It saves the passwords given in a particular computer.
It also controls how the computer responds when first switched on.
It sets the clock, determines which drive is looked at first, turns caps lock on/off, allows or denys external graphics card to be used and controls how memory is allocated.
It all depends on which manufacturer made your motherboard, some allow more functions than others.
What else can I help you with?
Can a ttl chip drive a cmos chip without modification?
A TTL chip can drive a CMOS chip without modification if the CMOS chip is designed to do so. Many large scale CMOS chips, such as microprocessors, have LS (or equivalent) TTL IO pins, so you can drive them directly. In the absence of that, you can use a pull up resistor, but you need to look carefully at fan-in, fan-out, rise time, fall time, and power requirements, in order to assure proper operation. It is best to use chips that are designed for the application, such as TTL to CMOS buffers.
Will system boot up normally to operating system level if CMOS battery is dead?
CMOS holds many of the boot parameters, such as what type and size of hard disk, the type and speed of the processor and other critical information. Many times the computer can still boot with a dead CMOS battery, but the information will not be available and will affect the process. Replace the battery then run through the setup procedure to save the values.
Which hardware component contains instructions that are used during the booting of the computer?
That would be firmware such as the ROM BIOS or the EFI. That is Read-Only Memory or a modern variation. BIOS stands for Basic Input/Output System, while the newer technology EFI stands for Extensible Firmware Interface.ROM doesn't require in any batteries. Even EPROM, EEPROM, and NVRAM don't use batteries. What did use batteries was the CMOS memory which may be separate from the ROM, though it could be in the same chip or part of the real-time clock chip. That was not Read-Only Memory, since you would use the CMOS setup to change it. If it can't be changed, no battery would be required. When that battery dies, you only use the hardware settings, not the code that brings up the computer.
Can a CMOS gate adequately drive a common LED?
You will have to check the datasheets for both the CMOS gate and the LED, then if the CMOS gate's rated output current is enough to light the LED you will need to do a little arithmetic using Ohm's law to calculate the resistor to put in series with the LED to limit current and avoid damaging the parts.
What are the applications of CMOS?
cmos technology is used in low power applications in vlsi and also used in image processing.cmos inverter has many applications like oscillator,amplifier and also used in analog transmission,digital applications etc.,
Do all systems use the same setup to enter cmos setup?
No, not all systems use the same method to enter CMOS setup. Some systems allow access to CMOS setup by pressing DEL during start up and others by pressing F2.
Can you How disable Block mode?
Use CMOS setup.
Do all systems use the same method to enter CMOS setup?
No, not all systems use the same method to enter CMOS setup. Some systems allow access to CMOS setup by pressing DEL during start up and others by pressing F2.
Where is cmos setup stored?
Cmos ram.
What enables you to access and modify CMOS data?
To access and modify the CMOS data, you would need a CMOS setup utility. Originally, in the IBM AT and a few close clones, it required a separate utility on a diskette. However, manufacturers soon added this utility the the ROM BIOS. So even today, all you have to do is enter CMOS setup is to press a certain day upon booting the system. Delete, F1, and F2 are some of the common keys to use for entering the CMOS setup utility.
What is the name of the Bios program that edits values in CMOS RAM?
CMOS Setup
Ports on the motherboard can be disabled or enabled in?
CMOS setup
When was the CMOS made for the computer?
If you mean the CMOS setup, then it was likely made around 1984. That was the year that IBM released the AT computer. That was the first to make use of CMOS settings. If you mean CMOS-based logic chips, they have been around since at least the the mid 1970's.
What program allows the alteration of CMOS settings?
CMOS settings are altered by the BIOS program while in setup mode.
Write on system board?
cmos setup removed password
How can you change the contents of the cmos ram setup chip?
fake
What is advantage of CMOS setup?
CMOS is a type of technology for constructing integrated circuits. One advantage of this setup is less waste heat compared to NMOS logic or transistor-transistor logic.
