WAA MAXAY MEMORY !!!

Memory-da

Memory-du waxay u kala baxdaa laba nooc oo kala ah: ROM (Read Only Memory) iyo RAM (Random Access Memory). Casharkeenaan waxaa kaliya oo aan kaga hadli doonnaa nooca dambe ee RAM. Mar kasta oo aan casharkaan ku soo qaadno Memory waxaan ula jeednaa nooca RAM oo kaliya.

Waa Maxay RAM?

RAM (Random Access Memory) waa halka si ku meelgaar ah loogu kaydiyo akhbaarta uu processor-ku markaas gacanta ku hayo iyo program-yada markaa shidan (running programs). Tusaale ahaan haddaad rabto inaad wax qorato waxaad horta shiddaa program-ka aad wax ku qorato sida Word. Markaad program-kaas shiddo waxaa Memory-da lagu kaydiyaa koobi ah program-kaas, koobigaas ayaana lagu tusaa si aad wax ugu qorato. Muddada aad wax qorayso waxaa akhbaarta aad qorto lagu kadiyaa Memory-da, waxaana halkaa lagu haynayaa ilaa inta uu kumbiyuutarku shidan yahay ama aad program-ka Word ka xirayso. Haddiise kumbiyuutarka la damiyo ka hor inta aadan kaydin akhbaartaasi way lumaysaa.

Tusaalaha ugu caansan ee la soo qaato marka la sharxayo sida uu kumbiyuutarku wax u kaydiyo waa iyadoo kumbiyuutarka lagu matalo xafiis yar oo ay yaallaan miis iyo armaajo lagu kaydiyo dukumentiga xafiiska. Armaajadu waxay u taagan tahay Hard Disk-ga oo ah halka sida joogtada ah loogu kaydiyo akhbaarta iyo program-yada kumbiyuutarka ku jira. Miiskuna wuxuu u taagan yahay Memory-da. Qofka xafiiska ka shaqaynaya (oo u taagan Processor-ka) wuxuu armaajada kala soo baxaa hadba dukumentiga uu rabo inuu wax ka qabto wuxuuna ku kala fidiyaa miiska dushiisa. Waxaa caadi ah in qofka xafiis ka shaqaynayaa uu dukumentiyo fara badan ku haysto miiska dushiisa. Mar kasta oo baaxadda miisku ay sii weynaataba waxaa badanaya tirada dukumentiyada dushiisa la saari karo. Sidaa si la mid ah ayuu kumbiyuutarku program-yada iyo hawlaha uu markaas gacanta ku hayo ugu kaydsadaa Memory-da. Mar kasta oo ay baaxadda Memory-du sii weynaataba waxaa badanaya akhbaarta lagu keydin karo iyo tirada program-yada isku mar kuu furnaan karo. Memory-da la'aanteed kumbiyuutarku wax hawl ah ma qaban karo. Sidaa darteed Memory-du waxay ka mid tahay qaybaha ugu muhiimsan kumbiyuutarka.

Baaxadda Memory-da waxaa lagu cabbiraa waxa loo yaqaan "Byte" oo u dhigma hal xaraf. 1024-kii byte waxay noqdaan hal KiloByte (KB). Kunkii KB waxay noqdaan hal MegaByte (MB). Kunkii MB-na waxay noqdaan hal GigaByte (GB). Memory-du waxay ku dul rakiban tahay kaarar yar yar oo uu dhererkoodu qiyaas ahaan le'eg yahay 10 ilaa 15 cm (Fiiri sawirka). Kaararkaasi waxay u kala baxaan laba nooc oo kala ah SIM (Single Inline Memory Module) iyo DIM (Dual Inline Memory Module). Kaararkaas waxaa la gadaa iyagoo baaxadda Memory-da ku dul rakibani ay tahay 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, 32 MB, 64 MB ama 128 MB.

Haddaan dib ugu noqonno tusaalihii xafiiska, mar kasta oo uu miiska xafiisku sii weynaadaba waxaa badanaya tirada dokumentyada isku mar dushiisa la saari karo islamarkaana waxaa fududaanaya helitaanka dokumenti ka mid ah dokumentiyada saaran miiska dushiisa, maadaama uu miisku waasac yahay oo aan loo baahanayn in dokumentiyada la is kor saaro oo ay markaa is qariyaan. Sidaa si le'eg ayaa mar kasta oo ay baaxadda Memory-da kumbiyuutarku sii weynaataba waxaa bata tirada porgamyada isku mar kuu furnaan kara iyo xaddiga akhbaarta Memory-da lagu kaydin karo. Waxaa kale oo fududaanaya helitaanka wixii akhbaar ah ee Memory-da looga baahdo. Taasina waxay kor u qaadaysaa xawaaraha hawl qabadka kumbiyuutarka.
