History and Development of USB Technology

History And Development of USB TechnologyWe certainly are familiar with USB technology, either on your computer or other technological devices, such as DVD Player, HiFi Compo, and so forth. From start to USB 1.0 to USB 2.0, we would've never tried it. In that sense the field of IT, its own USB stands for Universal Serial Bus, which with this technology we can connect many many peripherals and other devices into the computer.USB has the ability to plug 'n' play and also supports "hot swapping", where we can remove or install other devices through the connector without having to reboot. Another feature of the USB that we can get the power required is very small and we do not require additional power again.
USB early history began in 1996. In this, the USB version 1.0 was introduced. Some large companies are creating USB technology, among others, Intel, Compaq, Digital, IBM, and Northern Telecom, where each has its own role in creating the USB technology. As Intel by producing a UHCI host controller and open software stack, Microsoft produced a USB software stack for Windows and with National Semiconductor and Compaq participate formulate OHCI host controller. Philips-did not want to miss, they produced the first USB Audio.
USB 1.0
Next is the USB version 2.0, which was launched in April 2000 and the use of standard USB-IF (Implementers Forum) at the end of 2001. Some large companies join to develop USB 2.0, USB 2.0 and eventually it has the capability of data transfer rate of up to 480 Mbit / s, far compared with USB 1.0 which only has a data transfer rate of 12 Mbit / s. Some large companies that developed the USB 2.0 is Hewlett-Packard, Intel, Lucent (now LSI Corporation), Microsoft, NEC, and Philips.USB 2.0
Even the more advanced-technology, USB 3.0 was introduced in September 2007. In version 3.0, data transfer rate could rise sharply up to 10 times more than previous versions. Then, USB 3.0 is referred to as SuperSpeed USB. Uniquely, a USB 3.0 also supports earlier versions, with the sense that the connector can also be used for USB 2.0, which is known by the name of backward compability.
USB 3.0Until now, the USB version 3.0 is the most advanced USB technology.

Webcam Technology

Webcams (short for web cameras) is the designation for real-time camera (meaning the state at this very moment) in which the pictures can be accessed or viewed via the World Wide Web, instant messaging program, or a video call applications. The term "webcam" also refers to the type of camera used for the purposes of ini.Webcam usually resolution of 352 × 288/640 × 480 pixels. But there is a quality to 1 Megapiksel.Sekarang almost all digital cameras and mobile phones can be used as a web camera (webcam). Many of the benefits of using a webcam which of them we can direct face-to face we speak in different computers, and we also know bissa our speaker activity on the computer at that moment. PC video camera or Web camera functions like video recording device (camcorder) which is connected to your PC. Camera was merakam video and images you and allow you to speak in the video or merakam and edit video clips via e-mail application and Web.Di addition, you can also see where a web service that uses video applications such as CU-SeeMe, where you allowed to speak and see the faces of the other users in the use of this web cam application services.
With this web camera, you can create its own digital video clips and meet with users around the dunia.Sebenarnya, web cam function is more similar to the message immediately or face to face directly. You only need to add digital video into Internet connections are available to see your friends in other locations. That's why the Internet connection is required for meetings with video meetings Web.Webcam usually with two kinds of PCI or USB devices. PCI is a standard tool that is widely used to connect the equipment and the additional card to the computer system. USB (Universal Serial Bus) is a popular tool that complements almost any new computer system (similar to the type of desktop or notebook). The model of your choice also depends on computer systems that support USB devices. When the model by using a PCI video camera may be more difficult to install, karana involve installation of a video recorder card (video capture card) or capture video. However, the tool offers more speed when face to face with a camera USB.Secara generally, the price of video cameras and the type of PCI card recorder is more expensive, but if you want a clearer picture quality, then you need a camera type of PCI. USB type also has its own advantages such as easy to use. Connecting and installing cameras of this type just as easy as plugging the cord.Positive Impact of Web CamAdvantages and usefulness of Web Cam very important function for entrepreneurs. With interactive Web Cam with a businessman who has a multinational company can conduct a meeting in the various branches of his company in many countries, he can control the development of his company to continue to monitor and interact directly with the head branchUses Web Cam not only for business purposes but can also be used for security cameras used in the homes, apartments, companies, etc..Interactive with our friends of different cities and even countries to give up longing, face to face with the brothers and their parents and speak as if technology is making the world a little.
Negative Impact
Negative impacts that may arise from the use of Web Cam like the case of an American boy named Justin Berry, this case tells the story of a child who is very fond with web cam chat she often meet with various people, one day a phedophilia samapai asks him to took off her clothes in front of the camera with the lure gets $ 50, then he does not realize that it is sexual harassment.It can be concluded that the dangers posed computer that has Internet network berfasilitaskan web cam is the range used by the children to do activities that should not have, porn sites, web Girls are particularly vulnerable opened by children without parental supervisionTo make students lazy to learn because fall asleep with a web cam service, lack of socialization with friends are highly vulnerable to future childrenNumber of fraud committed by the Web protistusi Girls, like asking to meet and make an appointment to meet and do things that are not obscene, but usually he requested a transfer fee in advance with the target via a web cam to woo, to perform various seductive poses in front of a camera trap men to want to do apaun to meet and date with Web Girls.
A simple web camera consists of a standard lens, mounted on a circuit board to capture the image signal; casing (cover), including the chassis front and side casings to cover the standard lens and has a hole in the casing front lens that allows you to insert images; support cables, made of flexible material, one end connected to the circuit board and another end has a connector, this cable is controlled to adjust the height, direction and angle of view of a web camera. A web camera is usually equipped with the software, this software takes the images from digital cameras continuously or in a certain time interval and broadcast it via an internet connection. There are several methods of broadcasting, the most common method is a software to convert images into a JPEG file and uploading to web server using File Transfer Protocol (FTP).
Frame rate indicates the number of images of a software to capture and transfer in one second. For streaming video, it takes a minimum of 15 frames per second (fps) or ideally 30 fps. To obtain a high frame rate, it takes a high-speed Internet connection. A web camera is not necessarily connected to the computer, there are web cameras that have the webcam software and bulit-in web server, so all you need is an internet connection. Web cameras like this are called "network cameras". We can also avoid the use of wires using radio link, an Ethernet connection or WiFi.

