Who Invented the Mouse?

Who Invented the Mouse?

The origin and history of the mouse began in 1964. That was the year Douglas Engelbart invented the first mouse prototype. He actually started working on the device the year before. He got the patent in 1970. The First Mouse In 1964, Engelbart showed the mouse to his colleagues at STI (Stanford Research Institute) and how the device was used. He utilized it on a computer with a graphical user interface (GUI). His prototype mouse had a wooden shell. It also came with a couple of wheels which helped it move around. When Engelbart applied for the patent, he called it the “X Y position indicator for a display system”. But the history of the mouse shows that the name was used early on. According to Engelbart he called it the mouse because the shape and tail made it look like one. Note: the GUI and windows that Engelbart used were also his inventions. But he couldn’t patent them because computer program patents weren’t available yet. Innovations in Mouse Design In 1972 Bill English (who helped Engelbart make the mouse) created the ball mouse. English was working at Xerox at the time and his invention became part of the Xerox Alto computer. The ball mouse was easier to use than the wheeled mouse. Unlike the latter, the device could be moved in any direction with ease. In the history of the mouse, this innovation is considered as one of the major ones. Over time, the ball mouse became the most popular version of the device. By the 1980s and the 1990s, the ball had become a standard feature in almost all mice sold. Based on English’s design, other types of ball mice emerged. Among the innovators and inventors were...
Who Invented Email?

Who Invented Email?

The history of email began with Ray Tomlinson in 1971. The program was created while he was working for the US government, specifically ARPANET (the future Internet). Tomlinson’s Work Tomlinson was working for the United States Defense Department in 1968. He was a computer engineer at the time. He started by developing an application called SNDMSG. Its purpose was to let ARPANET users relay messages. Originally, SNDMSG was local. That is, the messages could be sent only to users of that same computer. Tomlinson used the CYPNET (a transfer protocol) on the SNDMSG application. This allowed SNDMSG to send and receive email to any computer within the ARPANET network. This was how the history of email began. The First Email Message Tomlinson utilized the @ symbol for a simple reason: it would enable him to know which individual was at the system. Back them, the @ was inserted between the computer host and the user name. The first email Tomlinson sent was QWERTYUIOP. Early Use of Email Following Tomlinson’s invention, the service started to be used in the ARPANET. It was connected to the FTP (File Transfer Protocol). The FTP would eventually be replaced by the SMTP (Simple Mail Transfer Protocol). FTP is still sometimes used today when downloading files off the World Wide Web. However it is important to note that email is much older than the Internet. Email was being used at ARPANET in the 1970s, long before the Net came into being. Other Email Prototypes The history of email shows that MIT had already demonstrated its potential back in 1961 with Compatible Time Sharing System (CTSS). This technology permitted users to gather and share files online. The other prototypes permitted communication on the mainframe. However it...
Who Invented the MP3 Format?

Who Invented the MP3 Format?...

The mp3 format was invented by the MPEG Group in 1991. The history of the mp3 format indicates several people worked on the project but the accredited inventors were Ernst Eberlein, Thomas Sporer, Karhl Heinz Brandenburg, Bern Grill and Bernd Kurten. Development Mp3 was the offshoot of OCF and PXFM. Those who worked on the project were mainly focused on how people were able to hear music. Through the course of their work, the Fraunhofer Society (which became part of the MPEG group) started looking for ways for music to be compressed and yet maintain its high quality. After working on it for several yeas, the standards were implemented in 1991. Further refinements would follow and it was integrated with MPEG 2 which came out in 1994. Release to the Public A study of the history of the mp3 format will reveal the Fraunhofer Society produced the encoder on July 7, 1994. A few months after its release, an mp3 player called Winplay 3 was released as well. Unlike other music formats, Mp3 offered a lot of advantages. The first was its small size. Using the 128 bit compression, a 5 minute song only came in at about 5 MB. This was a huge improvement over the WAV formats whose size was ten times that. In addition, the quality was very high, almost CD like. This became possible due to limitations in hearing. Mp3 removed the bits in the sound file that people wouldn’t be able to hear. By taking out these extraneous pieces, the size was reduced without sacrificing the sound quality. Popularity and Widespread Use Through the 1990s, the history of the mp3 format shows the tremendous impact it made on the Net. The release of Winamp...
Who Invented the Internet?

