Facebook.
Facebook is a social networking service and website launched in February 2004, operated and privately owned by Facebook, Inc. As of January 2011, Facebook has more than 600 million active users. Users may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Facebook users must register before using the site. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics. The name of the service stems from the colloquial name for the book given to students at the start of the academic year by university administrations in the United States to help students get to know each other better. Facebook allows any users who declare themselves to be at least 13 years old to become registered users of the website.
Facebook was founded by Mark Zuckerberg with his college roommates and fellow computer science students Eduardo Saverin, Dustin Moskovitz and Chris Hughes. The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It gradually added support for students at various other universities before opening to high school students, and, finally, to anyone aged 13 and over, but based on ConsumersReports.org on May 2011, there are 7.5 million children under 13 with accounts, violating the site's terms.
A January 2009 Compete.com study ranked Facebook as the most used social networking service by worldwide monthly active users, followed by MySpace. Entertainment Weekly included the site on its end-of-the-decade "best-of" list, saying, "How on earth did we stalk our exes, remember our co-workers' birthdays, bug our friends, and play a rousing game of Scrabulous before Facebook?"Quantcast estimates Facebook has 138.9 million monthly unique U.S. visitors in May 2011.According to Social Media Today, in April 2010 an estimated 41.6% of the U.S. population had a Facebook account.

History
Main articles: History of Facebook and Timeline of Facebook
Mark Zuckerberg wrote Facemash, the predecessor to Facebook, on October 28, 2003, while attending Harvard as a sophomore. According to The Harvard Crimson, the site was comparable to Hot or Not, and "used photos compiled from the online facebooks of nine houses, placing two next to each other at a time and asking users to choose the 'hotter' person"
To accomplish this, Zuckerberg hacked into the protected areas of Harvard's computer network and copied the houses' private dormitory ID images. Harvard at that time did not have a student "facebook" (a directory with photos and basic information). Facemash attracted 450 visitors and 22,000 photo-views in its first four hours online.
The site was quickly forwarded to several campus group list-servers, but was shut down a few days later by the Harvard administration. Zuckerberg was charged by the administration with breach of security, violating copyrights, and violating individual privacy, and faced expulsion. Ultimately, however, the charges were dropped. Zuckerberg expanded on this initial project that semester by creating a social study tool ahead of an art history final, by uploading 500 Augustan images to a website, with one image per page along with a comment section.He opened the site up to his classmates, and people started sharing their notes.
The following semester, Zuckerberg began writing code for a new website in January 2004. He was inspired, he said, by an editorial in The Harvard Crimson about the Facemash incident. On February 4, 2004, Zuckerberg launched "Thefacebook", originally located at thefacebook.com.
Six days after the site launched, three Harvard seniors, Cameron Winklevoss, Tyler Winklevoss, and Divya Narendra, accused Zuckerberg of intentionally misleading them into believing he would help them build a social network called HarvardConnection.com, while he was instead using their ideas to build a competing product. The three complained to the Harvard Crimson, and the newspaper began an investigation. The three later filed a lawsuit against Zuckerberg, subsequently settling.
Membership was initially restricted to students of Harvard College, and within the first month, more than half the undergraduate population at Harvard was registered on the service. Eduardo Saverin (business aspects), Dustin Moskovitz (programmer), Andrew McCollum (graphic artist), and Chris Hughes soon joined Zuckerberg to help promote the website. In March 2004, Facebook expanded to Stanford, Columbia, and Yale. It soon opened to the other Ivy League schools, Boston University, New York University, MIT, and gradually most universities in Canada and the United States.
Facebook incorporated in the summer of 2004, and the entrepreneur Sean Parker, who had been informally advising Zuckerberg, became the company's president. In June 2004, Facebook moved its base of operations to Palo Alto, California. It received its first investment later that month from PayPal co-founder Peter Thiel. The company dropped The from its name after purchasing the domain name facebook.com in 2005 for $200,000.
Facebook launched a high-school version in September 2005, which Zuckerberg called the next logical step.At that time, high-school networks required an invitation to join. Facebook later expanded membership eligibility to employees of several companies, including Apple Inc. and Microsoft. Facebook was then opened on September 26, 2006, to everyone of age 13 and older with a valid email address.
On October 24, 2007, Microsoft announced that it had purchased a 1.6% share of Facebook for $240 million, giving Facebook a total implied value of around $15 billion. Microsoft's purchase included rights to place international ads on Facebook. In October 2008, Facebook announced that it would set up its international headquarters in Dublin, Ireland. In September 2009, Facebook said that it had turned cash-flow positive for the first time. In November 2010, based on SecondMarket Inc., an exchange for shares of privately held companies, Facebook's value was $41 billion (slightly surpassing eBay's) and it became the third largest US web company after Google and Amazon. Facebook has been identified as a possible candidate for an IPO by 2013.
Traffic to Facebook increased steadily after 2009. More people visited Facebook than Google for the week ending March 13, 2010.
In March 2011 it was reported that Facebook removes approximately 20,000 profiles from the site every day for various infractions, including spam, inappropriate content and underage use, as part of its efforts to boost cyber security.
In early 2011, Facebook announced plans to move to its new headquarters, the former Sun Microsystems campus in Menlo Park, California.

