If you are using A) MS Windows and B) a small local network and if you C) share resources (which is a common situation) then when you D) connect to the internet, these resources are made available to the internet BY DEFAULT! Since many people (most people) don't know this, it is a common opening for hackers.
Windows 95 and 98 automatically bind the local network device sharing services to the internet connection. It is then possible to send a request for a list of available (shared) devices from anywhere on the internet and your machine will respond with all the devices you share on your local network (hard drive, printers, etc...) and with your user name and local network name! Now the hacker only needs to guess the password (and many people just leave the password blank) to have access to whatever you have shared and maybe to the rest of the network.
"In the beginning ARPA created the ARPANET.
And the ARPANET was without form and void.
And darkness was upon the deep.
And the spirit of ARPA moved upon the face of the network and ARPA said,
"Let there be a protocol," and thre was a protocol.
And ARPA saw that it was good. And ARPA said, "Let there be more
protocols," and it was so. And ARPA saw that is was good.
And ARPA said, "Let there be more networks," and it was so."

Another very good resource for understanding TCP/IP at the byte level is to read some of the Linux network drivers and other source. A large amount of the code is commented and easy to understand even if you are not a seasoned programmer.+
