Which type of memory contains device-specific information and handles a computer's basic functions when it is powered on?
Random-access memory (RAM) is used to store both program instructions and data. Typically both need to be present in memory in order for a program to execute. Often multiple programs will want access to memory frequently demanding more memory than the computer has available.
Tue May 29 2007 14:30:00 GMT-0400 (Eastern Daylight Time) · In computer programming a handle is an abstract reference to a resource that is used when application software references blocks of memory or objects that are managed by another system like a database or an operating system.. A resource handle can be an opaque identifier in which case it is often an integer number (often an array index in an array or "table" that is used to manage that type ...

This requires ROM integrated circuits to be physically replaced or EPROM or flash memory to be reprogrammed through a special procedure. Firmware such as the BIOS of a personal computer may contain only elementary basic functions of a device and may only provide services to higher-level software. Firmware such as the program of an embedded system may be the only program that will …
When the computer is powered on it typically does not have an operating system or its loader in random-access memory (RAM). The computer first executes a relatively small program stored in read-only memory (ROM) along with a small amount of needed data to access the nonvolatile device or devices from which the operating system programs and data can be loaded into RAM.
Later computers including all IBM-compatibles with 80286 CPUs had a battery-backed nonvolatile BIOS memory (CMOS RAM chip) that held BIOS settings. These settings such as video-adapter type ...