Who Invented the Internet?...

The Internet was not created by a single individual. If you assess the history of the Internet, it will reveal that it was the product of different ideas and concepts that merged together. Origin of the Internet The basic ideas for the Internet came in 1957. The US Defense Department created the ARPA (Advanced Research Projects Agency). Its purpose was to produce technologies that the military could use. In the 1960s ARPA and MIT (Massachusetts institute of technology) corroborated to share information and technology. They would do this by joining networks using phones. In 1966, Larry Roberts (from the MIT) introduced the ARPANET, which consisted of computers linked over long distances. The history of the Internet was also affected by packet switching, a technology that allowed for faster and cost effective data transmissions. In 1969, universities were allowed to be a part of the network nodes. UCLA and Standard were among the early ones. By 1971, several more universities were included. By 1973, ARPANET had also established a node in London, England. The 1970s Several milestones were attained in the 1970s. TCP (Transmission Control Program) was developed and made data transfer easier. Unix was also developed in 1976 and the same year email was used for the first time by the Queen of England. The history of the Internet in the 70s was also marked by the birth of USENET. This would be the model upon which all discussion groups and forums would be modeled. The 1980s and 1990s The development of the TCP/IP (Transmission Protocol and Internet Protocol) in 1982 is one of the earliest references to the word Internet itself. In 1985 symbolics.com became the initial domain name to be registered. It was in 1988 that the...
Who Invented Google?

Who Invented Google?

Google is one of the most popular and widely used search engines today. The company that developed the website is earning big profits from online mapping, e-mail messaging, social networking, video sharing, Internet search as well as office productivity. To help people from the different parts of the world have access to world’s information, Google Inc. also created a reliable mobile operating system and an efficient open source web browser. To know more about the success attained by the company, it is best to identify the people who contributed to the invention of the famous search engine. History of Google Who invented Google? Sergey Brin and Larry Page invented Google as a special project when they were students of Ph. D. at Stanford University in January 1996. The primary function of the search engine was to develop an efficient digital library for the students of the university. The project was funded and supported by the Graduate Fellowship of the National Science Foundation. To create the search engine, Page and Brin developed a very useful computer language known as the PageRank algorithm. The original domain name of the program created by the inventors is google.stanford.edu. It was only changed to google.com when they register the website on September 15, 1997. The inventors of the search engine established the company Google Inc. on September 4, 1998. After a year, the company relocated its offices to 165 University Avenue at Palo Alto. At first, the company only leased several buildings for the business operations. In 2006, the company purchased the properties for $319 million. Additional Information and Other Important Details To enhance the revenues of the company, Google Inc. started offering different advertisements related to search keywords in 2000. To keep the...
Who Invented Video Games?

Who Invented Video Games?...

No single individual can be credited with creating the first video game. But as this brief history of video games will show, several people played a prominent role in its growth and expansion. The Earliest Video Games The records show that in 1952, A.S. Douglas developed a graphical computer game. The game was Tic Tac Toe and it was created on the EDSAC vacuum tube computer. However it isn’t generally considered to be a video game. The first real video game is said to be William Higinbotham’s Tennis for Two. This game came out in 1958. The next innovation came in 1962 when Steve Russell came out with Spacewar! The game was played on a MIT PDP-1 mainframe computer. The history of video games would change in 1967 when Ralph Baer created a game called Chase. It was the first game to be played on a TV screen. The 1970s Arcade Games Several important developments took place in the 1970s. Nolan Bushnell and his associate Ted Dabney came out with Computer Space, and the video arcade was born. In 1972 the game Pong came out (Pong is often erroneously referred to as the first video game). Later that year Bushnell and Dabney would team up again and form Atari Computers. It was also in 1972 a home video game console became available. It was produced by Magnavox. Called the Odyssey, it came with a dozen games. Four years later, the Fairchild Video Entrainment System appeared. A study of the history of video games will show that a lot of the classic games came out during the 1970s. Following the success of Atari, Space Invaders came out in 1978, and was also well received. In 1979, colors began to be...
