Information Security by Josh Riverside
The latest technological advances have made the world a global village and allow communication at the speed of thought. Using the Internet, vital personal, official, or financial data can be shared or transferred across the globe within seconds. This has not only changed the very social,... The aim is not data transmission, but secure data transmission. ... This means that training employees for handling data transmission should be a continuous process. ... The hackers are not lagging behind, and they too have devised all possible ways conceivable to breach the security involved with the...

Data Fiber Optics – Light Speed Transmission by Mikael Rieck
Why settle for slow speed, high electricity costs and a technology invented a hundreds years ago if you can have the latest in data transmission at less the cost and many times the speed? With the use of glass or plastic threads to transmit data the fiber optics is an upcoming technology. ... This is mainly due to the data transmission speed and the fact that it doesn’t require electrical impulses to move the data. ... A transmitter is an electronic device that sends an electromagnetic signal with the aid of an antenna, essentially taking information and converting it to a signal for...

What Are HDMI And DVI Cables by Jimmy Mehta
HDMI or High definition multimedia interface was developed in the middle of 2003 is a new developed interface for full digital transmission of digital audio and video data from the personal computer to the monitor. And is available as version 1.3 since June, 2006 HDMI Cables was introduced... There are several types of DVI : DVI-I (integrated, that means it can transfer analogue and digital data) DVI-D (digital, only digital data transfer) DVI-A (analogue, only analogue data transfer) The quality of the video output is dependent of the quality of all components of the system...

Back To The Basics: Communication Devices by Deb Jensen
Since today's communication technology can be confusing for many people, Genesis Global, Inc. wants to go back to the basics and take a brief look at the various types of communication channels available. This article addresses eight basic factors which affect data transmission: "transmission... Parallel Transmission Serial: Bits of data travel through channels sequentially—one bit of data follows the next (as in the case of twisted-pair telephone lines). ... That is, a "start" bit represents the beginning of a character, and a "stop" bit represents its end." Synchronous: (timed...

Virtual Private Network and Network Connections by Aaron Adams
Network In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks. Local Area Network (LAN) A local area network (LAN) is a group of computers and associated devices that... Network Backbone A backbone is a larger transmission line that carries data gathered from smaller lines that interconnect with it. ... Nodes In a network, a node is a connection point, either a redistribution point or an end point for data transmissions.

High Speed Downlink Packet Access by Riktesh Srivastava
The Technology As we saw, the 3.5 G standard used in HSDPA is an improvement upon the 3G protocol used in W-CDMA technology. With HADPA, the data transfer rate improves over W-CDMA by a factor of at least five. Theoretically speaking, it is possible to reach data transmission speeds of 8-10... In other words, the data received at the base station is ‘processed’ to manage any corruption the data may have gone through at the time of the original transmission. ... Here, the retransmissions have different codes of the data against the codes of the original transmission.

BlueTooth Technology by Jith Crs
Bluetooth is the name given to a new technology standard using short-range radio links, intended to replace the cable(s) connecting portable and fixed electronic devices. The standard defines a uniform structure for a wide range of devices to communicate with each other. ... It provides two different kind of physical links with their corresponding baseband packets, Synchronous Connection-Oriented and Asynchronous Connectionless which can be transmitted in a multiplexing manner on the same RF link.Asynchronous Connectionless (ACL) packets are used for the transmission of data only while...

The Truth: Netzero 3G by Jacob Bodnar
We've all seen the ads on TV for Netzero 3G. You know the ones, "speeds so fast you sworn it was broadband" Well if your using it, you may not think it really is. We're going to break down the truth behind, Netzero 3G. Netzero explains the idea of their service perfectly. ... "NetZero HiSpeed 3G is not a broadband service and actual data transmission rates are not faster than standard dial-up Internet service" What this means is that the speed that data is sent into your home is no faster than regular dial-up.

HDMI Extender: Solution to HDMI Transmission over Long Cables by Jeff Su
Background: The main advantages of HDMI, high definition multimedia interface, over standard analog video transmission is that it is 100 % digital from source to display. However, transmitting HDMI over long distances is not so easy. In this article we will describe some of the issues... Basic HDMI transmission characteristics: HDMI is based on TMDS, transmission minimized differential signaling, developed by Silicon Image. ... In order to support non-compressed HD video quality, HDMI needs to support data rates up to ~1.65 Gbps for each of 3 transmission pairs.

What You Need To Know About Cables by Elizabeth Morgan
Cables are electric conductors covered with insulating material. They are used to connect different components of a system such as connecting a DVD player with a TV. Cables are being used in almost every area of human activity. Cables of different make and uses are now available in the market. ... Data transmission is now faster than it used to be and this speed has helped with the growth of the information technology and telecommunications industry. ... Internet service providers and telecom companies have also laid thousands of miles of high-density data transmission cables.
