This is not complete list, but few other operating systems are used by anyone else than hobbyists.

No, but most of Linux software can be run on other systems since most of them are portable.

Also called FIFO anomaly. Usually, on increasing the number of frames allocated to a process virtual memory, the process execution is faster, because fewer page faults occur. Sometimes, the reverse happens, i.e., the execution time increases even when more frames are allocated to the process. This is Belady\'s Anomaly. This is true for certain page reference patterns.

windows 7 is the latest version of a series of operating system that Microsoft has produced for use an personal computer.It is a follow up to the windows vista OS which is released in 2006. An OS allows your PC to manage software and perform essential tasks. It is also a GUI,Windows 7 has 4 default libraries for documents, music,videos and pictures.

1. The Title bar gives the name of the document and the program being used

2. On the right side of the Title bar are three buttons.

a. The Minimize button makes the window disappear from the screen without closing

the program. You can bring the window back by clicking on its button on the Task

bar at the bottom of the screen.

b. The Reduce/Maximize button makes the window smaller or takes it back to full size.

c. The Close button closes the document or program.

3. The Menu bar offers dropdown menus for things you do in Microsoft Word.

4. The Toolbars display icons that perform specific tasks when clicked. Often the toolbar icon performs the task without offering any options.

5. The Rulers display the tabs, indents, margins and give the user a visual guide for alignment.

a. Tabs are set on the ruler by clicking the spot on the ruler where you want to the tab to

start. Different Tab settings can be used to align text, decimals and indents.

b. Indents and margins can be set with the handles.

6. The Document display window is where the current document is visible.

7. The Scroll bars allow the user to move up and down the document in the window.

8. The Status bar shows the location of the cursor, number of pages and includes advanced toolbar options.

9. The Task bar displays buttons for Open programs or documents. Clicking on a button on the taskbar, brings that program into view. The current program button looks indented.

Hardware configuration problems were much more common before Plug and Play standards, which are a set of protocols by hardware and operating system vendors relating to hardware installation. With plug and play an operating system can often recognize the existence of a new hardware component and select configuration options that permit the component to communicate successfully with the operating system.

A partitioned memory management technique is when the operating system loads more than one application program into memory at the same time, they share memory space and cpu time.

The main memory (which is the volatile memory where active programs and data are held during use), is divided into partitions that different processes that are running can fit into. The partitions sizes can either be fixed, or they can change to encompass the size of the process that is to be run.

So, a fixed partition main memory management technique is when the main memory is divided into partitions that do not change based on the size of the process, they are a fixed size. And a process is loaded into a partition big enough to hold it.

It is because there are more than one options and different people prefer different operating systems. Some like the freedom and customisability of Linux, some like to use Apple products (OSX), and some like he familiarity of Windows. That's way there is no common OS.

The format command on its own - erases the reference track of the disc - removing the title(s) of any files and marking any used sectors as usable again. Adding the /s tag to the format command has the additional function of copying two (normally hidden) files - Autoexec.bat & Config.sys to the disc once the format command has been executed. This tells the computer that the disc can be used to boot-up the system when it's switched on.

Sorry, but not that I know of. Python is only available on Mac OS or Windows. You would also need a code editor which is only on a PC.

HIdden24 offer a VPN-service that lets you be protected from security threats online. Example - protect your privacy & prevent identity theft when connecting a computer or phone to a public wifi, or prevents your ISP to see your Google searches.

Reliability, security, cost, performance, and compatibility.

Most if not all of BSDs are distributed under variations of the Berkley license. I'm not sure if every single one has qualified with the Open Source Initiative : http://www.opensource.org/licenses/alphabetical

OSI is probably the most agreed upon (not actually agreed upon, just the most) authority on what is open source and what isn't.

Conclusion: OpenBSD is in an open source system. It is not a GPL style open source system in that is generally more permissive of copying, barring distributions prior to 1999 that had clauses affecting advertising that were later removed.

its quite easy actually...always install the earliest OS first...in your case, install 98 on whatever drive you wish and after it is complete...install xp on the other. during boot, you will be given the option to boot what ever OS you wish.

I tried your sugestion, loaded 98 first on the first drive, xp on the second drive...it does not work, only boots into 98

XP should be loaded with both of the drives connected. After loading 98, do not make any hardware changes. Just go and load XP onto the second drive. XP will create some files on the 98 drive that will bring up an OS menu at boot time allowing you to choose the OS of your choice. It will only show for about 30 seconds. Maybe you just weren't at the computer when it displayed.

The amount of time that the OS selection menu appears, and the OS that the system defaults to can be customized to boot into Win98 or WinXP if no action is taken by the user. You could configure a computer to allow it to boot into Win98, WinME, Win2000, and WinXP, if you wanted to. You could also have it boot to three different Win2000 installations if you wanted to.

A few tips to follow. Always install the older operating system first (i.e. Win98, then Win2000, and then WinXP.) Don't change drive letters after installing. Changing major hardware components will likely require reinstalling everything all over again. So, keep your motherboard the same. Changing a motherboard prevents the operating systems from booting because they don't have the drivers for the new hardware, and therefore, can't utilize them.

There is more than one operating system, and there are many manufacturers.

* Windows - Microsoft Corporation * Mac OS X - Apple, Inc. * Red Hat Enterprise Linux - Red Hat, Inc. * SUSE Enterprise Linux - Novell, Inc. * Ubuntu - Canonical Ltd. * QNX - QNX Software Systems * VxWorks - Wind River Systems, Inc.

Multitasking.

In computing, a distributed system is a system that works in different locations or work using separate processing or processors to their jobs, often simultaneously. Data can be stored in different locations in a distributed database, although a user won't know it. The data will appear on their screen when they access, so they are unaware of its location. Networks use distributed systems to link up systems that work together but are in separate locations. If there are full copies of data in various locations, then if one location gets damaged or inaccessible, the system can still function. This makes data and systems more secure.

Software has to be written to run on a particular operating system. While there are lots of programming languages that will run on many operating systems, a compiler or runtime engine has to interpret the programming language and translate it into commands that the operating system understands. The Operating System is the foundation of the building. Applications are the structure built on the foundation.

Don't know if you are talking about any specific application but to view desktop icons, right click on desktop go to 'view' and select/check (if unchecked) 'show desktop icons'.
