Which component on a computer stores permanent instructions which cannot be changed?
The ROM BIOS chip stores permanent instructions. ROM means read-only memory. BIOS means basic input/output system, meaning the very basic instructions needed to power up the computer. From there, the operating system loads.
What is the difference between primary and secondary memory?
P.M. memory includes RAM and ROM, which is temporary and permanent both. S.M. memory is just permanent memory which is used for the future. P.M. memory is used for the present work.
How is a memory-resident part of an operating system different from a nonresident part of an system?
Memory resident instructions are instructions that remain in the memory while the computer is running. Nonresident instructions remain on the storage medium until they are needed.
What Consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data information?
Memory
What consists of electronic components that store instructions waiting to be executed by the processor data needed by those instructions and the results of processed data (information).?
Memory
Where are Rom situated in a computer?
ROM (read-only memory) chips are installed on a computer's motherboard. The model of the board usually determines the type of ROM needed to control a computer's boot routine. ROM is often called "nonvolatile memory," meaning that an electrical current is not needed to maintain the prerecorded data instructions on the chip. The instructions cannot be overwritten, and only special equipment can be used to rewrite or erase the data
What are the advantages of memory mapped IO?
Memory mapped IO uses a portion of RAM to handle IO requests. In this manner, instructions the CPU uses for reading and writing memory can also be used for IO, reducing the circuitry needed. This makes the CPU simpler, cheaper and more effecient.
Why a computer needs two kinds of memories?
A rather basic answer is that RAM means Random Access Memory. This memory is volatile, and everything is lost when the computer is closed down.ROM means Read Only Memory. This is stable memory placed there by the manufacturer to keep the instructions needed to begin the booting up process when the computer is switched on.
Why is cache memory needed?
Cache Memory is needed because Hardware implements cache as a block of memory for temporary storage likely to be used again.
Define Read Only memory?
Read Only Memory (ROM) is a type of non-volatile memory where data is permanently written during manufacturing and cannot be easily altered or deleted. ROM is commonly used to store firmware and essential software instructions that are needed to boot up a device or system.
How is a memory-resident part of an operating system different from a nonresident part of an operating system?
A memory resident, which means it remains inmemory while the computer is running, other parts of the operating system are nonresident, meaning these instructions remain on a storage medium until they are needed.
Why temporary memory is required for computer even though permanent is available?
Temporary memory is used to store program and applications that are being used at the time and allows for computing to be much faster. After the program closes the memory is no longer needed. there are two types RAM and Virtual Memory. RAM is a separate card and stands for Random Access Memory. Virtual Memory is space reserved on the Hard drive for the same purpose. By far the most efficient type is RAM as it is much faster than Virtual Memory and doesn't take Hard drive space al though for a modern computer both are needed for efficient performance.
