Wireless technology that is used in small computing devices and mobile communications devices is the same radio technology. Radio technology is based on the wave phenomenon. A wave is a characteristic of vibrating molecules, which you move a knife up and down in the still water of the dishpan. Many small computing devices and mobile communication devices use radio waves and light waves to transmit and receive information. Radio waves are used by cellular technology, PDA (Personal digital assistant), wireless modems for communication.

Infrared light waves are used by PDAs to exchange information between PDAs and Laptop/desktop computers and among other PDAs.

The infrastructure of the cellular telephone technology is the backbone of the wireless small computing mobile communications and enables these devices to connect to traditional communication systems.

Cellular telephone network comprises mobile transceivers called cellular telephone abd a network of fixed transceivers called base stations that are strategically positioned along the terrain. Base stations are used to connect cellular telephone to the ground-based telephone system.

Smart Card: A smart card is a mobile small computing device that is used to store secured information. Smart cards are replacing magnetic strip cards such as credit card. It has an 8-bit CPU and 64 KB of EEPROM along with a modest amount of memory.

Akros takes you to the next level of web application development with the concept of Rich Internet Applications (RIAs). You may have seen applications developed natively in Flash itself and realized that it offers a much more robust experience for the user where productivity is bolstered by ease of use, streamlined workflow, and real time interactivity that is impossible to accomplish in HTML itself. However developing rich applications in Flash for those who are core developers is daunting and unintuitive. The Flash development tool is geared for designers, and developing on a timeline is a strange concept. Flex removes that barrier to entry by providing a programmatic way for developing these RIAs.

What is an RIA anyways? Well HTML applications are state-less. Application servers maintain state by using cookies and session variables to keep track of users, but all the logic is on the server. So while a user is looking at a page in their browser, the application is unable to do anything until the user commits an action that sends data from the page back to the server for processing. The code processes the data, and generates resulting HTML that the browser loads back in.
