子网掩码及其应用

by wu weixin | 8 months ago | Read more

　　在TCP/IP协议中，SUBNET MASKS（子网掩码）的作用是用来区分网络上的主机是否在同一网络取段内。在大型网络中，CLASS A的SUBNET MASKS为255.0.0.0， CLASS B的SUBNET MASKS为255.255.0.0，CLASS C的SUBNET MASKS为255.255.255.0。　　假如某台主机的SUBNET MASKS为IP地址为202.119.115.78，它的SUBNET MASKS为255.255.255.0。将这两个数据作AND运算后，所得出的值中的非0的BYTE部分即为NETWORK ID 。运算步骤如下：　　202.119.115.78的二进制值为：　　11001010.01110111.01110011.01001110　　255.255.255.0的二进制值为:　　11111111.11111111.11111111.00000000　　AND后的结果为： 　　　11001010.01110111.01110011.00000000　　转为二进制后即为：　　202.119.115.0　　它就是NETWORK ID，在IP地址中剩下的即为HOST ID，即为78，这样当有另一台主机 　的IP 地址为202.119.115.83，它的SUBNET MASKS也是255.255.255.0，则其NETWORK ID 　为202.119.115，HOST ID为83，因为这两台主机的NETWORK ID都是202.119.115，因此，这两台主机在同一网段内。　　但是，在实际应用中，可能会有多个分布与各地的网络，而且，每个网络的主机数量并不很多，如果申请多个NETWORK ID，会造成IP资源的浪费，而且很不经济，如果我们在SUBNET MASKS上动一下手脚，可以在只申请一个NETWORK ID的基础上解决这个问题。　　比如，我们有三个不同的子网，每个网络的 HOST数量各为20、25和50，下面依次称为甲、乙和丙网，但只申请了一个NETWORK ID 就是202.119.115。首先我们把甲和乙网的SUBNET MASKS改为255.255.255.224，224的二进制为11100000，即它的SUBNET MASKS为：　　11111111.11111111.11111111.11100000　　这样，我们把HOST ID的高三位用来分割子网，这三位共有000、001、010、011、100、 101、110、111八种组合，除去000（代表本身）和111（代表广播），还有六个组合，也就是可提供六个子网，它们的IP地址分别为：（前三个字节还是202.119.115）　　00100001~00111110 即33~62为第一个子网　　01000001~01011110 即65~94为第二个子网　　01100001~01111110 即97~126为第三个子网 　　　10000001~10011110 即129~158为第四个子网 　　　10100001~10111110 即161~190为第五个子网 　　　11000001~11011110 即193~222为第六个子网　　选用161~190段给甲网，193~222段给乙网，因为各个子网都支持30台主机，足以应付甲网和乙网20台和25台的需求。　　再来看丙网，由于丙网有50台主机，按上述分割方法无法满足它的IP需求，我们 可以将它的SUBNET MASKS设为255.255.255.192， 由于192的二进制值为11000000，按上述方法，它可以划分为两个子网，IP地址为：　　01000001~01111110 即65~126为第一个子网 　　　10000001~10111110 即129~190为第二个子网　　这样每个子网有62个IP可用，将65~126分配丙网，多个子网用一个NETWORK ID 即告实现。　　如果将子网掩码设置过大，也就是说子网范围扩大。那么根据子网寻径规则，很可能发往和本地机不在同一子网内的目的机的数据，会因为错误的相与结果而认为是在同一子网内，那么，数据包将在本子网内循环，直到超时并抛弃。数据不能正确到达目的机，导致网络传输错误。如果将子网掩码设置得过小，那么就会将本来属于同一子网内的机器之间的通信当做是跨子网传输，数据包都交给缺省网关处理，这样势必增加缺省网关的负担，造成网络效率下降。因此，任意设置子网掩码是不对的，应该根据网络管理部门的规定进行设置。　　随着IP地址资源的日趋枯竭，可供分配的IP地址越来越少，往往一个拥 有几百台计算机规模的网络只能得到区区几个IP地址，于是，许多人开始采用其他技术来扩展IP空间。　　1.子网掩码设置　　如果你所分配的IP地址仅能满足对主机的需求，但远不能满足你欲在局 域网中再建若干子网的需要，设置子网掩码就是你不得不采取的措施了。　　子网掩码同样也以四个字节来表示，用来区分IP地址的网络号和主机号， 默认子网掩码如下表所示：　　子网掩码(以十进制表示)　　A类 255．0．0．0　　B类 255．255．0．0　　C类 [...]

