Why do some systems store the operating system in firmware while others store on disk?

It is a decision based on engineering tradeoffs made during the system design. Without knowing the system requirements and tradeoff options to address them it really isn't possible to say more.

Why do some systems store the operating system in firmware and other on disk?
The firmware usually contains all of the code necessary to boot the machine. If the firmware is damaged, the machine will be unusable. Give the relative difficulty of upgrading firmware safely, it is often better to place only immutable code in the firmware, and make any changes / fixes necessary to the operating system on disk.
What are 4 ways in which an operating system controls hardware and software on a computer?
as I remember it the main ways to control peripherals on a computer or computer based systems is software, mediumware, firmware and hardware, things may have changed since i was last at school, but it is worth checking out them all, mediumware may have evolved into firmware by now, but you never know, check it out :) So essentially you have hardware which is controlled by its firmware, the firmware is what the operating system (mediumware)uses to control the hardware, and the software is the part that interacts with the operating system (mediumware) to make it possible for anyone to use the hardware in a nutshell.
What is the operating system of a motorcycle?
Motorcycles do not have operating systems.
Difference between Time sharing operating system and batch processing operating system?
Differentiate between Simple Batch Operating Systems and Time-sharing Operating Systems
What is the Differences between an embedded Operating system and a personal PC Operating system?
Embedded operating systems cannot be replaced with other operating systems. embedded system are designed for dedicated applicationembedded system are tailored to specific application.
What is the different between operating system and router operating system?
A "router operating system" is called firmware. It runs a router. A regular OS (Operating System) runs your computer. Operating systems are provided by many different organizations and corporations. Firmware is provided by the manufacturer.

What operating system does the Nintendo DSi have?
It has its own firmware, it doesn't use an 'operating system' as such.
Why are Windows and Mac not considered Web Browsers?
Because they are operating systems! These operating systems (and others) support web browsers which are applications that run on the operating system.

What is a BIOS?
The IBM BIOS is the BIOS (Basic Input Output System), or firmware, of the original IBM PC. Most "PC" systems created to this very day maintain almost complete backwards-compatibility with the BIOS, in order to run older programs and legacy operating systems.
Is a bios internal or external device?
Neither. The Basic I/O System is a firmware program, in ROM, that provides the Operating System a software program, in RAM, with I/O drivers for the basic I/O devices implemented on the motherboard. This allows different motherboard vendors to implement those devices in different ways without having to modify the Operating System for each machine. Some Operating Systems that depend on BIOSs are:CP/MISISMSDOSWindowsIn systems that use BIOSs, the Bootstrap firmware loads the Operating System software and starts the Operating System. The Operating System then uses the BIOS for basic I/O, including loading advanced I/O drivers (e.g. drivers required by plug and play devices).
In addition to personal operating systems and server operating systems there are also mobile operating systems and?
Virtual operating system
What is fermware?
Firmware is probably what you want. Firmware, (as distinct to software and hardware) is a fixed computer programme that is not altered by the user. For example, when the maker of my digital camera believes he has produced an improvement to the operating system inside the camera, he will issue a 'firmware upgrade' and if I copy this into my camera, it will do new things. Similarly for CNC machines, aircraft operating systems and so on. Hope my interpretation of your Q was correct.
Why can't the computer be reprogrammed?
A computer is comprised of hardware, firmware, and software. While programming a single application running on top of an existing operating system may sound simple, designing computer architecture requires full understanding between hardware, firmware, and software. At best a new operating system could be re-programmed. However, this is often why new operating systems have difficulty supporting every piece of hardware there is.
What is extensive firmware interface?
Extensive firmware interface is defined as a specification that originates from Intel. It defines the interface between platform firmware and the operating system. It tries to reduce dependence of the OS on the firmware implementation details.
Embedded Operating System?
embeded os works as a firmware and applies the concept of firmaware .
