learn, I hope that they can more in-depth grasp the most basic communication interface technology. Here's the start.I. OSI Reference ModelToday we first learn about Ethernet is the most basic and important knowledge--osi Reference model. 1. Source of the OSIOSI (Open System Interconnect), open systemsInterconnection. Generally called the OSI Reference Model, ISO (International

Differences between an ISO 7-layer model and an ISO 5-Layer Model TCP/IPThe layered model (TCP/IP layering model) is also known as the Internet layered model or the Internet Reference Model (InternetReference Model) ISO layer-7 Model The Open System Interconnection model is a universal global standard developed by the International Standards Organization in 1984.
