This document discusses technology infrastructure and its key drivers. It defines infrastructure as the underlying foundation or base for an organization or system. The five key drivers of technology infrastructure are outlined as: 1) Moore's Law and increasing microprocessing power, 2) the exponential growth of mass digital storage, 3) Metcalfe's Law describing increasing network value, 4) declining communication costs and the growth of the Internet, and 5) the role of standards in ensuring compatibility and communication. Examples are provided for each driver to illustrate the concepts and their technological impacts.
Information Technology Infrastructure
- 2. Presented to…. Sir Umair Aslam Presented By…. Hurriya & Ameera
- 4. MEANING OF INFRASTRUCTURE… • It’s a combination of two words "infra" meaning (below) & "structure“ • An underlying base Or Foundation Especially for an organization or system.
- 5. WHAT IS IT INFRASTRUCTURE…? “Set of physical devices and software required to operate an enterprise”
- 6. The five technology drivers of infrastructure include Moore's Law and Micro processing Power. The Law of Mass Digital Storage. Metcalf's Law and Network Economics. Declining Communication Costs and the Internet. Standards and Network Effects.
- 7. Moore's Law and Micro processing Power.
- 8. Who is Gordon Moore…. Gordon Moore is an American business man, cofounder & chairman of Intel corporation and the author of Moore’s law. Born in Jan 3,1929. (85 years) Gordon Moore is a visionary.
- 9. What is Moore’s law….? “Moore’s law states that the number of transistors on a microchip will increase exponentially typically doubling every two years.” MICROCHIPS: Micro chips are the power houses of electronic industry.
- 10. Variations There are three variations following as: 1) Double Speed: The speeds over a number of years went between 1.3 GHz and 2.8 GHz. 2) Double Performance: Double the number of transistors double the performance.
- 11. CONTINUE…. 3) Half Price: Due to continuously new & improved version of electronics the price rapidly fall within a year or so.
- 12. EXAMPLE…. Intel leads the semi-conductor by delivering. The world 1st 3D tri-gate transistor. Mass produce on the 22nm process in 2011. A new processor generation every two year. A world Wide Filicon Fab.
- 13. Limitations Growth rate may stop between 2017 to 2025 Atomic sized transistors. Intense pressure on technology companies.
- 14. Joke…. There's a joke about personal computers that has been around almost as long as the devices have been on the market……
- 16. Mass Digital Storage…. “ The amount of digital information stored is roughly being doubled every year.”
- 17. Key Points…. The amount of digital information being stored doubles every year. 5 Exabyte of unique information is produced every year. Information growth involve magnetic storage of digital data. Exabyte = a billion gigabyte.
- 18. EXAMPLE NANOTUBES 10,000 times thinner than a human hair. They consist of rolled up sheets of carbon hexagons. Discovered in 1991 Used in making super capacitors. Improves efficiency of electronics.
- 19. Example of PC hard disk capacity...
- 21. Who is Robert Metcalfe….? Robert Melancton "Bob" Metcalfe is an electrical engineer from the United States. He is the co-inventor Ethernet and formulated Metcalfe's Law. Born in April 7,1946.
- 22. Metcalfe’s law…. “In 1970 The Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system.”
- 23. GRAPH
- 24. Limitations…. Difficulty in quantifying the "value" of a network, Metcalfe's law measures only the potential number of contacts. Network saturation & load effects not accounted for Effects of hostile jamming not accounted for. Complex time domain dependencies.
- 25. EXAMPLE Two telephones can make only one connection, five can make 10 connections, and twelve can make 66 connections.
- 27. Declining Communication Cost & The Internet… “Rapid decline in the cost of communication and the exponential growth in the size of internet.”
- 28. Key Points… An estimated 1.8 billion people worldwide have internet access (Internet world stats, 2010.) As communication cost fall to a very small number.
- 29. EXAMPLE Digital Subscriber Line (DSL) and cable modems now deliver a kilobit of communication for a retail price of less than 2 cents.
- 30. Standards … “Specification that establish the compatibility of products and the ability to communicate in a network.”
