How does PHP do it? ------Solution--------------------Apache URL Rewrite technology, there are many ways to generate a. htaccess file similar to this. Rewriteengi

Java EE Cluster Generally speaking, Java EE cluster technology includes "load Balancing" and "failover" two parts. In the above illustration, load balancing means that a target object is requested by many client objects simultaneously. The load balancer is between the caller and the callee, and you can distribute the request to a target object with the same fu

the function of @Resource is equivalent to @autowired, but @autowired is injected automatically by Bytype, and @resource is automatically injected by default. @Resource There are two attributes that are important, the name and type,spring the Name property of the @resource annotation to the bean's name, and the type attribute to the Bean's. So if you use the Name

The so-called Bluetooth technology, in fact, is a short-range radio technology, the use of "Bluetooth technology" can effectively simplify the handheld computer, notebook and mobile phone handsets, such as mobile communication terminals, and can successfully simplify the communication between these devices and the Inte

. Based on the packet switching technology, the IP Data network protocol is used to make the data service of the existing GSM network break through the limit of the maximum rate of 9.6kbit/s, and the highest data rate can reach 164kbit/s. GPRS logically, in the GSM network structure to add two new network nodes to achieve: GPRS service support node (serving GPRS Support NODE,SGSN); GPRS Gateway support node

The 802.11ac standard is mainly designed to provide high throughput in the 5 GHz band, in addition to bringing fast and high-quality video streams, it also provides almost instantaneous data synchronization jobs and backups for laptops, tablets, and mobile phones. Theoretically, this specification will achieve at least 1 Gbit/s of multi-site WLAN throughput and at least 500 Mbit/s of maximum single-link throughput. This

Java TechnologyIt is both an advanced object-oriented programming language and a platform. Java technology is based on the concept of Java Virtual Machine (JVM)-A converter between language and underlying software and hardware. All Java implementations must implement JVM, so that Java programs can run on any JVM system. Java programming language(Java programming

The 802.11AC standard is designed to provide high throughput in 5GHz bands, in addition to bringing fast, high-quality video streaming, and providing almost instantaneous data synchronization jobs and backups for laptops, tablets and mobile phones. In theory, this specification will achieve at least 1gbit/s throughput of multiple-station WLANs and at least 500mbit/s maximum single link throughput. This is

Intel directed I/O virtualization Technology (VT-D) is an extension of Intel Virtualization Technology (VT), which provides virtualization solution assistance to the hardware. Vt-d is also adding support for I/O device virtualization on the basis of existing support for IA-32 (vt-x) and itanium® processor (vt-i) virtua

Intel Smart Cache Technology (Intel Advanced Smart Cache) is one of the 5 innovations included in the Intel Core Microarchitecture introduced in 2006, designed for multi-core processors that enable each kernel to dynamically leverage up to 100% of available level two cache resources. And at the same time fetch data from the cache at a higher throughput, effectively enhancing the execution efficiency of the

EJB is not a product. It is the specification of the Java server-side service framework, which is implemented by software vendors to implement the EJB server. Application developers can focus on the business logic needed to support applications without worrying about the implementation of the surrounding framework.The EJB specification explains in detail some of

The basic working principle of RFID technology is not complex: After a Tag enters the magnetic field, it receives the RF signal from the interpreter and sends the Passive Tag of the product information stored in the chip based on the energy obtained by the induction current, passive or passive tags), or actively send signals of a certain frequency Active tags, Active tags or Active tags); the interpreter re
