5 | CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
6 | LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
7 | ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
8 | INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
9 | REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
10 | PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
11 | THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
12 | HEREUNDER.
13 |
14 | Statement of Purpose
15 |
16 | The laws of most jurisdictions throughout the world automatically confer
17 | exclusive Copyright and Related Rights (defined below) upon the creator
18 | and subsequent owner(s) (each and all, an "owner") of an original work of
19 | authorship and/or a database (each, a "Work").
20 |
21 | Certain owners wish to permanently relinquish those rights to a Work for
22 | the purpose of contributing to a commons of creative, cultural and
23 | scientific works ("Commons") that the public can reliably and without fear
24 | of later claims of infringement build upon, modify, incorporate in other
25 | works, reuse and redistribute as freely as possible in any form whatsoever
26 | and for any purposes, including without limitation commercial purposes.
27 | These owners may contribute to the Commons to promote the ideal of a free
28 | culture and the further production of creative, cultural and scientific
29 | works, or to gain reputation or greater distribution for their Work in
30 | part through the use and efforts of others.
31 |
32 | For these and/or other purposes and motivations, and without any
33 | expectation of additional consideration or compensation, the person
34 | associating CC0 with a Work (the "Affirmer"), to the extent that he or she
35 | is an owner of Copyright and Related Rights in the Work, voluntarily
36 | elects to apply CC0 to the Work and publicly distribute the Work under its
37 | terms, with knowledge of his or her Copyright and Related Rights in the
38 | Work and the meaning and intended legal effect of CC0 on those rights.
39 |
40 | 1. Copyright and Related Rights. A Work made available under CC0 may be
41 | protected by copyright and related or neighboring rights ("Copyright and
42 | Related Rights"). Copyright and Related Rights include, but are not
43 | limited to, the following:
44 |
45 | i. the right to reproduce, adapt, distribute, perform, display,
46 | communicate, and translate a Work;
47 | ii. moral rights retained by the original author(s) and/or performer(s);
48 | iii. publicity and privacy rights pertaining to a person's image or
49 | likeness depicted in a Work;
50 | iv. rights protecting against unfair competition in regards to a Work,
51 | subject to the limitations in paragraph 4(a), below;
52 | v. rights protecting the extraction, dissemination, use and reuse of data
53 | in a Work;
54 | vi. database rights (such as those arising under Directive 96/9/EC of the
55 | European Parliament and of the Council of 11 March 1996 on the legal
56 | protection of databases, and under any national implementation
57 | thereof, including any amended or successor version of such
58 | directive); and
59 | vii. other similar, equivalent or corresponding rights throughout the
60 | world based on applicable law or treaty, and any national
61 | implementations thereof.
62 |
63 | 2. Waiver. To the greatest extent permitted by, but not in contravention
64 | of, applicable law, Affirmer hereby overtly, fully, permanently,
65 | irrevocably and unconditionally waives, abandons, and surrenders all of
66 | Affirmer's Copyright and Related Rights and associated claims and causes
67 | of action, whether now known or unknown (including existing as well as
68 | future claims and causes of action), in the Work (i) in all territories
69 | worldwide, (ii) for the maximum duration provided by applicable law or
70 | treaty (including future time extensions), (iii) in any current or future
71 | medium and for any number of copies, and (iv) for any purpose whatsoever,
72 | including without limitation commercial, advertising or promotional
73 | purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
74 | member of the public at large and to the detriment of Affirmer's heirs and
75 | successors, fully intending that such Waiver shall not be subject to
76 | revocation, rescission, cancellation, termination, or any other legal or
77 | equitable action to disrupt the quiet enjoyment of the Work by the public
78 | as contemplated by Affirmer's express Statement of Purpose.
79 |
80 | 3. Public License Fallback. Should any part of the Waiver for any reason
81 | be judged legally invalid or ineffective under applicable law, then the
82 | Waiver shall be preserved to the maximum extent permitted taking into
83 | account Affirmer's express Statement of Purpose. In addition, to the
84 | extent the Waiver is so judged Affirmer hereby grants to each affected
85 | person a royalty-free, non transferable, non sublicensable, non exclusive,
86 | irrevocable and unconditional license to exercise Affirmer's Copyright and
87 | Related Rights in the Work (i) in all territories worldwide, (ii) for the
88 | maximum duration provided by applicable law or treaty (including future
89 | time extensions), (iii) in any current or future medium and for any number
90 | of copies, and (iv) for any purpose whatsoever, including without
91 | limitation commercial, advertising or promotional purposes (the
92 | "License"). The License shall be deemed effective as of the date CC0 was
93 | applied by Affirmer to the Work. Should any part of the License for any
94 | reason be judged legally invalid or ineffective under applicable law, such
95 | partial invalidity or ineffectiveness shall not invalidate the remainder
96 | of the License, and in such case Affirmer hereby affirms that he or she
97 | will not (i) exercise any of his or her remaining Copyright and Related
98 | Rights in the Work or (ii) assert any associated claims and causes of
99 | action with respect to the Work, in either case contrary to Affirmer's
100 | express Statement of Purpose.
101 |
102 | 4. Limitations and Disclaimers.
103 |
104 | a. No trademark or patent rights held by Affirmer are waived, abandoned,
105 | surrendered, licensed or otherwise affected by this document.
106 | b. Affirmer offers the Work as-is and makes no representations or
107 | warranties of any kind concerning the Work, express, implied,
108 | statutory or otherwise, including without limitation warranties of
109 | title, merchantability, fitness for a particular purpose, non
110 | infringement, or the absence of latent or other defects, accuracy, or
111 | the present or absence of errors, whether or not discoverable, all to
112 | the greatest extent permissible under applicable law.
113 | c. Affirmer disclaims responsibility for clearing rights of other persons
114 | that may apply to the Work or any use thereof, including without
115 | limitation any person's Copyright and Related Rights in the Work.
116 | Further, Affirmer disclaims responsibility for obtaining any necessary
117 | consents, permissions or other rights required for any use of the
118 | Work.
119 | d. Affirmer understands and acknowledges that Creative Commons is not a
120 | party to this document and has no duty or obligation with respect to
121 | this CC0 or use of the Work.

