BLOB Binary Large Object
Database management system (DBMS) data format used in the name. By the name we can see it is usually large, in fact most of the information stored with the BLOB format, such as video picture files, audio files or other multimedia files, etc. File size is very easily exceed the general database or a numeric string the maximum length of the field, and each the size of a file may be from a few KBYTE to several GIGABYTE, if the format and other general information use the same kind of management style, easily lead to a waste of disk space and database performance is low, it must be used to separate the management of BLOB format. Gejia database vendors BLOB format and manner of storage capacity may not be the same, and some did not even BLOB format.
Blog
Blog is short for Web log. Is a personal log-style form of an article to share. Content is very diversified, from personal life experiences to the views of social events are not inevitable, genre writing is Xinshou mainly length may be longer or shorter, but are usually updated daily. Many Blog sites are also using the RSS technology, reader-friendly subscription.
Bluefin data storage software standard - blue fin
Bluefin more than a dozen technology companies around the world come together to develop a data storage software standard that will allow the different storage products easier to manage.
Including IBM, EMC, Hitachi, and Hewlett-Packard and other data storage manufacturers have supported the technology, while software companies, including Veritas, Brocade Communications Systems, and BMC have also joined the standard.
May be caused because in the past year, the data storage industry faces a reduction in IT spending, as well as EMC, IBM, and Hitachi and other makers of price wars and other problems caused not a small market shocks occur after the response of the Road.
Bluefin Due to the SAN to establish a common interface and control, it can be expected to improve the storage servers, tape drives, and switch management.
Bluetooth
Bluetooth is a short-range wireless transmission technology, mainly used in low-cost, low-power wireless personal area network interface (PAN) in the. Bluetooth is not only on a PC cable replacement, but also as a home, business or public places, data and voice transmission in the access point.
Bluetooth name of this technique has a very interesting origin. In the tenth century Norway, there was a Viking king named "‧ Harald Bluetooth" (Harald Bluetooth), because the unification of Denmark and leaving a legacy, a thousand years later, Ericsson marketers think they are a unified consumer electronic goods in the world can match the contributions paid by the king, and thus was born the name Bluetooth.
Bluetooth mainly in the 2.45 GHz frequency band operation, general information, but also is able to carry voice. Every Bluetooth technology to connect devices have developed under the IEEE 802 standard for 48-bit address; can be one-or multi-point connectivity, transmission range as far as 10 meters. Bluetooth technology not only transfer a large amount of per second up to 1MB, also can set the encryption to protect, and from electromagnetic interference.
Bluetooth technology allows mobile phones, computers, PDA and other handheld devices and home or on the company's telephone, computer connections, as long as the use of three-in models, we can integrate mobile phones, computers, PDA, and fax machines, and then link data transmission, printing equipment for home and office environment. However, all connected to the equipment must be installed on the transmission of a particular chip.
At present, more than 2000 manufacturers have to support Bluetooth wireless technology, including the Yi Li Shin (Ericsson), MOTO Laura (Motorola), Nokia (Nokia) and other telecom giants, as well as Intel, Microsoft, IBM, Toshiba and other major IT companies. |
