课程名称：《计算机网络的世界：您的CCNA从这里开始》 课程概述： 此课程由持有CCIE（Cisco认证互联网专家）证书的讲师教授，旨在深入探讨计算机网络的关键和重要特性。讲师拥有7年的Cisco认证系统讲师（CCSI）教学经验，曾亲自教授数百名学生。课程内容不包含过时的信息，注重实际应用。 通过本课程，您将理解计算机网络的工作原理，并学习关键的网络协议，包括以太网、IPv4、IPv6、TCP、UDP、NAT、DHCP、DNS以及私有和公共IP地址和子网划分。如果这些术语对您而言较为陌生，本课程将通过易懂的图示和多种实践活动帮助您掌握相关知识。您只需使用电脑和Wireshark软件即可分析不同的协议和TCP/IP层的头部信息，助您成为计算机网络的专家。 本课程是准备CCNA（Cisco认证网络助理）考试的理想起点。无论您是零基础还是有一定经验，课程将从基础到高级知识进行全面讲解，帮助您深入理解计算机网络。 课程内容将涵盖： - TCP/IP和OSI模型 - 物理层和数据链路层（以太网、MAC地址和交换机） - 网络层（路由、IPv4、IPv6、子网划分、网络掩码、IP地址、ARP、ICMP） - 传输层（TCP和UDP协议的详细讨论） - 应用层（DHCP和DNS协议的重要性） 您还将了解DNS的工作机制、路由器如何构建路由表并做出路由决策，以及BGP（全球路由协议）的相关内容。 实践部分将包括： - 安装Wireshark并使用其进行网络协议的分析 - 分析以太网头部 - 理解DHCP请求和响应如何帮助分配IP地址 - 分析IPv4头部结构，实践子网划分 - 探索无线路由器的IP、DHCP和NAT设置 - 使用nslookup工具进行DNS和反向DNS查询 通过几乎200节讲座和大量实践练习，您将获得终生访问权，完成课程后能够流利解释两个主机在互联网上通信的过程，并真正理解计算机网络的运作方式。课程还提供30天无条件退款保证。 不要犹豫，立即加入课程吧！
I have CCIE (Cisco Certified Internetwork Expert) certificate that is most recognisable Computer Network certification in the world and I know about Computer Networks a lot. In this course I share my knowledge about KEY and MOST IMPORTANT features of the Computer Networks. No obsolete info! Also I've taught hundreds of students in person in classes because during 7 years I was working as Cisco Certified Systems Instructor (CCSI).This course is all about Computer Networking and Internet. Understand HOW Computer Networks work and learn key Networking ProtocolsEthernet, IPv4, IPv6, TCP, UDP, NAT, DHCP, DNS, private and public IP addresses, subnettingIf those terms are new to you - jump in and you will learn all about them with help of multiple easy-to-grasp diagrams and using multiple practice activities. Most practice activities require just your computer and program called Wireshark.It helps to perform analysis of different protocols and TCP/IP layers headers.Become a master of Computer Networking!If you prepare for the CCNA (Cisco Certified Network Associate) exam, this course is a perfect start for you!This is the most complete Computer Networking Guide here on Udemy that includes tons of practical activities. You could have zero knowledge about Computer Networking. All will be taught from scratch, from basic to advanced features. If you want to get deep knowledge of Computer Networking this course is for you!We will start by taking about TCP/IP and OSI models. This knowledge is required in order to understand how different hosts communicate with each other and that all communication processes are strictly defined. This is like languages that people need to use to be able to understand each other. Next starting from the Physical layer (bits and bytes) we will move to Data Link layer (Ethernet, MAC addressing and Switching). Next layer will be Network (Routing, IPv4, IPv6, subnetting, network masks, IP addressing, ARP, ICMP). On Transport layer we will discuss in details TCP and UDP protocols and their purpose. On Application layer I will tell you about such important protocols as DHCP and DNS that your computers and mobile phones use very often. Also I will tell you difference between private and public IP addresses and purpose of the NAT.You will also learn how DNS(core of the hierarchical naming structure in the Internet) works and how resolution of each domain name to the IP address happens by involving DNS root nameservers, TLD nameservers and authoritative nameservers.Also it's important to know how routers in the Internet build their routing tables and make routing decisions. That's why I decided to explain you some details about BGP - global routing protocol.In practice sections you will perform multiple practice Networking activities:Install Wireshark and use it for analysis of the networking protocolsAnalyse Ethernet headersUnderstand how DCHP requests and responses help to get IP address assigned to the hostAnalyse structure of the IPv4 headerPractice subnetting Examine ARP cacheExplore IP, DHCP and NAT settings of the Wireless RouterUse nslookup utility to perform DNS and reverse DNS lookups with queries for different types of the DNS records (A, AAAA, TXT, MX)Analyse TCP and UDP headersCheck information about domain names, public IP addresses and ASNs (Autonomous System Numbers)List of the Course Sections and Topics:Introduction to the Computer NetworkingTCP/IP and OSI ModelsBits and BytesEthernetNetwork CharacteristicsSwitches and Data Link LayerRouters and Network LayerIP Addressing and IP PacketsNetworksBinary MathNetwork Masks and SubnettingARP and ICMPTransport Layer - TCP and UDPRoutingNetwork Address TranslationDHCP and DNSDuring this course you will use following Applications to perform different practical activities and analysis of the Protocols and Applications:WiresharkTerminalWeb BrowserWith this course you will get lifetime-long access to almost 200 lectures and tens of practical exercises. After the course you will become a guru of Computer Networking and will be able easily explain what happens when two hosts communicate in the Internet. But most important is that you will UNDERSTAND how Computer Networks work.You will also get 30-days money-back guarantee. No questions asked!Don't wait and join the course now!
