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 and secondary memory differences as a function of age and education
Data storage is one of several basic, yet vital functions a computer performs. The concept of storage itself is defined by a hierarchy of four levels: primary storage, secondary storage, tertiary storage, and offline. This post will serve as a primer for those who need an introduction or refresher course. Typically located inside the computer, primary storage temporarily houses applications and data currently in use. Volatile memory such as RAM loses data as soon as the device loses power. This enables some applications to recover unsaved information in the event of a crash. ROM retains its contents even if the device loses power.
Asked by Wiki User. They are both storage devices -They are both binary system to represent data. William James. Primary Memory is connected with the motherboard. Secondary Memory are those which are connected to the computer from outside.

Computer data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit CPU of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy ,  : — which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally the fast volatile technologies which lose data when off power are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage 's Analytical Engine and Percy Ludgate 's Analytical Machine, clearly distinguished between processing and memory Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles. The former controls the flow of data between the CPU and memory, while the latter performs arithmetic and logical operations on data.

The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept. The basic difference between primary and secondary memory is that the primary memory is directly accessible by CPU whereas, the secondary memory is not directly accessible to CPU. Let us discuss some more differences between Primary and secondary memory with the help of the comparison chart shown below.
The Primary memory processes the data and instructions while the computer unit is being processing. Primary memory stores the data or instructions for quick access and direct access. The main purpose of primary memory used to store frequently used programs that can be directly accessed by the processor for further processing. When the computer is off, all the processed data of RAM automatically goes to the trash.
It is store the data, information, programs during processing in computer. It stores data either temporarily or permanent basis.

Memory is the brain of the computer which stores data and information for storing and retrieving. Just like a human brain, memory is the storage space of the computer — like a physical device — that is capable of storing data or programs temporarily or permanently. Memory is a fundamental component of the computer that is categorized into primary and secondary memory. Primary memory is the main memory of the computer which can be directly accessed by the central processing unit, whereas secondary memory refers to the external storage device which can be used to store data or information permanently. While both serve the same purpose; that is to store data or instructions for further processing by the CPU, they do it very differently.
Тебе надо лечиться от паранойи. В трубке повисло молчание. - Мидж… - Джабба попробовал извиниться. - Позволь мне объяснить.
Key Differences Between Primary and Secondary Memory
Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу. Прекрасное место для смерти, - подумал Халохот. - Надеюсь, удача не оставит. Беккер опустился на колени на холодный каменный пол и низко наклонил голову. Человек, сидевший рядом, посмотрел на него в недоумении: так не принято было вести себя в храме Божьем. - Enferno, - извиняясь, сказал Беккер.
Северная Дакота. Разумеется, это кличка. - Да, но я на всякий случай заглянул в Интернет, запустив поиск по этим словам. Я не надеялся что-либо найти, но наткнулся на учетную запись абонента. - Он выдержал паузу. - Я, конечно, предположил, что это не та Северная Дакота, которую мы ищем, но на всякий случай проверил эту запись. Представь себе мое изумление, когда я обнаружил множество сообщений Энсея Танкадо.
Парень расплылся в широкой улыбке. - А то ты не знаешь. Беккер пожал плечами. Парень зашелся в истерическом хохоте. - Ну и .
