Menene ƙwaƙwalwar kwamfuta?

Babu na'urar ƙwararrakin aiki da zai iya aiki ba tare da ƙwaƙwalwar ajiya ba. Koda maɗauren kwakwalwa na kwakwalwa na kwakwalwa a cikin ƙwaƙwalwar ajiyar shi ya shiga lambobi da sakamakon lissafi, musamman ma idan yazo da kwamfutar da ke da cikakken tsari. Abin takaici, masu amfani da zamani ba koyaushe suna so su san na'urar na'urar su ba. Wannan shine yanayin cigaban ci gaba: mutane suna ƙoƙari don warware matsalar da kyau, kuma ba su shiga cikin takamaiman kayan aiki ba. Saboda haka, wannan labarin ne aka yi nufi, da farko, kuma farkon, a kan m masu fasahar kwamfuta, da suke so su fadada su sãsanni da kuma koyi abin da memory kwamfutarka kuma abin da shi ne.

Mutane da yawa masu zuwa zasu yi mamakin, amma kawai RAM an shigar a kwamfuta da kwamfutar tafi-da-gidanka. Ka tuna: kawai nau'i ɗaya! Shigar da kantin kayan lantarki da tambayar mai ba da shawara don nuna ƙwaƙwalwar ajiyar kwamfutar, kada mutum ya jira jiragen tambayoyi masu ban sha'awa, kamar "wanda" (wannan shi ne a nan gaba), amma nunawa da tsarin RAM.

Na jiki, ƙwaƙwalwar aiki yana da jerin microcircuits da aka sanya a kan farantin rectangular na textolite da ake kira "ƙwaƙwalwar ajiya." A gefe ɗaya na farantin akwai sassan launi na shinge, ba ka damar shigar da tsarin a cikin mahaɗin mahaifiyar kwamfutar. A wasu lokuta, kwakwalwan kwamfuta ba su da bayyane, tun da yake suna boye a karkashin wani "tufafi" wanda zai kare su daga haɗari ba tare da haɗari ba, ƙarfin inji yana ƙaruwa, kuma, ba shakka, "tufafi" yana yin ayyukan radiator, cire ƙananan zafi daga microcircuits mai zafi. Ƙwaƙwalwar ajiyar kwamfutar ta bambanta da nau'in (SDRAM, DDR, DDR2 da 3), gaban komitin gyaran ECC, nau'in nau'i (don ƙananan littattafan girman girman farantin ya rage) da ƙarar a gigabytes. Hakika, ana iya danganta shi ga mai tsarawa.

RAM memory na kwamfuta amfani ga wucin gadi ajiya na sakamakon da CPU, duk shirye-shirye da gudu da shi a gaba ɗayansa. Bayan kashe wuta, duk bayanan da ke cikin shi batacce. Togiya - Yanayin Barci S3. Saboda haka, RAM ba ta da amfani. Tare da wasu reservations, da RAM za a iya kwatanta su da mutum ƙwaƙwalwar.

Baya ga wannan, maɓuɓɓuka daban-daban suna nuna wani ƙwaƙwalwar ajiyar ƙwaƙwalwar kwamfuta. Kodayake kalma "ƙwaƙwalwar ajiya" zuwa irin waɗannan na'urori ba ta dace kawai ba kuma ba daidai ba ne, yana da muhimmanci a faɗi game da shi. Babu shakka, bayanai da aka adana a ciki bazai ɓace ba lokacin da aka yanke ikon. Misali mai mahimmanci shi ne faifai mai wuya (drive mai wuya). Ya kasance dangin da ke kusa da zumunin rubutun gadon da aka sani da mutane da dama. Babu shakka, babu fim a ciki, amma yanayin, wanda aka sanya shi ta hanyar rikodi, ya kasance. An shigar da shirye-shirye da kuma tsarin aiki a kan sassan layin. Wani mai ɗauka, wanda ake amfani da kalmar "ƙwaƙwalwar ajiya" a wasu lokuta, shi ne CD-ROM da aka saba.

Bayan haka, waɗannan na'urorin bazai kamata a kira ƙwaƙwalwar ajiya ba. Ta hanyar misali, ana iya kwatanta su da rubutu a hannun mutum, kuma babu shakka babu wanda ya kira littafi "ƙwaƙwalwar ajiya."

Dukkanin da ke sama ya shafi ainihin na'urori. Amma banda su akwai ƙwaƙwalwar tsarin kwamfuta. Yana wakiltar dukan ƙarfin Kwayoyin, wanda aka samo daga ƙwaƙwalwar ajiya da aka sanya a kwamfutar. Alal misali, an haɗa nau'o'i biyu na 2 gigabytes kowanne - a cikin adadin ƙwaƙwalwar ajiya 4 GB. Wasu lokuta ana amfani da wannan kalmar a cikin ƙananan hankula, wanda yana nuna alamar bit-rate na tsarin aiki da aka yi amfani dashi: ko da tare da 4 GB shigarwa, tsarin bitar 32-bit yana ba ka damar aiki tare da kawai 3.25 GB. Ayyukan 64-bit sunfi samuwa, amma wannan shine batun daban-daban ...

A hanya, yana magana akan kara ƙwaƙwalwar ajiyar kwamfuta, yana nufin ƙãra yawan RAM, ba ƙananan faifai ba. Yana da sauki.
