Asosiy xotira – kompyuterning dasturlar va ma’lumotlarni saqlash uchun mo‘ljallangan komponentidir. Xotira ma’lum bir uzunlikka ega bo‘lgan axborotlarni saqlovchi yacheykalardan iborat bo‘ladi.
Hozirgi kompyuterlarning xotirasi 8-bitli, ya’ni bir baytli yacheykalardan iborat bo‘lib, xotiraga ana shu baytlarning adreslari orqali murojaat qilinadi.
Baytlarni guruhlarga birlashtirilib so‘zlar (rus tilida – слово) hosil qilinadi. 1, 2, 4 va 8 baytli, ya’ni 8, 16, 32 va 64-bitli yoki razryadli so‘z uzunliklariga ega kompyuterlar mavjud.
Ma’ruzada kompyuter xotirasining so‘z uzunliklarini, protsessorlar ichki registrlarining uzunliklarini ifodalashda va boshqa holatlarda razryad iborasi qo‘llanilgan.
