Primary storage, also known as main memory or internal memory, refers to the storage space in a computer that is directly accessible to the processor. Primary storage is typically used to store data and instructions that are currently being used or processed by the computer.

Secondary storage, also known as external memory, refers to storage space that is not directly accessible to the processor, but is used to store data and instructions for longer periods of time. Secondary storage is typically used to store data that is not currently being used, but that needs to be kept for future reference.

There are several key differences between primary storage and secondary storage:

Speed: Primary storage is generally faster than secondary storage, as it is directly accessible to the processor. This means that the processor can access and retrieve data from primary storage more quickly than it can from secondary storage.

Capacity: Primary storage is typically smaller in capacity than secondary storage. This is because primary storage is used to store data that is currently being used or processed, while secondary storage is used to store data that is not currently being used.

Cost: Primary storage is typically more expensive than secondary storage, as it requires faster and more expensive memory chips.

Volatility: Primary storage is generally volatile, meaning that it is lost when the power is turned off. In contrast, secondary storage is non-volatile, meaning that it retains data even when the power is turned off.

Location: Primary storage is located inside the computer, while secondary storage is typically external to the computer and is connected to the computer through a port or interface.

The distinction among number one and secondary reminiscence is that Primary reminiscence is the primary reminiscence of the device/ laptop wherein the processing information exist and the secondary reminiscence of a device/ laptop is an auxiliary reminiscence that shops the information permanently.

The primary memory of a device or computer is the primary memory in which the processing data are stored, whereas the secondary memory of a device or computer is an auxiliary memory that permanently stores the data.

From a computer point of view,

Primary memory usually refers to Random Access Memory (RAM), while secondary storage refers to devices such as hard disk drives, solid-state drives, removable “USB” drives, CDs, and DVDs.

Primary storage and secondary storage are two types of storage in a computer system, each serving different purposes. Here's how they differ:

Primary Storage:

Primary storage, also known as main memory or internal memory, refers to the computer's immediate access storage.

It is used to store data that is actively being processed or accessed by the computer's CPU (Central Processing Unit).

It provides fast and temporary storage for the computer's operating system, applications, and data.

The primary storage is volatile, meaning its contents are lost when the computer is powered off or restarted.

The two main types of primary storage are:

a) Random Access Memory (RAM): RAM is a type of primary storage that holds data and instructions that the CPU is actively working on. It provides quick access to data and allows for efficient multitasking.

b) Cache Memory: Cache memory is a small, high-speed storage that stores frequently accessed data and instructions to accelerate the CPU's processing speed.

Secondary Storage:

Secondary storage, also known as auxiliary storage or external memory, refers to long-term storage devices in a computer system.

It is used for storing data and programs that are not actively being used by the CPU.

Secondary storage devices offer larger storage capacities compared to primary storage.

The data stored in secondary storage is non-volatile, meaning it remains intact even when the computer is powered off or restarted.

Examples of secondary storage devices include hard disk drives (HDDs), solid-state drives (SSDs), optical discs (CDs, DVDs, Blu-ray), USB flash drives, and external hard drives.

Secondary storage is typically slower than primary storage in terms of data access and retrieval.

In summary, primary storage provides fast and temporary storage for actively used data, while secondary storage offers larger and non-volatile storage for long-term data storage and archiving.

STORAGE:

primary storage refers to the main storage of the computer or main memory which is the random access memory or RAM

Secondary storage, on the other hand, refers to the external storage devices used to store data on a long-term basis.

Access of Primary Vs. Secondary Storage:

Primary storage holds data or applications which can be directly accessed by the processing unit with minimum or no delay

On the contrary, secondary storage is used to store and retrieve data permanently with no delay

Nature of Primary Vs. Secondary Storage

Primary storage is a volatile memory which means data is lost as soon as the device loses power and it cannot be retained. Primary storage is commonly referred to as primary memory such as the RAM

Secondary storage, commonly known as secondary memory, is a non-volatile memory which is able to retain data even if the device loses power

Device used for Primary Vs. Secondary Storage

RAM is the most common primary storage device which also goes by main memory and is used to store data machine code currently in use. Instructions can be retrieved from the RAM whenever required. It provides fast data access with no delay.

Secondary storage refers to external storage devices such as optical media (CDs and DVDs), hard disk drives (HDD), floppy disks, USB flash drives, etc.

Speed of Primary Vs. Secondary Storage

As programs and applications are stored in main memory, primary storage provides fast and efficient access to the CPU.

On the contrary, secondary storage is more of a long-term storage solution with substantial data storage capacity which makes them relatively slower than their primary counterparts.

The difference between a primary storage and a secondary storage is with a primary, it is your main storage. The secondary is where things get stored when your primary is full.

What is secondary memory device?

Secondary memory, also called auxiliary memory or mass storage, consists of devices not directly accessible by the CPU. Hard drives, floppy disks, tapes, and optical disks are widely used for secondary storage. The input and output of these devices is much slower than for the semiconductor devices that provide the computer's primary memory. Although access times (i.e., the time to read or write information) are slow as compared to that of primary memory, secondary memory devices have important features that are unmatched by primary memory. First, most secondary storage devices are capable of containing much more information than is feasible for primary memory (hence the use of the term "mass storage" as a synonym for secondary memory). A second, and essential, feature of secondary memory is that it is non-volatile. This means that data is stored with or without electrical power being supplied to the device, as opposed to RAM, which can retain its data only so long as electrical power is present.
