The world’s first printer was created in the 1800’s, mechanically driven apparatus. This system used a series of metal rods with characters printed on them and stuck a roll of paper against the rods to print the characters. The first commercial printer commonly used mechanisms from electric typewriters, which worked in a similar manner. The demands for increased speed forwarded to the improvement of new systems genuinely for computer use. Among the systems widely used through the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix system that could mix text and graphics but reveal relatively low quality output. The plotter was used for those users that need the high quality line are like blueprints. The beginning of the low cost laser printer in 1984 with the first HP laser jet, set of a evolution in printing known as desktop publishing. Laser printer using post script mixed text and graphics, like dot matrix printers, however it was a high quality formerly available only from commercial typesetting system. By 1990, the most original printing task like filers and brochures were now made on personal computers and then laser printed; expensive offset printing systems were being regarded as scrap. The HP Deskjet of 1988 offered the same advantages as laser printer in relation to of flexibility, but generated somewhat lower quality output from much less mechanisms. The quick update of internet email through the 1990s and into the 20000s has largely taken overs the need for printing as means of moving documents, and a wide variety of reliable storage systems. Traditional printer are being function more for special purposes, like printing photographs or artwork, and are no longer a must have peripheral.
Computer monitors is a fundamental component of the modern world. Early in the development of computer, a display consisted of nothing but a flashing lights that indicated different function, for people who thoroughly understand computer systems, this is imperative information about what part of the computer’s memory the user is accessing or what function the computer is performing. Plasma monitors were also developed in the 1960 as where the teletypes. Another display technology developed during the 1960s was the liquid crystal display. These display were energy efficient, thin and inexpensive, but they were hard to read without either back lighting or direct illumination. As time progressed, so did the number of colours and the defined displays. Until the 1987, there were variety of different monitor schemes, including VGA. In 1987. The VGA monitor scheme won out, and since then nearly every monitor has been produced according to its standards. The monitor of today are primarily LCD based. In the 1990s, LCD screen became more easily coloured, cost efficient and faster to refresh. These features made LCDs a common component in laptop computer displays, and eventually LCD made the step into TV and desktop applications LCD screens have outsold CRT displays, and the numbers have increased dramatically every year since. Current work on monitor consist of 3D support. While 3D screen still require the use of specialized glasses, work is being done on stereoscopic and glasses free alternative.
The very first idea of a smartphone is said to have been envisioned back in the mid-1970s, but the idea didn’t come into production until almost 20 years later when IBMs Simon’s personal communicator first showed its face in 1992. In the early 2000s, Symbian, BlackBerry OS, Palm OS, and Windows Mobile became increasingly popular. With functions such as email, fax, Web browsing, and other enterprise-centric features, so did form factors that assisted to such use cases. Between 2000 and 2006, cell phone manufacturers explored a lot of different form factors to distinguish on the new mobile functionality. Sliding and flipping
