Before a friend asked me whether dual-line dual IP host will have an impact on the site SEO, because before the replacement of two IP server caused by the site keyword SEO rankings decline, the problem has not been contacted before, on the internet to find a lot of information, but also have a certain understanding, so today also take in and discuss with everyone, Dual
The dual-interface card is a smart card based on a single chip that integrates contact and Non-Contact Interfaces. It has two operation interfaces for Chip access, you can access the chip either by means of contact or by means of RF. There is only one chip on the card, and two interfaces can perform the same operation through both the contact interface and the non-contact interface.
There are three types of Dual

The NetBurst architecture has been in its 7th year since its release in 2000. Over the years, the processor in this architecture has been changing, with the core experiencing Willamette, Northwood, Prescott, Cedar Mill, Processor process from the first 0.18 micron to 65 nm, the main frequency from the initial 1.3GHz to the current 3.8GHz, processor cache, front-end bus and such as HT technology, EM64T, eist technology, etc. are added to the NetBurst architecture based Pentium 4 series pr
Recently implemented a project to use a domestic dual-machine hot-standby products, but in the database to do two-machine hot standby There are some problems, there is no way. Have to study it! After two days of research finally the problem was solved. Record problem-handling steps for later use and hopefully help people who need it.First,First introduce our environment: two servers + one storage + two dual

The dual-machine Hot Standby software can detect computer operating systems, network systems, and databases in a timely manner. When any system has problems, the dual-machine software can automatically run on the backup server, let the slave server take over the work of the host so that the computer will never stop an
I talked about dual-display in the unit yesterday.

Hot Standby is a high-reliability application solution that combines software and hardware. The dual-machine hot standby system consists of two independent servers and corresponding control software. The two servers act as a single system in the networ
Today most computers have such a feature: CPU integrated core graphics card, plus the computer also equipped with a stand-alone graphics card, such a computer has dual graphics cards, under normal circumstances, dual graphics cards will automatically switch intelligent operation. However, due to the CPU integrated graphics performance is limited, not comparable to the independent graphics, in addition to th
Free and available IPv4 addresses will soon be "exhausted". Over the years, this has prompted most general operating systems to begin to add IPv6 support. However, many applications (such as VPN clients and server software) are not ready for IPv6. This will lead to the situation where the dual-protocol stack host deployment does not support IPv6 VPN software, thus opening the door for security vulnerabilities and causing VPN traffic leakage. In this a

Reason for dual-boot Linux?One of the most important components of a computer is the operating system. In fact, a powerful operating system should have software compatibility and be able to smoothly implement interaction between hardware and software. For most users, Linux + Windows or Linux + Mac OS is often the most ideal combination.
In daily use, we can use dual systems on the same device. Windows and L
