The Consumer Electronic (CE) market is in a revolutionary phase now. Because of the changing needs of consumers, organizations are forced to come up with new set of products in a very short span of time with more features and less price. Broadly the CE devices are used for Communication (Mobile phones), Storing personal information (PDA) and for Entertainment (Digital cameras, music players). At one end CE devices are marching towards ‘Convergence’ phenomenon, where the above said three elements are integrated into a single device (Say iPAQ) and on another end devices are marching towards ‘Divergence’ phenomenon, where each CE device is produced with a unique purpose in mind. For example latest Sony T5 cameras are having very high resolutions (5 Mega pixels) which are aimed at pro-sumers or photo-enthusiasts. This Convergence and Divergence (C & D) has created huge variety of devices which is making the consumer confused. Irrespective of the type providing connectivity to the Personal Computer (PC) or Internet has become the necessary requirement for all these devices. After working in the consumer connectivity domain for about five years now I am able to see the ‘Universal Serial Bus’ (USB) is emerging as a technology which is addressing the need for connectivity and truly living up to its name ‘Universal’. The reminder of this write-up will compare USB with other technologies and talk about some of the limitations of USB as well. |

The Embedded Systems domain is poised for a huge growth as more and more embedded devices are flocking into the market. These Embedded devices range from small consumer electronic devices (like mobile phones) to enterprise devices (like telecom switches). Even though the size of these devices varies, the programming fundamentals remain almost the same. In this article we will discuss about building blocks of embedded systems from a programmer’s perspective. |

In our previous month's article on scripting, we discussed the importance of regular expressions. But the question is, can the regular expressions alone make the scripting powerful? The answer is No. Then how can we make our scripts really powerful? It is indeed the core set of commands, along with simple and easy file operations, that imparts the functionality to scripting and makes it powerful. |
