By first loading a small bootstrap program. The bootstrap program then loaded the OS.
It is still done this way, except the bootstrap programon most modern computers is preloaded on ROM so it needs no special action on the part of the operator/user to load it as was needed on the early computers.
Some early computers used a 2 stage bootstrap to simplify thing for the operator/user: the small bootstrap program loaded a larger more powerful bootstrap program, which then loaded the OS. This is not necessary with the bootstrap program in ROM, the large bootstrap program would be the one in ROM.
Operating system must be loaded first so that other applications and programs will be able to work.
The OS is stored in the Hard Drive then when you load up your computer it is loaded into the ram
System software that is responsible for the functioning of all hardware parts and their interoperability to carry out tasks successfully is called an operating system (OS). OS is the first software to be loaded into computer memory when the computer is switched on and this is called booting.
When you boot a computer, you are basically loading the operating system and all of its components. These are necessary for the computer to run and to access your data and software. After the OS has loaded, your startup programs are loaded as well.
Usually it is installed on your HDD (Hard Disk Drive).
Probably the IBM 7090 in 1958 running IBSYS. IBSYS was originally developed on the IBM 709, but when it was introduced in 1956 of course it had no OS at all. Programs were all loaded and run manually.
If you have os x lion for mac
post, BIOS, The OS takes over, Files are loaded
An OS CD is a disc that contains the Operating System and from which you can install a fresh copy of the OS onto your computer. A modern OS is likely to come on a DVD rather than a CD.
no, nothing remains in ram after your computer is turned off (unless it's static ram but hardly anyone has that anymore) in sleep mode your OS does remain in ram but your computer isn't off in hibernate mode, your computer is off and your OS state is written to the hard drive, so that it can be loaded back into RAM more quickly
An OS reside in HDD, SSD, flash drive or CD/DVD. When you boot the computer the kernel is copied to RAM. Now other parts of OS will be loaded to RAM as and when required.
go into your bios
