BIOS refers to (Basic Input Output System) it is responsible for booting of your system while DOS(Disk Operating System) is an operating system that user uses by entering commands in command prompt(to open in windows press start+r).
BIOS is a system software and CMOS is fabrication technology

Well Bios can't ever be alive without rom and rom without bios is useless :D
CMOS is the little battery in the computer's motherboard which keeps the computers internal clock running.
The best method to reset a BIOS password depends on what BIOS the computer has. Common BIOS's include AMI, Award, IBM and Phoenix. Numerous other BIOS's do exist, but these are the most common. Some BIOS's allow you to require a password be entered before the system will boot. Some BIOS's allow you to require a password to be entered before the BIOS setup may be accessed. The general categories of solutions to reset a BIOS password are: Using a Backdoor BIOS Password Resetting the BIOS Password using Software Resetting the BIOS Password using Hardware Vendor Specific Solutions for resetting the BIOS Password
It's not really clear how much a BIOS costs since they're not marketed to end users but are sold to motherboard manufacturers. A BIOS is essentially a part of a motherboard. A BIOS is likely to be removable on a modern motherboard and technically it could be possible to replace a BIOS if it went bad or if for some reason it was to be upgraded, but for BIOS upgrades usually it is sufficient to flash (reprogram) the existing BIOS.

The CMOS contains user-defined settings for the BIOS. The Bios is a program that contains hardware instructions on how to start the computer.
Data stored in CMOS can be altered using a CMOS editor program. CMOS commonly stores the computer's BIOS and its content can be changed using the inbuilt BIOS settings utility.

CMOS Setup
You can press the Delete or F2 key to get into bios and then you can reset the settings or you can reset CMOS. This guide shows you how to reset CMOS - http://www.eteknix.com/how-s/how-reset-cmos-122/
There are three ways to clear the CMOS on a computer. You can access the BIOS menu and reset the BIOS settings, you can use the motherboard jumper or clear it by reseating the CMOS battery.
Assuming you mean "flash the CMOS", when the CMOS settings are so messed up, you cannot access the BIOS.
how can i break bios password without remove cmos battery
The purpose of CMOS RAM is to hold the BIOS program as it is executed by the processor. BIOS is the first program to be loaded when a computer is powered on.
cmos ram might be corrupt. run bios setup and reset bios to default settings. if it occurs again try, flashing bios.
The CPU depends on the BIOS to fetch instructions for processing and then to present it to the user after it is processed, The BIOS also depends on the CPU to process the information it fetches and sends back.
BIOS is the basic CMOS is what BIOS is stored and started
