第二章TCP/IP—iOS网络七层模型

分层：七层模型：应用层，表示层，会话层，传输层，网络层，数据链路层，物理层简介：七层模型，亦称OSI(Open System Interconnection)参考模型，是参考模型是国际标准化组织(ISO)制定的一个用于计算机或通信系统间互联的标...

网络七层模型和tcp工作原理

一、OSI七层模型与TCP/IP五层模型（1）OSI七层模型：OSI七层模型是由ISO国际标准化组织提出的，主要是为了统一世界各计算机厂商使用不同的私有模型而导致互相无法正常通信的问题，每一层都有每一层的功能应用层主要就是为用户服务的，提供了大量人们所普遍需要的协议，httpd、dns等表示层完成特...

【计算机网络】网络通信基础(IP地址，端口号，五元组，OSI七层模型，TCP/IP五层模型，封装和分用)

初识网络网络互连随着时代发展，需要计算机之间相互通信，共享软件和数据，即多台计算机相互协同工作来完成某个业务，就有了网络互联网络互联：将多台计算机连接在一起，完成数据共享数据共享的本质是网络数据传输，也称网络通信，即计算机之间通过网络来传输数据根据网络互联的规模不同，可...

Internet协议栈 TCP/IP模型、以太网封装以及解封装过程、物理层、链路层、网络层、传输层、应用层的作用 OSI七层模型

TCP/IP参考模型以太网数据封装以及解封装过程：数据封装应用层：数据单元传输层：数据段网络层：数据包网络接口层：数据帧（osi第二数据链路层）各层次的传输数据单元物理层：发送端：将上层交过来的帧，将帧当中的bit或一些bit把他变成物理信号、电磁波的信号，让这些...

第二章 TCP/IP-IOS七层模型

一.IOS七层参考模型国际标准化组织（International Standard Organization，ISO）1984年颁布了开放系统互连（Open System Interconnection，OSI）参考模型一个开放式体系结构，将网络分为七层。应用层：网络服务与用户的接口表...

OSI 七层模型和TCP/IP模型及对应协议（详解）

OSI 七层模型和TCP/IP模型及对应协议（详解）先看图，有图有真相在OSI七层模型中，处于不同层的中继系统具有不同的名称。一个设备工作在哪一层，关键看它工作时利用哪一层的数据头部信息。网桥工作时，是以MAC头部来决定转发端口的，因此显然它是数据链路层的设备。具体说:物理层...

TCP/IP的七层模型

TCP/IP的七层模型应用层 (Application)：网络服务与最终用户的一个接口。协议有：HTTP FTP TFTP SMTP SNMP DNS TELNET HTTPS POP3 DHCP表示层（Presentation Layer）：数据的表示、安全、压缩。（在五层模型里面已经合并到了应用...

TCP/IP四层模型和OSI七层模型

表1-1是 TCP/IP四层模型和OSI七层模型对应表。我们把OSI七层网络模型和Linux TCP/IP四层概念模型对应，然后将各种网络协议归类。表1-1 TCP/IP四层模型和OSI七层模型对应表 OSI七层网络模型 Linux ...
