operating system
More than one user can use the mainframe at once.
One example could be the expansion of the thirteen colonies. Another example could be Indian Reservations.
The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.
Practically all of them have O.S's, as I doubt that most people will ever see one without some mac o.s on it or xp or vista on it. However, all stock machines that are loaded/downloaded/installed with programs/software,etc come without operating systems. I have seen my share of them, as I used to work for a computer store myself, though DOS is nothing to brag about, unless you are some nerdy IBM veteran that designed it.
They built a system of storehouses in which surplus grain was kept.
i have no frekin clue
A Disk Utility is an application that is built into the Macintosh operating system. It allows one to format, modify and/or erase a hard drive, either internal or external, that is hooked up to one's Macintosh computer.
An Operating System manages resources. Memory is one example of resource management.
Probably the Xerox one for their experimental prototype Alto computer workstation. That inspired Jobs and Wozniac of Apple to make the one on the Lisa, then the Macintosh.
One example of a time-sharing system is the bank's bankcard system, which allows hundreds of people to access the same program on the mainframe at the same time. The Multics & Unix operating systems are time sharing Operating Systems
By system software, do you mean the Operating System; Window 7 being one example? I use Ubuntu on most of my computers.
Open source, such as one of the Linux variants; Ubuntu, or Kubuntu, for example.
Micro-Kernel: A micro-kernel is a minimal operating system that performs only the essential functions of an operating system. All other operating system functions are performed by system processes. Monolithic: A monolithic operating system is one where all operating system code is in a single executable image and all operating system code runs in system mode
The two concepts build upon each other. A single tasking (ST) operating system is necessarily a single user (SU) operating system, but a single user operating system may be a multi-tasking (MT) operating system. For example, MS-DOS is a SU, ST operating system (there was only one "user" and only one program could run at a time), Microsoft Windows 3.1 was a SU, MT operating system (only one user could be logged in at a time, but multiple tasks could run at once), and Windows XP is a multiple user (MU), MT system, as multiple users could be logged in at once, and multiple tasks could be run at once. There is no known example of a MU, ST operating system.
Microsoft is not an Operating System.
Yes. Windows 7 is a system distribution in the Windows family built around Microsoft's proprietary NT operating system. Ubuntu is also one of many Linux distributions built around the open source Linux operating system.
