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.

Difference between Primary and Secondary Memory

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.

A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address, which varies from zero to memory size minus one.

Difference Between Primary and Secondary Memory

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. Primary memory, also known as the main memory, is the area in a computer which stores data and information for fast access.

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. Accessing data from primary memory is faster because it is an internal memory of the computer.

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. Computer memory plays vital role in the computer industry because without computer memory entire system like as plastic box. There are two types. These memories have limited capacity for storage and made by integrated circuits IC or semiconductor components. Primary storage devices are available in two variance such as volatile and non volatile.

Там не окажется никакого Клауса, но Беккер понимал, что клиенты далеко не всегда указывают свои подлинные имена. - Хм-м, извините, - произнесла женщина.  - Не нахожу. Как, вы сказали, имя девушки, которую нанял ваш брат. - Рыжеволосая, - сказал Беккер, уклоняясь от ответа. - Рыжеволосая? - переспросила. Пауза.

Они выгравированы очень близко одно к другому и на первый взгляд кажутся произвольным набором букв, но если присмотреться повнимательнее, то… становится ясно, что надпись сделана по-латыни. - Вы что, морочите нам голову? - взорвался Джабба. Беккер покачал головой: - Отнюдь. Тут написано - Quis custodiet ipsos custodes. Это можно примерно перевести как… - Кто будет охранять охранников! - закончила за него Сьюзан. Беккера поразила ее реакция. - Сьюзан, не знал, что ты… - Это из сатир Ювенала! - воскликнула .

 Мидж, он же заместитель директора, - застонал Бринкерхофф.  - Я уверен, у него все под контролем. Давай не… - Перестань, Чед, не будь ребенком. Мы выполняем свою работу. Мы обнаружили статистический сбой и хотим выяснить, в чем. Кроме того, - добавила она, - я хотела бы напомнить Стратмору, что Большой Брат не спускает с него глаз. Пусть хорошенько подумает, прежде чем затевать очередную авантюру с целью спасения мира.

Но осуществить это намерение ей не пришлось.

Еще только начинало светать, но движение уже было довольно оживленным: молодые жители Севильи возвращались после ночных пляжных развлечений. Резко просигналив, пронесся мимо мини-автобус, до отказа забитый подростками. Мотоцикл Беккера показался рядом с ним детской игрушкой, выехавшей на автостраду.

 Твой сценарий мне понятен. ТРАНСТЕКСТ перегрелся, поэтому откройте двери и отпустите. - Именно так, черт возьми.

Все смешалось в ее голове - лица бесчисленных мужчин, склонявшиеся над ней, потолки гостиничных номеров, в которые она смотрела, мечты о том, что когда-нибудь все это кончится и она заведет детей… Внезапно, без всякого предупреждения, тело немца выгнулось, замерло и тут же рухнуло на. Это. - подумала она удивленно и с облегчением и попыталась выскользнуть из-под. - Милый, - глухо прошептала .
