External kwamfuta memory

Zuwan da kwamfuta da kuma, daidai da, da mai rumfa bayanai adana a kan daban-daban da kafofin watsa labaru, ya kai ga cewa muna bukatar mu fi da kuma ƙarin bayani repositories. Wannan shi ne dalilin da ya sa kafofin watsa labarai na waje, ta hanyar abin data iya shigar da sirri kwamfuta da aka ƙirƙira ga ajiya da kuma musayar bayanai.

Saboda haka, duk da kwamfuta ta ƙwaƙwalwar za a iya kasu kashi biyu:

- nasu lantarki (ciki) memory.

- External Memory PC aka located a gefe na kafofin watsa labarai.

Ciki tafiyarwa ake kira m ko gyarawa, suna saka a cikin kwamfuta tsarin naúrar kuma yawanci kira wuya DISKs.

Matsayin mai mulkin, da adadin data a gefe na kafofin watsa labarai ne da yawa sau fi girma cewa yana adana kai tsaye a kan kwamfuta. Yawancin lokaci, akwai rewriting dukan shirye-shirye da kuma fayiloli zuwa wanda damar da aka ba da ake bukata duk lokacin, yayin da rumbun kwamfutarka da aka tsara don m ajiya na zama dole bayanai: da tsarin aiki da shirye-shirye, takardu, aikace-aikace da sauransu.

A lokacin, da waje memory na kwamfuta da aka wakilta wata babbar dama na'urori, amma da farko wakilin an riga an mayar da su zuwa baya floppy faifai ko, mafi kawai, da saba floppy faifai. Wadannan floppy woje aka saka a cikin wuyan drive kwamfuta, da kuma ƙwaƙwalwar su ne 1,44 megabytes.

Multimedia ci gaba jagoranci zuwa fitowan da kuma ci gaban sauran waje ajiya kafofin watsa labarai a wadda data (yawanci music, fina-finai, wasanni) ne a wani sirri kwamfuta. Wannan waje kwamfuta memory kira Laser CDs (Karamin woje). Rubuta bayanai zuwa su ake yi a digital form. Kuma idan sun aka tsara don rikodin bayanai a lokaci guda, suna da wani CD-ROM take, yayin da ƙafafun aka tsara don mahara da rikodi da kuma overwriting na bayanai, koma ga CD-RW. The damar wani misali CD-ROM Laser jere daga 690 zuwa dubu biyu megabytes.

External kwamfuta memory aka karanta da Laser fayafai amfani da wani CD-ROM-tafiyarwa, wanda suke ciki da kuma na waje.

A mafi girma girma na DVD fayafai an tsara kagaggun for rikodi da kuma watsa fina-finai. Rabuwa da ROM, RW, kazalika da karanta data daga gare su daukan wuri a kan tushen da CD-ROM drive.

Akwai wani, mafi mashahuri a lokacin irin data - kwamfuta waje memory, wanda ake ce da flash-memory. Rubuta bayanai a cikin wannan yanayin da ake yi a kan guntu cewa samar da high data mutunci, kazalika da babban gudun karatu da kuma rikodin bayanai. Flash drive to date yi tsiwirwirinsu m shahararsa ba kawai a matsayin kwamfuta na'urar, amma kuma a matsayin data ajiya a kan wayoyin hannu, kyamarori da kuma sauran kayan aiki da bukatar a na'urar for rikodin bayanai. Sun zo a cikin da yawa daban-daban iri iri na masu girma dabam, da kuma iya samun daban-daban adadin zuwa dama dubun gigabytes.

A waje memory na kwamfuta, da barin lokacin ya ci gaba da girma kundin, kira waje rumbun kwamfutarka. Su girma iya adadin zuwa dama terabytes, da kuma AMINCI data ajiya fitarwa dace. Wadannan wuya tafiyarwa suna da alaka zuwa kwamfuta ta amfani da kebul na-mashigai. Bugu da ƙari kuma, su na'urar zai iya ba kawai aiki a matsayin ƙarin data ajiya, amma kuma da aiki (da akai dangane da kwamfuta) a matsayin ci gaba da kwamfuta memory kanta. Kamar haka, akwai za a iya adana fayilolin da ake bukata domin dukan aiki da tsarin. Wannan shi ne misali na waje memory.

Ci gaba ba tsaya har yanzu, da kuma na waje kafofin watsa labarai suna kullum inganta. Data kundin suna girma, kara saukaka, kuma AMINCI. Duk da haka, ko da yaushe daraja tuna cewa wani kayan aiki na iya karya saukar a kowane lokaci. Wannan shi ne dalilin da ya sa duk da muhimmanci bayanai adana a kan kwamfutarka, shi wajibi ne don kwafi.
