1. IT 101 – Helpful IT Concepts Presented ByRichard Genzer, CEOGenzer Enterprises March, 2013

2. Are You Ready? Select Top Technology Trends for 2013* • Internet of Things • Cyber security • Big data • Cloud computing • Next gen mobile Other sources: • Agile dev • TV integration • Social, social, social • Device integration (e.g. glass, monitor) Can you leverage, cost, approximate, follow or align without understanding? * IEEE 13 Top Trends for 2013

3. What do they mean… to you? • Internet of Things • Connecting “ordinary things” to the net like your car, house or refridgerator • Cyber security • Keeping you and companies safe from interlopers • Big data • Mining the mountains of data to discover useful information • Cloud computing • Leverage centralized computing capacity and build an elastic infrastructure • Next gen mobile • More capablities, better screens, improved connectivity • Agile dev • New ways (iterative / collaborative) to develop products / services • TV integration • One of the “internet of things” from above • Social, social, social • Everyone seems to think we want to be social but do so online? • Device integration (e.g. glass, monitor) • New classes of devices that can be accessed (e.g. heart monitor)

4. What do YOU want to talk about? I am prepared to talk about the following: • Networking • Internet pipes and technologies • Browser technologies • Encryption • Cloud computing • Development What else?

5. Networking • Every device is uniquely addressed • Data is sent in packets, streaming a challenge • Networks require traffic police (routers) • Networks are dangerious (firewall) • Servers and users are connected • Ports allow traffic to be segregated • Increased traffic means bigger pipes

6. Domain Names • People don’t do numbers… need names • Top level domains (.com, .org, .edu, .xxx) • Works from right to left • About 150MM w/ 100MM .com (www.dailychanges.com) • Find (www.godaddy.com), Register, Setup, Maintain • DNS system • Globally replicated database • TTL

8. Encryption • Keep data safe from prying eyes • Keys unlock the information • Inverse keys… key to encode and a different key to decode • Public / private key • Challenge / response, two-factor • Using the same key (symmetric) is dangerous and cumbersome.

9. Cloud Computing • On demand • Scalable • Ubiquitous • Virtualized • Model: pay as you go (no CAPEX) • Uses • Storage: supporting applications (e.g. evernote) • Storage: supporting private apps (e.g. sharepoint) • Virtual computing: support dynamic hosting (e.g. ecommerce)

10. The Browser • Top Browsers • Chrome, IE, Firefox, Safari • Mobile versions of them all • Started as static, now program environment • html5test.com, rogerdubuis.com, bjork.com • Differences • Language support: HTML, CSS, JavaScript, Flash • Layouts change

11. Development Soup • Agile • Programming languages vs programming environments • WordPress, Joomla, • LAMP • .NET vs anything else (ruby, python, PHP) • Open vs. closed environments • MySQL (open) vs stuff from Microsoft or Oracle • Ecommerce platforms • 3-tiered, middleware, multitiered • Model View Controller (MVC)… .NET, Cake, Django • Usage scenarios / stories

12. Databases • Table: each with one or more columns • Columns: (fields) each with a type • Keys: locate/refer row quickly • Normalization: so data is not repeated • Lesson: keep data clean so database is fast, efficient • duplicate data, “messy” information

13. Other Fun Things to Talk About • Google Docs • Mobile Computing & Tablets • IT and Developing Countries • Online Video & Education • Viruses, Trojan, Key Logger, Assorted Malware • VOIP • Web Monitoring
