Study Notes

Network Communication Concepts

  • CO 2: Apply network hardware components to establish network communication.
  • Week 4-5 ULOs: Troubleshoot simple network problems using TCP/IP commands and create LAN cables (straight-through and crossover).

Metalanguage

  • TCP/IP: Transmission Control Protocol/Internet Protocol; a standard protocol for digital computers to communicate over long distances.

  • Protects the system from malicious software and enables network reconfiguration.

TCP/IP Commands

  • System commands for network analysis and troubleshooting.
  • IPConfig: Displays network adapter configuration (includes important information like IP address).
  • Ping: Tests connectivity to hosts (checks if a host exists on the network and returns data about response time).
  • arp: Displays the MAC address-to-IP address mapping.
  • Netstat: Displays network connections (numerical form).
  • Tracert: Shows the path to a destination on a network (measured in hops).
  • Nslookup: Finds the IP address or domain name of a given host.

Example of TCP/IP Commands

  • ipconfig /all: Displays complete network configuration.
  • /renew: Renews IPv4/IPv6 address.
  • /release: Releases/deletes IPv4/IPv6 address.
  • /flushdns: Purges the DNS resolver cache.
  • /displaydns: Displays DNS resolver cache contents.

Quiz/Lab Activity Scenarios

  • Scenario 1: Troubleshooting file sharing between laptops (check file and printer sharing settings).
  • Scenario 2: Checking internet connection issues (perform troubleshooting using TCP/IP commands).
  • Scenario 3: Checking network connectivity (use TCP/IP commands).
  • Scenario 4: Avoiding risks to the computer system from virus-containing downloaded files (avoid accessing malicious websites).
  • Scenario 5: Checking response time and hops when accessing a website (use TCP/IP commands).
