Unlike primary storage; secondary storage is not directly accessed by the CPU. Examples of secondary storage are hard drives, CD/DVD drives, flash, etc. Anything that can store data without losing it upon power down (non-volatile storage) is considered secondary storage.
I believe you can tell why it's a necessary component of a personal computer. Without it we would have no place to store our data.
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 greatest nonvolatile storage capacity in the computer system is usually found in secondary storage and mostly on the hard disk. RAM on the other hand represents the greatest volatile storage capacity on a computer.
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.
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 mainframe computer 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.)
An operating system in storage and loads it into memory.
Primary storage is usually the drive where the operating system is and the secondary storage is a additional drive for space. Usually, Windows names it's primary drive as C:\ and all it's following as other letters.
Primary storage, also known as main memory or RAM, is the computer's fast and temporary storage used for actively running programs and data that are in use. It is volatile, meaning it loses its data when the power is turned off. In contrast, secondary storage, such as hard drives and SSDs, provides long-term data retention and is non-volatile, retaining information even when the power is off. While primary storage is faster, secondary storage offers greater capacity and is essential for storing files, applications, and the operating system.
Primary storage refers to the main memory of a computer, such as RAM, which is fast but temporary and volatile, meaning it loses data when power is off. Secondary storage, like hard drives and SSDs, is non-volatile and provides long-term data storage, retaining information even without power. Offline storage refers to any storage that is not directly accessible by the computer's operating system, such as external hard drives, USB drives, or magnetic tapes, which can be disconnected and used for backup or transfer purposes. In summary, primary storage is fast and temporary, secondary storage is slower but permanent, and offline storage is external and not directly connected to the system.

It is important to know how many system words will fit in a primary storage device on a computer so you know how big of a storage unit you have. The more system words that will fit in a primary storage device, the more memory you have on your computer.
Memory of computer system is the part of the computer's hardware that allows it to store information. It is classified into primary/main memory (RAM and ROM) and secondary storage (hard drives, CD drives etc.).
Primary storage is usually the drive where the operating system is and the secondary storage is a additional drive for space. Usually, Windows names it's primary drive as C:\ and all it's following as other letters.
primary and secondary storage may also refer specifically to the components inside the computer. In this case, primary storage typically refers to random access memory (RAM), while secondary storage refers to the computer's internal hard drive.
The greatest nonvolatile storage capacity in the computer system is usually found in secondary storage and mostly on the hard disk. RAM on the other hand represents the greatest volatile storage capacity on a computer.
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.
Auxiliary storage, also known as secondary storage, refers to external devices used to store data that cannot be directly accessed by the CPU. Examples include hard drives, solid state drives, USB flash drives, and optical discs. It provides additional storage capacity to complement the primary storage (RAM) in a computer system.
Cache Main Memory Secondary storage Each storage provides a different speed and amount of storage which is used by the CPU for processing instructions and data.
