When computers need to use more memory than have RAM, they'll swap out pages of memory to their drive. When they need those memory pages, they'll swap out others and swap in the needed ones. If a computer needs enough additionall memory, it can get so busy swapping that it doesn't have any (or very little) time to do any useful work. That is called thrashing.
Unix calls swapping swapping. Windows calls it paging, probably because of the memory pages. Memory pages are 4096 (4KB) sections of memory.
Unix drives are usually partitioned with a swap partition, and swap files can be made in the filesystem. Windows just has pagefiles[s].

Answer:(1) To manage the computer's resources, which includes central processing unit, memory, disk drives, and printers, (2) To establish a user interface
(3)To execute and provide services for applications software.
The old mainframe computers have
(1) low memory sizes
(2) slower connectivity speed
(3) Larger sizer
(4) low sophistication.
Explanation: Operating system is a system software that manages the computer resources,helps to establish user interface and it helps to provide services for application softwares.
Operating system software includes WINDOWS X,WINDOWS 7,WINDOWS 8,LINUX,etc.
Mainframe computers are computers used by large multinational companies for processing bulk data. Old mainframe computers were produced by IBM(INTERNATIONAL BUSINESS MACHINE) in the year 1952 they are classed two scientific and commercial mainframe computers with different information although they had some incompatibilities. Old mainframe computers are large in size with low processing speed, sophistication and storage compared to present day system.
The correct answer is centrifugal force.
The force that pulls out from the center on a body that is in a circular motion is called centrifugal force. This force increases as the speed of motion increases. It is centrifugal force that results in a strong outward pull on your vehicle traveling around a corner.
