Dadka aan aqoon badan u lahayn kombayutarada waxay u janjeeraan inay rumaystaan ​​inay jiraan hal ama laba nooc oo ah xusuusta kombayutarka^{(computer memory)} , laakiin taasi maahan arintu gabi ahaanba. Dhab ahaantii, waxaa jira dhowr nooc, oo mid kastaa wuxuu u shaqeeyaa wax yar oo ka duwan kan kale.

Noocyada xusuusta kumbiyuutarka

Si kastaba ha ahaatee, kiisaska aasaasiga ah ee isticmaalka kombiyuutar kasta waa in la xafido xogta ka hor inta aan la farsamayn. Hadda, fikradda ka dambeysa maqaalkani waa in la sharaxo noocyada kala duwan ee xusuusta ee laga yaabo inaad ka heli karto kombiyuutarada nooc kasta iyo cabbir kasta:

1. Hard Disk Drive -ka ( HDD ) ama Solid-State Drive ( SSD )
2. Xusuusta Flash
3. RAM
4. ROM
5. Tape Drives

Aan ka hadalno mowduucan si faahfaahsan.

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

Marka ay timaado xusuusta kombuyuutarka caadiga ah, diskka adag wuxuu u badan yahay inuu ku jiro liiska ugu sarreeya. Haddii aad rabto inaad kaydiso xogta muddada dheer, markaa disk adag , ama darawal adag^{(solid-state drive)} , waa mid ka mid ah fursadaha ugu fiican ee laga dooran karo.

HDD wuxuu^(HDD) u eg yahay rikoodhka sababtoo ah dhaqdhaqaaqiisa wareegtada ah. Waxay leedahay madax iyo dhawr gacmood oo meelo kala duwan taabanaya. Marka madaxa darawalku uu joogo meel gaar ah, macluumaadka ama xogta ayaa laga tirtirayaa Hard Drive-ka ama waa la qorayaa.

Marka la eego SSD^(SSDs) -yada , waxay la mid yihiin HDD^(HDDs) -yada dhinacyada qaarkood. Waxaa loogu talagalay in lagu kaydiyo macluumaadka, laakiin farqiga ugu weyni waa la'aanta qaybaha dhaqaaqa. Halkii ay lahaan lahayd madaxa iyo gacmaha, waxay ku tiirsan tahay wareegga isku dhafan si ay u kaydiso xogta si joogto ah.

Ma aha in la xuso, waxay ku salaysan yihiin Flash Memory , taas oo macnaheedu yahay, SSDs had iyo jeer way ka dhaqso badan yihiin HDDs . Si kastaba ha ahaatee, waxaan aaminsanahay inaysan haysanin cimri dherer la mid ah. Haddii aad shaqo badan ka qabato kumbuyuutarkaaga oo lagaaga baahan yahay inaad qorto oo aad tirtirto xogta, ka dib u isticmaal HDD degdeg ah inta badan hawlaha iyo SSD^(SSDs) -yada kuwa ugu muhiimsan.

2] Flash Memory

Xusuusta Flash^(Flash) waxay jirtay muddo dheer, sida kor lagu sheegay, tani waa tignoolajiyada Solid State Drives ay ku saleysan yihiin. Waxa xiisaha leh ee noocan ah xusuusta waa xaqiiqda ah in ay u shaqeyso si la mid ah RAM , laakiin waxa ka soocaya waa awoodda ay u leedahay in ay xafiddo xogta xitaa haddii aysan jirin awood.

Dhibka ugu weyn ee Flash Memory -da ayaa ah in aanay sidaa u degdegsanayn, balse si degdeg ah ugu filan wareejinta faylasha marka ay socoto.

3] RAM

Kuwa aqoonta xaddidan leh, RAM waxay u taagan tahay Random Access Memory , waana dhakhso badan yihiin. Noocyada noocaan ah waxay awood u leeyihiin inay helaan xogta wakhti kasta, oo ka soo horjeeda, waxay u shaqeeyaan sida cajalado siyaabo badan oo ka badan hal.

Sababtoo ah RAM-yadu^(RAMs) waa elektaroonig, kuma jiraan qaybo dhaqaaqa marka la barbar dhigo darawallada adag, taas oo macnaheedu yahay, waa la isku halleyn karaa. Si kastaba ha ahaatee, waa in aan tilmaamno in iyada oo RAM uu kaydin karo macluumaadka, uu kaliya si ku meel gaar ah u sameeyo.

Akhri^(Read) :  Waa maxay faraqa u dhexeeya RAM iyo ROM^{(What is the difference between RAM and ROM)} ?

4] ROM

OK, marka ROM waxa ay ka dhigan tahay Xusuus^(Memory) -qor kaliya , iyo in kasta oo ay u ekaan karto RAM , uma shaqeeyo si la mid ah. Waxaad arkaysaa, ROM -ku waxyaalaha ku jira kuma hayo xusuusta wakhti xaddidan, laakiin waa weligeed. Wax kasta oo jira lama tafatirin karo, lamana saari karo.

Intaa waxaa dheer, ROM- ka gudaha kumbiyuutarka gaarka ah wuxuu u eg yahay inuu la yimaado batari yar, sidaas darteed, kumbiyuutarku waa inuu awood u leeyahay inuu kor u qaado wakhti kasta ilaa iyo inta uu batteriga ku shaqeynayo.

Hadda, waxaa jira dhowr qaybood oo kala duwan oo RAM ah:

• Programmable ROM (PROM): ROM- kan waxaa loogu talagalay in lagu kaydiyo barnaamijyada oo waxa ku jira lama tirtiri karo.
• PROM-ka la tirtiri karo (EPROM):^{(Erasable PROM (EPROM):)} Waxa ku jira EPROM waa la tirtiri karaa, laakiin kaliya iyada oo loo marayo iftiinka UV.
• Koronto ahaan EPROM (EEPROM):^{(Electrically EPROM (EEPROM):)} Faylasha lagu keydiyo EEPROM waa la tirtiri karaa oo keliya haddii ay soo gaarto koronto.

5] Cajalado

Waxaa laga yaabaa inaadan horay u maqlin Tape Drives , laakiin waxaa jira markii ugu horeysay wax kasta, sida uu qabo odhaah hore.

Markaa, Tape Drives waxay u shaqeeyaan si la mid ah cajaladaha ama cajaladaha maqalka ah. Waxay ka kooban yihiin xargaha iyo malqacadaha, taas oo ah meesha xogta lagu kaydiyo iyadoo la kaashanayo polarity ribbon.

Waxay u badan tahay inaadan ka heli doonin Tape Drive gudaha guriga sababtoo ah waxaa ugu horrayn lagu isticmaalaa meheradaha cabbirkoodu dhexdhexaad yahay iyo kuwa waaweynba. Sababta tani waa sababtoo ah waxay yihiin kuwo waara oo xasilloon, sidaas darteed, waxay ku fiican yihiin kaydinta muddada dheer ee faylasha muhiimka ah.

Taasi waa mawduucan.

What are the Types of Memory in a computer?

Peоple who do not have a lot of knowledge abоut computers tend to believe there are only one or two typеs 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:

1. Hard Disk Drive (HDD) or Solid-State Drive (SSD)
2. Flash Memory
3. RAM
4. ROM
5. Tape Drives

Let us discuss this topic in more detail.

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

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.
