大家了解一下电脑知识（Everyone knows something about computers）

大家了解一下电脑知识（Everyone knows something about computers） Everyone knows something about computers At present, most broadband users dont know much about their bandwidth: 1. think oneself is 2M broadband, download speed can reach 2M/s. (answer: 2M unit is BPs, file unit is B, 8bps = 1b, so 2M traffic, converted to download speed, that is, 256Kb/s, not 2Mb/s, pay attention to units) 2. see your computer in the lower right corner of the display is 100Mbps, think of themselves as 100Mbps broadband network. (answer: 100Mbps is the maximum flow velocity, the card is not the users real speed, the real speed is controlled by the telecom household users) 3. Telecom said to you District 10M broadband, you can think of their own exclusive 10M bandwidth is small. (answer: the so-called broadband, refers to a small, broadband 10M bus, for all the district users. Each user cannot allocate a fixed flow. So but there is a user with 1M/s the speed of downloading files, then the rest of all speeds are only very low bandwidth, basically can only browse the web, not normal to play games, challenge and delay in basic 1000ms above) 4. telecommunications network and Netcom network are 2 separate lines, access to each other will have a very high latency. Therefore, it is recommended that telecom users into the telecom server, Netcom users into Netcom server 5., general 2M ADSL download speed can be stabilized at around 240Kb/s 6. that the fiber is faster than ADSL. (answer: only in the optical fiber data transmission mode is different, and the ADSL cable is used in copper, more than 10M high speed data transmission network, packet loss is serious, the highest can only reach 10M, and the highest speed fiber almost unlimited, it can reach 100M or more the transmission speed, 100M is the Internet standard speed. But to make it clear that the same 8M ADSL and optical fiber, the speed difference can be neglected. The only drawback is that.ADSL can do faster, but we present the basic speed in 1M - 2M
