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

Xenix- a discontinued Unix operating system What is Xenix? Xenix is an operating system‚ which supports a computer’s basic functions. It is a discontinued version of Unix‚ a set of operating systems. Xenix was created by Bell Labs‚ which was part of the Bell System‚ and was owned by AT&T. Due to an antitrust case‚ which aimed to prevent AT&T from gaining control of the market‚ they were initially forbidden from entering the computer market. This meant that they were unable to sell Unix directly to

don’t override the changes of another user. 3. 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

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

Questions: Dakota Office Products 1. Why was Dakota’s existing pricing system inadequate for its current operating environment? Dakota’s existing pricing system was inadequate for its current operating environment because the pricing was based on traditional allocation of overheads. The result of which were that the actual costs incurred for fulfilling the orders of customers were not ascertained. There were two effects of this method. First‚ the overall prices of all the products increased

TYPES OF OPERATING SYSTEM Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main object of real-time operating systems is their quick and predictable response to events. They either have an event-driven or a time-sharing design. An event-driven system switches between tasks based of their priorities

Associate Level Material Appendix B LAN Operating Systems Scenarios Read the three scenarios below and answer the questions that follow each scenario. 1. You are the network administrator for a new company that has 10 users and that plans to add 5 more users within a year. The files need to be accessed by all 10 users‚ and each user must have different security rights. What kind of network would you install? How would the pieces and components of this network relate to each other? Define

1. In a multiprogramming and time sharing environment‚ several users share the system simultaneously. This situation can results in various security problems. a. What are the two such problems? Ans: The two problems in Multiprogramming and time sharing environment are Stealing or copying a user’s files; Writing over another program’s (belonging to another user or to the OS) area in memory; Using system resources (CPU‚ disk space) without proper accounting; Causing the printer to mix output by
