What are the differences between main and secondary memory?

Is newly created process is in main memory or in secondary memory?

A newly created process is in main memory.

What program in an OS coordinates the memories by tracking which one is available which is to be allocated or deallocated and how to swap between the main memory and secondary memories?

The memory manager is the program responsible for managing memory allocation and deallocation in an operating system. It keeps track of which memory is available and allocates it to processes based on their needs. It also handles swapping data between main memory and secondary storage when the system runs low on physical memory.

Distinguish between primary and secondary memory?

Computer memory is categorized into primary and secondary memory. While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.

How does virtual memory differ from main memory and secondary memory?

The computer uses microchips for primary and secondary memory. Virtual memory uses a portion of the computers hard drive. The former have faster access times than the latter.

How main memory and secondary memory are interlink?

Main memory (RAM) and secondary memory (like hard drives or SSDs) are interlinked in that they work together to store and manage data for computing tasks. Main memory is used for temporarily holding data that is actively in use by the CPU, allowing for quick access and processing. In contrast, secondary memory provides long-term data storage, retaining information even when the computer is powered off. Data is transferred between these two types of memory, with the operating system managing this flow to optimize performance and ensure that necessary data is readily available in main memory when needed.

Secondary storage and main memory are both types of memory in a computer. What are some differences between them And why does a computer need both of them to work Give an example of each?

Secondary storage and main memory are both types of memory used in a computer, but they differ in terms of their speed, capacity, cost, and volatility. Main memory, also known as primary memory or RAM (Random Access Memory), is a fast, volatile, and temporary form of memory that the CPU (Central Processing Unit) uses to store data and instructions that it is currently processing. Main memory is directly accessible by the CPU and has faster read/write speeds compared to secondary storage. However, main memory is volatile, which means that it loses its contents when the power is turned off or in case of a system failure. An example of main memory is DDR4 RAM. Secondary storage, also known as external memory or non-volatile memory, is a slower, larger, and more permanent form of memory that the computer uses to store data and programs that are not currently in use. Secondary storage is not directly accessible by the CPU and has slower read/write speeds compared to main memory. However, secondary storage is non-volatile, which means that it retains its contents even when the power is turned off. An example of secondary storage is a hard disk drive (HDD) or solid-state drive (SSD). A computer needs both main memory and secondary storage to work efficiently. Main memory provides fast access to data and instructions that the CPU is currently processing, while secondary storage provides a larger and more permanent storage space for data and programs that are not currently in use. Without main memory, the CPU would have to constantly read and write from secondary storage, which would significantly slow down the system's performance. Without secondary storage, the computer would not be able to store large amounts of data and programs permanently. An example of main memory usage is when a user opens a word processing program, and the program's instructions and data are loaded into main memory for processing. An example of secondary storage usage is when a user saves a document to their hard disk drive, where it is stored permanently until the user deletes it. Regenerate response

What are the differences between main memory and register?

Registers are very small but are extremely fast. RAM is much larger and smaller memory that applications use as a scratch space.

What are the main differences between inexpensive RAM and memory upgrades and the top of the line?

There are only types of memory technology.The most expensive types are the most recent technologies.

What are the main differences between primary and secondary industries?

well the primary industury grows and take care of the product then sells it while the secondary industury kills watever and makes a bigger profit out of it.

What is the use of virtual memory?

Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.

What is main memory in computer architecture?

main memory is RAM.The words Memory,Buffer,Cache are all refers Ram. Which is Nearly 11,000 times faster than secondary memory (Hard Disk) in Random Access.

What is the difference between main and auxiliary memory?

The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing.
