Operating Systems

Google operates in California, USA.

Their workplace is called the 'Googleplex'.

To find the current OS, go so Start - Run - type into the box 'dxdiag', hit enter and it will tell you.

Single-threaded processes only have one thread of execution -- therefore it would not be possible to have two processes waiting for input at the same time.

Some pros and cons of GUI in operating system are:

Pros:

-Easy to learn

-Harder to make mistakes

Cons:

-Slower if you know what you want done

You can't technically open MS DOS in notepad, but you can make files that MS DOS can use in notepad. For instance, you can create SYS, INI, BAT and others in notepad to make the computer do something, but MS DOS it self is dead. DOS will never die because of what it stands for. "Disk Operating System" You need a disk to run anything. Your hard drive is nothing more than a bunch of high tech cds spinning your files around.

M.C.A could be almost anything, maybe a name of a school or school department?

Lex (short for Lexical Analyzer)`is a specialized programming language that takes a set of specifications for how to scan text and find specific items in the text and generates C language source code that is compiled with other code to actually perform the work. The code generated can be used as part of a compilers lexical scan, scanning for specific words and symbols.

The processor time is a function of the processor. The memory allocation is a function of the operating system.

One of the examples of this is Microsoft excel

No. Web browsers work on the system they were built for. Many (most?) modern web browsers have built a 'flavor' for the major OS's (Mac, Windows, Linux) and also now have x86 or x64 editions available. You still can't just take any old browser installer and toss it on whatever type of machine you have.

Internet Explorer, owned my Microsoft, is not likely to ever be supported on Linux, even though IE for Mac was the default browser from 98 through 2003 (MS and Apple had a 5 year contract for MS to provide a browser that worked on Mac OS, Apple replaced IE with their own creation, Safari, at the end of the contract).

Others, like Firefox and Chrome, are not made by people with an ownership stake in an operating system and many of these folks like using a variety of Operating Systems and still have their favorite browsers with them.

Add Safari into that mix, and you'll find it's not officially supported on Linux, but there is of course a Windows version to help try to gain market share for it.

Then you get into older browsers, like Netscape Navigator, Slipknot, and older versions of browsers that are still being made (Internet Explorer 1.0, Firefox 1.0) and you'll find that they're not supported on anything, as they are past their life cycle and were designed for operating systems that are no longer in use (Windows 95/98/ME, Apple Mac OS 1/2/3 etc.) and even though they MIGHT run, at least partially, on current operating systems, they are bound to have errors, issues, or funkiness someplace. It's like saying since humans live on a planet, we can obviously live on Mars. Well, we might be able to do so, but not without some very extensive special accommodations being made.

Asymmetric multiprocessing - In asymmetric multiprocessing (ASMP), the operating system typically sets aside one or more processors for its exclusive use. The remainder of the processors run user applications. As a result, the single processor running the operating system can fall behind the processors running user applications. This forces the applications to wait while the operating system catches up, which reduces the overall throughput of the system. In the ASMP model, if the processor that fails is an operating system processor, the whole computer can go down.

Symmetric mMultiprocessing - Symmetric multiprocessing (SMP) technology is used to get higher levels of performance. In symmetric multiprocessing, any processor can run any type of thread. The processors communicate with each other through shared memory.

SMP systems provide better load-balancing and fault tolerance. Because the operating system threads can run on any processor, the chance of hitting a CPU bottleneck is greatly reduced. All processors are allowed to run a mixture of application and operating system code. A processor failure in the SMP model only reduces the computing capacity of the system.

SMP systems are inherently more complex than ASMP systems. A tremendous amount of coordination must take place within the operating system to keep everything synchronized. For this reason, SMP systems are usually designed and written from the ground up.

example on round robin problem in OS:

let here p1,p2,p3,p4 are some process and its burst time is given as:

P1=6

P2=8

P3=2

P4=4

time quantum=4 millisec

PROCESSES P1 P2 P3 P4 P1 P2

CPU CYCLES 0 4 8 10 14 16 20

SO in this example, a process cannot exceed more than 4 millisec. so each process is not exceeding more than 4 millisec. as p1 starting time is 0 ms and ending time is 4 ms then another process started at this time which also complete 4 cycles then another process p3 start which need only 2 cycles to complete its execution ,so goes only 2 cycles and finish its execution at time 14 and p4 complete its execution at 14 . now dis process will again started until all the process does not complete its execution remaining in the time quantum limit.

Many Unix and Linux servers come without a graphical user interface, and the text mode interface is the default.

For those systems using a GUI, there is a 'terminal' tool that you can select from the menu to allow text interactions.

Operation buffering includes running interference in operations management. This includes parceling tasks to improve speed and efficiency. This allows cooperation and collaboration through the buffering agent for the benefit of the project.

the OS handles it by writing a page fault interrupt handler. The first thing the page fault handler will need to do is to determine the address of the page fault; you can find out this address by calling the Get_Page_Fault_Address() function (prototype in . Also, the errorCode field of theInterrupt_State data structure passed to the page fault interrupt handler contains information about the faulting access. This information is defined in the faultcode_t data type defined in. Once the fault address and fault code have been obtained, the page fault handler will need to determine an appropriate action to take

The current version of the Stykz animation software does not support sound. It is planned to add this feature in version 2 of the software.

A workaround option at the moment is to export the animation as a Quicktime movie and then add the music to the movie file.

okay see that paragraph is true but there is a way around it all you have to do is save the stykz file into movie maker and then add sound there

Alright, the problem with ^ that answer is that, some people don't use the Movie Maker and/or don't want to. The easiest way is the first answer above. Although, people still can use the second answer.

interrupts are used to ensure adequate service response times by the processing.

Operating System Zoo is a website that hosts disk images of free an open-source operating systems for use in virtual machines and emulators.

Poorly.

1. Right click the .exe and click properties.

2. Go to the compatibility tab and make it run as Windows NT, with low colors, resolution and as administrator.

3. Open any text editor write:

taskkill /F /IM Explorer.exe

dmcr.exe

Start explorer.exe

4. Save as SEWars.cmd

5. Run the new file to start your game.

Device manager.

If your OS is installed on that drive yes the OS will be deleted but if your OS is on another hdd then the OS wont be deleted unless you format that other drive.

if drive C: has your OS and everything else on it and you format that it will all removed nothing will be left behind.

But say you had Drive I: with your OS on it and drive C: with all other data on it and your formatted drive c you would not remove the OS unless you formatted drive I:

Different types of operating systems have their disadvantages. In the case of a single user OS, it does not use the CPU, memory and other resources to the maximum. It also wastes a lot of CPU time since it executes one program at a time.
