Biography of Steve Jobs, Co-Founder of Apple Computers

Biography of Steve Jobs, Co-Founder of Apple Computers Steve Jobs (February 24, 1955–October 5, 2011) is best remembered as the co-founder of Apple Computers. He teamed up with inventor  Steve Wozniak to create one of the first ready-made PCs. Besides his legacy with Apple, Jobs was also a smart businessman who became a multimillionaire before the age of 30. In 1984, he founded NeXT computers. In 1986, he bought the computer graphics division of Lucasfilm Ltd. and started Pixar Animation Studios. Fast Facts: Steve Jobs Known For: Co-founding Apple Computer Company and playing a pioneering role in the development of personal computingAlso Known As: Steven Paul JobsBorn: February 24, 1955 in San Francisco, CaliforniaParents: Abdulfattah Jandali and Joanne Schieble (biological parents); Paul Jobs and Clara Hagopian (adoptive parents)Died: October 5, 2011 in Palo Alto, CaliforniaEducation: Reed CollegeAwards and Honors: National Medal of Technology  (with  Steve Wozniak), Jefferson Award for Public Service,  named the most powerful person in business by Fortune  magazine,  Inducted into the  California Hall of Fame, inducted as a  Disney LegendSpouse: Laurene PowellChildren: Lisa (by Chrisann Brennan), Reed, Erin, EveNotable Quote: Of all the inventions of humans, the computer is going to rank near or at the top as history unfolds and we look back. It is the most awesome tool that we have ever invented. I feel incredibly lucky to be at exactly the right place in  Silicon Valley, at  e xactly the right time, historically, where this invention has taken form. Early Life Jobs was born on February 24, 1955, in San Francisco, California. The biological child of Abdulfattah Jandali and Joanne Schieble, he was later adopted by Paul Jobs and Clara Hagopian. During his high school years, Jobs worked summers at Hewlett-Packard. It was there that he first met and became partners with Steve Wozniak. As an undergraduate, he studied physics, literature, and poetry at Reed College in Portland, Oregon.  Formally, he only attended one semester there. However, he remained at Reed and crashed on friends sofas and audited courses that included a calligraphy class, which he attributes as being the reason Apple computers had such elegant typefaces. Atari After leaving Oregon in 1974 to  return to California, Jobs started working for Atari, an early pioneer in the manufacturing of personal computers. Jobs close friend  Wozniak was also working for Atari. The future founders of Apple teamed up to design games for Atari computers. Hacking Jobs and Wozniak proved their skills as hackers by designing a telephone blue box. A blue box was an electronic device that simulated a telephone operators dialing console and provided the user with free phone calls. Jobs spent plenty of time at Wozniaks Homebrew Computer Club, a haven for computer geeks and a source of invaluable information about the field of personal computers. Out of Mom and Pops Garage By the late 1970s, Jobs and Wozniak had learned enough to try their hand at building personal computers. Using Jobs family garage as a base of operation, the team produced 50 fully assembled computers that were sold to a local Mountain View electronics store called the Byte Shop. The sale encouraged the pair to start Apple Computer, Inc. on April 1, 1979. Apple Corporation The Apple Corporation was named after  Jobs favorite fruit. The Apple logo was a representation of the fruit with a bite taken out of it. The bite represented a play on words: bite and byte. Jobs co-invented the  Apple I  and  Apple II  computers together with  Wozniak, who was the main designer, and others. The Apple II is  considered to be  one of the first commercially successful lines of personal computers. In 1984, Wozniak, Jobs, and others co-invented the  Apple Macintosh  computer, the first  successful home computer with a mouse-driven graphical user interface. It was, however, based on (or, according to some sources, stolen from) the Xerox Alto, a concept machine built at the Xerox PARC research facility. According to the Computer History Museum, the Alto included: A mouse. Removable data storage. Networking. A visual user interface. Easy-to-use graphics software. â€Å"What You See Is What You Get† (WYSIWYG) printing, with printed documents matching what users saw on screen. E-mail. Alto for the first time combined these and other now-familiar elements in one small computer. During the early 1980s, Jobs controlled the business side of the Apple Corporation. Steve Wozniak was in charge of the design side. However, a power struggle with the board of directors led to Jobs leaving Apple in 1985. NeXT After leaving Apple,  Jobs founded NeXT, a high-end computer company. Ironically, Apple bought NeXT in 1996 and Jobs returned to his old company to serve once more as its CEO from 1997 until his retirement in 2011. The NeXT was an impressive workstation computer that sold poorly. The worlds first web browser was created on a NeXT, and the technology in NeXT software was transferred to the Macintosh and the iPhone. Disney Pixar In 1986, Jobs bought The Graphics Group from Lucasfilms computer graphics division for $10 million. The company was later renamed Pixar. At first, Jobs intended for  Pixar to become a high-end graphics hardware developer, but that goal was never met.  Pixar moved on to do what it now does best, which is make animated films. Jobs negotiated a deal to allow Pixar and Disney to collaborate on a number of animated projects that included the film Toy Story. In 2006, Disney bought Pixar from  Jobs. Expanding Apple After Jobs returned to Apple as its CEO in 1997, Apple Computers had a renaissance in product development with the iMac, iPod, iPhone, iPad, and more. Before his death, Jobs was listed as the inventor and/or co-inventor on 342 United States patents, with technologies ranging from computer and portable devices to user interfaces, speakers, keyboards, power adapters, staircases, clasps, sleeves, lanyards, and packages. His last patent was issued for the Mac OS X Dock user interface and was granted the day before his death. Death Steve Jobs died at his home in Palo Alto, California, on October 5, 2011. He had been ill for a long time with pancreatic cancer, which he had treated using alternative techniques. His family reported that his final words were, Oh wow. Oh wow. Oh wow. Legacy Steve Jobs was a true computer pioneer and entrepreneur whose impact is felt in almost every aspect of contemporary business, communication, and design. Jobs was absolutely dedicated to every detail of his products- according to some sources, he was obsessive- but the outcome can be seen in the sleek, user-friendly, future-facing designs of Apple products from the very start. It was Apple that placed the PC on every desk, provided digital tools for design and creativity, and pushed forward the ubiquitous smartphone which has, arguably, changed the ways in which humans think, create, and interact.

