CIT 44000 / 3 Cr.

An introduction to wide area networking (WAN), which is a technology used to extend telecommunications connectivity for information distribution over large geographic regions. Topics include architecture, design, and implementation, as well as the influence of the state and federal regulatory environments.


Course Outcomes (What are these?)

  • Explain the principles of computer networking and WAN concepts (CIT a)
  • Demonstrate an understanding of WAN hardware (CIT a)
  • Configure WAN components (CIT c)
  • Solve technical issues through troubleshooting WAN's (CIT j)
  • Use Cisco routers to configure network devices (CIT i)
  • Demonstrate confidence in working with the evolving technology of computer networking (CIT h)

CIT Student Outcomes (What are these?)

(a) An ability to apply knowledge of computing and mathematics appropriate to the program’s student outcomes and to the discipline.

(c) An ability to design, implement, and evaluate a computer-based system, process, component, or program to meet desired needs.

(h) Recognition of the need for and an ability to engage in continuing professional development.

(i) An ability to use current techniques, skills, and tools necessary for computing practice.

(j) An ability to use and apply current technical concepts and practices in the core information technologies.
