Is pendrive a primary memory?
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.
What is tertiary storage?
Tertiary storage is cold storage. It is usually updates less frequently than secondary (full dump once a week, incremental dump once a day), and is not constantly online, it at all. In older days, secondary was a second disk-based array, and tertiary was tape and the mountain.
What is storage device?
Storage devices hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. There are two types of storage device: secondary storage device and primary storage device. Primary Storage -.
Why is a removable media unit removed from a drive?
The removable media unit can be removed from the drives so that the storage capacity can be expanded with more media units. When data on a media are accessed, the media unit is accessed from their normal location. One of the storage drives on the computer system is chosen.
What is ROM storage?
A ROM stores such instructions that are required to start a computer. Secondary storage device. A secondary storage device has a larger storage capacity and can store data permanently. The device can be both external and internal to a computer and includes; compact disk, USB drive, hard disk, etc.
What is RAM memory?
RAM (Random Access Memory) Random access memory which is also known as RAM is generally known as a main memory of the computer system. It is called temporary memory or cache memory. The information stored in this type of memory is lost when the power supply to the PC or laptop is switched off.
What is tertiary storage?
The main objective of the tertiary storage level is to provide huge storage capacity at low cost . Several types of storage devices are available to be used at the tertiary storage level in Hierarchical Storage Systems (HSS). They include: • Magnetic tapes • Optical disks • Optical tapes These storage devices are composed of fixed storage drives and removable media units. The storage drives are fixed to the computer system. The removable media unit can be removed from the drives so that the storage capacity can be expanded with more media units. When data on a media are accessed, the media unit is accessed from their normal location. One of the storage drives on the computer system is chosen. If there is a media unit in the storage drive, the old media unit is unloaded and ejected. The new media unit is then loaded to the drive. Each type of storage drive may handle the storage drives and media units differently. The magnetic tapes are described below in the next section. Then, the optical tapes are presented. Afterwards, the optical disks are briefly described before this chapter is summarized.

What is storage device?
A storage device is one of the basic and necessary components/elements of a computer (desktop, laptop, notebook or tablet). Except for hardware firmware, it contains almost all data and applications on a computer. Related article: Different Types of Hard Drives: Which One Should You Choose.
How many types of storage devices are there?
After learning the hierarchy of storage, it is reasonable to say that there are 4 types of computer storage devices: primary, secondary, tertiary and offline storage devices. As for the common secondary storage devices, they can be further divided into internal and external storage devices of computer according to their location, inside or outside of computers or servers. And, external storage devices are also called portable computer storage devices.
What is semiconductor memory?
Semiconductor memory makes use of semiconductor-based integrated circuit (IC) chipsets to save data and both volatile and non-volatile forms of semiconductor memory exist . In modern times, primary storage nearly all consists of dynamic volatile semiconductor RAM, especially DRAM.
Why do computers use storage hierarchy?
Practically, nearly all computers make use of a storage hierarchy to arrange computer storage. Storage hierarchy puts fast, small yet expensive computer storage devices close to the CPU (Central Processing Unit), while slow, large yet cheap ones far away. The fast storage media adopting the volatile technologies, which lose data when power is off, ...
What is the term for the fast storage media?
The fast storage media adopting the volatile technologies, which lose data when power is off, are referred to as “memory”. While the slow storage options relying on the non-volatile (persistent) technology, which retains data when there is no electricity, are referred to as “storage”.
What is external storage?
And, external storage devices are also called portable computer storage devices. Based on the material of the pc storage devices, there are semiconductor storage devices, magnetic storage devices and optical storage devices:
What is offline storage?
Offline storage is a kind of computer digital data storage on a media that isn’t controlled by the CPU. The media is usually recorded as a secondary or tertiary storage device and be physically removed or disconnected from its attached computer. To access it again, you must insert or connect it to your computer.
Primary Storage Device
Primary storage devices are constructed with integrated circuits (IC) or semiconductor components.
Secondary Storage Device
Secondary storage devices are also known as “Auxiliary Memory“, or “External Memory“. Secondary storage devices are volatile in nature; it means that data does not discard while getting to turn-off power, in which all data store for long time.
Tertiary Storage Device
Tertiary storage offers the third phase of storage medium. It enables with robotic mechanism that will help to insert and remove massive storage media into storage device as per the system’s need.
