Distinguish between primary storage and secondary storage?
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.
What is a generic term used to collectively describe hard disks CDs and flash drives?
storage, non-volatile storage, persistent storage, mass storage, non-volatile memory. There are lots of ways to say it. I would say "storage media" myself.
Why a computer system needs both primary and secondary storage?
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.
The hard disk drive is what kind of storage device?
it is the primary storage unit of a computer
Which device holds data and instructions when it is not inn use?
Secondary Storage
Is primary storage volatile?
Primary storage is volatile; meaning it cannot retain data values indefinitely. In other words, when power is turned off, all contents are lost. Secondary storage is non-volatile.
What it as your computer's primary means of storage?
The primary means of storage of a computer is the RAM memory which is a volatile memory.
Is HDD a volatile or a non-volatile storage device?
HDD (Hard Disk Drive) is Non Volatile storage device (permanent). It is also considered as Secondary storage device. Secondary storage devices are always non volatile. Primary storage devices like Ram are volatile (temporary).
Is HDD a volatile or non volatile storage device?
HDD (Hard Disk Drive) is Non Volatile storage device (permanent). It is also considered as Secondary storage device. Secondary storage devices are always non volatile. Primary storage devices like Ram are volatile (temporary).
Is a hdd is volatile or non volatile device?
HDD (Hard Disk Drive) is Non Volatile storage device (permanent). It is also considered as Secondary storage device. Secondary storage devices are always non volatile. Primary storage devices like Ram are volatile (temporary).
Differences between secondary storage and primary storage?
Primary storages are volatile. An Example of primary storage : RAM whereas, Secondary storages are permanent. An Example of secondary storage : ROM
Primary storage devices names?
RAM is a primary storage medium, but it is volatile. Cache memories storage frequently accessible data.
Is DRAM a primary storage?
No, DRAM (Dynamic Random-Access Memory) is not considered primary storage; it is a type of volatile memory used as main memory in computers. While it stores data temporarily for quick access by the CPU, primary storage typically refers to non-volatile storage solutions like SSDs or HDDs that retain data even when powered off. DRAM is essential for system performance, but it is not a permanent storage solution.
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.
Is hdd a volatile or a non volatile storage devices?
A hard drive is non-volatile storage, since it retains all of the data written to it even when it is no longer supplied with power. In general, a computer's internal operating memory is volatile, while its data storage is non-volatile.
Are hard drives considered volatile storage devices?
No, they are permanent storage devices, only RAM is volatile storage device.
What is difference between primary storage secondary storage and offline storage?
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.
