  What is Mobile Computing ? Definition :   Mobile Computing System mean Wireless communication  and its applications  are generic technology that refers to numerous devices that are supportable to access transmitted data like voice, video, and text any time and any where over the wireless network infrastructure. This includes mobile communication, mobile hardware, and mobile software and this react as human-computer interaction. Cause of these has improved the quality of our lives. History and Evolution of Mobile Computing In 1894, Marconi done experiment along with Hertzian rays and identify the waves over very long distance. Then developed the first wireless telegraph company. 1980 –  Developed first consumer Laptop. 1981 –  Developed portable Computer by Epson. 1984 –  First touch screen laptop was developed. 1990 –  New portable laptop released by Apple with 640*640 display screen. 1992 –  Released standard Windows 3.1.1 Operating System...

  What is Laser Printer ? Definition :   Laser printer  uses the laser and electrical charge model beyond of the traditional printing like as ink onto the paper. Laser printer resolutions is 600 dpi (dots per inch); so it helps to provide neatness and better quality result. This printer  acts as photocopier  machine  that uses laser light and toner to print a document. In this printer, selenium coated drum is using that allows to print document with using of electrical charges. This printer provides print with the combination of electrical charges and toner, and after completing the printing the extra toner and electrical charges are discard from page. First laser printer designed by IBM, 1975 along with its  mainframe   computers. HP Company revolutionized laser-printing technology in 1984, and then introduced first LaserJet, fast, and reliable printer for using with personal computer. Types of Laser Printer There are  different types of las...

  What is Analog Computer ? Definition :  Analog computer is special  type of computer , where to use data in continuously form, not discrete, and changeable continues stream of data is known as “Analog Data”. These computers can store analog data in the continuous physical quantities likes as electrical potential, fluid pressure, or mechanical motion, and finally it produces the result with using of measures. Analog computers are using in such areas, where to need data to be measure directly without transforming into numbers. Analog computer uses the programs for transforming of problematic equations into analog circuit.  Let’s Get Started!! Types of Analog Computers Slide Rules Differential Analysers Castle Clock Electronic Analog Computers Mechanical Analog Computers Pneumatic Analog Computer Hydraulic Analog Computer Slide Rules Slide Rule is very simplest types of analog computer, and this computer helps to produce approximate result for simple mathematical oper...
