unique acceleration methods. For example, Buffalo's 125 Mbps AfterBurner and 125 * High Speed Mode, D-Link DI-624 + Speed Enhanced Mode, and Cisco Linksys WRT54GS's Speed Booster. What is the performance of the non-standard 11g speed-up mechanism? It has been tested to be ups and downs. We simulate two commonly used topologies. For WLAN-LAN connections and WLAN-WAN connections, we opened the fastest speed-up feature supported by the products under te

or a limited geographical area. The Wan runs beyond the geographical range of the LAN, it uses data exchange networks of telecom operators to achieve connections in larger regions. The broadband network we usually call is generally used for wide area networks. The broadband network can be divided into two parts: the broadband backbone network and the access network. The data rate of the early broadband backbone network is above 2 m, and the data rate of the access network is above kbps, the dat

. That is, using a pair of copper wires in parallel, Internet access and phone calls can be achieved. As an independent broadband network local device, the V5924 switch provides Four 10/100 Mbps self-switching Ethernet ports (two 100 Mbps FX optical ports can be selected. Based on the combination of super virtual dedicated Ethernet devices, SDH, PDH, and DDN transmission channels can also be integrated for

lowercase English letter B), and 1Byte is abbreviated to 1B (note that it is a capital English letter B ).Generally, in a computer network or network operator, the unit of bandwidth rate is expressed in bps (or B/s); bps indicates the number of bits per second (that is, the number of bits transmitted per second, it is the abbreviation of bit per second. In practice, 1 Mbps bandwidth means 1 Mbps (1

1. Description of byte and bit In computer science, bit is the smallest unit of information, which is called a binary bit. It is usually represented by 0 and 1. Byte is called a byte. It consists of eight (8 bit) bytes (1 byte), used to represent a character in the computer. Bit and byte can be converted. The conversion relationship is 1 byte = 8bit (or 1B = 8b, that is, 1bit is abbreviated to 1B (note that it is a lowercase English letter B), and 1byte is abbreviated to 1B (note that it is a ca

With the development of the network, wireless networks have been recognized by more and more users by virtue of the free and fast features, especially the 802.11n Technology (hereinafter referred to as 11n), with a connection rate of Mbps, this allows hundreds of megabytes of access over Ethernet, and supports a wide range of high-quality multimedia applications.

and arbitrary-length data frames.IICUnlike SPI's single-master device, IIC is a multi-master bus, IIC does not have a physical chip selection signal line, no quorum logic circuit, only two signal lines are used-' serial data ' (SDA) and ' Serial Clock ' (SCL). The IIC agreement stipulates that:§ First, each IIC equipment has a unique seven-bit device address;§ Second, the data frame size is 8 bits of bytes;§ Third, some data bits in the data (frame) are used to control the start, stop, directio

Bit indicates "bit" or "bit", which is the basis of computer computing and belongs to the binary model; Byte indicates "Byte", which is the basic unit for calculating the computer file size; The applications of the two are different. Bit is usually used as the unit of data transmission. Because of the physical layer, data link layer transmission is transparent to users, and such communication transmission is based on binary transmission. In the application layer, bytes are usually used as the

B), and 1byte is abbreviated to 1B (note that it is a capital English letter B ).Generally, in a computer network or network operator, the unit of bandwidth rate is expressed in BPS (or B/S); BPS indicates the number of bits per second (that is, the number of bits transmitted per second, it is the abbreviation of bit per second. In practice, 1 mbps bandwidth means 1 Mbps (1

Test oracle db iops Today, I need to test one database's iops and do something for oracle db's io test. How to test the db's iops? It can use oracle's pl/SQL package taht is dbms_resource_manager.calibrate_io. here is the introduction of that procedure. CALIBRATE_IO ProcedureThis procedure calibrates the I/O capabilities of storage. calibration status is available from theV $ IO_CALIBRATION_STATUS view and results for a successful calibration run are located inDBA_RSRC_IO_CALIBRATE table.

transmitted per unit time (in bytes, kilobytes, or megabytes );Type 2: bps (or B/s), Kbps (or Kb/s), or Mbps (or Mb/s), indicating the unit time (SEC) the amount of data transmitted within (bits, kibits, and megabits ). The two bandwidth conversion formulas:1 Bps (B/s) = 8 bps (B/s)1 KBps (KB/s) = 8 Kbps (Kb/s)1 MBps (MB/s) = 8

access. The theoretical speed was 56Kb/s, and the download speed was 8 KB per second. In addition to bandwidth loss, the actual download speed was 7KB/s. Currently, a software is dozens of megabytes, and a large one is hundreds of megabytes or even several GB. Dialing is no longer enough. As Internet applications are increasingly abundant today, the demand for bandwidth has also changed. Currently, online

television Advantages: low cost and good service attitude. many foreign websites cannot be opened directly. Insufficient: bandwidth sharing, unstable network speed, slow peak periods, and no public IP addresses. 4. the features of other networks are the same as those of the 2 and 3 floors. 2. technical term answers Assume that 4 Mbps bandwidth is used and 4 Mbps of writing is used. 1. dedicated bandwidth a

housekeeping time (such as instruction processing), As the internal operation time is generally very short (generally around 0.2ms), negligible, so the average access time can be approximately equal to the mean seek time + average latency, and thus the average addressing time. If the average seek time for a 5400r/min hard disk is 9ms, then theoretically its average access time is 14.556ms. 10, data transmission rate (dtr,datatransferrate) The data transfer rate is per MB/s (
