A function contains a switch statement. Its case statement is located in a while loop at the same time (there is a case statement outside ). The expression in the switch calculates the remainder of the Division. The position where the execution starts in the while loop is determined by the remainder and the loop exits (without break ).

1. By obtaining the hardware ID method, carries on the contrast confirmation, carries on the drive downloading installs
(1) Open Device Manager, find the following logo yellow exclamation point device, the following illustration illustrates, in the "Network controller" click on the Mouse "right" to choose "Properties";
(2) Find "Details" and select the "Hardware ID" option in the prop
1. This problem occurs we need to check the correct installation of the motherboard chip sound card driver card, and then we have an unknown device or question mark in the Device Manager, as shown in the following figure;
2. Now we open the question mark error, and then you will see in the Open interface will see: Device PCI 0
Knowledge Point Analysis:
Teredo is an address assignment and inter-host automatic tunneling technology that helps users establish IPV6 unicast connections when Ipv6/ipv4 hosts are located behind one or more IPv4 NAT. IPV6 packets are sent as UDP messages based on IPV4.The exclamation point device "Teredo Tunneling Pseudo-Interface" appears in Device Manager because the operating system does not correctly

Linux device drivers are in the form of kernel modules, but the modules are not necessarily drivers. The driver can be compiled into the kernel, when configuring the kernel, if a configuration item is set to M, then it will be compiled with the kernel compiled into a module, but to add drivers to the kernel will make the kernel very large, and in addition, modify, delete the driver need to compile the kernel again, this is extremely troublesome. So th
Now the network is more and more common, more and more knowledge, the need for more memory, so the U disk is more and more widely used. All we have to do is to have a small U-plate to store all the files. But we also had a little trouble using the U disk. After we use the U disk, the Win7 system prompts "The device is in use" when it exits safely. Close any programs or windows that may be using the device,
Tags: adb shell multi-device adbIn our usual use of the ADB tool, you may encounter such problems, when the computer is linked to multiple devices, the simple use of the ADB shell link device, there will be an error. Let's take a specific look at how to deal with this situation: 1. First, we need to know which devices are linked to each other on the computer. Use the following command to return to the
(i): Interrupt of block device:Interrupt function: the REQUEST_IRQ () function links the interrupt service subroutine of the block device driver to the specific interrupt request line.The interrupt procedure for the driver's interrupt service subroutine is as follows:(1): The user process emits a different type of input or output request (read () system call), perhaps firstThrough high-speed buffer storage, the actual
Some of the devices used in the computer are not used at all, or encountered some devices are not normal use, we can view these devices, through the Device Manager can be processor, hard drive, storage controller, monitor, keyboard, mouse devices, image equipment and network adapters and so on equipment operation and management, So how do you disable the specified device? Let's take a look at the specific s
Fault Description:After cloning several virtual machines, the discovery can not configure the IP address and other information, using the Linux command: "Ifup eth0" also can not activate the network card,While using "Service network restart", an error occurred: Error:no suitable device found:no device found for connection "System eth0"Workaround:Based on this error, looked up on the internet, found a lot of
How to obtain a sequence number that uniquely identifies each Android device? There are many answers to this question, but most of them are valid only in some cases. Based on tests:
all devices can return a telephonymanager. getdeviceid ()
A telephonymanager. getsimserialnumber ()
for all CDMA devices, getsimserialnumber () Returns a null value!
All devices with a Google account can return oneAndroid_id
All CDMA
