- 2. In 1975 Bill Gates and Paul Allen started up a company called Microsoft in which they had a mission to put a computer in every home. In 1980 Steve Bahlmer joined the team and they were brought a project code from IBM called chess. The three of them then began development of an operating system (OS) that would manage the hardware and also allow the software to work with the computer hardware. The development of the Microsoft Disk Operating System (MS-DOS) was finally completed in 1981 and IBM shipped the first systems running the new OS (Microsoft, 2015). Even though MS-DOS was still difficult for many to use it still allowed for people to interact with computers in a whole new way and really started a revolution in personal computing. 1975-1981
- 3. Once the Military decommissioned the ARPANET, the public use of the internet was granted. When the World Wide Web became publically available it changed the way that humans interacted with their computers. Berners-Lee developed the first web browser software called fittingly and utilized a server called CERN to demonstrate the use of the internet which led to the launch (Bryant, 2011). Once the internet launched in 1991 their was a post made on a newsgroup page explaining how to download and operate within the internet for all of the new users. Though this release didn’t change everything about computing on the first day, it definitely made a massive difference. Users were able to share, download, and view content from anywhere they had a computer and internet connection. 1991
- 4. The first release of Google’s Android Operating System (OS) was in 2008 which changed the mobile market and the way that we interacted with our cellular devices by creating an interactive phone, computer, and camera all in a single small device we carried everywhere. Android released to consumers on the T- Mobile HTC G1. The device didn’t have anything spectacular when it came to hardware but it they created an open source operating system which started a revolution in the mobile market (Verge Staff, 2011). Android got a lot of things right when it came to their user interface, such as the notification window, the use of widgets, and the overall look and feel and they did this on their first release. Though some changes have occurred and their has been much improvement to existing features and added features to the OS, they did an excellent job when it came to the user experience. 2008
- 5. What/How - Personal computing changed the way we interacted with computers and are commonly referred to as PC’s. The PC is a hardware/software environment that works together to allow for complex tasks to be completed and programs to run. These computers use a number of ways to store data such as a DVDRW, CDRW, thumb drive, external hard drive, SD card, and the internal storage. CD and DVD roms are still used but not nearly like they used to be since personal computers and the way we store our data is rapidly changing, using smaller and thinner devices with larger storage capacities and the ability to install programs and share information quickly straight from the internet or by using a USB thumb drive there is less of a need for the CD and DVD. Where/When – The personal computer was a home use computer that would allow people to be able to use them not only at home but in the office, and also allow for people to use them for entertainment. The PC allowed for computing power to be used whenever the user wanted to and wherever they wanted to use it with the Laptop or Tablet PC. Who/Why – Anyone who wants to use a PC can and almost everyone does. It would be easier to answer the question if you asked who does not use a PC. There are several reasons to use a personal computer such as graphic design, web browsing, creating numerous types of documents, online shopping, watching videos, video games, and the list goes on and on.

- 6. What/How – Mobile computing devices have a wide variety of products associated with this category such as Laptops, Tablets, Smartphones, MP3 Players, Mobile GPS navigation, and several other devices. The tablet computer incorporates a touchscreen for its main I/O interface and can have a keyboard/mouse added through their USB ports allowing for more functionality. Laptops come with keyboards attached with an embedded touch mouse and have a wide range of sizes. These devices are portable because they use batteries to power their hardware allowing for multiple on the go uses. Where/When – Like the name says, they are Mobile. This means that people can take these devices with them and conduct computer function anywhere they want and at anytime. With this functionality you can take the device anywhere, and they can use location-based mobile services (LMS) allowing for a wide variety or other services such as location based ads, GPS navigation built-in to the device, and several other services that are based on their mobility. Who/Why – Just like personal computing its easier to ask who doesn’t use a mobile computing device, they have become part of most peoples daily activities and are carried in peoples pockets. Interaction Paradigm
- 7. Human computer interaction (HCI) is the usability, functionality, and portability of computers. It is the study of how humans interact with computers physically and mentally. HCI is useful in the development of software because we need to build upon the understanding of how it will best be interacted with and how the human component can solve their problem using the software program or operating system and to incorporate the use of the software into new devices that allow fore more portability and more/new integrations of devices into our physical environment.