Life In A Temperate Grassland

Life In A Temperate Grassland As much as one-fifth of the Earths surface is covered in wild grasses in biomes known, aptly, as grasslands. These biomes are characterized by the plants that grow there, but they also attract a unique array of animals into their realm.   Savannas and Grasslands: Whats the difference? Both are dominated by grass and few trees as well as hooved animals that can run fast from predators, so whats the difference between a grassland and a savanna? Essentially a savanna is one type of grassland found in tropical regions. It generally gets more moisture and therefore has a few more trees than grasslands in the rest of the world. The other type of grassland - known more simply as a temperate grassland - experiences seasonal changes throughout the year that bring hot summers and cold winters. Temperate grasslands receive just enough moisture to support the growth of grasses, flowers, and herbs, but not much else. This article will focus on the plants, animals, and regions of the worlds temperate grassland biomes. Where in the World Are Grasslands Found? Temperate grasslands are characterized by their  hot summers, cold winters, and very rich soils. They  can be found throughout North America - from Canadas prairies to the plains of the midwestern United States. They are also found in other parts of the world, albeit they are known here under different names. In South America, grasslands are called pampas, in Hungary they are called pusztas, whereas in Eurasia they are known as steppes. Temperate grasslands found in South Africa are called veldts. Plants in the Grassland: More than just grass! As you might expect, grasses are the predominant plant species growing in grasslands. Grasses, such as barley, buffalo grass, pampas grass, purple needlegrass, foxtail, rye grass, wild oats, and wheat are the main plants that grow in these ecosystems. The amount of annual rainfall affects the height of the grasses that grow in temperate grasslands, with taller grasses growing in wetter areas. But thats all there is to these rich and fertile ecosystems. Flowers, such as sunflowers, goldenrods, clover, wild indigos, asters, and blazing stars make their home among those grasses, as do several species of herbs. Precipitation in grassland biomes is often high enough to support grasses and a few small trees, but for the most part trees are rare. Fires and erratic climate generally prevent trees and forests from taking over. With so much of a grass growth occurring underground or low to the ground, they are able to survive and recover from fires more quickly than shrubs and trees. Also, the soils in grasslands, while fertile, are typically thin and dry, making it difficult for trees to survive. Temperate Grassland Animals There are not many places for prey animals to hide from predators in grasslands. Unlike savannas, where there is a large diversity of animals present, temperate grasslands are generally dominated by just a few species of herbivores such as  bison, rabbits, deer, antelope, gophers, prairie dogs,and antelopes. Since there are not many places to hide in all of that grass, some grassland species - such as mice, prairie dogs, and gophers have adapted by digging burrows to hide from predators such as coyotes and foxes.  Birds such as eagles, hawks, and owls also find lots of easy prey in grasslands. Spiders and insects, namely grasshoppers, butterflies, crickets, and dung beetles are in abundance in temperate grasslands as are several snake species. Threats to Grasslands The primary threat faces by grassland ecosystems is the destruction of their habitat for agricultural use. Thanks to their rich soils, temperate grasslands are frequently converted to farm land. Agricultural crops, such as corn, wheat, and other grains grow well in grassland soils and climate. And domestic animals, such as sheep and cattle, love to graze there. But this destroys the delicate balance of the ecosystem and removes the habitat for the animals and other plants that call the temperate grasslands their home. Finding land to grow crops and support farm animals is important, but so are grasslands, and the plants and animals that live there.
