changing an operating system......... An operating system is the program that manages all the application programs in a computer system. This also includes managing the input and output devices‚ and assigning system resources. Operating systems evolved as the solution to the problems that were evident in early computer systems‚ and coincide with the changing computer systems. Three cycles are clear in the evolution of computers‚ the mainframe computers‚ minicomputers and microcomputers‚ and each

Android Operating System Android is an open-source software stack for mobile phones and tablet devices. Android was originated by a group of companies known as the Open Handset Alliance‚ led by Google. Today‚ many companies have collaborated in the creation and development of the Android operating system. The members of the OHA contributed in the form of allocating significant engineering resources to improve Android and bring Android devices to Market. (Open Handset Alliance‚ n.d.) According to

EVOLUTION OF THE OPERATING SYSTEM Operating systems as they are known today trace their lineage to the first distinctions between hardware and software. The first digital computers of the 1940s had no concept of abstraction; their operators inputted machine code directly to the machines they were working on. As computers evolved in the 1950s and 1960s however‚ the distinction between hardware such as the CPU and memory (or Core as it was called then) and the software that was written on top of it

April 9‚ 2012 Terance Carlson This paper will discuss three main operating systems‚ Windows‚ Linux‚ and OS X. All three of these operating systems have features which are unique unto themselves. Although there may be arguments as to which one of these three operating systems is better it really all comes down to what features are needed for each user. This paper will describe the features that each of these operating systems has to offer. First‚ Microsoft Windows. Microsoft began its dominance

ROS (Robot Operating System) is a framework for robot software development‚ providing operating system-like functionality on top of a heterogenous computer cluster. ROS was originally developed in 2007 under the name switchyard by the Stanford Artificial Intelligence Laboratory in support of the Stanford AI Robot (STAIR[1]) project. As of 2008‚ development continues primarily at Willow Garage‚ a robotics research institute/incubator‚ with more than twenty institutions collaborating in a federated

Networking in Operating Systems Week 6 Check Point Networking in an operating system can be a daunting task is the User doesn’t know what they are doing. There are many advantages to networking. Sharing of data and resources can help to make a company run smoothly and more efficiently. How this happens is the connection of a workstation to a network. While a network is a group of computers attached to a wire‚ it has become much more complicated. The wire or connection is there for

System portability A major contribution of the UNIX system was its portability‚ permitting it to move from one brand of computer to another with a minimum of code changes. At a time when different computer lines of the same vendor didn’t talk to each other -- yet alone machines of multiple vendors -- that meant a great savings in both hardware and software upgrades. It also meant that the operating system could be upgraded without having all the customer’s
