What is computer operating speed?
Computer operating speed is generally the speed at which the CPU operates, known as the clock speed. It is expressed in Mega-Hertz or Giga-Hertz. For example a Pentium M processor running at 1.8 Gigahertz is being clocked internally at 1.8 GHz.
Difference between operating system software utilities and drivers?
OS is a software that enable user to command the hardware
software utilities are programs to help/improve a specific job of the OS.
drivers are program that tells the OS how to let user command the specific device the driver is for.
How do you define a process in rtos?
RTOS(Real Time Operating System) can execute multiple programs concurrently. At any time there may be tens of programs executing on a RTOS. A program in execution is called a process. SOMA VARMA G
Is programming language an example of software application?
No. An application is written in one or more computer languages and performs specific tasks. An analogy would be English is a language, a book is written in English.
Briefly explain why software applications and operating system software are periodically updated?
When a software is manufactured or compiled, it is not the best of the lot. While using the same or exploring the same, many bugs and problems can be identified, which need a rectification. These rectifications come in form of updates. Further, more enhancements to a utility/app like more languages support, etc. comes in form of updates. Antivirus suites are updated to update the Virus signature database in order to secure the system.
What is exokernel operating system?
EXOKERNEL-
The exokernel architecture is designed to separate resource protection from management to facilitate application-specific customization. Exokernels are typically small in size because of their limited operability.
Conventional operating systems always have an impact on the performance, functionality and scope of applications that are built on them because the OS is positioned between the applications and the physical hardware. The exokernel operating system attempts to address this problem by eliminating the notion that an operating system must provide abstractions upon which to build applications. The idea is to impose as few abstractions as possible on the developers and to provide them with the liberty to use abstractions as and when needed. The exokernel architecture is built such that a small kernel moves all hardware abstractions into untrusted libraries known as library operating systems. The main goal of exokernel is to ensure that there is no forced abstraction, which is what makes exokernel different from micro- and monolithic kernels.
Some of the features of exokernel operating systems include:
· Better support for application control
· Separates security from management
· Abstractions are moved securely to an untrusted library operating system
· Provides a low-level interface
· Library operating systems offer portability and compatibility
The benefits of the exokernel operating system include:
· Improved performance of applications
· More efficient use of hardware resources through precise resource allocation and revocation
· Easier development and testing of new operating systems
· Each user-space applications is allowed to have to apply its own optimized memory management
Some of the drawbacks of the exokernel operating system include:
· Reduced consistency
· Complex design of exokernel interfaces
How would you notify users that you're going to reboot in ten minutes?
This has traditionally been a feature of multiuser operating system that the command the system operator uses to command a reboot or shutdown allows the system operator to specify this time interval, then automatically notifies all logged in users to complete what they are doing and log off before that time runs out. Any users failing to log out before the time specified by the system operator expires will be automatically logged out and their tasks killed at the last moment before the system automatically reboots.
Regardless of the size of the computer do most operating systems provide similar functions?
An operating system's primary goal is to provide an abstraction for applications to interact with users (get user input), and interact with hardware devices (provide output for users). At the most basic level, all operating systems provide these two types of services. Additional services, such as security, are a feature only on certain operating systems. Generally speaking, operating systems provide access to permanent storage systems, such as disks, printers, and keyboards.
Which is the best operating system for student?
I think Windows XP because it is the most known, the most used and the most easy to use. It can open all softwares that you need.
however my dad says xp is highly unstable he thinks that windows 7 is best but il leav tht up 2 u (although i also prefer XP)
What was the operating system of first generation?
Most first generation computers had no operating system. When they did, it was usually just something called a Batch Monitor, all it did was sequence through several jobs one at a time that had been submitted in a batch. The computer companies saw no need for any form of operating system, so the machine's users had to write them all themselves. It was not until the second generation computer that computer companies supplied operating systems for their computers and the earliest of these were simply adaptations of operating systems written by users of first generation computers with a few extensions.

