else?
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

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.

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)

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

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

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
