Final Project

I made my website so it would be useful for me now, but also helps me build a network for the future. I can make work for free now, hopefully for people that will refer my graphics to future clients. I will continue to build my portfolio and learn how to be more professional. Right now I can help others so they possibly help me.

Chapter 6: Continued

Every node in every network has its own address to make sure the data reaches its right destination. A standard IP address consists of four groups of numbers that range from 0 to 255, each group being separated by a period. Every 8-bit number in your IP address is called an octet. The combination for each of these quartets is 256. Once you combine all four of these octets you have 4,294,967,296 different values. There is a classful routing system that is used to assign specific IP addresses by classifying them in networks as Class E to Class A in order to maximize the number of IP addresses on each network. Class A and B are usually for big business, governmental, and education networks. Class C is used for smaller networks. Domain name systems (DNS) are a hierarchy of different servers to resolve domain names by translating those names into IP addresses.
