Most common operating systems being used today are Microsoft Windows, Mac OS, Linux and Solaris.

There are many functions that all operating systems share. All four of the major ones have to do with management, but more specifically, the management of memory, files, devices, and processors.

There are basically four types of operating systems. They include Batch Operating System, Multiprogramming Operating System, Network Operating System and Distributed Operating System.

Windows 8 is aimed at tablet computers but can be used on normal computers like desktops and laptop computers. Microsoft are hoping to take over the tablet market by making their operating system the best. But they have many rivals like Google and Apple with their operating systems for tablet. At the moment Apple is known to be the best operating system for tablets and androids is currently the second best operating system for tablets. But apples operating System for tablet only works on an Apple device but with Google's android operating system they work on any tablet. So when Windows 8 comes out four tablet they will only have one rival that will be Google with their operating system for android.

AFAIK there are only 2. Hardware abstraction and resource sharing.

In short, yes, a user may have three operating systems on a single computer. A user may install as many operating systems as allowed by the partition table. A MS-DOS formatted drive (using Master Boot Record formatting) can support four partitions that can be marked bootable; in this case, the limit is four operating systems per installed hard drive. Computers can have multiple hard drives installed, in which case the limit still applies. A computer with four hard drives installed can boot from one of sixteen different operating system partitions, assuming that it has the capability to boot from a non-primary disk (most modern computers offer this option). The previous paragraph assumes that the Microsoft Windows boot loader (NTLDR) is used. If GRUB (the Linux boot loader) is used, it can address any partition on any drive that it supports, potentially allowing a user to boot to dozens of operating systems on a single computer. The partition table will still play a limit on this role, as MBR will never support more than seven partitions in total. A UEFI-compatible system is likely capable of booting far more operating systems on the same amount of hardware. In theory, this would allow 128 separate partitions, so the system could boot into a myriad choice of operating systems. One should note that all operating systems must share the same physical space. This makes it unlikely that a 40GB drive would comfortably hold three or four operating systems (Windows 7, for example, needs up to 20GB by itself). Most modern drives are 500GB or larger, so three operating systems would have about 150GB of usable space if it were split evenly.

Automating tasks using operating systems provides convenience to the users. Examples of automated tasks are: scanning, performance checks, reboots and security sweeps.

Operating Systems, Applications, Drivers, and Programming Languages are the four categories of software. Each of these types of software is needed in order to use a computer.

Operating systems 1) control hardware access, 2) manage files and folders, 3) provide a user interface, and 4) manage applications.

Windows operating systems send four pings only, because it's normally enough to ensure that a devices is alive. Other operating systems (UNIX, Linux) send continuous pings until Ctrl-C is pressed.

Types of Operating SystemsWithin 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" when delivered for use. A very important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time, every time it occurs. In a complex machine, having a part move more quickly just because system resources are available may be just as catastrophic as having it not move at all because the system is busy.Single-user, single task - As the name implies, this operating system is designed to manage the computer so that one user can effectively do one thing at a time. The Palm OS for Palm handheld computers is a good example of a modern single-user, single-task operating system.Single-user, multi-tasking - This is the type of operating system most people use on their desktop and laptop computers today. Microsoft's Windows and Apple's MacOS platforms are both examples of operating systems that will let a single user have several programs in operation at the same time. For example, it's entirely possible for a Windows user to be writing a note in a word processor while downloading a file from the Internet while printing the text of an e-mail message.Multi-user - A multi-user operating system allows many different users to take advantage of the computer's resources simultaneously. The operating system must make sure that the requirements of the various users are balanced, and that each of the programs they are using has sufficient and separate resources so that a problem with one user doesn't affect the entire community of users. Unix, VMS and mainframe operating systems, such as MVS, are examples of multi-user operating systems.

There are four main classifications of computers: main-frame, minicomputer, microcomputer, and handheld.

The four numeric systems are Roman, Alpha, Mayan, and Arabic.

super computers ,microcomputers ,minicomputers and mainframe

Servers and workstations, including supercomputers Personal computers Laptop computers Notebook computers and pad devices

the four operating system found in the windows 2000 suite are : windows 2000 professional windows 2000 server windows 2000 advanced server windows 2000 datacenter server

The computers are broadly classified into four categories. The four categories includes the microcomputers, the minicomputers, the mainframe computers and the supercomputers.

There are four methods to connect two computers. You can connect via network cable USB data link cable, wireless router or Bluetooth. Choose a method then refer tp the Operating System handbook for your computors. Windows based systems are easier to network than trying to network a mixture of OS's

The general purpose computers (GPC's) were 5 IBM AP-101 computers - a set of four running the Primary Flight System software, and one running the Backup Flight System Software.

Any operating system will use a quad core processor, but many of the older operating systems cannot use the multiple cores-- they simply weren't programmed to do so. In general, anything produced within the past couple years will utilize a quad core processor. Many applications, however, are not programmed to use four cores, though there is a growing acceptance to use multiple cores to speed the process. As for operating systems, any recent Linux distro, Mac OS X, Vista and Windows 7 will use four cores, but in general, the newer the OS, the better the utilization of all four cores.

Well, the most fundamental probably are:- processor management- memory management- file management- device management (in some OSes, devices are represented as files)what are the four functions that all operating systems provide?
