The Future of Print Media After the proud reign of almost 560 years‚ print media is now facing its greatest challenge against modern technology for survival. Electronic media has lived for almost 50 years and now it seems confident enough to take over. But surely it has still a long way to go before it surpasses its predecessor. By print media we mostly understand newspapers‚ magazines‚ hard copies of books and written or printed documents. On the other hand electronic media provides information

Qn: Is there still a place for print media today? Intro paragraph: Print media has been becoming more and more obsolete nowadays‚ with the rise of digital media where information and news is conveyed almost immediately. There is a rapid rise in the various types of media and print media like newspapers and magazines are becoming less and less utilized. However‚ the print media still occupies a significant place in the world in modern time‚ where it may be seemed as an alternate form of media to

hertz; the digital bandwidth‚ in bits per second. Figure1.2 Bandwidth Signals: Analog or digital Signals can be analog or digital. Analog signals can have an infinite number of values in a range; digital signals can have only a limited number of values. Analog signal has infinitely many levels of intensity (infinitely many values‚ continuous values) over a period of time. Digital signal has only a limited number of defined values (discrete values) say‚ 0‚1. Figure 1.3 Analog and Digital Signal

ADC0803‚ ADC0804 ® Data Sheet August 2002 8-Bit‚ Microprocessor-Compatible‚ A/D Converters FN3094.4 Features The ADC080X family are CMOS 8-Bit‚ successiveapproximation A/D converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs. These converters appear to the processor as memory locations or I/O ports‚ and hence no interfacing logic is required. The differential analog voltage input has good commonmode-rejection

Repeater: operates at physical layers of osi model. Digital signals or analog signals that carry digital data can only be transmitted over a limited distance. After a certain distance attenuation or noise endangers the integrity of that data. Repeaters reproduce and transmit the received digital data. This new signal is the exact duplicate of the original signals. Repeaters offer simple means to extend a network‚ increased traffic on the network is introduced. This increased network congestion may

used in a corporate environment? I like to think of a CSU/DSU(Channel service and Data service unit) as something similar to a modem. In general Dial-up or DSL service a modem is required to convert digital signals to analog and vice versa. A CSU/DSU acts in the same way. The CSU/DSU converts the digital data frames that local area networks (LAN) uses into a frame a wide-area network (WAN) uses and just like the modem it will change the frames back to go the other direction across the network. Within

Before I say anything‚ I’d like to do a little survey. How many of you have an ipad or an e-reader? Do you prefer reading on the ipad or reading a paper book? A couple of weeks ago I read an article on the New York Times website‚ it is called “Long Live Paper” written by Justin B. Hollander. The argumentation of the author was aroused by the US Education Secretary Arne Duncan’s declaration of "Over the next few years‚ textbooks should be obsolete." but According to the author; good old paper
