| ASCII Windows belgilar kodi jadvali.
Maxsus (boshqaruv) belgilarning tavsifi
Shuni ta'kidlash kerakki, dastlab ASCII jadvalining boshqaruv belgilari teletayp ma'lumot almashinuvini, teshilgan lentadan ma'lumotlarni kiritish va tashqi qurilmalarni eng oddiy boshqarish uchun ishlatilgan.
Hozirgi vaqtda jadvaldagi ASCII boshqaruv belgilarining aksariyati endi ushbu yukni o'z zimmasiga olmaydi va undan boshqa maqsadlarda foydalanish mumkin.

Matnli axborotlarni kodlash usullari
1.1. Ssetial tayoqchasi yordamida kodlash.
1.2. “Sezar shifri” yordamida kodlash. Matndagi harf alifboda o’zidan keyin kelgan uchunchi harfga almashtiriladi. Qadimgi rim imperatori Yuliy Sezar o’ylab topgan.
1.3. “Morze alifbosi” yordamida kodlash. Matndagi harflar quyidagi jadvalda keltirilgan belgilarga almashtiriladi.
Bu ususl yordamida “elektron” so’zi quyidagicha kodlanadi:
1.4. “Alifbo usuli” yordamida kodlash. Matndagi harflar bizga ma’lum bo’lgan alifbodagi harflarni ularning tartibini ko’rsatuvchi sonlar bilan almashtirish orqali kodlanadi.
Masalan, “Bugun havo issiq” degan axborot quyidagi ko’rinishda kodlanadi:
Bu holda tinish belgilari va boshqa kerakli belgilarni ham maxsus sonlar bilan ifodalash va ularni matnga kiritish mumkin.
Alifbodagi harflar ketma-ketligini tartiblashning bir qancha usuli bor. Masalan, quyidagi tartibni keltirish mumkin:
Bu usulni aralashtirilgan alifbo usuli deyiladi. Yuqoridagi matn bu holda quyidagi ko’rinishni oladi:
Bu axborotni yuqoridagi jadvaldagi ma’lumotlarni bilmasdan qayta kodlash juda murakkab.
