สรุป บทที่1 โครงสร้างข้อมูลและขั้นตอนวิธี

1. ความหมายของโครงสร้างข้อมูล

         โครงสร้างข้อมูล < Data Structure > คือความสัมพันธุ์ระหว่างข้อมูลที่อยู่

ในโครงสร้างนั้นๆ รวมทั้งกระบวณการในการจัดการข้อมูลในโครงสร้าง เช่น

 เพิ่ม แก้ไข ลบ


2. ประเภทของโครงสร้างข้อมูล

         โครงสร้างข้อมูลในภาษาคอมพิวเตอร์ แบ่งออกเป็น 2 ประเภท

(1).โครงสร้างข้อมูลเชิงกายภาพ < Physical data structure > เป็นข้อมูลดิบ,

ข้อมูลที่พบเห็นได้ทั้วไป

§  ข้อมูลเบื้องต้น ได้แก่ จำนวนเต็ม จำนวนจริง ตัวอักษร
§  ข้อมูลโครงสร้าง ได้แก่ แถวลำดับ ระเบียบข้อมูล แฟ้มข้อมูล เป็นต้น
(2).โครงสร้างข้อมูลทางตรรกะ < Logical data structure > ข้อมูลที่ถูกการ

ประมวลผลโดยผ่านกระบวณการคิดมาแล้ว

§  โครงสร้างข้อมูลเชิงเส้น ได้แก่ ลิสต์ แสตก คิว สตริง
§  โครงสร้างข้อมูลแบบไม่เชิงเส้น ได้แก่ ทรี กราฟ
3. การแทนที่ข้อมูลในหน่วยความจำหลัก          
            1. การแทนที่ข้อมูลแบบสแตติก (Satatic Memory Representationคือ ไม่สามารถปรับขนาดหรือเพิ่มลดได้             
            2. การแทนที่ข้อมูลแบบไดนามิก (Dynamic Memory Representation) คือ เป็นการแทนที่ข้อมูลที่ไม่ต้องจองเนื้อที่ ขนาดของเนื้อที่สามาถยืดหยุ่นได้

4.ขั้นตอนวิธี Algorithm

          เป็นวิธีการแก้ไขปัญหาต่างๆ อย่างมีระบบมีลำดับขั้นตอนตั้งแต่ต้นจน

กระทั่งได้ผลลัพธ์ สามารถเขียนได้หลายแบบ การเลือกใช้ต้องเลือกใช้วิธีขั้น

ตอนที่เหมาะสมกระชับและรัดกุม

History Of  B M W

Bayerische Motoren Werke AG (BMW),  is a German automobile, motorcycle and engine manufacturing company founded in 1916. It also owns and produces the Mini brand, and is the parent company of Rolls-Royce Motor Cars. BMW produces motorcycles under BMW Motorrad and Husqvarna brands.     BMW is known for its performance and luxury vehicles, and is in fact global leader in premium car sales.

BMW is an acronym for Bayerische Motoren Werke AG — or, in English, Bavarian Motor Works. Whatever you call it, the German-based company is one of the world's most respected automakers, renowned for crafting luxury cars and SUVs that offer superior levels of driving enjoyment.

Founded in Munich, the company began in the early 1910s as an aircraft manufacturer. BMW's current logo, designed to represent white propeller blades against a blue sky, reflects these origins; its blue-and-white color scheme also references Bavaria's blue-and-white checkered flag.

It wasn't until 1928 that production began on the first BMW automobile, the Dixi. The car proved tremendously popular, and its success helped the manufacturer weather the Depression. BMW's best-known pre-World War II vehicle was the Type 328 roadster, a supple two-seater that racked up over 120 victories on the motorsport circuit between 1936 and 1940. Postwar BMW cars maintained this tradition, winning several racing, rallying and hill climb victories.

The early 1950s saw the launch of the BMW 501, a roomy, voluptuous sedan that was resplendent with all of the hopefulness of that era. It was soon followed by the 502 which was powered by the world's first light-alloy V8, foreshadowing BMW's ongoing commitment to developing new technology. The best-selling BMW of that decade was the Isetta, a petite two-seat "microcar" typically powered by a 12- or 13-horsepower engine. The mid-'50s also saw the debut of the limited production and breathtakingly beautiful 507 sports car which had an alloy body and used the 502's V8 for propulsion. In the 1960s, BMW sales strengthened significantly, thanks in part to the immense popularity of the 1500, a sporty family sedan.

By the 1970s, BMW was establishing itself as a full-fledged car company. It was a pioneer for many emerging technologies, including turbocharging and advanced vehicle electronics. BMW of North America was established at this time, and consumers who coveted both sports and luxury cars became loyal "Bimmer" owners. The '70s also saw the birth of BMW's three-tier sport sedan range consisting of the compact 3 Series, midsize 5 Series and large 7 Series cars and the creation of its performance M division. Though the 3 Series could be had with four-cylinder power, it was the company's inline-6 engines that developed BMW's reputation for spirited, yet highly refined performance. At decade's end, the limited-production, short-lived M1 supercar debuted.

Throughout the 1980s, BMW became the unofficial poster car of yuppies, as the brand ostensibly signified one's financial success as well as a passion for driving. The elegant 6 Series coupe debuted and the latter part of the decade saw the high-performance M division working its magic on various production models.

The early 1990s saw BMW replace the 6 Series with the powerful (V12-powered at first) but heavy 8 Series grand touring coupe while later that decade the Z3 roadster bowed. The company also opened its first U.S. manufacturing plant in the latter half of the 1990s.

The 2000s brought a midsize SUV (the X5) as well as a compact SUV (the X3) as BMW joined the hot-selling segment. Since then, BMW has replaced the Z3 with the Z4, introduced the compact 1 Series, produced hybrid versions of a few models and debuted the X6 fastback crossover. The company has also expanded its empire to include Mini and Rolls-Royce and continues to build motorcycles, something it has done since the 1920s.

The automaker's famous advertising slogan describes each of its vehicles as "the ultimate driving machine," and it's not mere hyperbole. Over the past couple of decades, BMWs have become the standard for performance and luxury in most of the "over $30,000" segments. With family-friendly wagons, crisp sedans, distinctive coupes, nimble sports cars and spacious SUVs offered, BMW's model roster is diverse. But its luxury vehicles all share a common characteristic: the ability to make drivers feel gloriously connected to the road.

                                                                                               


Product

Zippo

Zippo was founded in Bradford, Pennsylvania in 1932 when George G. Blaisdell decided to create a lighter that would look good and be easy to use. Blaisdell obtained the rights for an Austrian windproof lighter with a removable top, and re-designed it to his own requirements. He made the case rectangular and attached the lid to the bottom with a welded hinge, and surrounded the wick with a windhood. Fascinated by another recent invention, the zipper, Blaisdell called his new lighter "Zippo", and backed it with a Lifetime Guarantee.


Today Zippo has produced over 325 million windproof lighters since its founding in 1932. Except for improvements in the flint wheel and modifications in case finishes, Blaisdell's original design remains virtually unchanged today. The Lifetime Guarantee that accompanies every Zippo metal product still guarantees that "It works or we fix it free".

Although the windproof lighter is the most popular Zippo product, Zippo took its first step toward diversification with the introduction of a six-foot flexible steel pocket tape measure in 1962. The success of this product led Zippo to expand the line to its current product family of tape measures, pocket knives, money clips, writing instruments, key holders, ZipLight™ pocket flashlights and the Fixxit™ pocket tool. Today, all of these items can be imprinted with company logos or trademarks.
