Film
and Digital Camera
The most notable difference is recording images because images on digital are captured on a sensor (a CCD or CMOS chip) then stored on a memory card or other media so it can transferred to computer and remove image from card to re-keep again for keep image again. Whereas, Images recorded on film comes in different sizes and varying sensitivities to light. These are not reusable and, except for a few APS cameras, once a film is removed you can't put it back to use up any unused film. Moreover, the number of the images on digital can be stored varies according to issues such as picture quality depending on capacity of memory card, otherwise, in general film can keep about 35-36 images per film.
Displaying of images is yet another difference to be considered. Digital camera can be displayed on the camera's LCD or on a PC or TV, depending on the camera. These are convenient to view and select favorite images to store in your digital camera. On the contrary, film camera cannot view the image by itself because it need to be processed professionally and delivered as prints and/or as digital files while digital camera can be printed at home with a suitable printer or printed professionally. In the part of editing image by the same program computer although the way to get it is different because camera can send via USB or memory card but film camera has to printed out, then scan to your computer.
In my opinion, some people are still buying film cameras because of the look and feel of film. Look at the difference between the motion pictures you go to that are shot on film versus shot on video. It's the same thing: film versus digital. Film photography has a life. Film photography is a living, breathing thing. Film pictures have more soul than digital ones. Film pictures have more depth; there's lighter, there's more action going on inside the image because film is a deeper, richer medium. You see much more shadow detail, much more highlight detail in film than you ever will in digital. Conversely, digital is cool, digital is convenient, digital is hot, digital makes beautiful big prints, but there's a look to film. Are regular people going to be shooting film as time goes on? Probably not. The artists, the serious photographers will, just like in the movie business, still shoot film instead of video, and that's because it's a different look; it's a different feel; it's a different medium.
Internet Connection
Communication via internet is increasing rapidly because it is easy to work and makes more benefits to the user. Thus, internet has become the world’s extensive, public communication system that now rivals the global telephone system in reach and range. It’s also the world’s largest implementation of client/server computing by linking people around the world can connection each other. The word Internet derives from the word internetworking or the linking of separate networks, each of which retains its own identity, into an interconnected network. There are several ways to access the Internet but the popular and easy to use ways can be classified into three accesses which are measured by performance such as personal area network is Dial-up internet access, local area network is Wi-Fi and the metropolitan area network is WiMax.
The first category is low speed internet such as Dial-up Internet connection because they typically have a maximum theoretical transfer speed of 56 Kbit/ by using the V.90 or V.92 protocol , although in most cases 40-50 Kbit/s is the norm. Factors such as phone line noise as well as the quality of the modem itself play a large part in determining connection speeds. Some connections may be as low as 20 Kbit/s in extremely noisy environments, such as in a dormitory where the phone line is shared with many extensions. Also an increasing amount of Internet content such as streaming media will not work at dialup speeds.
The second category is high speed internet such as Wi-Fi (wireless fidelity) Internet Connection. The family of Wi-Fi several standards but performance is similar so I will present the popular standard which are 802.11b and 802.11g standards. First, the 802.11 b standard is the first wireless standard that is widely adopted for wireless LANs and Internet access. They can transmit up to 11 Mbps in the unlicensed 2.4 GHz band and has effective distance of 30 to 50 meters, although this range can be extended outdoors by using tower-mounded antennas. Next, the 802.11g standard can transmit up to 54 Mbps in the 2.4 GHz range same as 802.11g so they are compatible because they operate in 2.4 GHz frequency. On the other hand, Wi-Fi performance in security is weak, which makes these wireless networks vulnerable to intruders and it is susceptible to interference from nearby system operating in the same spectrum such as wireless phone, microwave ovens or other wireless LANs.
The beginning of the internet connection use dial-up Internet because it is cheap and easy to use with telephone but a big drawback is noise and weather. They annoy the users so much, thus, wireless technology was developed which is Wi-Fi. It is the most popular in the world nowadays because it has high performance and low cost to installation and service. On the other hand, in the future we should keep an eye on WiMax because it is the newest technology which is the highest speed performance also can make communication is easier, faster and cheaper in far distance by technology device that can go anywhere. Thus, the chance to use wireless broadband which is the greatest in the world becomes true as soon as possible.
How
Computer Science is popular
Computer Science is a field that study about the structure of computer that cover from hardware to software .It is the study of principle and process of computing to determine which problems are (or are not) computable and design programming languages to enable the specification and expression of such algorithms. It design, evaluate, and build computer systems that can efficiently execute such specifications. Today, the innovations or inventions from computer move very fast and has become an important factor in our life. Thus, the students become more interesting in learning computer because after they graduated, the success is very interesting.
