Figure 1. 8 - digit word length _ has 64 Kbytes basic memory .
This basic in memory cells addresses value 0000 and FFFF each change possible .
Basic of memory general size 64 Kbytes (FFFF - 16 bits, 2 16 = 65536 bytes ).
now such volume memories - removable on computers , ie in controllers used .
Usually basic memory addresses are numbered 16 in the system represented by
1-rasm. 8-razryadli so‘z uzunligiga ega 64 Kbaytli asosiy xotira.
Ushbu asosiy xotirada yacheykalar adreslarining qiymati 0000 dan FFFF gacha o‘zgarishi mumkin.
Asosiy xotiraning umumiy xajmi 64 Kbayt (FFFF – 16 bit, 216=65536 bayt).
Hozirda bunday hajmli xotiralar – o‘rnatiladigan kompyuterlarda, ya’ni kontrollerlarda ishlatilmoqda.
Odatda asosiy xotira adreslari 16-lik sanoq sistemasida ifodalanadi.
word in Figure 2 length is equal to 32 degrees which was basic memory described .
Such word length has memories , Pentium processors installed on computers used .
Them cells addresses 0000 0000 and FFFF FFFF until change possible .
Of memory general size 4 GB (FFFF FFFF - 32 bits, 2 32 = 4294967296 bytes ).
The word in length 32-bit memories bytes from the right left or from left To the right depending on placement possible .
Figure 2. Word to the 32nd category length has , bytes reverse in order placed 4 GB basic memory
2-rasmda so‘z uzunligi 32-razryadga teng bo‘lgan asosiy xotira tasvirlangan.
Bunday so‘z uzunligiga ega xotiralar, Pentium protsessorlari o‘rnatilgan kompyuterlarda ishlatilmoqda.
Ularda yacheykalarning adreslari 0000 0000 dan FFFF FFFF gacha o‘zgarishi mumkin.
Xotiraning umumiy xajmi 4 Gbayt (FFFF FFFF – 32 bit, 232= 4294967296 bayt).
So‘z uzunligi 32-razryadli xotiralarda baytlar o‘ngdan chapga yoki chapdan o‘ngga qarab joylashtirilishi mumkin.
2-rasm. 32-razryadga so‘z uzunligiga ega, baytlari teskari tartibda joylashtirilgan 4 Gbaytli asosiy xotira
Figure 2 listed with a Pentium processor in memory on computers as , bytes to the right left depending on placed .
These bytes reverse in order is called placement ( rus in the language - obratnыy poryadok sledovaniya bytes ).
In Figure 3 bytes right in order placed memory drawing listed .
It 's kind of memory bytes right in order placed called memory ( Russian ) In the language - pryamoy poryadok sledovaniya bytes ) and it belongs to the SPAR S family mansub processors has which was on servers used .
