3)
IS in Business
• chapters 1 and 2
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 History
of Computing
Charles Babbage
(1791-1871)
Math Tables Problem
Difference Engine and Analytical Engines
◦ Abilities
add
subtract
loop
conditional branch
etc…
◦ instructions and data
on punched cards
Harvard Mark 1
mechanical
completed in 1943
used to compute artillery tables
instructions on paper tape
storage = 72 registers
Digital Electronics 101
circuits are a series of "gates" or switches
gates can perform AND, OR, NOT, etc
Example - Half Adder:
XOR
AND
Apple's iPad uses the
A4 system chip with
177 million transistors
First Generation
based on vacuum tubes
ENIAC
◦ 1946 - Univ of Pennsylvania
◦ base 10, not binary
◦ programmed via wires
UNIVAC
◦ 1951
◦ first commercial machine
Second Generation
based on transistors
1955-1964
FORTRAN and COBOL
The IBM 1401 Mainframe leased for
about $2500 per month in 1960.
This IBM 1301 Disk Storage Unit
held 2.8 MB of data.
Lease = $2100 per month
Third Generation
based on Integrated Circuits
mainframes and minicomputers
◦ IBM 360
1964
equally suited for business or science
from 8K to 8M of memory
Fourth Generation
based on VLSI
microcomputers
◦ IBM PC released in 1981
Fifth Generation
has 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 Technology
becoming Viable
1.

Critical Price
Critical Mass
Displacement of Another Technology
Nearly Free
Example : Voice Over IP
1.

4.
high speed internet connection cost less $
over 20% of households get high speed
international calls made over internet
talking to someone in India near free via Skype

Near Future:
The Cloud
Cloud computing refers to the on-demand provision of
computational resources (data, software) via a
computer network, rather than from a local computer.
-- http://en.wikipedia.org/wiki/Cloud_computing
Possible Future :
Quantum Computing
Classical 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?
What trends do you see in that history?
smaller, cheaper, more smart devices used
for more things
2. moving from Mainframes to PCs to Cloud
1.
So what does that mean for the future?
◦ consumers?
◦ businesses?
as of May 2010, Apple is worth more than Microsoft
