课程简介

课程名称:掌握OSI模型的概念 课程概述:在本课程中,您将学习网络通信的基础知识,包括数据在网络上的传输方式,以及逻辑地址在网络通信中的应用。Dhananjay尝试通过OSI模型的七个层次来揭示网络通信的概念。本课程涵盖以下主题: 1. 物理层 - 数据传输基础 - 不同类型的电缆(如铜缆、光纤) - 连接器(如RJ45) - 电压水平和信号传输 - 数据速率和带宽 2. 数据链路层 - MAC地址的介绍 - 以太网及以太网帧 - 错误检测和纠正 - ARP(地址解析协议) - PPP(点对点协议) - 交换和桥接 3. 网络层 - IP地址(IPv4和IPv6) - 路由协议(如RIP、OSPF) - 子网划分和CIDR - ICMP(互联网控制消息协议) - NAT(网络地址转换) - VLAN(虚拟局域网) 4. 传输层 - TCP(传输控制协议) - UDP(用户数据报协议) - 端口号 - 流量控制 - 错误检测和纠正 - 多路复用和解复用 5. 会话层 - 会话的建立、维护和终止 - 检查点和恢复 - 同步 - 会话层协议和API 6. 表示层 - 数据压缩 - 加密 - 数据翻译和格式化 - 字符编码(ASCII、Unicode) 7. 应用层 - HTTP(超文本传输协议) - FTP(文件传输协议) - SMTP(简单邮件传输协议) - DNS(域名系统) - 客户端-服务器架构基础 通过本课程,您将对OSI模型的各层有更深入的理解,为日后的网络通信学习和实践打下坚实的基础。

In this course, you learn about the basics of network communication. All about how the data is transferred on the network and logical addressing to communicate on the network. Dhananjay has tried demystifying the concepts of network communication through the 7 layers of the OSI model.Following topics are covered -Physical LayerUnderstanding the basics of data transmissionDifferent types of cables (e.g., copper, fiber optics)Connectors (e.g., RJ45)Voltage levels and signalingData rates and bandwidthData Link LayerIntroduction to MAC addressesEthernet and Ethernet framesError detection and correctionARP (Address Resolution Protocol)PPP (Point-to-Point Protocol)Switching and bridgingNetwork LayerIP addressing (IPv4 and IPv6)Routing protocols (e.g., RIP, OSPF)Subnetting and CIDRICMP (Internet Control Message Protocol)NAT (Network Address Translation)VLANs (Virtual LANs)Transport LayerTCP (Transmission Control Protocol)UDP (User Datagram Protocol)Port numbersFlow controlError detection and correctionMultiplexing and demultiplexingSession LayerSession establishment, maintenance, and terminationCheckpointing and recoverySynchronizationSession-layer protocols and APIsPresentation LayerData compressionEncryptionData translation and formattingCharacter encoding (ASCII, Unicode)Application LayerHTTP (Hypertext Transfer Protocol)FTP (File Transfer Protocol)SMTP (Simple Mail Transfer Protocol)DNS (Domain Name System)Client-server architecture basics
