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

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

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

1. Introduction: An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs usually require an operating system to function. For any computer to function‚ it must have an operating system (OS). A powered computer with no operating system will only display coded text messages only understandable to the computer
