Free Introduction to Networking Book
prostoalex writes "Eugene Blanchard made his Introduction to Data Communications (also known as Introduction to Networking) available for free. The book covers a broad variety of topics such as RS-232, Ethernet, RF, TCP/IP and many other topics in its 63 chapters. This is a valuable reference and read for those just starting to understand networking and data communications as well as seasoned professionals in the field."
That has nothing at all to do with the subject matter the book is about. The basic concepts that these intro to data comm. textbooks cover have not changed since the 60's.
I wish this had been availlable 4 years ago while I was still in University, it would have saved me $70.
