Chapter 7: TCP/IP Basics Pg 184 - 198

IP Addresses
- most common IP addresses have a 32-bit value (IPv4)
- 32 binary digits broken into four groups of eight digits
- each 8bit value is converted into a decimal number between 0 and 255

Network IDs
- each computer on a LAN has a very similar IP address
- i.e. only the last number of the IP being unique to each system

Interconnecting
- must have a router to connect to other networks

  1. Check out that last section "Interconnecting", again. "Must have a router to connect to other *networks*", yes, but to connect to "other machines" on the same network segment, no router is needed.
