Curso de Redes TCP/IP - Protocolo de Redes de Computadores

40 horas
Visão Geral

TCP / IP é o grupo mundialmente aceito de protocolos no núcleo da Internet e intranets organizacionais.

Uma sólida compreensão de cada um destes protocolos e como eles funcionam vai lhe dar a capacidade de implantar a rede mais eficaz para a sua organização.

Neste curso, você vai ganhar o conhecimento e as habilidades necessárias para instalar, configurar, um apoio essencial e solucionar problemas de rede TCP / IP-based.

Objetivo
  • Os elementos essenciais do conjunto de protocolos TCP / IP
  • Instalar e configurar o TCP / IP em uma rede de sala de aula ao vivo
  • As funções dos vários dispositivos de uma rede TCP / IP
  • Endereçamento IP e sub-redes, incluindo comprimento variável de sub-rede de mascaramento (VLSM)
  • Sub-rede de uma rede IP e implementar os endereços resultantes
  • Detalhes da ARP, IP, ICMP, TCP e UDP – suas funções e relações
  • Automatizar a atribuição de endereços e resolução de nomes usando DHCP e DDNS
  • roteamento IP e os protocolos que o suportam, como RIP e OSPF
  • Como aplicações como FTP, HTTP, Telnet, e outros trabalham em uma rede TCP / IP
  • Funções do IPv6 e seus protocolos
  • Funções e capacidades de multicasting, Voz sobre IP, e e-mail
  • O uso de um analisador de protocolo para isolar e solucionar problemas de rede
  • Solucionar problemas em cada camada de uma rede TCP / IP
