第 1 章 计算机系统概述1.1 操作系统的基本概念1.1.1 操作系统的概念、功能和目标
系统资源的管理者、提供接口、作为扩充机器、虚拟机
1.1.1.1 熟悉的操作系统举例
1.1.1.2 操作系统的层次结构
1.1.1.3 操作系统的概念
是系统最基本、最核心的软件，属于系统软件
控制和管理整个计算机的硬件和软件资源
合理的组织、调度计算机的工作与资源的分配
为用户和其它软件提供方便的接口和环境
1.1.1.4 操作系统的功能和目标
用一个直观的例子来理解上述图中操作系统的功能：
我们假设：用户是雇主，操作系统是工人（用来操作机器），计算机是机器（由处理机(CPU)、存储器、设备、文件几个部件构成）
工人有熟练的技能去控制和协调各个部件的工作，这就是操作系统对资源的管理
同时，工人必须接受雇主的命令，这就是“接口”
有了工人，机器就能发挥更大的作用，因此工人就成了“扩充机器”
工人操作机器、机器有了更大的作用比如GUI界面，于是工人便成了扩充机器，去扩充GUI界面等功能
（1）作为计算机系统资源的管理者
管理软硬件资源、合理的组织、调度计算机的工作与资源的分 ...</div></div></div><div class="recent-post-item"><div class="post_cover right"><a href="/2023/02/21/Vue2%E7%9A%84%E5%AD%A6%E4%B9%A0%E7%AC%94%E8%AE%B0/" title="Vue2的学习笔记"><img class="post_bg" src= "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-lazy-src="https://t1.tp88.net/uploads/allimg/2003/co200301223228-0.jpg" onerror="this.onerror=null;this.src='/img/2.jpg'" alt="Vue2的学习笔记"></a></div><div class="recent-post-info"><a class="article-title" href="/2023/02/21/Vue2%E7%9A%84%E5%AD%A6%E4%B9%A0%E7%AC%94%E8%AE%B0/" title="Vue2的学习笔记">Vue2的学习笔记</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">Created</span><time datetime="2023-02-20T16:54:08.000Z" title="Created 2023-02-21 00:54:08">2023-02-21</time></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/Vue/">Vue</a></span></div><div class="content">Vue2 学习笔记
1 Vue核心1.1 Vue简介1.1.1 官网
英文官网：https://vuejs.org/
中文官网：https://cn.vuejs.org/
1.1.2 简介
动态构建用户界面的渐进式JavaScript框架
1.1.3 Vue特点
采用组件化模式，提高代码复用率、且让代码更好维护
声明式编码，让编码人员无需直接操作DOM，提高开发效率
使用虚拟DOM+优秀的Diff算法,京可能复用节点
1.2 初始Vue1.2.1 小结
使用Vue
创建Vue实例，传入配置对象
容器内代码符合html规范
容器内代码称之为【Vue模板】
注意事项
Vue实例和容器一一对应
开发中Vue和组件配合使用
{{XXX}}中XXX写的是Js表达式，且XXX可以自动读取到data中的所有属性
data中的数据发生改变，页面中使用该数据的地方会自动更新
区分Js代码 && Js表达式
Js表达式：
一个表达式会产生一个值，可以放在任何一个需要值的地方
示例
a
a + b

判断奇数偶数：x&（与运算）1，如果等于1，则是奇数，为0则是偶数。
（与运算：& 符号通常表示按位与（bitwise AND）运算符。按位与运算是一种二进制运算，它对两个二进制数的每一位进行逻辑与操作，输出的结果为一个新的二进制数，其中每一位都是对应位上两个二进制数的与操作结果。例如，对于二进制数 1100 和 1010 进行按位与运算，结果为 1000，即 1100 & 1010 = 1000。
在某些编程语言中，& 符号也可以表示逻辑与（logical AND）运算符，逻辑与是指对两个逻辑表达式进行逻辑运算，只有两个表达式都为真时，输出结果才为真。例如，在C语言中，逻辑与运算符用 && 符号表示。）

如上图所示：
原码为1时，转换为二进制时为0000 0001 ，原码为-1时，在二进制的符号位（最前面的位数）上取1，为：1000 0001；1加上-1则为1000 0010，则原码是-2（符号位的1代表为负数）；
反码：当原码二进制的时候，是正数时，不需要取反，若是负数的时候，（只有符号位不变）剩下的全部取反（就是原来是0变为1，1变0），1-1可以看成1加上-1的二进制码，所以得到1111 1111，代表-0；
补码：当原码二进制的时候，是正数时，不需要取反，若是负数的时候，在原码的反码的基础上，个位数进1；
移码：就是补码的符号位取反；
原码，反码整数范围是一样的，补码为什么和他们不同，区别就在于0，反码和原码的0是表示为-0和+0，而补码则就是为0；当然，死记公式就行。

AJAX（Asynchronous Javascript And Xml）传统请求及缺点
传统的请求都有哪些？
直接在浏览器地址栏上输入URL。
点击超链接
提交form表单
使用JS代码发送请求

document.location.href = url
window.location.href = url
….
传统请求存在的问题- 页面全部刷新导致了用户的体验较差。- 传统的请求导致用户的体验有空白期。（用户的体验是不连贯的）
AJAX概述
AJAX不能称为一种技术，它是多种技术的综合产物。
AJAX可以让浏览器发送一种特殊的请求，这种请求可以是：异步的。
什么是异步，什么是同步？
假设有t1和t2线程，t1和t2线程并发，就是异步。
假设有t1和t2线程，t2在执行的时候，必须等待t1线程执行到某个位置之后t2才能执行，那么t2在等t1，显然他们是排队的，排队的就是同步。
AJAX是可以发送异步请求的。也就是说，在同一个浏览器页面当中，可以发送多个ajax请求，这些ajax请求之间不 ...</div></div></div><div class="recent-post-item"><div class="post_cover left"><a href="/2023/01/19/Filter/" title="Filter"><img class="post_bg" src= "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-lazy-src="https://t1.tp88.net/uploads/allimg/2003/co200301223228-0.jpg" onerror="this.onerror=null;this.src='/img/2.jpg'" alt="Filter"></a></div><div class="recent-post-info"><a class="article-title" href="/2023/01/19/Filter/" title="Filter">Filter</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">Created</span><time datetime="2023-01-19T10:09:50.000Z" title="Created 2023-01-19 18:09:50">2023-01-19</time></span></div><div class="content">Filter过滤器
