A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board, or colloquially, a mobo) is a printed circuit board (PCB) found in all modern computers which holds many of the crucial components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals.

序列号就是软件开发商给软件的一个识别码，和人的身份证号码类似，其作用主要是为了防止自己的软件被用户盗用。用户要使用其软件就必须知道序列号。在用户注册的时候会根据用户软件所安装的计算机软硬件信息生成唯一的识别码，一般称作机器码，也叫序列号、认证码、注册申请码等。

主板，又叫主机板、系统板或母板；它安装在机箱内，是微机最基本的也是最重要的部件之一。 主板一般为矩形电路板，上面安装了组成计算机的主要电路系统，一般有BIOS芯片、I/O控制芯片、键盘和面板控制开关接口、指示灯插接件、扩充插槽、主板及插卡的直流电源供电接插件等元件。

A modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information.

调制解调器，是一种计算机硬件，它能把计算机的数字信号翻译成可沿普通电话线传送的脉冲信号，而这些脉冲信号又可被线路另一端的另一个调制解调器接收，并译成计算机可懂的语言。这一简单过程完成了两台计算机间的通信。

A binary tree is a tree data structure in which each node has at most two child nodes, usually distinguished as "left" and "right".

在计算机科学中，二叉树是每个结点最多有两个子树的有序树。通常子树的根被称作“左子树”和“右子树”。二叉树常被用作二叉查找树和二叉堆或是二叉排序树。二叉树的每个结点至多只有二棵子树(不存在度大于2的结点)，二叉树的子树有左右之分，次序不能颠倒。二叉树的第i层至多有2的 i -1次方个结点；深度为k的二叉树至多有2^(k) -1个结点；对任何一棵二叉树T，如果其终端结点数(即叶子结点数)为n0，度为2的结点数为n2，则n0 = n2 + 1。

Dynamic bandwidth allocation is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth.

动态带宽分配(DBA)是一种能在微秒或毫秒级的时间间隔内完成对上行带宽的动态分配的机制，EPON的DBA设置是针对每个ONU的上行流量，GPON可以更细致。同时DBA可以提高PON端口的上行线路带宽利用率；可以在PON口上增加更多的用户；用户可以享受到更高带宽的服务，特别是那些对带宽突变比较大的业务。
