From mainframes to wearable computers

A mainframe is the most powerful type of computer. It can process and store large amounts
of data. It supports multiple users at the same time and can support more simultaneous processes than a PC. The central system is a large server connected to hundreds of terminals over a network. Mainframes are used for large-scale computing purposes in banks, big companies and universities. Mainfreym kompyuterning eng kuchli turi hisoblanadi. U katta miqdorda qayta ishlash va saqlashi mumkin
ma'lumotlardan. U bir vaqtning o'zida bir nechta foydalanuvchilarni qo'llab-quvvatlaydi va kompyuterga qaraganda bir vaqtning o'zida ko'proq jarayonlarni qo'llab-quvvatlaydi. Markaziy tizim tarmoq orqali yuzlab terminallarga ulangan katta serverdir. Mainfreymlar banklarda, yirik kompaniyalarda va universitetlarda keng ko'lamli hisoblash maqsadlarida qo'llaniladi.


A desktop PC has its own processing unit (or CPU), monitor and keyboard. It is used as a personal computer in the home or as a workstation for group work. Typical examples are the IBM PC and the Apple Macintosh. It's designed to be placed on your desk.

U xuddi shunday protsessorlari, xotira hajmi va disklari bilan ish stoli kompyuteri kabi tez ishlashi mumkin, lekin u portativ va kichikroq ekranga ega. Zamonaviy noutbuklarda TFT (Yupqa kino tranzistor) yoki
juda aniq tasvirlarni ishlab chiqaradigan LCD (Suyuq kristalli ekran) ekran.
Sichqoncha o'rniga ular klaviaturaga o'rnatilgan sensorli panelga ega - ekranda kursorni harakatlantirish uchun teginishingiz mumkin bo'lgan sezgir panel.
Ular juda ko'p ulanish imkoniyatlarini taklif qiladilar: tashqi qurilmalarni ulash uchun USB (Universal Serial Bus) portlari, xotira kartalari uchun slotlar va boshqalar. Ular batareyalar to'plami bilan birga keladi, bu esa elektr rozetkalari mavjud bo'lmaganda kompyuterdan foydalanish imkonini beradi.

Kirish uchun siz kichik klaviaturada yozasiz yoki stilusdan foydalanasiz - elementlarni tanlash, rasm chizish va hokazolar uchun sensorli ekran bilan ishlatiladigan maxsus qalam. Ba'zi modellar qo'lda yozilgan belgilarni tanib olish imkonini beruvchi qo'lyozmani aniqlashni o'z ichiga oladi. Ba'zi PDA'lar ovozni aniqlash dasturidan foydalangan holda aytilgan so'zlarni taniydi.
Ulardan mobil telefonlar yoki eslatmalar, eslatmalar va manzillarni saqlash uchun shaxsiy tashkilotchilar sifatida foydalanish mumkin. Shuningdek, ular simsiz texnologiya orqali internetga kabellarsiz kirish imkonini beradi


A wearable computer runs on batteries and is worn on the user's body, e.g. on a belt, backpack or vest; it is designed for mobile or hands-free operation. Some devices are equipped with a wireless modem, a small keyboard and a screen; others are voice-activated and can access e- mail or voice mail. Kiyiladigan kompyuter batareyalar bilan ishlaydi va foydalanuvchining tanasiga kiyiladi, masalan. kamar, xalta yoki yelekda; u mobil yoki qo'llarsiz ishlash uchun mo'ljallangan. Ba'zi qurilmalar simsiz modem, kichik klaviatura va ekran bilan jihozlangan; boshqalar ovozli faollashtirilgan va elektron pochta yoki ovozli pochtaga kirishlari mumkin
