Types of computer storage media

definition of computer

 It is a machine or device designed to carry out orders, operations, and calculations based on the instructions provided by people, programs or devices and provides a number of appropriate solutions based on the inputs, and it is a device that performs a series of mathematical or logical operations automatically through programming and computers that are constantly evolving, It can monitor and execute large groups of operations, known as programs that allow the computer to perform a wide range of tasks, and expresses the entire computer in all its parts, including programs, hardware, different types of storage media for the computer, and the system Gail is a computer system, and computers are used as a system for controlling devices and factories that include devices such as microwaves and factory devices, such as robots.

Define storage media for a computer

 The types of storage media for a computer are an integral part of the computer, so you must know what the computer’s storage media are and their types, as it is the main component of computers and is used to store data, a technology that consists of computer components that are used to keep digital data through the central processing unit that It performs complex mathematical operations that help to store data quickly and consists of two main components: the control unit that controls the flow of data between the CPU and memory, and the arithmetic unit and is responsible for mathematical and logical operations You get the data.

 The storage device or Hard Disk is an essential component of the computer that is used to work on storing and extracting data. Types of storage media are available in many specifications and multiple types and are chosen according to the specifications of other parts inside the computer, and the computer must have one storage device At least, volumes can be increased depending on the work the computer user performs, and data can be stored on the device permanently or temporarily in addition to that it can be as a storage device inside the computer or outside the computer external or as a server Data storage in large enterprises, and there are different types of storage media for the computer, which is divided into two main types of basic storage devices and secondary storage.

Storage media functions

 After knowing the types of storage media for a computer, it is necessary to know its functions, as data storage is one of the most important functions of the storage media, a technique that computer components and recording media share to preserve digital data through the CPU, which processes all data through mathematical and logical operations that It consists of two main parts: the console and the arithmetic logic unit, the console that controls the flow of data between the CPU and memory, the arithmetic unit performs mathematical and logical operations on data, and therefore the more memory The computer including the CPU will be able to process data and perform calculations faster and thus store data.

Computer storage media properties

 Distinguishing between storage technologies can be distinguished by some basic characteristics, such as data volatility, changeability, accessibility, and manageability, and the most important characteristics of storage media for a computer are the following:

•  A distinction is made between the types of storage media for a computer through volatilization, where the non-volatile memory holds the stored information, unlike the volatile memory, it requires constant energy to maintain the stored information.
• Writing over information using storage and reading devices is permitted for storage.
• Storage capability through reading and writing multiple times using CD-RW and SSD media.
• One-time writing capability with programmable semiconductor read-only memory and CD-R.
• Ability to access storage locations at approximately the same time.
• Sequential access, where access to information depends on a specific piece of information.
• Information is accessed by specifying it using the digital memory address location.
• Files are identified with specific readable names that storage media use through file systems.
• The ability to access information using the contents stored in it.
• The amount of information that computer storage media types can store is measured in bits, bytes, or megabytes.
• Storage media reduces energy use by about 90%.
• Most types of computer storage media are encrypted in files and folders.
• Storage media capacity is measured by dividing it into different units, such as length, area, or size.
• The unit of measurement used in nanosecond storage for primary storage, and in secondary storage milliseconds are used, while the second is used in high storage media.
• Storage media productivity is measured in megabytes per second.

Types of computer storage media

 Storage media are devices that are used to store and transfer data and information as well as work to extract them. This media can be internal or external and maybe on a server or on other computers. There are two main types of storage media for a computer, and they are as follows:

 Basic storage devices: It is a basic storage unit that is smaller than other volumes and designed to store data temporarily, so it is characterized by fast access to data, and a famous example of the types of storage media for a computer is RAM and cache.

 Secondary storage devices: It is a volume larger than the primary storage devices and is a large storage volume, and it stores data permanently and can be either internal or external and a popular example of secondary storage: hard disk, secondary drive, and USB storage device.
