2 Agenda Modelo de Multicamadas Camada de Aplicação
Camada de Transporte , Visão Geral Camada de Rede, Visão Geral Camada de Enlace Camada Física For the best student learning experience, we recommend a typical lab size of 12 to 15 students and a ratio of one Lab PC per student. A ratio of one Lab PC per two students is the minimum acceptable for the hands-on lab activities. Some of the lab activities require the student Lab PCs to be connected to a local network. Additionally, the computer lab should include two instructor workstations. One instructor workstation should be connected to the Internet in order to search for and download files. The other instructor workstation can be used for hands-on lab demonstrations. The student Lab PCs will be in various states of assembly and repair and are therefore not suitable for reading the curriculum.

4 Modelo Multicamadas Benefícios do Modelo de Camadas
Auxilia na elaboração do protocolo, porque os protocolos que operam em uma camada específica possuem informações definidas de que atuam sob uma interface definida às camadas superior e inferior. Estimula a competição porque os produtos de diferentes fornecedores podem trabalhar em conjunto. Impede alterações de tecnologia ou capacidades em uma camada de afetar outras camadas. Fornece um idioma comum para descrever funções e capacidades de rede.