37 | # 计算机组织和体系结构/组成原理
38 | 学分最多的一集，千万要谨记这门课5.5学分。我的老师其实没啥大问题，就是经常补课，而且讲的比较慢。
39 |
40 | 内容是真他妈多。
41 |
42 | 23年期中考，主要内容是前四章Cache之前的内容（西电教材），主要侧重原码、反码、补码、移码这些，然后是原码乘法、补码乘法，以及除法。 期中考的内容个人感觉不难。
43 |
44 | 23年期末考最新资讯：选择15题（没啥奇怪的题）；大题第一题主存虚存以及Cache的相关计算，送分的;第二题有一个双总线结构的CPU的题，第一问考相容性和互斥性，第二问写微操作序列和微命令；第三问是一个水平型微指令写各个控制域字段的控制命令和位数；最后一题是关于流水线的，第一问就是正常的计算吞吐量和加速比，第二问是跳转的（其实我也不确定自己写的对不对，题目貌似没说是否断流，如果有分支预测啥的可能断流啥的）
45 |
46 | 6月23日补档，昨天晚上出的成绩总评92，期中94、期末92，实验89，算是符合预期吧（（整学期没听过课我个人觉得已经很不错了 5/109）。

51 | # 计算机网络
52 | 最逆天的一集。
53 |
54 | 生平第一次见到老师翘课，曾经创下一节课讲十章的神话，期中没考试问我们期中考的怎么样，甚至可以学到让步状语从句。（甚至多次登错成绩）
55 |
56 | 典型的上课耽误学习的例子。
57 |
58 | 23年6月13补档，期末考只有部分不太确定。趁着记忆，选择题10题（有一题802.11无线局域网定义在哪两层）；大题第一题是香农定理、信噪比相关的计算；第二题是CRC余数的计算；第三题是画Manchester码；第四题第一问考了最小帧长、第二问考了802.3的MAC层帧结构和功能、第三问考了填空（合适位置填入网桥、集线器、交换机、路由器、中继器）；第五题Dijkstra算法生成路由表；第六题IP地址分配；第七题TCP连接建立、数据传输、连接取消的图以及拥塞控制；第八题邮件系统，发送邮件的过程，UA的作用，MTA的作用；收发邮件有哪些协议；
59 |
60 | 6月23补档，期末考88，实验89.9（奇怪的数字）最后总评88（可以说这是从头到尾自学的一门课了，这样子知足了。最后排名3/71那只能说老师不够给力了）

