it is the ROM . The ROM has firmware which controls the booting up of the computer during start up. The booting software, known as BIOS (Basic Input Output System) give instructions to the POST (Power On Self-Test) which then runs tests to on the computer to make sure that all the devices are well connected to the computer. Sometimes this process is so fast that when observed, it appears as if there is are no tests being run by the POST process.
Cmos chip, it's a chip that keep the boot order in memory , it has a battery on the mother broad, about the size of a dime, when it dies computer want boot
I hold the start up instructions that perpare a computer
It's a mixture of things. BIOS, CMOS, Operating system.
No - it simply holds a list of which programs to start running on 'power-up' - and the order they need to be run. Each system program starts according to a set procedure, and ends with the graphic interfaces that allows the user to log-on.
Kind of - It tells the computer to start up the initial files to get the computer 'up and running'. These are files such as driver programs for the display, keyboard, mouse, screen, printer etc, along with disk controllers, operating system and internet access programs.
what do I press to start a scan on my APPLE computer
Probably because the computer settings are that way, but it could be automatic detection. That happened to me when I traveled to Israel once. Suddenly I was trying to set my browser back to English because the default there is different. If you go back into your computer settings and tell it where you are, that should solve the problem.
The chip which holds software that is used to start the computer is the BIOS. The type of chip may be ROM, EEPROM, or NVRAM.
ram
RAM is used for storing the start-up instructions on the computer. This serves as the memory of the computer which will retrieve such instructions.
Because - the computer needs a specific set of instructions to start -up. The instructions held in ROM initialise the hardware and instruct the computer to load the operating system (and where to find it on the hard-drive).
RAM
no
It is Read Only Memory(ROM) BIOS, basic input/output system, is the system that first runs when a computer is powered on. The software is contained on a ROM chip on the mothrboard and is responsible for executing the boot sequence for different peripherals and the operating system
Yes ROM is the memory that holds everything that tells your computer how to actually start up.
---ROM--- The full of ROM is read only memory. It is nonvolatile. Nonvolatile chips always hold the same data. It holds instructions that run the computer when the power is first turned on. On ROM contains a set of start-up instructions, which ensures that the rest of memory is functioning properly. callltb@yahoo.com
Basic Input Output System (BIOS)
It's a mixture of things. BIOS, CMOS, Operating system.
On start up the computer fetches information from BIOS. BIOS is a ROM. After that the computer loads OS from Hard disk into the RAM.
