Operating Systems

Preemptive Multitasking basically involves the operating system sharing CPU time among many processes. An executing process is terminated when its time slice finished and the the CPU control is given to the next process. All processes get CPU time.

In Cooperative Multitasking, however, one process can hold the CPU for as long as it needs it. For the cooperative to work, all programmes must cooperate, hence the name.

The CPU is connected to all the peripherals, which include the keyboard, the monitor, the speakers, and anything else that is connected to your computer. Strictly speaking, the CPU is physically connected to the motherboard.

NFS is the Network File System, and allows directories from systems to be used in other systems in a sharing arrangement.

in multiprogramming system, when two or more user use program or file at same time. the MMU of OS share pages of the process with the users. these pages is called shared pages

linux uses alot less ram than windows 7 (the more ram used the slower the computer). therefore linux makes your computer run faster

Most output devices are universal to various operating systems. Such as, your television or maybe even your stereo. Universal operating system can also be referred as a remote.

A tax sytem is used to help fund public projects and help pay for the government.

It all depends on if the website is active and has many visitors. You can look into starting a blog with the website called blogger or wordpress or grabbing your own domain name from Godaddy and getting some website and webhosting from TemplateDrop with nice website templates, ready to go. Adobe Photoshop, Adobe Frontpage, Dreamweaver, and Adobe Flash are a few tools that web designers use. Yes, all of this may seem a bit much but that's why colleges are offering BA's in web design now. My advice is for you to use website templates.

operating system is nothing but a communication medium between computer system and users.

Resolved: If you just want to un-clutter your user folder as I did, simply right click them then go to properties and click hidden, then apply.

Modifies and Programmed for general computing purposses.

This depends on what you're going to be using the computer for.

If you plan on using it for movies, photos and daily activities like note taking and surfing the web your going to want are larger hard drive to store all your data. Aim for 750 gb to 1 tb.

If your editing pictures and movies you'll want the larger hard drive along with higher RAM and a stronger CPU. Nowadays many editing software will come with multi-core support so getting a quad-core or higher will be a bonus.

If you plan on playing graphic intensive games you'll want everything listed above along with a video card. An onboard graphic card is okay if you just want to get by, but aim for a separate video card that is not onboard.

It is basicaly the spine of your computer. Its purpose is to run programs and such. Without it youd just have a box and a screen with fancy wires.

Unix was rewritten in the C programming language and not in assembly language. The migration from assembly language to the higher-level language C resulted in much more portable software, requiring only a relatively small amount of machine-dependent code to be replaced when porting Unix to other computing platforms.

Unix manages the hardware and the executing processes by the kernel. The kernel is a collection of programs written in C which directly communicate with the hardware. applications communicate to system using kernal. Hence kernal need to be changed for different hardware but user interface remains same.

Earlier versions of windows like 98 were fastest, but lack security and graphics.

comparing xp, vista,windows7 the order of speed is

vista<windows7<xp

(slowest)---------(fastest)

Both are software, operating system is software that will make your computer boot up and run. while Application software is a program that will run on a functional operating system.

It's an economy controled by a central administrater

The operating system is that expert software that allows the computer operator to feed in instructions to the computer. It governs how the installed software will run.

This would be the operating system (or OS). The operating system controls and/or maintains the operation of a computer and its devices. Among other things, the OS manages the memory, does traffic control for the various programs, and loads drivers to control the low-level hardware functions to make the devices usable,
