rj45 keychain

is similar to the RJ-11 telephone line in shape and exterior, but wider, due to the difference in size between the two (for 4 or 6-pin, RJ45 for 8-pin connectors ), obviously, the RJ45 plug cannot be inserted into the jack. In turn, it is physically feasible (the plug is smaller than the RJ45 jack), which makes people mistakenly think that the two should or can

1, keychain is a very useful local storage tool can completely replace nsuserdefault to use and more secure than Nsuserdefault. 2, Keychain relative to nsuserdefault the main point is that Nsuserdefault can only access the project Keychain said that all projects are common to read data across the project. 3, keychain o

I know no demo to see the blog is very painful, so the demo first: Https://github.com/rayshen/GIKeychainGroupDemoThe demo has 2 projects, you run any one will store a value, then run another will access the value of the previous app store, and modify.Official: https://developer.apple.com/library/ios/samplecode/GenericKeychain/Introduction/Intro.htmlBefore the blog used keychain, the implementation of the data Delete app can also save, but did not real

Application of RJ45 short circuit ring on gigabit Nic1. Topic OriginFor those who often work on multiple operating systems, using Windows as the host system with Vmware Workstation is already a standard Workstation. I personally traveled back and forth between Windows and Linux and used the notebook configuration as Windows 7 as the host, VMWare Workstation 9 to install the Virtual Machine CentOS and OpenBSD. Virtual Machine network connection is set

Use the keychain feature to save the unique identifier of the device ., Keychain ID Because the data stored in the IOS system is in the sandBox, the sandBox will no longer exist once the App is deleted. Fortunately, one exception is the keychain ). Generally, the IOS system uses NSUserDefaults to store data. However, for some private information, such as password

The RJ45 interface is typically used for data transmission, and the most common application is the NIC interface. RJ45 is a type of different joints; RJ45 head According to the order of the line there are two different ways, one is orange white, orange, green, blue, blue, white, green, brown, Brown, the other is green, white, green, orange, blue, blue, white, or

Let's talk about the playing style and Tactics of RJ45 line sequence. The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8 Note:568a:Green

We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional cable are somewhat different, but the function is similar. It is mainly used in the network between the operator optical end machine to the router this link, is commonly known as t

Author: it.com. cnhttp: // www.ccw.com.cn 19:26:19 I want to comment (0) Many people (including the author) think that 10 Base-T 10 m networks use four of the eight signal lines in the network cable, the 100 Base-t m uses all eight signal lines (or how fast ?). However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitte

iOS Keychain is a relatively independent space, and when our program (APP) is replaced or deleted, the content saved in keychain is not deleted. Relative to Nsuserdefaults, plist file preservation and other general way, keychain save more secure. So we will use keychain to save some private information, such as passwor

Recently in a project, the project did not register for login, but instead used a unique ID to indicate the user. This unique ID is basically used by IDFV. So, the question is, how to get the user to uninstall the app and install the app again in the same account.First introduce the following IDFV:IDFV (Identifierforvendor) is the first two parts of the cfbundleidentifier (reverse DNS format). For example, the bundle ID of an app is Com.companyName.appname, then IDFV is com.companyname. Applicat