Apple vs. Microsoft: Microsoft As Apple Slide's Largest IT Company

Microsoft's dominance as the most valuable technology company in the world has ended. Apple managed to menumbangkannya and now holds the title as the biggest tech giant.
At the close of stock trading on Wall Street yesterday, Apple's enterprise value reached U.S. $ 223 billion, while Microsoft's U.S. $ 219 billion. This is the first time that Apple managed to surpass Microsoft. Such information is quoted from the Wall Street Journal on Thursday (27/05/2010).
It's just in terms of revenue, Apple is still under Microsoft, by comparison to U.S. $ 42.9 billion for Apple and Microsoft gets U.S. $ 58.4 billion. While in the last fiscal year, Apple's net income of U.S. $ 5.7 billion, while Microsoft's U.S. $ 14.6 billion.
This event is like a symbol that shows differences in the direction of the two big companies to be able to lead. With the iPhone and iPod, Apple showed growth has skyrocketed. In the second quarter of 2010, profits increased 49 percent from last year.
While Microsoft is known as the software giant has dominated the realm of computers for nearly two decades. But then, consumers were enchanted by the Apple handheld device. Although Apple has tried to compete with menyebur into the arena of mobile devices and tablet computers, Microsoft products are in fact still overshadowed.

4th generation iPod Touch 4G central: See the new iPod Touch 4

iPod Touch 4 with Retina display and double camera announced - Breaking News

With the live Apple Music event just concluding we are happy to announce that Apple has officially launched the brand new iPod Touch 4 with Retina display,  front facing facetime camera, and a rear HD video camera as well.
The new 4th generation iPod Touch 4
It looks like most of what has been rumoured has been delivered today, with the important parts being Retina display and camera. The new 4th generation iPod Touch 4 has also received the new Apple A4 chipset for improved processing, and it has all been packaged into an even slimmer designed iPod Touch.
With the new iOS 4.1 for the new iPod Touch 4 also comes Gamecenter for social gaming between friends + many other new features.
We will be back with a full iPod Touch 4 review later, and updated best price iPod Touch 4 tables when retailers start announcing their prices.
Older rumours around the iPod Touch 4 follows below.
Retina display and leaked images of facetime camera
With only weeks expected until Apple announces the new 2010/11 range of Apple iPods, new leaked images of what could be the iPod Touch 4 with facetime camera has found their way into the market. Components in the images are clearly marked with Apple, but so far no official word on if this is actually images of  the 4th generation iPod Touch.
Further information also suggest that the new iPod Touch 4 will receive the same Retina display as the iPhone 4.
facetime, camera, and 3G data plans
Following some John Lewis based “leaks” the next generation iPod Touch 4 will get many of the new features found in the iPhone 4, including the camera and facetime functionality. However many other online sources think this might be too good to be true, and that we are more likely to see a camera similiar to iPhone 3GS, and if we are lucky facetime and 3G version of the iPod Touch 4.
Release of iOS4 and iPhone 4
With the release of the iPhone 4 and the announcement of the iOS 4, which by the way will be a free upgrade for all 2nd and 3rd generation iPod Touch owners, there are some positive possibilities to take out of it.
The iPhone 4 has received the A4 chipset from Apple, as well as an improved battery and of course the 5 megapixel camera, including a forward facing one for video calling. Given what Apple has been able fit into a smaller framed iPhone 4, there should be nothing stopping Apple from adding some of these features to the 4th generation iPod Touch 4 as well, unless they are not interested in breathing new life into the iPod Touch that is.
