2050243-MAJOR IX MODERN OPERATING SYSTEM 1. The operating system is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks‚ such as recognizing inputfrom the keyboard‚ sending output to the display screen‚ keeping track of filesand directories on the disk‚ and controlling peripheral devices such as disk drives and printers. 2. The kernel is a program that constitutes the

What are The Three Important Parts Of Unix Operating System‚ Explain Them? Answer: UNIX is an operating system which was first developed in the 1960s‚ and has been under constant development ever since. It is a stable‚ multi-user‚ multi-tasking system for servers‚ desktops and laptops. The UNIX operating system is made up of three parts; the kernel‚ the shell and the utilities (programs). THE KERNEL: The kernel of UNIX is the hub of the operating system: it allocates time and memory to programs

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

History of Operating Systems Early computers lacked any form of operating system. The user had sole use of the machine; he would arrive at the machine armed with his program and data‚ often on punched paper tape. The program would be loaded into the machine‚ and the machine set to work‚ until the program stopped‚ or maybe more likely‚ crashed. Programs could generally be debugged via a front panel using switches and lights; it is said that Alan Turing was a master of this on the early Manchester

Installing/Upgrading an Operating System Installing/upgrading an operating system or OS‚ is a rather simple procedure; however‚ any mistakes can have a profound effect on the computer’s ability to operate. Typically‚ most users do not have to deal with their computer’s OS as pre-built computers will have the OS already installed and rarely find the need or opportunity to upgrade it. There are a few circumstances that require a fresh install or upgrade for the OS such as installing newer

Operating system virtualization is a method of altering a standard operating system so it may handle multiple users all at the same time. These individual users would not have any interaction with one another. Their information would also remain separate‚ even though they are using the same system. While this technology has several uses‚ the most common uses are in hosting situations and server consoladation. With operating system virtualazation‚ a single system is set up to operate like several

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

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
