Hotirahoi kompyuteri fardi

Farmonho va malumothoe, ki bo sistemahoi kompyuter tahiya meshavand, dar qismi khotira nigoh doshta meshavand. Hamai kompyuterho chunin khotiraro dorand. CHi qadare, ki khotira bisyor boshad hamon qadar farmonho va malumotho dar on bisyor nigoh doshta meshavand.

CHenaki khotira bo baytho hisob karda meshavad.

Dar hayoti harruzaamon mo az raqamhoi:

0,1,2,3,4,5,6,7,8,9 istifoda mebarem, ki inro sistemai hisobkunii dahi menomand. Kompyuter akhborro faqat dar shakli adadi omoda  meshavad.  Tamomi  kompyuterhoi fardi dar sistemai hisobkunii dui kor mekunand, ki on bo 0 va 1 ifoda karda meshavad. va onhoro bit menomand. Baroi adadro ba sistemai hisobkunii dui ifoda namudan chunin amaliyot guzaronida meshavad:

(45)10=(x)2

Vohidi khurdtarini akhbor bit meboshad, ki qimathoi adadii 0 va 1-ro qabul mekunad. Vohidi buzurgtari akhbor bayt, kilobayt, megabayt, gigabayt, petabayt  va terabayt  meboshad.

Pas, adadi 45 az sistemai hisobkunii dahi dar sistemai hisobkunii dui ba 101101 barobar ast. Hasht bit ba yak bayt barobar ast. Pas

  • 210 bayt barobar ba 1 kilobayt,
  • 1 kilobayt barobar ba 1024 bayt,
  • 1 megabayt barobar ba 1024 kilobayt,
  • 1 gigabayt barobar ba 1024 megabayt,
  • 1 terabayt barobar ba 1024 gigabayt,
  • 1 petabayt barobar ba 1024 terabayt.

Dar bisyorii kompyuterhoi fardii hozirazamon khotirai doroi na kamtar az 512 megabayt vasl karda shudaand.

Rasmi khotirai kompyuter

Dar bisyori holatho mo bo kompyuterhoi doroi khotirai 1 gigabayt va az on ziyodtar vomekhurem.

Qayd kardan zarur ast, ki solhoi 2009-2010 bo kompyuterhoe vomekhurem, ki khotiraashon ba 1-4 gigabayt barobar ast.

Baroi bo barnomahoi bisyor bo surati baland kor kardan    boyad kompyuter khotirai kalontar (ziyodtar) doshta boshad. Ba khotirai kompyuter  metavonem boz khotira zam namoem, yane metavonem onro vase namoem. Agar zudii khotira khurd boshad, yane khotirai kompyuter az 512 megabayt kamtar boshad,  dar protsessori in kompyuterho amaliyotho susttar  ijro karda  meshavand. SHumo mekhohed, ki dar vaqti kor kardan bo kompyuter na bo yak barnoma, balki bo 3-4 barnoma kor kuned. Dar in holat sust yo tez budani khotirai kompyuter ba SHumo malum megardad.
