3. Define: Open Source
3.1. pen source refers to a program in which the source code is available to the general public for use and/or modification from its original design free of charge, i.e., open. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community. Open source sprouted in the technological community as a response to proprietary software owned by corporations.
4. Define: Ram
4.1. RAM (random access memory) is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor.
5. Windows 8
5.1. Pro
5.1.1. Common User Experience Across Devices The new UI Will help merge the tablet and PC Markets and allow PCs to benefit from touch capabilities
5.1.2. WINDOWS TO GO- Windows 8 will run from USB drive even When older versions of Windows Are installed on the host
5.2. Cons
5.2.1. NO START MENU-Microsoft Has pulled the Start button off the Legacy interface, complicating any Windows 8 rollout in a corporate Environment.

6. Mac OSX
6.1. Pro
6.1.1. Rather than just making something larger, as is the case with OS X's zooming gestures, Windows 8 allows you to focus or pull out on levels of information detailRather than just making something larger, as is the case with OS X's zooming gestures, Windows 8 allows you to focus or pull out on levels of information detail

7. Linux Ubuntu 12.0
7.1. Pro
7.1.1. Linux, was once the play toy of computer hobbyists and workhorse of behind-the-scenes computing tasks (most of the internet is served up by servers running Linux, for example). These days, it has become a home computing and office platform for the common user as well.
7.1.2. Distributions such as Linux Mint and the increasingly popular Ubuntu were designed especially to be easy and non-threatening for the average user. Implementing Linux on an enterprise level can add up to huge savings: the operating system, and almost all of its available software (including the Microsoft-compatible Libre Office) are 100% free. (There’s no lack of available software, either–as you might expect of a platform built by computer enthusiasts!)
7.2. Con
7.2.1. Its biggest disadvantage is that its end-users and office workers are often scared of it at first.