The first example is salary because many organizations or companies would like to employ professional people to improve and work for efficiency system. Especially, the area of computer jobs is very high salary as person who has good command will have higher salary than others. For instance, Salaries for computer programmers range from $45,000 for the lowest 10% to $130,000 or more for the top 10 percent. Average middle earnings in 2006 were around $65,000, which is a big money that makes people want to learn computer science.
logic or
mathematics and interested in writing program surely you can be a programmer.
Another choice, if you like computer graphic, animation or digital art
, graphic designer is appropriate to you. Moreover,
many students who graduate will have computer-related
careers in software engineering, system administration and management, research
and development in industrial and governmental laboratories. Since computer
technology can adapt to almost all fields, many students use their knowledge to
prepare themselves for many careers in other fields such as medicine, law,
education, physical and life sciences, social sciences, and humanities.
The second example is a variety of careers. The students that studies in computer science do not just work in computer scientist, but it have many choices to choose after they graduated. To illustrate, if you like communication and like to learn in computer network you can be Network Engineering. If you like The third example is important in business world because environment in daily life is one of effect to motivate student to learn about computer. Also any equipments, advertisements and all convenience things most related with technology it make computer science is increasing and help to improve economic as flow because new innovation that meet user requirement always make profits to their own business. A case in point is iPhone which is smart mobile consist of interesting feature by adding software to support comfortable to users so Apple company success in profits when the device is created. One of success reason comes from the knowledge of Steve Jobs that study about computer science.
From the three examples you will know the advantages of selecting to learn in Computer Science and answer the question how computer science is popular if you love to improve and solve problem by using computer to create different ideas. In my opinion this field is suitable for you because of besides can apply in your job it can help to apply in your daily life and more convenient for you.
Definition of web
Web stand for World Wide Web. In English, ‘www’ is pronounced “double-you double you double you” It is also interesting that in Mandarin Chinese, "World Wide Web" is commonly translated via a phono-semantic matching to wàn wéi wǎng which satisfies "www" and literally means "myriad dimensional net, " a translation that very appropriately reflects the design concept and proliferation of the World Wide Web. The web is a system of interlinked hypertext documents accessed via the Internet. Web browser can view Web pages that may contain text, images, video, and other multimedia and navigate between them using a hyperlink which is a reference, link or navigator element in their page to another section of the same page. Moreover, Worldwide Web was the first web browser and WYSIWYG HTML editor and introduced in 1989 by Tim Berners-Lee or British scientist. Now, the web is developed to web 2.0 and web 3.0 which enable spread information over the Internet through an easy-to-use and flexible format.
Web 2.0 describes the changing trends in using the World Wide Web technology and web design that makes more interesting creativity, communications,
security for sharing information and functionality of the web. The concept has guided the development and evolution of web culture communication and hosted service such as social-networking sites, video sharing sites, wikis, blogs and social classification. Also, web 2.0 refers to “the business revolution in computer world caused by moving to the Internet as a platform, and an attempt to understand the rules for success on that new platform.” The mentioned meaning is defined by Tim, the inventor of the World Wide Web.
The web inventor provided the examples of companies or products that embody the principles in four levels in the hierarchy of Web 2.0 sites. First, Level 3 application, the aims exist only on the Internet, derive their effectiveness between human connections and from network effect that Web2.0 can active, and grow in effectiveness in proportion that people make more use of them such as eBay ,Skype ,Craigslist, dodgeball and Wikipedia etc. Second is Level 2 application can operate offline but it has an advantage from obtain online such as Flickr or Photobucket which has benefit from its shared photo-database and from community –generated
tag database. Next, Level 1 application operates offline but obtain feature online. It may be focused in Writely such as Google Docs or Spreadsheet and iTunes because of its music-store portion. Last, Lever 0 applications work as offline well as online such as MapQuest, Yahoo! and Google Maps. However Non-web applications like e-mail, instant-messaging clients, and the telephone fall outside the above hierarchy.
The technology world is always improving and making more benefit for the user thus web 3.0 is released to support the requirements of the user. The web 3.0 is one of the terms used to describe the evolution stage of Web that follows Web 2.0.
Given that technical and social possibilities identified in this latter term are yet to be fully realized the nature of defining Web 3.0 is highly speculative. In general, it refers to the view of the internets which, though potentially possible, are not technically or practically feasible at this time. Web 3.0 has also been using semantic web, microformats, natural language search, data mining, machine learning, recommendation agents, and leading to new possibility in artificial intelligence technologies which emphasize machine-facilitated understanding of information in order to provide a more productive and instinctive user experience.
