Document Summary

Lossy (once parts of image are discarded can"t get it back) compression - omits some pixel colours. Offers 2^24 = 16,777,216 (16 million diff colours) Dithering can make the illusion of additional extra colours. Lose 15% if you don"t submit on owl, save email confirmation. Mc4 ta consulting next week, schedule on owl. Network: a group of interconnected computers (could be connected with wires, wirelessly, satellite) Let"s look at some ways to configure a network and think about the pros and cons of each configuration and cons of each configuration. Internet: a global system of interconnected computer networks that use the standardized internet protocol suits (tcp/ip) to serve billions of users worldwide. The worldwide web (www) is software runs that on the internet. There are various protocols (standard procedures) to govern how data is transmitted online so that they are universal. The ideas behind this protocol were funded by the advanced research.
