What is the secondary memory in psychology?
Secondary memory, or long-term memory, holds unlimited information from the past, but retrieval from secondary memory is dependent on search cues that may not be efficient, making the likelihood of recalling items from secondary memory lower than recalling items in primary memory.
What is secondary memory in the human brain?
2 Secondary Memory Secondary memory is like long-term memory in the human brain. Once the computer needs to keep the data it processes, it goes to a storage device where it can be recalled later. Secondary memory holds information that might not be in use but can be accessed at any time.
Is an example of secondary memory?
Secondary memory is known as a Backup memory or Additional memory or Auxiliary memory. Hard Drive, SSD, Flash, Optical Drive,USD Drive are some examples of secondary memories in computer.
What is the difference between main and secondary memory?
Primary memory is the main memory of the computer which can be directly accessed by the central processing unit, whereas secondary memory refers to the external storage device which can be used to store data or information permanently. …
What are the different types of secondary memory?
There are three main types of secondary storage in a computer system: solid state storage devices, such as USB memory sticks. optical storage devices, such as CD, DVD and Blu-ray discs. magnetic storage devices, such as hard disk drives.
What is primary memory psychology?
primary memory (PM) memory that retains a few items for only several seconds, in contrast to secondary memory. The term was used in dual-store models of memory before being replaced by short-term memory. [ introduced by William James ]
Which of the following is true about main and secondary memory?
Which of the following are true about main and secondary memory? Main memory is short term memory used by the CPU in processing commands, secondary memory is more permanent and used for storage.
What do you mean by secondary memory give examples?
Secondary memory refers to storage devices, such as hard drives and solid state drives. It may also refer to removable storage media, such as USB flash drives, CDs, and DVDs. For example, a computer may have a one terabyte hard drive, but only 16 gigabytes of RAM.

- It is known as the backup memory.
- It is a non-volatile memory.
- Data is permanently stored even if power is switched off.
- It is used for storage of data in a computer.
- Computer may run without the secondary memory.

What are the differences between primary and secondary memory?
The key difference between primary and secondary memory is that primary memory can be directly accessed by the CPU whereas, the CPU can not directly access the secondary memory. The primary memory of the computer is also known as the main memory of the computer. However, secondary memory is known as auxiliary memory.
What are the types of secondary memory?
One of the most common types of secondary memory is the hard drive on a computer. This drive is accessed by the CPU through one of several different indirect methods and data remains on the drive even without a power supply. Other disc drives, such as those used with CDs and DVDs, are also types of secondary memory utilized for other purposes.
What is a secondary memory of a computer?
Secondary memory is a type of computer memory that is not directly accessed by the central processing unit (CPU) of a computer and is usually available as non-volatile memory. One of the most common forms of this memory is the hard drive of a computer, which is used to store the operating system (OS) and other programs.
What do you mean by primary memory and secondary memory?
Summary Computer memory is the storage space where data is to be processed, and instructions needed for processing are stored Two types of memories are 1) Primary Memory, 2)Secondary Memory Primary memory is the main memory of the computer system. All secondary storage devices which are capable of storing high volume data is referred to as secondary memory
