There are many features on this device such as windows 7 has carried over the use of many of the applications as windows xp without the hassle of waiting for the system to adjust. Another feature is that it runs on lower hardware requirements this adds to the previous feature but in a different way by making it usable on netbooks effectively making it a good replacement for prior operating systems on the device. An immensely helpful feature is the further organization on the task bar. The icons and applications have been grouped together for greater accessibility and multiple windows of the same application open and stacked. There are also some pretty simple features of the windows7 OS such as aero shaker. This allows you to focus on one window by grabbing the address bar at the top and shaking it with your mouse this will minimize all the other windows you have on your screen. Stacking is also a new simple feature that allows you to drag a window to the side of the screen where it will automatically stay and fill half the screen allowing for users to view multiple windows in a much more simple manner. There are many other features provided in the windows7 operating system that may be found useful go out and find them and enjoy it for yourself.

...For this lab I will be using my home laptop. When purchasing this computer I thought it was a very nice computer. However after doing this lab and looking into what runs this computer I am beginning to think I may have overpaid. That just goes to show that you cannot trust salesman! This HP laptop was purchased running Windows 7 as the operating system.. However roughly two months after purchase I received a notification that I could receive a Windows 10 download for free. So as of now the computer is running Windows 10 for the operating system. One of the first things I’ve noticed with Windows 10 is the start menu. With the improved start menu you can pin app tiles right on the start menu, including live tiles! I just began realizing how nice of a feature this is. Windows 10 also has an action center which is carried over from the Windows phone. With the action center you configure the options on how you want notifications from apps as well as what functions you want to be able to have access to quick toggle on and off! Windows 10 also introduced Cortana, which is a digital personal assistant. Cortana is a search engine and so much more. With Cortana I can send emails using my voice with no extra program needed for voice recognition. It can notify me on when to leave home for work or meetings/calendar events. I think one of the features I really like is that I can launch apps with voice recognition. By just saying “hey Cortana, launch Microsoft word”. Another feature Microsoft...

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...

...Electronics rely heavily on electronic switching and amplification to generate and capture the various signals which allow them to operate. A controllable valve that allows a small signal to control a much larger signal does this, and could be related to a controllable valve used in the control of water flow. This was once done by a device known as vacuum tube but was later brought down to a much lower production scale for a variety of industrial, economical and business related reasons. Bell Laboratories, the research arm of telecommunications company American Telephone and Telegraph’s (AT&T) director Mervin Kelly put together the first team of researchers and scientists placed on the task of research and development of a solid state-semiconductor later called a transistor that would supersede vacuum tubes and provide numerous advantages. The success of this development would prove to change the computing, electronics and telecommunications systems altogether. Up until the invention of the transistor a vacuum tube was used in the control, amplification and generation of electrical signals. Vacuum tubes are tubes usually made from glass and designed in an airtight manner as to keep the flow of “cathode rays” from external disturbance as they pass from each terminal and laid the foundation for numerous technical innovations, such as the light bulb discovered by Thomas Edison (fig. 1). Joseph John Thomson further made a vacuum tube and placed a third terminal to attain a grasp...
