networks has become a high-speed access method that attracts more and more industry attention. Cable-Modem connections can be divided into two types: symmetric rate type and asymmetric rate type. The data upload speed is the same as the data download speed, both between kbps-2mbps; the latter data upload speed is between kbps-10mbps, and the data download speed is 2 mbps-40mbps. Because of the use of the shared structure, as users increase, the

With the development of cable TV networks and the continuous improvement of people's quality of life, using CableModem to access the Internet through cable TV networks has become a high-speed access method that attracts more and more industry attention. Cable-Modem connections can be divided into two types: symmetri

Mbps, Mbit/s, MB/s common sense literacyEasy to confuse several concepts: Mbps, MB/s, MB/s.1, we often hear that such IDC provides server access bandwidth is 10M exclusive, or 100M sharing and other data. What is the concept of 10M and 100M here?The so-called 10M bandwidth, in fact, refers to 10Mbps (megabits), that is, 1.25mb/s, but this is only the theoretical speed, in fact, but also minus the loss. According to this argument, the fastest download

occurs, the computer involved in the conflict will be sent back to the listening channel state.Note: Each computer is allowed to send only one packet at a time, a congestion sequence to warn all nodes)4. If no conflict is found, sending succeeds, all computers must wait 9.6 microseconds (running at 10Mbps) after the most recent send before attempting to send data again.2. Frame formatThere are four different frame formats for Ethernet, but there are

network that connects the local area network, is "Network Network" (Network between networks). 3. Metropolitan Area NetworkSince the development of computer network, according to geographical scope, can be divided into: LAN, metropolitan area network, WAN. The local area network is divided into the shared medium LAN and the switched LAN according to the media access control method, divided into the wired medium local area network and the wireless medium local area network according to the tran

How many cores does the server have? Are there some CPU cores that are overloaded? Where does the server's maximum load come from? What is the average load? Vii

PWR: Light indicates that the DC5V power adapter is working properly;FX 100: Light indicates a fiber transfer rate of 100Mbps;FX Link/act: Steady light indicates that the fiber link is connected correctly; The light shining indicates that there is data in the transmission of the fiber;FDX: Light indicates that the optical fiber transmits data in full duplex mode;TX 100: Light indicates a twisted pair transmission rate of 100Mbps;the lamp is not bright indicates the twisted pair transmission rate

maintain the transmission rate of 1000Mbps, RGMII interface in the rising edge of the clock and the falling edge are sampled data. On the rising edge of the reference clock, send the txd[3:0]/rxd[3:0] in the Gmii interface, sending txd[7:4]/rxd[7:4 in the Gmii interface on the falling edge of the reference clock]. The RGMII is compatible with two rates of 100Mbps and 10Mbps, at which point the reference clock rate is 25MHz and 2.5MHz respectively.Fig

dedicated to data storage. With the development of IP network technology, network access Storage (NAS) technology has undergone a qualitative leap. The 10Mbps bandwidth of the late 80 to the early 90, network access storage as a file server storage, performance is affected by bandwidth, and later the emergence of Fast Ethernet (100Mbps), VLAN virtual network, Trunk (Ethernet Channel) Ethernet channel, The read and write performance of the network acc

the following characteristics:(1) This network structure is generally only applicable to the IEEE 802.5 token network (Token Ring network), in which the "token" is transmitted sequentially in a ring-type connection. The use ofthe transmission medium is usually coaxial cable. (2) This kind of network realization is also very simple, the investment is minimal. Can be seen from its network structure, in addition to the network of workstations is the transmission medium-coaxial cable, andSome conne

download speed can have 10MBps (that is, 100Mbps). Note that the download speed is said here. Stillthere is a noun called the uplink speed, please know. two, intuitive method:1, 10 IP at the beginning is the intranet IP. That is, 10.0.0.0 to 10.255.255.255 is the intranet IP. A lot of home-pulled bandwidth routing is assigned to 10 IP, which is the network IP. 2, the address of the following IP segment is the intranet IP address. (1) 10.0.0.0 to 10.2

MPEG-2 as a compatible extension of MPEG-1, it supports interlaced video formats and many advanced features including support for multi-layered adjustable video encoding for a wide range of quality, such as multiple speeds and multiple resolutions. It is suitable for real-time images with large motion change, which require high image quality. 30 frames per second, 720*572 resolution video signal compression, data rate of up to 3-

The scientists of MPEG organization began to study the video compression method which is suitable for playing on the network, that is,

Network server bandwidth Mbps, MB/s, MB/s differenceThe meaning of MB/s is megabytes per second, MB/s means megabits per second, the former refers to the number of bytes transmitted per second, the latter refers to the number of bits transmitted per second. The two are completely different.The so-called 10M bandwidth, in fact, refers to 10Mbps (megabits)Computational bandwidth theory fastest download speed: 10÷8=1.25mb/sThe fastest download speed for