Following the definition of the phrase “Web 2.0” as a description of the recent evolution of the Web but the term “Web 3.0” has been introduced to hypothesize about a future wave of Internet innovation. Views on the next stage of the World Wide Web’s evolution vary greatly because web 3.0 has increased Internet connection speed, modular web application, and advance in computer graphics that is the important thing in the evolution of the World Wide Web. Thus, we should keep an eye on new innovation that is released from web 3.0 shortly which will lead to the third generation and the user will gain more benefit from the web.
In 1996, Macromedia was established by Macromedia and currently developed and distributed by Adobe Systems. Flash is a set of multimedia software which included a combination of text, audio, still images, animation, video and interactivity content forms. These several media make flash became popular in creating animation, advertisement, and various web page components, in integrating video in web, and more recently in developing Internet application.
The program Flash was the brainchild of Jonathan Gay, who developed the idea while in college and extended it while working for Silicon Beach Software and its successors. As a child, he grew up playing with LEGOs that was inspired his idea to develop Flash because LEGOs can build any figure with his own design especially a house or a building. Until he grew older he try to develop an interest in architecture. About that time, he used an Apple II computer to write his first graphic editor. He did pretty well so he decided to walk in to Silicon Beach Software in order to begin a job while he was just a high school student. He began writing games. First is Airborne! then Dark Castel. The second game made him could hit through college. He said writing games was an important part of the computer education and the beginning of his inspiration for Flash because he had a chance to learn about animation, digitized sound, and how to synchronize the two.
After the games, he
returned to building graphics editors by making a product for Macintosh called
SuperPaint. After graduation, he designed to draw program called Intellidraw
for Aldus. This program makes many profit
and a modest success,thus,in January 1993, Jonathan Gay, Charlie
Jackson, and Michelle Welsh started a small software company called
FutureWaveSoftwareand created their first product, SmartSketch. A drawing
application, SmartSketch was designed to make creating computer graphics as
simple as drawing on paper. At first it did not gain popularity so they realize
the possibility for a vector-based web animation tool. Therefore, the company
added frame-by-frame animation feature and released it to FutureSplash Animator
on Macintosh and PC. With six people in the company, the product was offered to
Adobe and used by Microsoft in its early work with the Internet. Then in
December 1996 Macromedia Company required using his software and later released
it as Flash contracting “Future” and “Splash” of the FutureWave name.
FutureSplashAnimator is the initial version of Flash with basic editing tools andtimeline since April10, 1996. It was used on several big-name websites such as Microsoft’s MSN, Fox’s Official and Disney website and in November 1996, a Macromedia re-branded version of FutureSplashAnimator. Flash continue being popularuntil in 2003, Macromedia Flash MX Professional 2004. It developed in several features such as screen which is formed for non-linear state-based development and slide for organize in a linear slide format like PowerPoint, webservices integration, video import wizard, Media Playback components. It included a complete MP3 and FLV player in a component that may be placed in an SWF format. In the current version,
Adobe Flash CS3 Professional is released in April 16, 2007. It is the first version of Flash released under the Adobe name. CS3 feature adds better integration with other Adobe products such as Adobe Photoshop, and also provides better Vector drawing behavior, becoming more like Adobe Illustrator and Adobe Fireworks.
Nowadays, Adobe Flash is a main program for the Internet world so Adobe Flash provide ‘Flash player’ program to supporting any tactics by using to plug-in inside web browsers for Flash can be used such as game flash,advertising flash,etc. Adobe Flash is not only using in computer because now it is coming to the iPhone. That means Flash become important technology that makes imagination and new design in creating. Thus, we should thanks Jonathan Gay for capability to creating intelligence program which can make any advantage to users in currently.
In 2001, the intelligent operating system Windows XP was established by Microsoft
Company. The name XP stands for eXPerience to use on personal computer including homes, business desktops, and notebook computers. It becomes a new innovation and replaces Windows 2000 and Windows ME as rapidly as a rocket. The most common edition of this operating system is Windows XP HOME Edition. Besides, Windows XP Professional is adding more function which is targeted at power user, business and enterprise group.
Furthermore, the user interface is the interesting tactic that is added from the old edition.
At present, Windows XP is developed to many editions and each version has different themes or features such as Dark edition, Gold edition, and Starter edition which is release for first time users. On the other hand, authenticity or Windows Genuine is not popular because of high price, so illegal license becomes normal because it easy to copy and hard to detect. Also, illegal copy can do any functions and features similar as the genuine one. However, either genuine or unreal is defined in Windows XP so it may not be surprising if we admire the Windows XP to be the most necessary component in your computer that gives high benefits for you.
