Why operating systems evolved from multiprogrammed batch systems to time sharing systems?
Simple batch system used to for long times and they occupy the CPU even when they are actually not utilizing the CPU for example while doing the I/O operations. So the programmers thought it to be great idea if some other process can use the CPU when the previous process is idle. In multiprogrammed batch systems one user can run multiple programs and which gets the CPU whenever the CPU is idle. So it speeds up the process completion.
How do you install the answer bar for 1-click answers?
I had Answers.com installed on my computer, I uninstalled it, thinking I could download it again and the sidebar would be there, I have had it for along time, and I would like to get it back. Can you give me some help in re-install Answers.com and with the sidebar and alt-left click
How could a system be be designed to allow a choice of operating from which to boot?
You have to have either two or more hard drives and set one to MASTER and the other to SLAVE then configure them in the BIOS.
Or you can have one hard drive with two or more partitions (each OS on its own partition) and configure them in your BIOS.
I know that vista and windows 7 will automatically give you the choice on which one you want to boot to when the OS's are on the same hard drive.
You might want to look into a virtual machine aswell, like virtualbox. They are pretty cool allowing you to run as many operating systems as you want at the same time.
No, it is not possible to construct a secure operating system for those computer systems which do not provide a privileged mode of operation in hardware.
Why do you prefer Linux operating system instead of windows?
There are a number of reasons why any given person may prefer a Linux OS over Windows, and which ones a Linux user values the most will vary from person to person. But generally they can be summed up as follows:
Relative Security - Because Linux has a much smaller number of users than Windows, it is less likely that criminal hackers will try and write viruses for a Linux system since the number of affected users will be lower. The number of variances in Linux operating systems also means that a Linux virus is less likely to affect all flavors of Linux, which brings us to another reason...
Number of Choices - There are literally hundreds of versions of Linux out there, so even if one doesn't quite suit you, this does not mean all is lost. Sadly, the sheer volume of options can be overwhelming to those accustomed to Windows, and this is one reason why Linux on the desktop hasn't caught on. Having a choice for an OS that is geared toward specific needs makes it a must-have for some (such as Backtrack Linux for security audits).
Customization - This usually applies to the extreme techies. Because the source code of any Linux OS is available, users can modify the code to their liking if they desire. This has led to the development of many newer variants of Linux - where people take existing code from Debian for instance, and then adapt that for another OS (such as Ubuntu) and then another more on top of that (as is the case with Mint).
There is enough modularity in most user friendly operating systems (such as Ubuntu or Mint) to modify them to a large extent even if you cannot code. But the open-source element that would allow a coder to create their own variant is itself yet another reason why people prefer Linux.
Production Approach - Linux is open-source while Windows is proprietary. Linux can be adapted and modified by anyone to their liking, which is appealing to those who are opposed to copyright restrictions on software. Anyone can contribute code to the Linux kernel or to a specific OS for potential inclusion. New releases appear much more often than Windows with most actively developed Linux distros.
Hardware Requirements - The overwhelming majority of all Linux distros require far less computational power to run. There are even some versions of Linux designed specifically for those with old or inexpensive hardware (such as Puppy Linux). This can lead to some performance gains and greater longevity for most computers compared to what you can expect from Windows. Faster boot times and less of a need for disk defragmenting (because Linux uses a different file system approach) are just a few typical benefits.
Overall it really comes down to the user which operating system is better for them. But in general the reasons elaborated above are some of the justifications for why one might prefer to use Linux instead.
Is Windows home server a fast and reliable self operating system?
Windows home server is fast and reliable. It allows users to backup up to ten personal computers and makes it easier to share data to all devices connected to the same network. It is designed so that users only need an ethernet card, and it is compatible with Windows XP, Windows Vista, and Windows 7.

What is the difference between computer structure and computer function?
i think computer structure is just a drawing of computer in a postal or book while computer function is just like the purpose of a computer.
What is the definition of open source OS?
Having the source code open for anyone to edit or modify for free.
Difference between system programme and operating system?
Operating systems are a type of System Software. They are supposed to act as an interface between the outside world and the Computer hardware, mainly dealing with allocation of memory, working of devices and so forth. Utility programsare also System software but they are aimed at maintenance of the system e.g antiviruses and disk defragmenters. P.S There is no term such as system program.

The difference between in-house software and off the shelf system is?
In-house software is software that is custom designed to suit your organization and meet all its specific needs. Off the shelf software is commercially developed software to do a job that a lot of people need done, which may not do everything that your organization needs it to do, but it covers a lot of it. Both options have their advantages, with in-house software often requiring dedicated developers and off the shelf typically being more expensive upfront and sometimes less functional in the long run.
