When the market received the IBM PC bang in the mid-1980, Microsoft, thanks to IBM came up with MS-DOS. The runner up was Digital Research. So, in August 12, 1981 Microsoft starts working at MS-DOS. They started from a clone of QDOS for which they paid $50000, clone renamed as PC-DOS.
But MS-DOS got alive only thanks to COMPAQ who managed to clone the IBM BIOS and so the world got a new player on the computer manufacturers. Thanks to this, Microsoft began licensing its operating system for use on non-IBM PC clones and so MS-DOS (Microsoft Disk Operating System) entered the scene.
In 1985, Microsoft moves to Ireland and there they founded the first international production facility. And there, on November 20 Microsoft released its first retail version of Microsoft Windows, originally a graphical extension for its MS-DOS operating system. In August, Microsoft and IBM partnered in the development of a different operating system called 0S/2. OS/2 was marketed in connection with a new hardware design proprietary to IBM, the PS/2. Shortly afterwards on February 16, 1986, Microsoft relocated to Redmond, Washington. Around one month later, on March 13, the company went public with an IPO, raising US$61 million at US$21.00 per share. By the end of the trading day, the price had risen to US$28.00. In 1987, Microsoft eventually released their first version of OS/2 to OEMS.
The early versions of Windows were often thought of as just graphical user interfaces or desktops, mostly because they were started from MS-DOS and used it for file system services. However even the carliest 16-bit Windows versions already assumed many typical operating system functions, notably having their own executable file format and providing their own device drivers (timer, graphics, printer, mouse, keyboard and sound) for applications. Unlike DOS, Windows allowed users to execute multiple graphical applications at the same time, through co-operative multitasking, something which competitors (like GEM) did not offer. Finally, Windows implemented an elaborate, segment-based, software virtual memory scheme which allowed it to run applications larger than available memory: code segments and resources were swapped in and thrown away when memory became scarce, and data segments moved in memory when a given application had relinquished processor control, typically waiting for user input. Examples include Windows 1.0 (1985) and Windows 2.0 (1987) and its close relative Windows/286.

REPORT: BIOFUELS POISED TO DISPLACE OIL
Biofuels such as ethanol and biodiesel can
significantly reduce global dependence on oil, according
to a new report by the Worldwatch Institute.
Last year, world biofuel production surpassed 670,000
5 barrels per day, the equivalent of about 1 percent of the
global transport fuel market. Although oil still accounts for
more than 96 percent of transport fuel use, biofuel
production has doubled since 2001 and is poised for even
stronger growth as the industry responds to higher fuel
10 prices and supportive government policies. “Coordinated
action to expand biofuel markets and advance new
technologies could relieve pressure on oil prices while
strengthening agricultural economies and reducing climatealtering
emissions,” says Worldwatch Institute President
15 Christopher Flavin.
Brazil is the world’s biofuel leader, with half of its
sugar cane crop providing more than 40 percent of its nondiesel
transport fuel. In the United States, where 15 percent
of the corn crop provides about 2 percent of the non-diesel
20 transport fuel, ethanol production is growing even more
rapidly. This surging growth may allow the U.S. to overtake
Brazil as the world’s biofuel leader this year. Both countries
are now estimated to be producing ethanol at less than
the current cost of gasoline.
25 Figures cited in the report reveal that biofuels could
provide 37 percent of U.S. transport fuel within the next 25
years, and up to 75 percent if automobile fuel economy
doubles. Biofuels could replace 20–30 percent of the oil
used in European Union countries during the same time
30 frame.
As the first-ever global assessment of the potential
social and environmental impacts of biofuels, Biofuels for
Transportation warns that the large-scale use of biofuels
carries significant agricultural and ecological risks. “It is
35 essential that government incentives be used to minimize
competition between food and fuel crops and to discourage
expansion onto ecologically valuable lands,” says
Worldwatch Biofuels Project Manager Suzanne Hunt.
However, the report also finds that biofuels have the potential
40 to increase energy security, create new economic
opportunities in rural areas, and reduce local pollution and
emissions of greenhouse gases.
The long-term potential of biofuels is in the use of
non-food feedstock that include agricultural, municipal, and
45 forestry wastes as well as fast-growing, cellulose-rich
energy crops such as switchgrass. It is expected that the
combination of cellulosic biomass resources and “nextgeneration”
biofuel conversion technologies will compete
with conventional gasoline and diesel fuel without subsidies
50 in the medium term.
The report recommends policies to accelerate the
development of biofuels, while maximizing the benefits and
minimizing the risks. Recommendations include:
strengthening the market (i.e. focusing on market
55 development, infrastructure development, and the building
of transportation fleets that are able to use the new fuels),
speeding the transition to next-generation
technologies allowing for dramatically increased
production at lower cost, and facilitating sustainable
60 international biofuel trade, developing a true
international market unimpeded by the trade restrictions
in place today.

Learning to quit
Jodi Hall started smoking at age 9.
By the time she was 16, she was up to a pack a day – and she wanted to quit. A couple of reasons: one, her health; two, a guy named Mony. “He said that when he kissed me, it was like kissing an ashtray”, Jodi says.
Earlier this year, Jodi, along with 25 of her classmates at Johnson High School, in Savannah, GA, enrolled in the school’s first stop-smoking class. During the eight-week Tobacco Free Teen class, they learned what smoking can do to their body, their wallet and their grades (some kids end up cutting class to satisfy their nicotine cravings). But it wasn’t just about scare tactics. The goal is behavior modification, not punishment, so students are taught techniques for handling stress and resisting the urge to light up even when friends or parents do.
According to the American Lung Association (ALA), which sponsors the class, about half the adults who smoke were regular smokers by age 18. “Theses numbers are only going to get worse,” says Kristine Lewis of the ALA. “The tobacco industry is turning to teens.”
How did the students do? Jodi has been cigaretteless for three months. But she’s the only one. Her classmate Adam Cushman is slowly putting his way back to three packs a day. The 16-year-old says he wants to stop, “but the way things are going, I doubt I’ll be able to.”
Seventeen, June 1996.
The word goal in “The goal is behavior modification” can be replaced by:
