RAM waxa ay u taagan tahay Random Access Memory^{(RAM stands for Random Access Memory)} , waa qayb aad u muhiim ah oo elegtarooniga ah oo looga baahan yahay kombuyuutarku si uu u shaqeeyo, RAM waa nooc kayd ah oo CPU u isticmaasho si ay u kaydiso xogta shaqada ee hadda jirta. Waxaa laga heli karaa dhammaan noocyada kala duwan ee qalabka xisaabinta sida Smartphones, PC-yada, tablets, servers, iwm.

Maadaama xogta ama xogta si aan kala sooc lahayn loo helo, waqtiyada wax-akhrinta iyo qorista aad ayay uga dheereeyaan marka loo eego kaydinta kale ee kaydinta sida CD-ROM-ka^(CD-ROM) ama Hard Disk -yada oo xogta lagu kaydiyo ama la soo saaro si isdaba-joog ah taas oo aad u gaabis ah habka soo saarista. Xataa xog yar oo lagu kaydiyo badhtanka isku xigxiga waa in aan marsiin doonaa taxanaha oo dhan.

RAM wuxuu u baahan yahay awood uu ku shaqeeyo, markaa macluumaadka ku kaydsan RAM waa la tirtiraa isla marka kombayutarka la damiyo. Sidaa darteed^(Hence) , waxaa sidoo kale loo yaqaan xusuusta Volatile^{(Volatile Memory)} ama Kaydinta Ku Meel Gaarka ah.

Motherboard - ku waxa uu yeelan karaa tiro kala duwan oo meelo xusuusta ah, celceliska Motherboard -ka macmiisha ayaa yeelan doona inta u dhaxaysa 2 iyo 4 ka mid ah.

Si Xogta^(Data) ama program-yada loogu fuliyo kombayutarka, waxa ay u baahantahay in marka hore lagu shubo ram.

Markaa xogta ama barnaamijka marka hore waxa lagu kaydiyaa Hard Drive-ka kadibna Hard Drive-ka ayaa laga soo saarayaa oo lagu shubayaa RAM . Marka la shubo, CPU -gu hadda wuu heli karaa xogta ama hadda wuu socodsiinayaa barnaamijka.

Waxaa jira macluumaad ama xog badan oo si joogto ah loo galo si ka badan kuwa kale, haddii xusuusta ay aad u yar tahay waxaa laga yaabaa inay awoodi weydo inay hayso dhammaan xogta uu CPU u baahan yahay. Marka tani dhacdo markaas qaar ka mid ah xogta xad-dhaafka ah ayaa lagu kaydiyaa darawalka adag si loo magdhabo xusuusta hoose.

Haddaba halkii ay xogtu si toos ah uga socon lahayd RAM -ka una gudbi lahayd CPU -ga , waa in ay ka soo saartaa Hard Drive-ka kaas oo xawaarihiisa aad u gaabis ah u socda, habkani waxa uu si weyn hoos ugu dhigayaa kombiyuutarka. Tan waxaa si fudud wax looga qaban karaa iyadoo la kordhiyo tirada RAM -ka ee u diyaarsan kombuyuutarku inuu isticmaalo.

Laba nooc oo kala duwan oo RAM ah

i) DRAM ama RAM Dynamic^{( DRAM or Dynamic RAM)}

Dram waa xusuusta ka kooban capacitors, kaas oo la mid ah baaldi yar oo kaydiya korontada, waxa uu ku jiraa capacitors-kan uu hayo macluumaadka. Sababtoo ah riwaayaduhu waxay leeyihiin capacitors u baahan in lagu cusboonaysiiyo koronto joogto ah, wax kharash ah kuma hayaan muddo aad u dheer. Sababtoo ah capacitors waa in si firfircoon loo cusboonaysiiyaa, waa meesha ay ka helaan magaca. Noocan tignoolajiyada RAM ayaan hadda si firfircoon loo isticmaalin iyadoo ay ugu wacan tahay horumarinta tignoolajiyada RAM aad u hufan oo aad u degdeg badan taasoo aan horay uga hadli doono.

ii) SDRAM ama DRAM isku mid ah^{(SDRAM or Synchronous DRAM)}

Tani waa tignoolajiyada RAM -ka oo si weyn looga isticmaalo aaladaha elektiroonigga ah hadda. ^(RAM)SDRAM sidoo kale waxay leedahay capacitors la mid ah DRAM , si kastaba ha ahaatee, farqiga u dhexeeya SDRAM iyo DRAM^{(difference between SDRAM and DRAM)} waa xawaaraha, tignoolajiyada DRAM ee da'da weyn waxay u socotaa si tartiib tartiib ah ama u shaqeysa si aan kala sooc lahayn marka loo eego CPU , tani waxay ka dhigaysaa xawaaraha wareejinta inuu dib u dhaco sababtoo ah calaamadaha aan la isku dubaridin.

SDRAM wuxuu ku shaqeeyaa si la mid ah saacadda nidaamka, waana sababta ay uga dhaqso badan tahay DRAM . Dhammaan calaamaduhu waxay ku xidhan yihiin saacadda nidaamka si loo xakameeyo wakhtiga.

RAM waxa lagu xidhay Motherboard-ka qaab ka mid ah modules-ka laga saari karo isticmaalaha kuwaas oo loo yaqaan SIMMs (Single in-line memory modules) iyo DIMM-yada (dual in-line memory modules)^{(SIMMs (Single in-line memory modules) and DIMMs (dual in-line memory modules))} . Waxaa loo yaqaan DIMM^(DIMMs) -yada sababtoo ah waxay leedahay laba saf oo madax-bannaan oo biinanka ah mid dhinac kasta ah halka SIMM^(SIMMs) -yadu ay leeyihiin hal saf oo biinanka ah oo keliya hal dhinac. Dhinac kasta oo ka mid ah moduleka wuxuu leeyahay 168, 184, 240 ama 288 biin.

Isticmaalka SIMM^(SIMMs) -yada hadda waa duugoobay maadaama awoodda xusuusta RAM ay labanlaabtay DIMM^(DIMMs) -yada .

DIMM^(DIMMs) -yadani waxay ku yimaadaan awoodo xusuuseed oo kala duwan, kuwaasoo u dhexeeya meel kasta oo u dhaxaysa 128 MB ilaa 2 TB. DIMM^(DIMMs) -yadu waxay gudbiyaan 64-bit oo Xog^(Data) ah markiiba marka la barbar dhigo SIMM^(SIMMs) -yada kuwaas oo markiiba gudbiya 32-bit oo Xog^(Data) ah.

SDRAM sidoo kale waxaa lagu qiimeeyaa xawaare kala duwan, laakiin ka hor inta aynaan u gelin taas, aan fahamno waxa ay tahay waddada xogta.

Xawaaraha CPU waxaa lagu qiyaasaa wareegyada saacada, sidaas darteed hal wareeg oo saacad ah, ama 32 ama 64 bits oo xog ah ayaa la isugu gudbiyaa CPU iyo RAM , wareejintan waxaa loo yaqaannaa dariiqa xogta.

Markaa mar kasta oo uu kor u kaco xawaraha saacada CPU waxa uu kombuyuutarku noqon doonaa mid dhakhso badan.

Si la mid ah, xitaa SDRAM waxa ay leedahay xawli saacadeed oo wax akhrinta iyo qorista ay ku dhici karaan. Markaa sida ugu dhakhsaha badan ee saacada RAM -ka ay u xawaarayso si dhakhso leh ayay hawluhu u dhacaan iyaga oo kor u qaadaya waxqabadka processor-ka. Tan waxa lagu qiyaasaa tirada wareegyada ay samayn karto oo lagu tiriyo megahertz. Markaa, haddii RAM lagu qiimeeyay 1600 MHz , waxay ku shaqaysaa 1.6 bilyan oo wareeg ilbiriqsikii.

Marka, waxaan rajeyneynaa in tani ay kaa caawisay inaad fahamto sida RAM iyo noocyada kala duwan ee tignoolajiyada RAM u shaqeeyaan.^(RAM)

What is RAM? | Random Access Memory Definition

RAM stands for Random Access Memory, it is a very crucial electronic component that is required for a computer to run, RAM is a form of storage that CPU uses to store the current working data temporarily. It can be found in all kinds of computing devices such as Smartphones, PCs, tablets, servers, etc.

Since the information or data is randomly accessed, the read and write times are much faster compared to other storage mediums such as CD-ROM or Hard Disk Drives where the data is stored or retrieved sequentially which is far slower a process as a result to retrieve even a small amount of data stored in the middle of the sequence we will have to go through the entire sequence.

RAM requires power to work, so the information stored in RAM gets erased as soon as the computer is switched off. Hence, it is also known as Volatile Memory or Temporary Storage.

A Motherboard can have a various number of memory slots, the average consumer Motherboard will have between 2 and 4 of them.

In order for Data or programs to be executed on a computer, it needs to be loaded into ram first.

So the data or program is first stored on to the hard drive then from the hard drive, it is retrieved and loaded into RAM. Once it’s loaded, the CPU can now access the data or run the program now.

There is a lot of information or data that gets accessed more frequently than others, if the memory is too low it might not be able to hold all the data that the CPU needs. When this happens then some of the excess data gets stored on the hard drive to compensate for the low memory.

So instead of the data directly going from RAM to the CPU, it has to retrieve it from the hard drive that has very slow access speed, this process significantly slows down the computer. This can be easily tackled by increasing the amount of RAM available for the computer to use.

Two Different types of RAM

i) DRAM or Dynamic RAM

Dram is a memory that contains capacitors, which is like a small bucket that stores electricity, and it’s in these capacitors it holds the information. Because dram has capacitors that require to be refreshed with electricity constantly, they do not hold a charge for very long. Because the capacitors have to be dynamically refreshed, that’s where they get the name from. This form of RAM technology is no longer being actively used due to the development of far efficient and faster RAM technology which we will discuss ahead.

ii) SDRAM or Synchronous DRAM

This is the RAM technology that is widely used in our electronics now. SDRAM also has capacitors similar to DRAM, however, the difference between SDRAM and DRAM is the speed, the older DRAM technology runs slower or operates asynchronously than the CPU, this makes the transfer speed to lag because the signals are not coordinated.

SDRAM runs in sync with the system clock, which is why it is faster than DRAM. All the signals are tied to the system clock for a better-controlled timing.

RAM is plugged into the motherboard in the form of user-removable modules that are called SIMMs (Single in-line memory modules) and DIMMs (dual in-line memory modules). It is called DIMMs because it has two independent rows of these pins one on each side whereas SIMMs only have one row of pins on one side. Each side of the module has either 168, 184, 240 or 288 pins.

The usage of SIMMs is now obsolete since the memory capacity of the RAM doubled with DIMMs.

These DIMMs come in different memory capacities, that range anywhere between 128 MB to 2 TB. DIMMs transfer 64 bits of Data at a time compared to SIMMs which transfer 32 bits of Data at a time.

SDRAM is also rated at different speeds, but before we delve into that, let us understand what data path is.

The speed of CPU is measured in clock cycles, so in one clock cycle, either 32 or 64 bits of data get transferred between the CPU and RAM, this transfer is known as data path.

So the higher the clock speed of a CPU the faster the computer will be.

Similarly, even SDRAM has a clock speed at which the read and write can take place. So the faster the RAM’s clock speed the faster the operations occur boosting the processor performance. This is measured in the number of cycles it can perform counted in megahertz. So, if RAM is rated at 1600 MHz, it performs 1.6 billion cycles per second.

So, we hope this helped you understand how RAM and different types of RAM technologies work.
