2) History and Future of Computing
3) IS in Business• chapters 1 and 2
What do you know?What do you know?What is a CRM?
Is IT moving to "The Cloud?"
What is "net neutrality"?
Is telecommuting an effective business practice?
Does a customer have a legal right to privacy?
Dannelly's Short Dannelly's Short HistoryHistoryof Computingof Computing
Charles Babbage Charles Babbage (1791-1871)(1791-1871)
Math Tables Problem
Difference Engine and Analytical Engines◦Abilities
add subtract loop conditional branch etc…
◦instructions and dataon punched cards
Harvard Mark 1Harvard Mark 1mechanicalcompleted in 1943used to compute artillery tablesinstructions on paper tapestorage = 72 registers
Digital Electronics 101Digital Electronics 101circuits are a series of "gates" or
switchesgates can perform AND, OR, NOT,
etcExample - Half Adder:
AND
XOR
Apple's iPad uses theA4 system chip with
177 million transistors
First GenerationFirst Generationbased on vacuum tubes
ENIAC◦ 1946 - Univ of Pennsylvania◦ base 10, not binary◦ programmed via wires
UNIVAC◦ 1951◦ first commercial machine
Second GenerationSecond Generationbased on transistors1955-1964FORTRAN and COBOL
This IBM 1301 Disk Storage Unitheld 2.8 MB of data.
Lease = $2100 per monthThe IBM 1401 Mainframe leased for
about $2500 per month in 1960.
Third GenerationThird Generationbased on Integrated Circuitsmainframes and minicomputers
◦IBM 360 1964 equally suited for business or science from 8K to 8M of memory
Fourth GenerationFourth Generationbased on VLSImicrocomputers
◦IBM PC released in 1981
Fifth GenerationFifth Generationhas not officially happened yet
maybe it was the internet-ization of every device
maybe it was mobile-ization of every device, thanks to Lithium-Ion batteries allowing smaller devices

Stages of a New Stages of a New Technology becoming Technology becoming ViableViable1. Critical Price2. Critical Mass3. Displacement of Another Technology4. Nearly Free
Example : Voice Over IP1. high speed internet connection cost less $2. over 20% of households get high speed3. international calls made over internet4. talking to someone in India near free via Skype

Near Future:Near Future:
The CloudThe Cloud
Cloud computing refers to the on-demand provision of computational resources (data, software) via a computer network, rather than from a local computer.

Possible Future :Possible Future :Quantum ComputingQuantum ComputingClassical Mechanics
• an object in motion stays in motion blah blah
Quantum Mechanics• a particle can be in two places at once• two particles can be "entangled" regardless of distance or time• there are parallel universes
Quantum Computer• based on Qubits• can be 1, or 0, or 1 and 0 at the same time• computational complexity is no longer relevant• data transfer would be instant• very good at decoding encrypted messages• Oxford has an 8 qubit computer
So what?So what?
What trends do you see in that history?1.smaller, cheaper, more smart devices used
for more things2.moving from Mainframes to PCs to Cloud
So what does that mean for the future?◦consumers?◦businesses?
as of May 2010, Apple is worth more than Microsoft
