What else can I help you with?
Main memory is used to store data permanently.?
No. It is usually used to help run the programs your are running at that moment and store other associated data.
What the functions of the main memory?
to store data
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.
Is cache memory necessary?
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.
What is difference between RAM and harddisk?
RAM means Random Access Memory. It store data temporaly. It called primary storing device. The two main forms of modern RAM are static RAM (SRAM) and dynamic RAM. Harddisk is the primary storing device within the computer. It can store data permanently (until you delete the data). It can retain data even after the computer itself "dies". Therefore, one harddisk can be switched to a different computer of similar size. An external harddisk can store huge amounts of data within a desktop unit. It can store data permanently (until you delete the data).
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
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.
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
What are the functions of DRAM memory?
Main memory is the storage that is directly available to the CPU of a computer and is made3 up of RAM and ROM. RAM's (Random Access Memory) purpose is to hold the data and instructions temporarily which the CPU will process. ROM's (Read Only Memory) function is to hold data necessary for starting up the computer permanently , whose contents cannot be changed by the user.
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.

Computer store data in how many main places?
3 one is a memory slot, another is a flashdrive, another is a floppy disk.
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