66 | # 操作系统
67 | 这学期唯一正常的老师。
68 |
69 | 这门课还好（就考核而言），有点就是八股文，缺点也是如此，这就导致难以深入理解操作系统。
70 |
71 | 23年6月19补档，期末考刚结束，回忆一下跟往年不同的地方吧，首先选择题有一个FAT簇的分配问题，其他选择没啥特别的；大题的话，第一题是磁盘调度，考了个SCAN算法的，第二题死锁的资源图化简，第三题多级队列循环调度（这个点往年没考过），第四题银行家算法，第五题虚存相关内容、然后是缺页的置换算法LRU FIFO啥的，第六题是UNIX的文件打开的那题（稍微不同的是要求画出磁盘索引区），第七题多道程序的作业调度，计算平均周转时间和周转系数，细心即可。

18 |
19 | # 推荐书籍
20 | 首先是应试，肯定是学校的书（不买也行，因为我这学期压根没买西电的教材）
21 |
22 | 但是国内好教材真的很少，唐朔飞的《计算机组成原理》很不错；
23 |
24 | 然后可以参考传说中的CSAPP（当然这书什么都有，可以说是三大件的“简介”）
25 |
26 | 因为自学的时候莫名其妙钻研了一下补码/加上还玩魔方(魔方跟群论有关系)，所以学有余力可以看看群论（补码加法满足阿贝尔群）
27 |
28 | 然后直接看考研书
29 |
30 | # 指南
31 | 这门课真的很重要，学分比高数还高，而且信息差容易造成考试分数段的断崖（据说好多挂科的）
32 |
33 | # 实验
34 | 计组的实验就是用QuartusII模拟计算机的部分部件，说实话，给分还是得看老师（看命了）

25 |
26 | # 推荐书籍
27 | 西电用的是大黑书《数据通信与网络》这本书的特点是非常详细深入，但是也很难。
28 |
29 |
30 |
31 | 另外推荐《计算机网络：自顶向下法》
32 |
33 |
34 |
35 | 如果你老师很烂，你直接拿本考研书来看就行。
36 |
37 |
38 |
39 | # 指南
40 | 西电最后期末考的话，基本上都是偷考研题的。当然还有一些原创的题目（基本都是错题）
41 |
42 | 所以功利角度来说，想要高分，直接考研。
43 |
44 | # 思维导图
45 |
46 | ## 物理层和介质
47 |
48 |
49 | ## 数据链路层

59 |
60 |
61 | # 实验
62 | 课程实验也是一门玄学（从给分的角度），占比25%就看命吧，实验老师记不住人的。
63 |
64 | 但是这方面的实验都很简单。
65 |
66 | 主要内容有
67 |
68 | **网络基础知识及双绞线制作、访问网络设备实验**
69 |
70 | **交换机VLAN相关实验**
71 |
72 | **路由器基础配置实验**
73 |
74 | **静态路由和RIP路由配置**
75 |
76 | **Windows下DNS、DHCP服务器配置**
77 |
78 | **Windows下的WEB、FTP服务器配置**

18 | # 前言
19 | 这学期唯一正常的老师。
20 |
21 | 这门课还好（就考核而言），有点就是八股文，缺点也是如此，这就导致难以深入理解操作系统。
22 |
23 | 23年6月19补档，期末考刚结束，回忆一下跟往年不同的地方吧，首先选择题有一个FAT簇的分配问题，其他选择没啥特别的；大题的话，第一题是磁盘调度，考了个SCAN算法的，第二题死锁的资源图化简，第三题多级队列循环调度（这个点往年没考过），第四题银行家算法，第五题虚存相关内容、然后是缺页的置换算法LRU FIFO啥的，第六题是UNIX的文件打开的那题（稍微不同的是要求画出磁盘索引区），第七题多道程序的作业调度，计算平均周转时间和周转系数，细心即可。
