151 As Physical Security Converges With IT Security and Becomes More Network-Based, Can Cisco Compete? Cisco recently introduced new video surveillance IP cameras and monitoring software targeted for small businesses. As corporate security technology and services become increasingly network-delivered and database-driven, the physical security market presents a compelling incremental growth opportunity for Cisco that we believe can exceed the billion dollar annual revenue threshold in the next

has always been a contested idea. Cite one example from the ‘pre-digital’ era, and one from contemporary culture to illustrate your argument. The images of the photographic in the pre-digital era were taken as the proof and evidence of reality. However, today this belief might not hold because of the technology that might aid the editing of the photographic to assume content and the background preferred by the user. At the pre-digital era, no such techniques were available and the possibility of an

Electrical (EEE) / Instrumentation (EI or AE&I) Engineering or Sciences 1INTRODUCTION Are you tired of slow modem connections? Cellonics Incorporated has developed new technology that may end this and other communications problems forever. The new modulation and demodulation technology is called Cellonics. In general, this technology will allow for modem speeds that are 1,000 times faster than our present modems. The development is based on the way biological cells communicate with each other and nonlinear

CLASSIFICATION OF COMPUTERS By the type of data they manipulate · Digital computers. A computer that stores data in terms of digits (0's and 1's) and proceeds in discrete steps from one state to the next. The states of a digital computer typically involve binary digits which may take the form of the presence or absence of magnetic markers in a storage medium, on-off switches or relays. In digital computers, even letters, words and whole texts are represented digitally. They have the ability to

Information technology (IT) is the application of computers to store, retrieve, transmit and manipulate data,[1] often in the context of a business or other enterprise.[2] IT is considered a subset of information and communications technology (ICT). In 2012, Zuppo proposed an ICT hierarchy where each hierarchy level "contain some degree of commonality in that they are related to technologies that facilitate the transfer of information and various types of electronically mediated communications."

channels. The exceptional growth in number of TV channels combined with the inherent limitations of the analog cable TV systems has posed several challenges to the cable TV sector,mainly due to capacity constraints and non-addressable nature of the network.With time and evolution of technology, new addressable digital TV platforms like DTH,IPTV etc. are now available.The evolution of technology has also paved the way for bringing about digitization with addressability in the cable TV sector