History And Development of Digital Cameras

Digital camera technology is directly related to and evolved from the same technology as when used to record images on television. In 1951, for the first time a video tape recorder (VTR) to take pictures of the television camera, then convert that information into an electrical impulse (digital) and store such information into the magnetic tape.

Bing Crosby laboratories (the research team, funded by an engineer named Vrosby and led by John Mullin) makes an early version of the VTR. In 1956, VTR technology was perfected (VR1000 made ​​by Charles P. Ginsburg and the Ampex Corporation) and commonly used by the television industry
Between television / video cameras and digital cameras that use CCD (Charged Couple Device) to adjust color and light intensity. At the same time the digital camera era has started with very rapidly.

In 1981, Sony introduced their first commercial electronic camera called the Mavica. Images are recorded onto a mini disc and then put into a video reader that is connected to a monitor or color television. Although it can not be said Mavica digital camera, it is actually a modification of a video camera that takes pictures spontaneously.

Since the mid-1970s, Kodak has a few discoveries about solid-state/kejernihan for image sensors that convert light into digital images for use on a professional level and household consumers.

In 1886, Kodak scientists for the first time in the world introduces megapixel sensor, where the sensor is capable of recording 1.4 million pixels that could produce 5 × 7 inch digital photo print quality at the time. In 1987, Kodak released seven products for recording, storing, manipulating, electronic transmission, and print something like the image of an object.

In 1990, Kodak developed a photo CD system and proposed the first time all over the world to establish digital color standards in an environment of computers and computer peripherals.
In 1991, Kodak released the first time for professionals, a system in shooting yanitu Digital Camera System (DCS), which aims to photo journalism. The camera is a Nikon F-# which is equipped with 1.3 Megapixels sensors.

The first digital camera to the consumer level market that worked with a home computer via USB (Unit serial bus) is a QuickTake 100 camera Aplle (February 17, 1994), the Kodak DC40 camera (March 28, 1995), Casio qv-11 (with LCD monitor, the final 1995), and Sony Cyber​​-Shot Digital Still Camera (1996).

However, kodak entered the era with an aggressive marketing campaign to promote the DC40 and helped introduce the idea of ​​digital photography to the public.

Kinko's and Microsoft is working with Kodak Digital to create digital images using software in a variety of workplace and photo kiosks, where customers are allowed to produce photo CDs, digital images, and then can add to their computer documents. IBM works with Kodak membaut image exchange network-based Internet.

Hewlett-Packard (HP) is the first company in terms of making colors in their products are inkjet printers, so the complement staining system for printed pictures from a digital camera. So began the changes digital camera with a new shape. Digital cameras as conventional cameras, available models of Point-And-shot and single-lens reflex digital or Digital Single Lens Reflector (SLR).

Note Down
Point-and-Shoot Cameras are small cameras, cheap, and easy to use, because it contains only the camera lens and a built-in flash. To get a picture frame, the camera has a Liquid Crystal Display (LCD) viewfinder berbasi.

Advantages and disadvantages of model-And-Shoot poit is that the camera is designed for ease of use. Although this model still has limitations, namely the use of control over the camera. Some cameras have a mengatru focus and exposure automatically.

DSLR Camera is a camera with inverse model of the Point-And_shoot Camera. DSLR cameras have optical viewfinders, removable lens, external flash, and the ability to fikus and the ability to adjust exposure manually when needed.

This is a direct replacement of a camera that uses film negative model-based single-lens reflex, or Single Lens Reflex (SLR) which is used most people in ancient times. For this reason, digital SLR cameras tend to be more complicated and expensive than the camera model Point-And-Shoot.

Early-generation digital SLR models tend to be more expensive and larger than a camera that uses film negative. At present this is no longer the case, because the digital SLR cameras become cheaper, lighter and more compact in accordance with the times, even the latest generation can display the picture quality of High Definition
