The seminal work is TCP/IP Illustrated Volume 2 (Gary Wright and W.
Richard Stevens, Addison-Wesley). Whilst dated it will give you an
overview of how all the parts in the BSD networking stack fit together.
It really needs to be updated, however enough things are in flux
right now that summarising all the changes would be difficult until say
after FreeBSD 8.0 dust is settled.
For computer architecture, probably best to learn PC architecture
these days -- x86 is here to stay, kids, and Netbooks are something of a
reactionary response triggered by the One-Laptop-Per-Child (OLPC)
project. In my day, I learned 68000 assembly and C on the Amiga.
Hans-Peter Messmer's "The Indispensable PC Hardware Book" is a huge
book which cost me about 50 GBP new when I first bought it -- I was
working in a reasonably well paid job at the time, but it can be found
second hand no doubt around the world.
Cover to cover it will tell you what you need to know about how the
PC architecture fits together, but if you need more detail e.g. on stuff
like FreeBSD network drivers, again, it's best to refer back to the
source code itself.
Hope this helps.
cheers
