Examination Council (ITPEC for short) is the
organization for promoting the standard of IT
professionals throughout the Asian countries.
It was formed on
November 11, 2005 to co-ordinate the efforts
of member countries in the implementation of
the IT Professionals Examination in Asia.
The council is currently comprised of
members from 7 countries the Philippines,
Thailand, Vietnam, Myanmar, Malaysia,

Today’s Presentation
1. The Network Economy
2. Technology Matters
20
2. Technology Matters
3. Open Source Software
The New Economy
• A controversial issue
• The importance of knowledge
• High tech often replaces human communication
and brainpower
• Electronic transactions
21
The Network Economy
• The advent was foreseen in 1969 by Peter DruckerDrucker• Teacher, writer, consultant, thinker, and lecturer
on the contemporary organization
• Wall Street Journal editor and frequent HBR contributor
22
The Network Economy
1. Connected World
• Increasing Web traffic
• Novice users acquire computes
• New web participants• Web bots, intelligent agents, mobile objects, etc.• Web bots, intelligent agents, mobile objects, etc.
• Moore’s Law
• Gilder’s Law
• Metcalfe's Law23
The Network Economy• The observation made in 1965 by Gordon
Moore , co-founder of Intel.
• The number of transistors per square inch on • The number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented.
• Moore predicted that this trend would continue for the foreseeable future.
• Currently, it is 18 - 24 months.• Currently, it is 18 - 24 months.
• Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades.
24
The Network Economy
Gilder’s Law• The bandwidth of both wired and wireless • The bandwidth of both wired and wireless
networks has been continuously increasing• Follows the Gilder’s Law• Bandwidth grows three times as fast as the
CPU speed• This trend facilitates the development of
various innovative technologies, including wireless Internet access and mobile portals
25
The Network Economy
2. Exponential Value
• As the number of nodes increases linearly, the • As the number of nodes increases linearly, the
value of the network grows exponentially
• The network’s value is derived from plentitude
• E.g., as volume of online transactions increases, • E.g., as volume of online transactions increases,
the cost of every transaction diminishes
26
The Network Economy2. Exponential Value
• Metcalfe's Law
• Robert Metcalfe founded 3Com Corporation and
designed the Ethernet protocol for computer
networks
• Metcalfe's Law states that the usefulness, or • Metcalfe's Law states that the usefulness, or
utility, of a network equals the square of the
number of users
27
Utility
Metcalf’s Law
Utility = Users2
Users28
METCALFE’S LAW
The value of a network is proportional to the square of the number of nodes on the network.
Metcalfe’s law relates to the power of an interconnected network to enable collaboration and extend the reach of an organisation. We often forget that Internet is short for ‘Interconnected network’
The web followed what is known as Metcalfe’s law first stated by Bob Metcalfe, who was co-founder and former chief executive of networking company 3Com. He was reputed to have said in presentations made for the company:
‘The power of the network increases exponentially by the number of computers connected to it. connected to it. Therefore, every computer added to the network both uses it as a resource while adding resources in a spiral of increasing value and choice.’(Dave Chaffey, April 2005 ).
Dr. Michael D. Featherstone 29
V α N²
V= Value of the network
N=Number of nodes in the network
What is the ‘Value’ of this network?
N=Number of nodes in the network
Metcalfe’s Law relates the value of a digital network to the number of connections (or users or members) it has.

The Network Economy
3. Lifespan of Innovation
• Ideas spread really fast
• Hard to achieve a sustainable competitive
advantage
• Continuous innovation
32
The Network Economy
4. Increasing Returns
• After the dot-com crash, some individuals have • After the dot-com crash, some individuals have
become ‘dot-com averse’
• Under investing vs. over investing
• E.g., continuous investing in a market leader will
make it stronger and weaken the competitors
33
The Network Economy
5. Decreasing Prices
• Consumers may count on superior quality for • Consumers may count on superior quality for
less price over time
• Scientists find ways to get more out of less
materialmaterial
• Computers, cars, electronic devices, computer
memory, etc.
34
The Network Economy
6. Information is the king!• The value of accurate and timely information
increasesincreases
• If you have perfect information, the best deal is guaranteed
• Technology may empower the user
35
The Network Economy6. Information is the king!
• Shopping bots – price comparison engines
• Perfect information
• Try to search for one of course textbooks
• E-vendors tend to commoditize offerings
• Name, delivery options, shipping time• Name, delivery options, shipping time
• Single free competition market with zero long-term
profit – Price wars
• E-vendor bots36
The Network Economy
7. People expect free
• Freeware or at least trial versions of software • Freeware or at least trial versions of software
programs are taken for granted
• Get a product for free and pay for service or
supportsupport
• E.g., Java language, Open Source Software,
OpenOffice.org, LibreOffice, Joomla, Wordpress
37
The Network Economy
8. High Dependency
• In a linked economy, the fate of an organization • In a linked economy, the fate of an organization
depends on other companies in the supply value
chain, their competitors, and the external
environment
• Organizations have to become highly adaptive
38
The Network Economy
9. High Rate of Displacement
• The agricultural era – industrial era
• People have to change professions
• Companies have to change product lines and
restructure

Technology Matters!
Technological evolution, choice, transfer, and adaptationtransfer, and adaptation

Two intertwined technological forces
The Moore’s law –the acceleration of computing power doubles about every 18 months power doubles about every 18 months One of Intel’s cofoundersthe faster, smaller, and cheaper digital devices
The Metcalfe’s law —the extending connectivity squares the network utility The inventor of Ethernet and the 3Com’s founderv=n², v=utility, n=the number of connected nodesv=n², v=utility, n=the number of connected nodes
Reach and Richness contributed by wireless and broadband
42
Hardware innovation• Processor & Storage: exponential
growth• The speed & value attributed by the • The speed & value attributed by the
Moore’s law bypassed the constraints of Rock’s law
• Handheld & wearable IT devices• Miniaturization & pervasiveness —• Miniaturization & pervasiveness —
ubiquitous connectedness of embedded systems between and within home, office, and any entities.
43
Software creativity• From proprietary to Portability &
Interoperability• The platform/structural organizer of value network • The platform/structural organizer of value network

leveragability vs. the strategy of cannibalization
44
Trends of Telecommunication• From circuits to packets
• TCP/IP protocol & QoS challenges• DSP power & IPv6 compensate VoIP problem for
DiffServDiffServ• From electrical to optical transmission
