Memory can be categorized in different ways by technology or properties: primary access by the CPU or secondary (indirect) access by the CPU. This distinction is primarily based on the speed of access to the memory. volatile or non-volatile is a distinction based on technology (magnetic vs. electrical, etc.). Volatile memory requires power to maintain its stored information. Read-only memory, or read-write is a distinction based on properties of the memory. Read only memory, or "ROM", is not modifiable.

Is virtual memory kept in secondary storage?
Yes, virtual memory uses a combination of both primary (RAM) and secondary (disk storage) memory. When the RAM is full, data is temporarily transferred to the hard drive to free up space for new operations, which is why virtual memory is sometimes referred to as "paging file" or "swap file."
Describe the main types of primary and secondary storage?
Computer data storage, or memory, is the means through which the computer records and accesses digital data. The two types of storage are primary and secondary. Primary storage includes RAM and process registers, and secondary storage is the hard disk and flash memory.
Definition of primary memory?
Primary storage, also known as main storage or memory, is the main area in a computer in which data is stored for quick access by the computer's processor. On today's smaller computers, especially personal computers and workstations, the term random access memory (RAM) - or just memory - is used instead of primary or main storage, and the hard disk, diskette, CD, and DVD collectively describe secondary storage or auxiliary storage.The terms main storage and auxiliary storageoriginated in the days of the mainframecomputer to distinguish the more immediately accessible data storage from storage that required input/output operations. An earlier term for main storage was core in the days when the main data storage contained ferrite cores.2) Primary storage is sometimes used to mean storage for data that is in active use in contrast to storage that is used for backup purposes. In this usage, primary storage is mainly the secondary storage referred to in meaning 1. (It should be noted that, although these two meanings conflict, the appropriate meaning is usually apparent from the context.)RELATED GLOSSARY TERMS: hard disk, magnetoresistive head technology, yottabyte, serverless backup, byte, partition, InfiniBand, failover, RAMAC (random access method of accounting and control), Fibre Channel
What part of the brain is like a switching station between short-term and long-term memory?
The hippocampus is the part of the brain that acts as a switching station between short-term and long-term memory. It processes and consolidates information from short-term memory and transfers it to long-term memory for storage and retrieval.
What are the similarities between the working model of memory and the multi store model?
Both the working model of memory and the multi-store model involve the concept of separate memory systems for different types of information. They both propose that information is processed through different stages before being stored or forgotten. Additionally, both models emphasize the role of rehearsal in transferring information between memory stores.
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.
Who originally distinguished between primary memory and secondary memory?
William James
What is meant by secondary computer memory?
Usually the hard drives are considered secondary. The RAM (Random Access Memory) is the primary memory.
What is the difference between primary key and secondary key?
There is two difference between them. 1. The not null constraint is by default added to primary key, it means, primary key attribute cannot accept null values, whereas, the attribute declared as unique can accept null values. It is the major difference between the two. 2. Secondly, we can have only one primary key in a relation, whereas, multiple attributes can be declared unique at the same time.
IS the Internal memory only primary memory or both primary or secondary memory?
Intenal memory is only primary memory. The term secondary memory is used for External storage like hard disk etc.
Can you use secondary memory in place of primary memory?
No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.
What does the primary memory and secondary memory consists of?
primary memory consist of RAMsecondary memory consist of ROM
What are the disadvantage of primary storage?
Well for mac you can only back up your data when you have a secondary storage hard drive, for windows it gives you more space to download and to use it, basic
How do you change secondary memory to primary?
You have to keep on remebering the memory
What is different between primary memory and secondary memory?
Primary Memory is connected with the motherboard. Examples of primary memory are RAM, ROM, PROM, etc. it works very fast. Secondary Memory are those which are connected to the computer from outside. Examples of secondary memory are floppy disk, cd's, DVDs, etc.
What is the resistance for the primary and secondary windings for a 75 dodge D-100?
If my memory serves me well its less than 2.0 ohms for the primary and between 10,000 -11,000 ohms for the secondary, Mike
Is RAM is a primary memory or secondary memory?
its primary or main memory. all the programs(active or programs currently running on the processor) including operating system reside in RAM .
