Ljudi koji nemaju puno znanja o računalima skloni su vjerovati da postoje samo jedna ili dvije vrste računalne memorije^{(computer memory)} , ali to uopće nije slučaj. Zapravo, postoji nekoliko vrsta, a svaka djeluje malo drugačije od druge.

Vrste memorije u računalu

Međutim, primarni slučajevi upotrebe memorije računala su sigurno čuvanje podataka prije njihove obrade. Ideja iza ovog članka je objasniti različite vrste memorije koje možete pronaći u računalima svih oblika i veličina:

Pogon tvrdog diska^{(Disk Drive)} ( HDD ) ili Solid-State Drive ( SSD )
Brza memorija
radna memorija
ROM
Pogoni trake

Razmotrimo ovu temu detaljnije.

1] Pogon tvrdog diska^{(Hard Disk Drive)} ( HDD ) ili Solid-State Drive ( SSD )

Vrste memorije u računalu

Kada je u pitanju uobičajena memorija računala, tvrdi disk je vjerojatno na vrhu popisa. Ako želite pohraniti podatke na duge staze, tada je tvrdi disk ili SSD uređaj^{(solid-state drive)} jedna od najboljih opcija za odabir.

HDD je više kao ploča zbog svog okretnog kretanja. Ima glavu i nekoliko krakova koji se dodiruju na različitim točkama. Kada je glava pogona na određenom mjestu, informacije ili podaci se ili brišu s tvrdog diska ili se zapisuju.

Što se tiče SSD^(SSDs) -ova, oni su u nekim aspektima isti kao i HDD -ovi. ^(HDDs)Dizajnirani su za pohranjivanje informacija, ali glavna razlika je nedostatak pokretnih dijelova. Umjesto da ima glavu i ruke, oslanja se na integrirani krug za trajno pohranjivanje podataka.

Da ne spominjemo, temelje se na Flash memoriji^{(Flash Memory)} , što znači da će SSD^(SSDs) -ovi uvijek biti brži od HDD-^(HDDs) a . Međutim, vjerujemo da nemaju jednaku dugovječnost. Ako puno radite na svom računalu gdje se od vas traži upisivanje i brisanje podataka, tada koristite brzi HDD za većinu zadataka i SSD^(SSDs) za one najvažnije.

2] Flash memorija

Flash memorija postoji već dulje vrijeme, a kao što je gore navedeno, to je tehnologija na kojoj se Solid State Drives temelji. Ono što je zanimljivo s ovom vrstom memorije je činjenica da radi slično kao RAM , ali ono što ga izdvaja je njegova sposobnost čuvanja podataka čak i ako nema napajanja.

Najveći problem s Flash memorijom^{(Flash Memory)} je taj što nisu tako brzi, ali dovoljno brzi za prijenos datoteka u pokretu.

3] RAM

Za one s ograničenim znanjem, RAM je skraćenica od Random Access Memory , i oni su brzi. Ove vrste memorije mogu pristupiti podacima u bilo kojem trenutku, i obrnuto, rade kao trake na više načina.

Budući da su RAM^(RAMs) -ovi elektronički, ne sadrže pokretne dijelove u usporedbi s tvrdim diskovima, što znači da su pouzdaniji. Međutim, trebamo istaknuti da iako RAM može pohraniti informacije, to čini samo privremeno.

4] ROM

OK, dakle ROM znači Memorija^(Memory) samo za čitanje , i iako može zvučati kao RAM , ne radi na isti način. Vidite, ROM ne čuva sadržaj u memoriji ograničeno vrijeme, već zauvijek. Što god postoji, ne može se urediti ili ukloniti.

Osim toga, ROM unutar osobnog računala obično dolazi s malom baterijom, stoga bi se računalo trebalo moći pokrenuti u bilo kojem trenutku sve dok je baterija napajana.

Sada postoji nekoliko različitih kategorija RAM-a:

Programabilni ROM (PROM):^{(Programmable ROM (PROM):)} Ovaj ROM je dizajniran za pohranjivanje programa i njegov sadržaj se ne može izbrisati.
Erasable PROM (EPROM): Sadržaj EPROM -a može se izbrisati, ali samo putem UV svjetla.
Električni EPROM (EEPROM):^{(Electrically EPROM (EEPROM):)} datoteke spremljene na EEPROM-u mogu se izbrisati samo ako su izložene električnom naboju.

