Understanding the Basics of Data Communications
Understanding the Basics of Data Communications course provides students
with the basic knowledge students need to become conversant with modern data
networks. Students will receive the historical perspective necessary to
understand how and why the technology evolved to its current widespread
deployment and use, and get the background they need if they are entering the
technology field with little or no technical background. Like any technology, it
has its own language base; so as an introductory course it leads into more
complex subjects. One might say this is Data Networking 101. We are faced with
rapidly changing technologies, and professionals have to come up to speed
quickly. To take an advanced course without understanding the fundamentals
creates frustration and loss of productivity; therefore, this is a good course
to start with.
