lossless because the human ear cannot distinguish between a CD recording and a properly encoded MP3 version of it. MP3s achieve this transparency at a bit rate of approximately 256 kilobits per second, or roughly one sixth of the 1.4 megabits per second required by the compact disc format. MP3s can be recorded at lower bit rates, saving even more space, but audible differences begin to appear at rates

that the eth0 outlet has 100mbit/s bandwidth, assigned to WWW, e-mail and Telnet three data traffic, which is allocated to the WWW bandwidth of 40mbit/s, the bandwidth allocated to the email is 40mbit/s, the bandwidth allocated to Telnet is 20Mbit SIt is important to note that the following abbreviations are used in the TC to indicate the appropriate bandwidth:Kbps kiiobytes per second, or "kilobytes per second;Mbps megabytes per second, or "megabyte/sec,Kbit

Create an HTB queue The TC commands related to the queue are generally in the form: 1. # tc qdisc [add | change | replace | link] dev [parent qdisk-id | Root] [handle qdisc-id] qdisc [qdisc specific parameters] First, configure an HTB queue for et

For a category, its major must be the same as its parent category or the major of its parent queue, minor must be unique within a queue (because the category must be included in a queue ). For example, if Queue 2 contains two classes, the handles of these two classes must be in the form of 2: x, and their x cannot be the sam

For example, if queue 2 contains two classes, the handles of these two classes must be in the form of 2: x, and their x cannot be the same, such as and. Next, we will describe the use of TC based on the requirements of the HTB queue. Assume that the eth0 egress has a bandwidth of 100 mbit/s and is allocated to WWW, email, a

people have misunderstood "480mbps" as 480 megabits per second. In fact, this is wrong, in fact "480mbps" should be "480 megabits per second" or "480 megabits per second", it equals "60 megabytes per second", we see the gap.This starts with bit and byte: The bit and byte are translated as "bits", which are data measurement units, bit= "bit" or "bit".The byte= by

South Korean researchers have built a network router consisting of an end-to-end computer component that can transmit data at record speeds. The router, created by the Korean Academy of Advanced Science and technology, is transmitting data at a speed of 40,000 megabits per second (gigabits), many times faster than the previous record for similar devices. The technology that researchers use may lead to breakthroughs in many ways, including the use of i

It was not long before TCP/IP was present, and the proposal received suspicions from the National Science Foundation of the United States. But traffic explains everything (this network is growing in the form of explosions!) ), thanks to the TCP/IP protocol.They then entered the next phase, DS3, with a 30 times-fold increase in network design (compared to 1.5

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.