Why might an operating system on a virtual machine run slower than one installed directly on a PC?
any high end database(datacenter) server, exchange server, any high end appliaction server which require dedicated physical resources will work better on physical then virtual. They will work slow on Virtual servers
What is the main advantage of selecting a 64bit operating system over a 32bit operating system?
It isn't an issue of advantages, it is an issue of compatibility with your computer. The 64 bit operating system can take full advantage of the capabilities of a 64 bit microprocessor, if your computer has a 64 bit microprocessor. However a 64 bit operating system will not run at all if your computer has an older 32 bit microprocessor; you will have to use a 32 bit operating system on that computer.
What are the differences between service operation and manufacturing operation?
According to the American Heritage Dictionary, a manufacturer is a person, an enterprise, or an entity that manufactures something. Therefore, a manufacture operation is a company or a factory where products and merchandise are made. Raw materials are used to manufacture these products and are then turned into finished goods ready to be sold. Anywhere from textiles to machinery, a manufacture operation should aim to make high quality finished goods. A manufacturer is a very important element in the selling process because without them, the products we need, use and enjoy would not exist. A service operation is a business or company that provides intangible, perishable goods or services to the public. According to statistics, eighty percent of jobs in business are in services. Services play a major role in manufacture operations and vice versa. According to out text book, services related to products now represent ten to thirty times the annual dollar volume of the underlying product sales. There are two key differences between service and manufacture operations; one, the natur......
Why is there more than one operating system?
Because not all operating system are perfectly suited to all tasks. You wouldn't haul grain in a Cadillac, and you wouldn't want to ride in the back of a Peterbilt after your wedding. The same goes for operating systems. While some are extremely versatile, they may not be able to fill that tiniest little niche that almost no one thinks of, so an operating system needs to be written for that task.
What are the 3 major operating systems?
The top three operating systems in terms of market share are Windows, Mac OS X, and Linux.
Operating System is a system software which allow us to have a direct interface with the hardware without knowing the complexity involved in the background. In simply words, it puts use of computer hardware. To the point of definition, a software allowing you to mobile hardware installed in your phone is also a operating system.
What is a Call center operator?
A call center operator is a person who works for an answering service. You answer calls for doctors and dentists and the like after hours. They usually are open 24/7 so you work shift work.
An operating system can be defined as a global application that acts as an intermediary between a computer user and the computer hardware. It manages the hardware and software resources of a computer. It allows the computers to run programs. An operating system allows the computer to start and function. It allows you to navigate your computer. It allows all the components of a computer to operate together to do tasks such as printing text to a printer. A word processor application sends its print request to the Operating System and the operating system carries out that task. A computer would likely be unusable without an operating system, unless the software is able to act as its own OS.
The goals of Operating system is to execute user programs and make solving users problems easier, to provide a convenient environment for the development and execution of programs, and to schedule computational activities to insure good performance of the computing system. Some operating systems are more user friendly than others. Ideally, the system should include easy to use icons, and easy to use pop-up instructions as needed. It can either be a graphical user interface (such as Windows, Mac, OSX) or a command line (Linux/Unix/DOS). It is the background in which all other applications and services run.
An operating system has two primary functions. Firstly, it dictates to application programs what they can and cannot do. Secondly, it manages the computer hardware on behalf of applications. The two functions are not unrelated.
It also manages execution of user programs to prevent errors and improper use of computer and operations and controls of I/O devices. If you had two applications, A and B running on the same computer, and no operating system to supervise them, then program A could overwrite the memory occupied by program B, or vice versa, program A could overwrite program B's files on disk. You could have the two programs trying to read from the same keyboard, or print on the same printer, simultaneously, and so on.
Additionally, if there was no operating system to manage the hardware, then applications would need to concern themselves with the minutiae of how to save data to disk by programming the hard disk controller, or obtain input from the keyboard by interrogating the keyboard controller, instead of getting on with the calculation of somebody's payroll, or whatever else that application was supposed to do. Computers with no operating systems relies on the application programs to manage minimal hardware. For instance, application programs would need I/O support libraries.
What is multitasking Linux operating syatem?
