What is the storage device with the example? What are the ten types?
Hello friends, welcome back again . Today we will discuss what is a storage device ( what is a storage device ) and give complete information about the types of storage devices. If you want to know or not about primary memory and secondary memory, these posts are for you.
A storage device is a part of a device connected to any computer or electronic device that stores data or information, in which many types of data such as programs, documents, images, video, audio, etc. can be stored. It acts as memory and is also called storage media or digital storage .
It is used to store data digitally , and this data can be permanent or temporary . Whenever we need the data saved in it , we can access it at any time with the help of this storage device
So let us now see what is the storage device and its types (primary memory and secondary memory) which will be discussed in detail.
What is a storage device (what is a storage device)
A storage device is a part of computers that is used to store, transfer, extract data files and exchange data for any data and application. It works to keep any data or information permanently and temporarily.
There are many different types of storage devices and each has its own distinct advantages and disadvantages. Known as the storage device as well as the media storage or storage medium . For example - a standard computer has many other storage devices including RAM, ROM, hard disk, and cache.
Types of storage devices
There are two types of storage devices in a computer.
Primary storage device
The primary storage device is used to hold data temporarily. It is rather small in size. Because it is on the inside of the computer. These include RAM and cache memory . It is also called the main memory of the computer. This memory stores the instructions, the operating system, and the data required to operate the computer. Primary memory, also called temporary memory or cache.
There are two basic storage devices-
RAM (Random Access Memory)
It performs both read and write operations on memory . It stores data temporarily. If the power goes out while accessing memory in the system, the data in this memory will be lost permanently, so RAM is volatile memory. RAM is divided into the following types:
- Dynamic random access memory (DRAM)
- Static random access memory (SRAM)
- rambus dynamic ram (RDRAM)
ROM (Read Only Memory)
ROM stores such information that it is read only memory which makes it difficult to modify the data. ROM is also a type of persistent storage, which means that even after a power failure, it stores information and does not allow data to be lost. Here are the names of some of the following ROM types-
- PROM (programmable ROM)
- EPROM (Erasable and Programmable Read-Only Memory)
- EEPROM (Electrically Erasable Programmable ROM)
- EEPROM (Electrically Erasable Programmable ROM)
temporary memory
Cache memory is a small-sized volatile computer memory that provides high-speed data access to the computer's microprocessors and stores frequently used computer programs, applications, and data. It is more expensive than RAM and disk memory.
It is used to reduce the average time it takes to access data from main memory. It is much faster than the speed of main memory, also called CPU memory because it is very close to the CPU chip. Therefore, the CPU accesses the data stored in the cache faster.
Secondary storage devices
The secondary storage device has the ability to store the maximum amount of data and at the same time keep any data stored permanently. This storage device is on the inside or outside of the computer. There are such kinds of devices like hard drives , hard disk and USB flash devices etc.
Generally, secondary storage devices have the ability to store data from megabytes to petabytes. These devices store almost all types of data, programs, and applications on a computer, including the operating system, device drivers, applications, and general user data.
Most secondary storage devices are used for a variety of tasks, such as backing up data for future or disaster recovery, storing long-term used data, or storing less-used junk data on an inexpensive storage device. the device. Below are the names of some secondary storage devices-
- SD cards
- tape drives
- DVD drives
- CD drives
- Blu-ray drives
- Floppy disk
- USB input
- cloud storage
- Solid State Drives (Solid State Drives)
- hard drives (hard disk drives)
Example of secondary storage devices
hard disk drive
A hard disk drive is a non-volatile magnetic storage device capable of storing large amounts of data. This internal hard drive is the computer's main storage device. It is found installed in almost all laptops and desktops. It stores running system programs, software, and user documents , such as images , text files , videos , and audio .
It is used to permanently store and retrieve data on a computer , to be a portable backup and store. Usually, these boards are attached to the motherboard on the inside of the computer. In addition to the interior of the computer, it is also a removable external hard drive that connects the external hard drive to the device via a USB connection.
Floppy disk
Floppy disk is also known as FD for short. A floppy disk is a storage medium that uses magnetic storage technology to store data . The floppy disk lasted from the 1970s to the beginning of the 21st century, and at that time was a popular storage tool for computers. Initially, floppy disks were 8 inches (203 mm) in size, but were later changed to 5-inch (133 mm) drives, and eventually the 3-inch (90 mm) version.
Solid-state disks
The full form of an SSD is a solid state drive. It is also a storage device technology for storing data such as hard disks. This is the latest storage device technology used in a computer. It is used in devices such as laptops, notebooks, and desktop computers instead of traditional drives.
SSD does not have any moving parts like HDD, so it has very low power consumption compared to HDD and provides better performance. The long life of this storage device is much more than that of a hard drive. The SSD reads/writes data at a very high speed , which also makes the access time less due to its high speed. These are more expensive storage devices than hard drives.
optical storage device
The complete CD and DVD format are versatile CD and DVD discs respectively. CD and DVD are the most common and popular optical storage media. This disk is later used to extract or retrieve stored data. Optical storage CDs and DVDs are used to store programs, backup files, and store music and videos.
It is a technology that uses lasers and light to read/write data . A standard CD typically stores 700MB of data for 80 minutes, but DVDs are capable of storing much more data than CDs. DVD discs come in a variety of storage capacities starting from 4.7 GB up to a maximum of 17.08 GB.
USB flash drive
It is a portable secondary storage device that connects to a computer via a USB port. Also known as a data stick, pen drive, kitchen drive, thumb drive, and USB flash drive. It is the easiest way to transfer data from one computer to another computer to store large amounts of data. Its storage capacity can range from 2GB to 1TB.
The USB flash drive has no moving parts, instead it has an integrated circuit in which an integrated memory stick is installed to store data.
Examples of a computer storage device
magnetic storage devices
Nowadays, magnetic storage is one of the most common types of storage used with computers. It is often found on large hard drives or hybrid hard drives.
- Floppy disk
- Solid State Drives (Solid State Drives)
- hard drives (hard disk drives)

cloud storage
Nowadays, storing data online and on cloud storage is becoming more and more popular because in this digital age people need to access their data information from more than one device from anywhere.
- cloud storage
- media network
paper storage
In the early days of computers, no technology for storing information was invented, so one had to rely on paper to store information. Nowadays, paper storage is rarely used or found anywhere.
- Omani Rial
- perforated card
computer memory modules
The computer understands only machine language, since only 0 and 1 store data in a two-digit computer memory. It is called Bits or Binary Digit with two digits.
The machine language of the computer is written in binary code and begins with 8 bits or 8 digits (eg - 10101001). This set of 8 bits is called 1 byte.
| Noun | measuring |
| 1 bit | single digit 0 or 1 |
| 1 nibble | 4 bit |
| 1 byte | 8 bit |
| 1 kilobyte (KB) | 1024 bytes |
| 1 megabyte (MB) | 1024 KB |