Firmware 3.1.3 reveals iPod Touch G4 code name N80
In the aftermath of the Apple iPad launch and the upgraded iPhone 3.2 SDK and 3.1.3 firmware, Engadget has been digging deep into the code of the firmware upgrade revealing references to two new models, the N89 and the N80. They have strong sources indicating that the N89 is the code name of the coming iPhone 4G, whilst the code name N80 is in reference to the 4th generation iPod Touch G4.
Older news and rumors around the 4th generation iPod Touch 4G follows below.
The iPod Touch vs Apple iPad
In many ways the Apple iPad is like an oversized iPod Touch, with some added features, features that we might be getting with the next iPod Touch as well. In the aftermath of the iPad launch it also became known that Apple has changed their mind over VOiP apps over 3G network, revising their Program License Agreement together with the newly released Software Development Kit, opening up for apps to utilize the cellular networks. As we now know, the Apple iPad will feature a micro SIM card tray, so the question has to be raised; will the 4th generation iPod Touch 4G feature a SIM card tray as well?
The way we see it there is no doubt that the Apple iPad will have an impact on the sales of the iPod Touch in the future. Given its price point, closer to the iPod Touch, its larger screen, and the addition of iBook, there is going to be some cannibalization between these two Apple products. However we believe that the iPod Touch will still have a strong future if Apple delivers the same functionality in the 4th generation iPod Touch.
Give the iPod Touch an improved processor, SIM card tray with 3G data connectivity and unlocked data plans,  and a camera, and Apple might just get the portable gaming device that will complement the Apple iPad. That combination will however raise the question around the balance between the iPod Touch and the Apple iPad on one hand, and the iPhone -  it is a fine balance Apple is walking to ensure that all products deliver the optimum for the bottomline and value for the shareholders.
Camera and flash
Ever since Apple announced the 3rd generation iPod Touch without camera back in September 2009 we have all been scratching our heads wondering what happened and why. With the likely issue being problems with a camera sensor that has now been fixed, we are again looking at camera for the iPod Touch, and perhaps the 4th generation iPod Touch G4 will come earlier than September 2010.
Some have speculated in the iPod Touch getting an iPod Nano type video camera as early as spring this year, but we think that would just lead to more dissappointment from the hords of iPod Touch fans out there. With the latest rumors that Apple is looking to purchase LED flash camera components for the iPhone 4G,  expected summer this year, there should be hope that the same components can also find their way into the iPod Touch 4G 4th generation, with perhaps a slightly earlier release date than the normal September for iPod renewals.
Although this is speculations based on rumors around the iPhone 4G, we could be looking at a 4th generation iPod Touch G4 featuring a 5 megapixel camera with LED flash, something that would be a significant boost over the current model, especially of combined with other expected features.
Some of the other features one could expect from the 4th generation iPod Touch G4 would be:
  • Improved capacity to 128GB with the new NAND flash memory chips
  • Improved processing speeds and network capabilities
  • Multitasking with background processing of applications
  • Improved battery life
Some of the above are more likely than others as Apple has always improved the iPod Touch once a year with improved components. With gaming use and the increase in apps that are getting more and more resource heavy, improved battery life is turning out to be a popular request, and a very welcomed improvement.
We will be back with more information as more the sources become more reliable about the 4th generation iPod Touch G4.

