Expected Duration
90 minutes

In order for devices to be part of a network, each must make use of a cabling medium (if wired), cable connectors and have at least one unique address, most commonly an IP address. This course examines the components and communication mechanisms such as cables, connectors, ports and protocols used to allow computers and networks to communicate with one another and share information. It also deals with the properties and characteristics of TCP/IP, the details of IP addressing including the different types of addresses, how they are assigned and the different classes. It also explains common TCP and UDP ports and protocols. This course prepares the learner for CompTIA A+ exam 220-801.


Cabling and Connectors

  • distinguish between shielded and unshielded twisted-pair cabling
  • describe how fiber cabling works
  • distinguish between RG-6 and RG-59 coaxial cabling
  • use the most appropriate cabling in a given scenario
  • distinguish between how types of connectors are used
  • use the most appropriate cabling in network environments
  • use the most appropriate connectors in network environments

IP Addressing, IP Location, Ports, and Protocols

  • specify the class of an IP address
  • distinguish between IPv4 and IPv6 addressing types
  • identify the default subnet masks for Class A, B, and C networks
  • describe how DHCP assignment works
  • recognize how common ports are used
  • recognize how common protocols are used
  • specify the class of an IP address
  • recognize the functions of common ports and protocols
