Course Descriptions & Student Learning Outcomes

CENT 140 - Computer Networking I

  • Prerequisite: CENT 132

This course introduces the OSI and TCP/IP models, industry standards, commonly used network topologies, IPv4 and IPv6 addressing, basic network copper cabling, routing and switching concepts, VLANs, distance vector and link state routing protocols, ACLs, DHCP, NAT, and the configuration and use of routers and switches in the network. This course helps to prepare the student for the Cisco Certified Entry Networking Technician (CCENT) exam.

2 hrs. lect.; 6 hrs. lab. per week

Student Learning Outcomes

Upon successful completion of CENT 140, the student will be able to:

  • Describe the basic requirements for a reliable network.
  • Describe the purpose, functions, characteristics, network devices, and protocols associated with each layer of the OSI and TCP/IP reference models and explain how the TCP/IP and OSI models are used to facilitate standardization in the communication process.
  • Describe the characteristics and identify industry standards for copper cabling, fiber-optic cabling, and wireless network media and construct copper network cables.
  • Identify and describe the purpose and characteristics of Ethernet framing, MAC addresses, and ARP.
  • Describe the characteristics, purpose, and use of IPv4 addresses and subnet masks; public and private addresses; and unicast, multicast, and broadcast addresses.
  • Describe the representation, characteristics, purpose, and use of IPv6 addresses and network prefixes and IPv6 global unicast, link-local, and multicast addresses.
  • Design and implement fixed and variable length IPv4 addressing schemes including:
    • Determining the subnet mask to support a specified number of hosts to be assigned to each subnet and
    • Determining the subnet addresses and range of host addresses for each subnet for the final addressing scheme.
  • Describe commonly used Application Layer protocols that provide IP addressing and network services.
  • Use the output of ping, tracert, ipconfig, and show commands to establish network baselines and perform troubleshooting within a network.
  • Explain how frames are forwarded in a switched network and how packets are forwarded in a routed network.
  • Describe the purpose and use of dynamic routing protocols, static and default routes, and manually configured summary routes to interconnect devices in different networks.
  • Describe and identify commonly used distance vector routing protocols, such as RIP and RIPng, and link-state routing protocols, such as OSPFv2 and OSPFv3.
  • Explain how ACLs are used to filter traffic for IPv4 and IPv6.
  • Describe the characteristics, benefits, drawbacks, and operation of DHCP and NAT in IPv4 and IPv6 networks.
  • Configure routers and switches for IPv4 and IPv6, including basic configuration, ethernet and serial interfaces, VLANs, inter-VLAN routing, static and default routes, summary routes, RIP and OSPF routing protocols, access control lists, DHCP, and NAT.
  • Identify basic security threats and vulnerabilities and describe device hardening and mitigation techniques and security best practices.
