1. 1) NATURE OF COMPUTER TECHNOLOGY HAS CHANGED A LOT IN THE
PAST 10 YEARS AND WILL CHANGE A LOT IN THE NEXT 10 YEARS.
2) MOST OF YOU IN 1991 HAD NOT EVEN HEARD OF INTERNET
,WORLD-WIDE WEB ,NETWORKS, PERSONAL DIGITAL ASSISTANT
(PDA),WINDOWS NT , LINUX.
3) THESE ARE ALL NOW PART OF COMPUTER TECHNOLOGY AND
INTERNET TECHNOLOGY.
NETWORKING TECHNOLOGY
WAY TO CONNECT COMPUTERS IN HOME OR OFFICE USING ELECTRICAL
WIRING.
NETWORKING POWER LINE
1) MORE CONVENIENT THAN PHONE LINES
2) DATA TRAVELS THROUGH ELECTRICAL WIRING.
3) REQUIRE NO NEW WIRING AND ADDS NO COST TO ELECTRIC BILL.
Computer and InternetTechnology Development and its
Impact on OtherTechnologies

2. Computer and Internet Technology Development and its Impact
on Other Technology
Wireless Networking Bluetooth
 Creates network by sending
infrared or radio signals
between computers
 Better than Power-line
networking; some computers
are not “plugged in” to
electrical outlet
 Laptop with wireless network
card is completely portable
throughout home or office.
 Infrared is almost always “one
to one” technology
 Bluetooth is new standard being
developed by a group of
electronics manufacturer
 Will allow any sort of electronic
equipment to communicate with
each other.
 Can be used among computers ,
keyboard , mouse , cell phone
 Bluetooth-like radio
communications should take
place of wires or infrared signals
for connecting devices.

3. Computer and Internet Technology Development and its Impact
on Other Technology
Airborne Internet Impact and Opportunity
 Satellite Internet access
already commonplace .
 Satellite orbit at several
hundreds of miles above
Earth.
 Imagine airplane-like
device at approximately
60,000 feet.
 Impact : possibility of
constant connection to
network anywhere, any time.
 Benefit: Ease of connecting
all computers and related
devices .
 Challenges : How to make
most efficient use of the
computing power , software ,
and tools always available .

4. Computer and Internet Technology Development and its Impact
on Other Technology
The Next Generation Internet
Internet Protocol Version 6
(IPv6)
 Larger bandwidth
 Faster Speeds
 Better Reliability
 Better Compression
techniques ( smaller files to
be transmitted )
 IPv6 fixes a number of
problems in IPv4 , such as
limited no. of available
IPv4 addresses.
 IPv6 goes from 32 to 128
bits per address
 If whole Earth was a beech
, more than enough IP
addresses for every grain
of sand…hope that will be
enough
