RAM-memory da kuma yadda yake aiki

Yau za mu yi magana game da abin da yake a RAM-memory. Bari mu fara da ka'idar. Duk wani kwamfuta shirin gudu a kan kisa a tsarin aiki yanayi, kazalika da kai tsaye a cikin na'ura code da aka shigar wanda ke aiki a wani hanya mai sa na ma'ana wadanda kuma zeros - kwatancin na jihar na transistors.

Lokacin da generated data koguna, wanda aiki da CPU. Idan shirye-shirye da aka adana a kan wuya tafiyarwa, CDs, kuma flash tafiyarwa, wato, dukan waɗanda kafofin watsa labarai, da bayanai da cewa ba bace bayan ya sauya sheka kashe da samar da lantarki, da RAM-ƙwaƙwalwar ne na musamman ajiya na'urar, gaba daya dogara a kan gaban abinci a cikin dabaru haihuwarka. Kanta wani acronym (RAM) ne wanda aka samu daga cikin uku Turanci kalmomi - da Random Access Memory da, wanda za a iya fassara ta a matsayin bazuwar damar žwažwalwar ajiya. A wani Rasha harshen da aka sani Kalmar "RAM" - bazuwar damar žwažwalwar ajiya. Dukansu sharuddan bayyana quite tabbatacce, cewa shi ne mai RAM memory.

A overall manufa na aiki

RAM-memory shigar a kwamfutarka, koyi mai sauki ne: shi ne mai sa na kwakwalwan kwamfuta soldered da tushe - kananan textolite wuya tare da jeri biyu na jan zamiya lambobi, ta hanyar abin da shi ta haɗu da motherboard haši. Wani lokaci, wadannan Scarves ake kira alluna, ko, mafi daidai, da kayayyaki. Dangane da yawan ramummuka, za'a iya samun dama. Total girma, wanda ya da alaka RAM-memory, ƙaddara da halaye kafa na kwakwalwan kwamfuta. Idan muka magana game da na'urar kawai, kowane daga cikinsu shi ne mai sa na transistors - lantarki semiconductor sauya. A peculiarity wannan kashi ne cewa, tare da taimakon wani sauki dabaru kewaye za a iya sarrafawa da ta jiha: yin shi conductive halin yanzu (bude) ko ba (rufaffiyar).

Saboda haka, da sauki coding, yana yiwuwa su yi hira cikin binary ragowa. Alal misali, bude jihar - shi ne mai naúrar, da kuma rufe - sifili. Bayan ya sauya sheka kashe ƙarfin lantarki dole ne kananan, goyon bayan da wani zabi jiha. Wannan shi ne dalilin da ya sa ikon da aka kashe, duk data adana a RAM aka rasa har abada, tun transistors an koma zuwa tsaka tsaki matsayi. Togiya - flash tafiyarwa, RAM-memory wanda aka shirya daban, kamar amfani da modified iyo ƙofar transistors. Amma cewa shi ne gaba ɗaya daban-daban labarin.

Tunanin cewa ka bukatar a ci gaba da shirin a guje (tuna) wani adadin. The processor sabobin tuba shi a cikin wani daidai sa na ragowa da ta aika da su zuwa ga mai kula, wanda ya musanya masa a jihar na bukatar yawan transistors a kan wani guntu RAM. Bayan nan, da lambar da za a adana a can har sai wani kuma baya da irin ƙarfin lantarki wadata (ikon kashe) ko umurnin for erasing aka kafa.

The darajar da kwamfuta tsarin

RAM ne mai muhimmanci bangaren na kwamfuta. Ba tare da shi, da aiki shi ne ba zai yiwu ba. Haka kuma, daga ikon yinsa da kuma halaye da kafofin dogara tsarin yi. Wannan shi ne quite halitta: wani shirin rubuta wa memory cell ba guda lamba (kamar yadda a cikin misali a sama), da kuma sa. Saboda haka, a halin da ake ciki na iya tashi a lokacin da transistor aka bar free. A wannan yanayin, da karin bayanai ne sake saiti zuwa rumbunka ko akwai wani tilasta rufe na gudãna aikace-aikace. Duk da wannan daukan lokaci. Ba mamaki, da memory for wasanni - mafi wuya na wadannan shirye-shirye ya zama na wani dace size (ya fi girma shi ne mafi alhẽri). In ba haka ba, a wasan tsari za a jinkirta, jerks.
