چرا فناوری اطلاعات ؟

- قدرت نفود - سرعت تغییر وتکامل - کاهش قیمت ها - نیاز به زیرساخت - قدرت نفود - سرعت تغییر وتکامل - کاهش قیمت ها - نیاز به زیرساخت

Why IT ? Why Now? 1973: 1 million instructions/sec Computers are faster 1973: 1 million instructions/sec 2007: 8 billion instructions/sec Have more main memory 1973: 0.125 megabytes 2007: 8.0 gigabytes Cost less 1973: $4,000,000 2007: $1,000 Speed*size*cost improvement factor: 100 billion

Why IT ? Why Now? Have more disk storage Higher communication speeds IMPROVEMENT: 12000 x Have more disk storage 1973: 10 MB 2007: 250,000 MB (soon 1 terabyte = 1000GB) Higher communication speeds 1973 Modem 300 bits/sec 2007 Modem: 56,000 bits/sec DSL (high end) 7,000,000 bits/sec Optical 10,000,000,000,000 bits/sec 1973-2007 IMPROVEMENT: 30 BILLION x

It's a hard disk drive back in 1956. with 5 MB of storage. In September 1956 IBM launched the 305 RAMAC, the first 'SUPER' computer with a hard disk drive (HDD).  The HDD weighed over a ton and stored a 'whopping' 5 MB of data

INTERNET WORLD USERS BY LANGUAGE

A World of Contrasts Knowledge Divide or Digital Divide Access to knowledge and Information Prosperity Globalization Inclusion Knowledge Divide or Digital Divide Limited access to knowledge and information Poverty Marginalization Exclusion The role of WSIS cannot be overstated in placing the issues of access to knowledge and its role in responding to development challenges, as well as the digital divide, centre-stage on the international agenda. The Summit in Geneva and Tunis provided an important platform for promoting UNESCO’s concept of knowledge societies. Presently, UNESCO’s focus is on making its concept of knowledge societies operational and it concentrates on implementing many of the recommendations of the Geneva Action Plan and Tunis Agenda. UNESCO’s actions include up-stream policy initiatives including the preparation of studies, recommendations, guidelines, implementation of grass roots projects and training initiatives, provision of information management tools as well as knowledge management and monitoring services.