幼儿期（3～6岁）

by wu weixin | 8 months ago | Read more

[b][color=Purple]幼儿期（3～6岁） 3岁以后脑的发展渐缓，到六七岁时脑重量接近成人水平，约1280克，为成人脑重量的90%。 语言的发展 此时期词汇量增长最快，6岁时可达3000~4000个。幼儿基本上掌握了各种语法结构，但对结构复杂的句子还不能完全理解意思，语言表达逐渐由连贯性语言取代情境性语言。此时，家长应充分利用机会与儿童交谈，发展其语言能力。 思维和想象能力的发展 幼儿在游戏中扮演不同角色，并且根据角色的身分进行表演，学做妈妈给孩子喂食，扮作者师教学生，扮演医生给病人看病等。这个时期的儿童思维还不能离开事物的具体形象，思维具有直觉性，往往只根据事物外在的表象作出判断。 幼儿已具有丰富的想象力，这表现在他们的游戏、绘画、手工、讲故事等活动中。日常所见所闻是他们创作的源泉，他们会模仿成人学开汽车，学打仗游戏、玩过家家……。随着年龄增长，这些活动的目的性、创造性也相应增强。幼儿园开展多方面的活动，有助于儿童思维能力的发展。幼儿园大班时，要求儿童重述故事的内容，记住生字，这些要求能促使幼儿有意记忆能力的发展。 情绪和社会性的发展 幼儿的情绪已相当丰富，而且十分容易表现出来，不太稳定，缺少控制，通常对鬼怪、运动以及黑暗等有恐惧心理。此时，已开始发展如道德、理智等一些较高级的情感，能遵守一般行为规范。幼儿好奇好问，还喜欢拆装玩具、器物，进行探究。 5岁后，知道自己是男孩或女孩，并有认同感。自我意识有所发展。一直受到周围人肯定、积极评价的儿童会比较自信；而经常受到否定、消极评价的儿童则容易产生自卑感、孤独感。这些脾气、性格、情绪、行为的特别表现，心理学上称为个性心理特征和个性倾向性，常是一个人个性的核心。已形成的行为定式是很难改变的，因此，应特别注意幼儿期的个性教育。这时期形成的个性性格倾向，虽然尚未成熟，但对今后心理发展有深远影响，俗话说，“三岁看到老”，说的就是这个意思。[/color][/b] 你有可能感兴趣的其他文章： 如何让老板舍不得你 PHP 中 Router 类的实现 一张软盘的linux系统BabyLinux 最容易损坏机器的小动作! 网站服务器通用和专用保护方法比较分析

跟我学编程系列

by wu weixin | 11 months ago | Read more

发现大部分黑白的朋友都不会编程, 这可不是件好事, 所以这次我就写了一个简单的编程教程, 讲一下VBScript. 主要面向菜鸟, 懂得编程的朋友就不要浪费时间了, 如果你想接触以下VBScript也可以, 但既然有编程基础推荐直接去找一些参考书来读, 会比较快. 什么是VBScript呢? VBScript的全称是:Microsoft Visual Basic Script Editon.(微软公司可视化BASIC脚本版). 正如其字面所透露的信息, VBS(VBScript的进一步简写)是基于Visual Basic的脚本语言. 我进一步解释一下, Microsoft Visual Basic是微软公司出品的一套可视化编程工具, 语法基于Basic. 脚本语言, 就是不编译成二进制文件, 直接由宿主(host)解释源代码并执行, 简单点说就是你写的程序不需要编译成.exe, 而是直接给用户发送.vbs的源程序, 用户就能执行了.　　我知道菜鸟现在最关心的就是用什么工具来开发VBS程序了, 答案是:记事本(Notepad).我不是开玩笑, 其实任何一种文本编辑器都可以用来开发VBS开发, 只不过记事本是由系统自带的, 比较好找而已. 尽管如此, 我还是建议你去下载一个专业的文本编辑器, 因为这些工具可以提供 “语法高亮”等功能, 更加方便开发, 用哪一个随你喜好, 我比较喜欢Edit Plus (2.10). 　　OK, 我们先来写一个VBScript程序热热身.REM 输入并回显你的名字‘使用InputBox和Msgbox函数Dim name,msgmsg=”请输入你的名字:” name=Inputbox(msg,”名称”) Msgbox(name)　　把上面的程序清单输入到记事本里面, 然后保存为以.vbs为扩展名的文件(”保存类型”里面选择”所有文件”).然后双击运行, 观察运行结果. 注意:请自己输入程序清单, 不要复制->粘贴!　　我来解释一下这个程序, [...]

Eye tracking

by Jon Baer | over 2 years ago | Read more

Eye tracking:

Eye tracking is the process of measuring either the point of gaze (“where we are looking”) or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the visual system, in psychology, in cognitive linguistics and in product design. There are a number of methods for measuring eye movement. The most popular variant uses video images from which the eye position is extracted. Other methods use search coils or are based on the electrooculogram.

Qt прикрутить к Netbeas

by Ruslan Voloshin | over 2 years ago | Read more

Помогите решить проблему новичку в общем выбрал пока IDE Netbeas и решил узнать как в Руби создаётся графический интерфейс , решил скачать Qt установил всё по умолчанию .
Дальше создаю проект , пишу код самой простой формочки окна нажимаю Run Ide не выдаёт не одной ошибки , а просто показывает адрес где сохранён проект.
Хотя по идеи на экране должно появится моё созданое окошко , как я делал точно также как и в Python Netbeas +TK только для питона я ТК не скачивал так как оно там уже идёт в стандартной упаковке.
По началу у меня и в Python были проблемы с созданием интерфейса , но потом я заметил когда создаётся новый проект в NetBeas там придлогаетца выбрать платформу внизу Python либо JPython я этого не когда не замечал так как с кодом проблем не когда не было ну решил выбрать Python и вуаля моё окошко сразу высветилось !
В Ruby платформа стоит только JRuby и я думаю вся проблема в этом не подскажите как решить проблему ??
Может переустановить NetBes либо как то по хитрому устанавливать Qt

И еще вопрос какими пакетами пользуетесь вы для создания графического интерфейса и чтоб с доками желательно на русском , на ТК много доков но что то все на него плюются говорят то там не работает то там ??
может есть что поинтересней но с Qt все ровно помогите :))
