该软件会在用户的使用过程中自动进行调整达到最佳状态，特别是对于使用bt等p2p软件的用户，基本不需要进行手工调较。下面是引自VeryCD的手工调较步骤
(1) 待测 ADSL 网络净空, 也就是没有任何计算机使用到频宽
(2) 确定打开 信息通信量调整 功能.
(3) 右键任务栏 cFos/cFosSpeed 执行 (删除关于线路的数据)
(4) 纯粹全速下载!! 最好的方法就是找个大档案下载 (千万别用 P2P, 因为会动到大量上传), 这样的过程建议超过 30 秒. 然后停止下载.
(5) 纯粹全速上传!! 最好方式, 就是发一封 eMail, 夹个大档案 (建议超过 5MB) 给自己, 但也不用真的把这封信传完, 只要能保持全速上传约 60 秒就可以了.
-the software users in the process of using automatic adjustments to achieve the best condition, particularly for the use of such bt p2p software users do not need basic manual adjustments. Below is a quote from VeryCD manual adjustment steps (1) the unknown ADSL network headroom. is no use of computer bandwidth (2) identify information and communication open adjust function. (3) right-click the task bar cFos / cFosSpeed implementation (to remove the lines of data) ( 4) simply download full swing! ! The best way is to find a download large files (Do not use P2P. because it will move a large number of uploading), Such a process recommended more than 30 seconds. then stop downloading. (5) exclusively at full speed uploads! ! the best way eMail is a fat folder large files (over 5MB recommended Platform: |

Description: Up until the end of the 20th century, there was a fairly clear division between the cellular industry and other telecommunication
industries which offered basic telephone, television, radio, computer and Internet services. Most mobile operators used
second generation (2G) digital wireless technologies to enable voice communications and limited data services, while most
wireline, cable and satellite systems provided the bulk of the other telecommunication services. In spite of its initial limitations,
cellular communications have been a tremendous success, surpassing fixed line connections worldwide in 2001, just 12
years after its market introduction. This has been especially evident in developing markets where, due to their lower
deployment costs and greater network flexibility, wireless technologies have become the primary means of communication
for millions of people, spurring the economic and social development of these markets. Platform: |

Description: 随着多微机系统的应用和微机网络的发展，通信功能越来越显得重要。串行通信是在一根传输线上一位一位地传送信息.这根线既作数据线又作联络线。串行通信作为一种主要的通信方式，由于所用的传输线少，并且可以借助现存的电话网进行信息传送，因此特别适合于远距离传送。在串行传输中，通信双方都按通信协议进行，所谓通信协议是指通信双方的一种约定。约定对数据格式、同步方式、传送速度、传送步骤、纠错方式以及控制字符定义等问题做出统一规定，通信双方必须共同遵守。-With the application of multi-microcomputer systems and computer networks, communication becomes less important. Serial communication is a one in a transmission line to transmit information, which lines both for the data line and make contact line. Serial communication as a primary means of communication, since the transmission line with less, and can make use of existing telephone network for information transmission, it is particularly suitable for long-distance transmission. In serial transmission, the communication protocol for communication by both sides, the so-called communication protocol is an agreement the two sides. Agreement on data formats, synchronization, transmission speed, transmission procedures, error correction, and control characters are defined to make uniform provisions and other issues, communication, both parties must abide by.