5] Pogoni trake

Možda prije niste čuli za trake^{(Tape Drives)} , ali za sve postoji prvi put, kaže stara izreka.

Dakle, magnetofoni^{(Tape Drives)} rade slično vrpcama ili audio kasetama. Sadrže vrpce i žlice, gdje se podaci spremaju uz pomoć polariteta vrpce.

Pogon trake^{(Tape Drive)} vjerojatno nećete pronaći u kući jer se prvenstveno koriste u srednjim i velikim tvrtkama. Razlog tome je što su izdržljivi i stabilni, stoga savršeni za dugotrajno pohranjivanje važnih datoteka.

To je to na ovu temu.

What are the Types of Memory in a computer?

People who dо not have a lot of knowledge about computers tеnd to believe there are only one or two types of computer memory, but that is not the case at all. In fact, there are several types, and each works a little differently from the other.

Types of memory in a computer

However, the primary use cases for any computer memory are to safe keep data before they are processed. Now, the idea behind this article is to explain the different types of memory you might find in computers of all shapes and sizes:

Hard Disk Drive (HDD) or Solid-State Drive (SSD)
Flash Memory
RAM
ROM
Tape Drives

Let us discuss this topic in more detail.

1] Hard Disk Drive (HDD) or Solid-State Drive (SSD)

Types of Memory in a computer

When it comes down to common computer memory, the hard disk drive is likely at the top of the list. If you want to store data for the long haul, then a hard disk drive, or solid-state drive, is one of the best options to choose from.

An HDD is more like a record due to its spinning motion. It has a head and a few arms that touch at different points. When the head of the drive is at a particular location, information or data is either being deleted from the hard drive or being written.

In terms of SSDs, they are the same as HDDs in some respects. They are designed to store information, but the major difference is the lack of moving parts. Instead of having a head and arms, it relies on an integrated circuit to store data persistently.

Not to mention, they are based on Flash Memory, which means, SSDs will always be faster than HDDs. However, we believe they do not have the same longevity. If you do a lot of work on your computer where you are required to write and delete data, then use a fast HDD for most tasks and SSDs for the most important ones.

2] Flash Memory

Flash memory has been around for a long time, and as stated above, this is the technology Solid State Drives are based on. What’s interesting with this type of memory is the fact that it works similar to RAM, but what sets it apart is its ability to keep data safe even if there is no power.

The biggest problem with Flash Memory is that they’re not that fast, but fast enough for transferring files on the go.

3] RAM

For those with limited knowledge, RAM stands for Random Access Memory, and they are fast. These types of memory are capable of accessing data at any time, and reversely, they work like tapes in more ways than one.

Because RAMs are electronic, they do not contain moving parts when compared to hard drives, which means, they are more reliable. However, we should point out that while RAM can store information, it only does so temporarily.

4] ROM

OK, so ROM means Read-only Memory, and while it may sound like RAM, it does not work in the same way. You see, ROM does not keep contents in memory for a limited time, but rather forever. Whatever is there cannot be edited or removed.

Additionally, a ROM inside of a personal computer tends to come with a small battery, therefore, the computer should be able to boot at any time as long as the battery is powered.

Now, there are several different categories of RAM:

Programmable ROM (PROM): This ROM is designed to store programs and its contents cannot be erased.
Erasable PROM (EPROM): The contents of EPROM can be erased, but only via UV light.
Electrically EPROM (EEPROM): Files saved on an EEPROM can only be deleted if exposed to an electrical charge.

5] Tape Drives

You may not have heard of Tape Drives before, but there is a first time for everything, according to an old saying.

So, Tape Drives work similarly to tapes or audio cassettes. They contain ribbons and spoons, which is where the data is saved with help of the ribbon’s polarity.

You probably won’t find Tape Drive within the home because they are primarily used within medium to large size businesses. The reason for this is because they are durable and stable, therefore, perfect for the long-term storing of important files.

That’s it on this subject.