History of Toshiba Corporation

Toshiba was founded by the merging of two companies in 1939.
One, Tanaka Seisakusho (Tanaka Engineering Works), was Japan's first manufacturer of telegraph equipment and was established by Hisashige Tanaka in 1875. In 1904, its name was changed to Shibaura Seisakusho (Shibaura Engineering Works). Through the first part of the 20th century Shibaura Engineering Works became a major manufacturer of heavy electrical machinery as Japan modernized during the Meiji Era and became a world industrial power.

The second company, Hakunetsusha, was established in 1890 and was Japan's first producer of incandescent electric lamps. It diversified into the manufacture of other consumer products and in 1899 was renamed Tokyo Denki (Tokyo Electric).
The merger in 1939 of Shibaura Seisakusho and Tokyo Denki created a new company called Tokyo Shibaura Denki (Tokyo Shibaura Electric) (浦電気). It was soon nicknamed Toshiba, but it was not until 1978 that the company was officially renamed Toshiba Corporation.
The group expanded strongly, both by internal growth and by acquisitions, buying heavy engineering and primary industry firms in the 1940s and 1950s and then spinning off subsidiaries in the 1970s and beyond. Groups created include Toshiba EMI (1960), Toshiba International Corporation (1970's) Toshiba Electrical Equipment (1974), Toshiba Chemical (1974), Toshiba Lighting and Technology (1989), Toshiba America Information Systems (1989) and Toshiba Carrier Corporation (1999).
Toshiba is responsible for a number of Japanese firsts, including radar (1942), the TAC digital computer (1954), transistor television and microwave oven (1959), color video phone (1971), Japanese word processor (1978), MRI system (1982), laptop personal computer (1986), NAND EEPROM (1991), DVD (1995), the Libretto sub-notebook personal computer (1996) and HD DVD (2005).
In 1977, Toshiba merged with the Brazilian company Semp (Sociedade Eletromercantil Paulista), forming Semp Toshiba.
In 1987, Toshiba Machine, a subsidiary of Toshiba, was accused of illegally selling CNC milling machines used to produce very quiet submarine propellers to the Soviet Union in violation of the CoCom agreement, an international embargo on certain countries to COMECON countries. The Toshiba-Kongsberg scandal involved a subsidiary of Toshiba and the Norwegian company Kongsberg Vaapenfabrikk. The incident strained relations between the United States and Japan, and resulted in the arrest and prosecution of two senior executives, as well as the imposition of sanctions on the company by both countries. The US had always relied on the fact that the Soviets had noisy boats, so technology that would make the USSR's submarines harder to detect created a significant threat to America's security. Senator John Heinz of Pennsylvania said "What Toshiba and Kongsberg did was ransom the security of the United States for $517 million."
In 2001, Toshiba signed a contract with Orion Electric, one of the world's largest OEM consumer video electronic makers and suppliers, to manufacture and supply finished consumer TV and video products for Toshiba to meet the increasing demand for the North American market. The contract ended in 2008, ending 7 years of OEM production with Orion.
In December 2004, Toshiba quietly announced it would discontinue manufacturing traditional in-house cathode ray tube (CRT) televisions. In 2006, Toshiba terminated production of in-house plasma TVs. Toshiba quickly switched to Orion as the supplier and maker of Toshiba-branded CRT-based TVs and plasma TVs until 2007. To ensure its future competitiveness in the flat-panel digital television and display market, Toshiba has made a considerable investment in a new kind of display technology called SED.
Before World War II, Toshiba was a member of the Mitsui Group zaibatsu (family-controlled vertical monopoly). Today Toshiba is a member of the Mitsui keiretsu (a set of companies with interlocking business relationships and shareholdings), and still has preferential arrangements with Mitsui Bank and the other members of the keiretsu. Membership in a keiretsu has traditionally meant loyalty, both corporate and private, to other members of the keiretsu or allied keiretsu. This loyalty can extend as far as the beer the employees consume, which in Toshiba's case is Asahi.
