criteria To reduce costs, ensure synergy and improve the wider use of wireless technology, many organizations (e.g. the Institute of Electrical and Electronic Engineers (IEEE), Internet Engineering Task Force (IETF), Wireless Ethernet Compatibility Alliance (WECA) and the International Telecommunication Union (ITU) ) have been involved in several major standardization efforts. For example, the IEEE workgr

In 1990s, being able to access the Internet was the wish of many friends. Since the 21st Century, how to get a better speed has become the goal of the majority of users. However, just a few years have passed. Since last year, wireless Networks have entered the eyes of common users. I believe many users have considered the wireless networks. Especially for ordinary household and small-and medium-sized enterprise users, wired networks need to be affected by factors such as complex cabling and netw

Chinese brands such as TP-LINK, D-LINK, and Tsinghua Tongfang, the technical aspects are also more suitable for the domestic network environment. Interface Type for wireless network card purchase Wireless NICs are mainly divided into PCI, USB, and PCMCIA. PCI interface wireless NICs are mainly used for desktop computers at the cheapest price. USB interface wireless NICs are plug-and-play and easy to install, the motherboard can be installed and used as long as there is a USB interface, but the

The positioning function is a major feature of the wireless ZigBee network. The wireless ZigBee network technology based on IEEE 802.15.4 is not subject to interference. The positioning function is added. For details, see the following. Hope to help you. Positioning Positioning data can significantly increase the value of exchanged information in many applications. For patient monitoring, asset tracking, inventory control, preservation, warehousing, m

of its high mobility that many people rely more on wireless Internet access. In addition, the use of wireless networks is also one of the information exchange methods used by small and medium-sized enterprises. However, setting up an office wireless device is not as simple as we think. Buying some equipment is just as simple as assembling it. It contains many factors before the establishment of the office LAN, the main problems include the coverage of office wireless signals, the security of wi

authentication mechanism, the wireless security is achieved. Physical address filtering and service area identifier matching can only solve limited security problems. To further address security issues, the Wired Equivalent confidentiality (Wired Equivalent Privacy, WEP) protocol is pushed to the forefront. WEP is used to protect link layer data in Wireless LAN. WEP uses 40-bit, 64-bit, and 128-bit keys, and adopts the RC4 symmetric encryption algorithm to encrypt data and access control at the

When purchasing LAN switches, you should pay attention to the following points:● ShapeLAN switches have two shapes. Generally, a vswitch with less than 16 ports is a desktop switch. A rack-mounted switch with more than 16 ports can be placed in a standard 19 inch rack or cabinet. In addition to fixed Ethernet interfaces, some vswitches often provide 1 ~ Two expansion slots are used to configure different extension modules, such as optical transceiver module, three-layer switching module, and sta

0 (| V |1, binary decimal2. IEEE Floating point representationThe IEEE floating-point standard represents a number in the form of V = ( -1) ^sxmx2^e: Symbol: s Determines whether the number is negative (S=1) or positive (s=0), while the symbolic bit interpretation for the value 0 is handled as a special case. Mantissa: M is a binary decimal, and its range is 1~2-ε, or 0~1-ε.

, so the product of the two includes a factor of 22k, and division removes the scale factor. Depending on the use of the results, you may need to adjust the proportions. This can be achieved using the shift operation common sense, but the shift operation defines only unsigned integers. If the underlying hardware uses a complement or symbolic size notation, you will usually get a wrong answer. Even for two of the complement, shifting a negative number can sometimes produce the wrong answer. (or y

Over a decade or so ago, CACM's articles were almost all classic. However, in recent yearsThe academic quality of the database is reduced slightly. IEEE transaction on computers is the IEEE's best computer publication. However, due to the characteristics of IEEEFoc

Although almost every processor andProgramming LanguageAll support floating point operations, but mostProgramStaff seldom pay attention to it. This is easy to understand-most of us seldom need non-integer types. In addition to scientific computing and occasional timing or benchmarking procedures, it is almost useless in other cases. Similarly, most developers can easily ignore arbitrary decimal numbers provided by Java. Math. bigdecimal-they are not used by most applications. However, in an inte

To make the frames sent by a network adapter receive and process the frames correctly, IEEE stipulates that each network adapter has a unique ethernet address-MAC address (which is called MAC address by IEEE ). Because the addressing details are defined by MAC protocols such as 802.3 ). The MAC address has 48 bits (6 bytes), which are usually expressed in hexadecimal notation. For example, 0000.0c12.3456 is

This solution enables good matching between MAC and PHY, and reduces the number of pins and chip area. The Single-Chip Ethernet microcontroller also reduces power consumption, especially when the power loss mode is used.Q: What is an Ethern
