Data storage is a common term for archiving data or information in a storage medium for use by a computer. A computer stores data or information using several methods, which leads to different levels of data storage.

Memory is very much like our brain as it is used to store data and instructions. Computer memory is the storage space where data is to be processed, and instructions needed for processing are stored. The memory is divided into a large number of smaller portions called the cell. What is Primary Memory? Primary memory is the main memory of the computer system.
A storage device is a piece of computer hardware used for saving, carrying and pulling out data. It can keep and retain information short-term or long-term. It can be a device inside or outside a computer or server.
Other terms for storage device is storage medium or storage media. A storage device is one of the basic elements of any computer device. It almost saves all data and applications in a computer except for hardware firmware. It comes in different shapes and sizes depending on the needs and functionalities.

How Computers Work: Disks And Secondary Storage
A storage device is a piece of hardware that is primarily used for storing data. Every desktop computer, laptop, tablet, and smartphone will have some kind of storage device within it, and you can also get standalone, external storage drives that can be used across multiple devices. Storage is necessary not just for saving files, but also for running tasks and applications. As technology has advanced over time, data storage devices have also evolved in a major way. Nowadays, storage devices come in many shapes and sizes, and there are a few different types of storage device that cater to different devices and functions. A storage device is also known as a storage medium or storage media, and digital storage is measured in megabytes MB , gigabytes GB , and, these days, terabytes TB.
You know that processor memory, also known as primary memory, is expensive as well as limited. The faster primary memory are also volatile. If we need to store large amount of data or programs permanently, we need a cheaper and permanent memory. Such memory is called secondary memory.
Computer storage devices are typically classified into primary storage or main memory on the one hand, and secondary storage or peripheral storage on the other. Primary memory also includes registers, cache, and video memories, but we will ignore them for this discussion because their existence does not affect the principal differences between primary and secondary memory. Along with a faster CPU, every new model of computer seems to come with more main memory. As memory size continues to increase, is it possible that relatively slow disk storage will be unnecessary? Probably not, because the desire to store and process larger files grows at least as fast as main memory size.
Those all data are saved in two different modes it can either temporary or permanent nature. All data are stored in computer memory computer storage device in the digital form such as binary form like as 0 and 1. Users can retrieves of saved instruction or information anytime when they are needed.

Все зависит оттого, что выбрал Танкадо. Чем больше это число, тем труднее его найти. - Оно будет громадным, - застонал Джабба. - Ясно, что это будет число-монстр.
ГЛАВА 118 - Это может служить доказательством, - решительно заявил Фонтейн. - Танкадо избавился от кольца. Он хотел, чтобы оно оказалось как можно дальше от него - чтобы мы его никогда не нашли. - Но, директор, - возразила Сьюзан, - это не имеет смысла.
Внезапно Сьюзан вспомнила, что он должен быть в лаборатории систем безопасности. Она кружила по пустому кабинету, все еще не преодолев ужас, который вызвало у нее общение с Хейлом. Надо выбираться из шифровалки. Черт с ней, с Цифровой крепостью.
Фил физически ощущал, что времени остается все меньше. Он знал: все уверены, что он ушел.
