What is IT and What Makes Me an Expert?
By Duane Thresher, B.S., M.S., Ph.D., CEO November 8, 2017
Since Information Technology (IT) is really
communication-of-information technology, IT is mostly
computer networking. (Cyber is a prefix meaning IT, so for
example, IT security is also known as cybersecurity.)
"Computer" includes supercomputers, servers, desktops,
laptops, tablets, phones (landlines and cells), TV,
etc. There has been a "convergence" and all of these devices
now communicate — their most important function
— over the same network, the Internet; see
figure. Thus, being an IT expert means being a networking
expert.
Networking, at its first, lowest, physical layer (hardware;
e.g., cables, wireless), is mostly electrical
engineering. At its last, highest, application layer
(software; e.g., web programming), it is mostly computer
science. However, at either end, extensive knowledge of the
other end is necessary. Thus to be a networking expert, you
need an education in both electrical engineering and
computer science from an excellent university.
