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

Operating System Basics Functions of Operating Systems • An operating system is the software on a computer that manages the way different programs use its hardware‚ and regulates the ways that a user controls the computer. • Provide a user interface • Run programs • Organized file storage Types of Operating Systems • Real-time operating system – Very fast small OS – Built into a device – Respond quickly to user input – MP3 players

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

Components of an Operating System In order to perform the actions requested by the computer’s users‚ an operating system must be able to communicate with those users. The portion of an operating system that handles this communication is often called the user interface. Older user interfaces‚ called shells‚ communicated with users through textual messages using a keyboard and monitor screen. More modern systems perform this task by means of a graphical user interface (GUI) in which objects to be

Types of Operating Systems Within the broad family of operating systems‚ there are generally four types‚ categorized based on the types of computers they control and the sort of applications they support. The categories are: * Real-time operating system (RTOS) - Real-time operating systems are used to control machinery‚ scientific instruments and industrial systems. An RTOS typically has very little user-interface capability‚ and no end-user utilities‚ since the system will be a "sealed box"

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

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

HISTORY OF OPERATIMG SYSTEMS Operating systems (OS) provide a set of functions needed and used by most application programs on a computer‚ and the linkages needed to control and synchronize computer hardware. On the first computers‚ with no operating system‚ every program needed the full hardware specification to run correctly and perform standard tasks‚ and its own drivers for peripheral devices like printers and punched paper card readers. The growing complexity of hardware and application programs

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

Chapter 1 1. What is free software? List three characteristics of free software. Free software is software that users have the freedom to distribute and change. The three main characteristics of free software are: The source code has to be distributed with the program‚ you cannot restrict people from redistributing/modifying/using the software‚ and users must be allowed to redistribute modified versions under the same terms/licensing. 4.
