Kompyuterlarni texnik ta’minoti va tizimlari O’qituvchi: I.Tojimamatov Tayyorladi: N.Saydolimov 1. Kompyuterni tuzilishi va turlari. 2. Kompyuterni texnik ta’minoti. 3. Kompyuter qurilmalari va ularni vazifalari. 4. Kompyuter tizimlari. Reja: 1. Kompyuterni tuzilishi va turlari. Kompyuter-bu ma'lumotlarni foydali ma'lumotlarga aylantiradigan qurilma. U kirishni foydalanuvchi tomonidan taqdim etilgan ko'rsatmalar to'plamiga muvofiq qayta ishlaydi va mo'ljallangan chiqishni ishlab chiqaradi. Kompyuter atamasi inglizcha "hisoblash" so'zidan olingan bo'lib, "hisoblash uchun" degan ma'noni anglatadi."Hal qilish. Talablar asosida kompyuterlar samarali ishlashga mo'ljallangan. . Kompyuter hajmi va ma'lumotlarni qayta ishlash imkoniyatlariga asoslangan turli xil kompyuter turlari mavjud. Barcha yangi yaratilgan kompyuterlar o'ziga xos xususiyatlar va dizaynlarga ega. Ba'zi kompyuterlar tezkor va katta imkoniyatlarga ega bo'lsa, boshqalari sust. Kompyuterlarning har xil turlari mavjud bo'lsa-da, ularning hajmi va ma'lumotlar bilan ishlash qobiliyatiga qarab biz odatda 5 xil turga bo'lish mumkin. Bulardan: 1. Superkompyuter 2. Asosiy kompyuter 3. Minikompyuter 4. Shaxsiy kompyuter (PC) 5. Ish stantsiyasi Nomidan ko'rinib turibdiki, Superkompyuterlar barcha turdagi kompyuterlar orasida eng katta va eng tezkor kompyuterlardir. Superkompyuterlar katta hajmdagi ma'lumotlarni qayta ishlash va katta hajmdagi hisob-kitoblarni tezda bajarish uchun maxsus qurilgan. Rojer Krey 1976 yilda birinchi superkompyuterni yaratdi.Uning minglab bir-biriga bog'langan protsessorlari bir necha soniya ichida trillionlab ko'rsatmalarni qayta ishlash imkonini beradi. Bunga ob-havo prognozlari, sog'liqni saqlash uskunalari va yadroviy tadqiqotlar kiradi. Superkompyuterlar katta hajmdagi hisob-kitoblarni talab qiladigan yoki juda katta ma'lumotlar bazalarini o'z ichiga olgan ilovalar uchun juda yaxshi. Superkompyuter Asosiy kompyuter Mainframe(asosiy kompyuter) - bu bir vaqtning o'zida yuzlab yoki minglab foydalanuvchilarni qo'llab-quvvatlash uchun yaratilgan ko'p ishlov beruvchi kompyuter. Ushbu turdagi kompyuterlar ikki yoki undan ortiq protsessorga ega va bir vaqtning o'zida ko'plab terminallarda ko'p odamlarni sig'dira oladi. Bitta qurilmada mijozlar statistikasini, aholini ro'yxatga olish ma'lumotlarini va boshqa katta hajmdagi ma'lumotlarni boshqarish ushbu turdagi asosiy funktsiyalardan biridir. Institutlar yoki bo'limlar kabi joylarda mini-kompyuterlar hisob-kitob, buxgalteriya hisobi, savdo firmalari, inventarlarni boshqarish va h.k. kabi vazifalarni bajarish uchun ishlatiladi. MINI KOMPYUTER Minikompyuter - bu mikrokompyuter va asosiy kompyuter o'rtasida joylashgan kompyuter turlari. Mini-kompyuter - o'rta diapazonli kompyuter bo'lib, hajmi, quvvati, tezligi, saqlash hajmi va boshqalar. Ushbu kompyuter ikkita protsessorga ega va bir vaqtning o'zida 200 tagacha odamni qo'llab-quvvatlaydi. Ular institut va bo'limlarda buxgalteriya hisobi bilan bog'liq vazifalarni bajarish uchun keng qo'llaniladi. Shaxsiy kompyuter (PC) Ko'pincha mikrokompyuter sifatida tanilgan shaxsiy kompyuter shaxsiy foydalanish uchun qurilgan umumiy maqsadli kompyuterdir. Shaxsiy kompyuterlar - bu markaziy protsessor, xotira, saqlash joyi, kiritish birligi va chiqarish qurilmasi sifatida mikroprotsessorga ega bo'lgan arzon kompyuterlar. Ushbu kompyuterlar bitta elektron plataga o'rnatilgan kichik sxemalarga ega. Ish stoli, noutbuk va boshqa misollar mavjud. Ish stantsiyasi Ish stantsiyasi kompyuteri odatda texnik yoki ilmiy ilovalar uchun aniq vazifani bajarish uchun ishlatiladigan bir foydalanuvchi kompyuteridir. Ish stantsiyalari tez mikroprotsessor, katta hajmdagi operativ xotira, tarmoq imkoniyatlari, grafik foydalanuvchi interfeysi va yuqori tezlikdagi grafik adapterni o'z ichiga oladi. Ish stantsiyasi kompyuterlari og'ir vazifalarni bajarishga qodir. Animatsiya, SAPR, audio va videolarni tahrirlash, professional o'yinlar va boshqalar. Apple PowerBook G4, MIPS protsessor, SPARC protsessor va boshqa shunga o'xshash kompyuterlar bu turdagi kompyuterlarga misol bo'la oladi.. 1G 2G 3G 4G 5G 1980s 1990s 2000s 2010s Current Analog cell phones allow people to talk to each other Addition of new features like SMS and voicemail Mobile data let users browse the internet LTE offers faster speed and more functionality to mobile devices 5th generation tech allows more connectivity and faster speeds Mobile Networks and 5G Technology As of January 2021 5G Technology Adoption in the World 5G technology adoption continues to rise in more countries and cities. Item 1 Item 2 Item 3 Item 4 Item 5 50 40 30 20 10 0 How 5G is different from 4G LTE Is 5G better than LTE? 5G is a lot faster than the previous Gs, has a lower latency rate, and allows more devices or users to connect to the internet at the same time. The Benefits of 5G Technology INCREASED PRODUCTIVITY SUPPORTED GROWTH FUTURE OF WORK Businesses can move large amounts of data without worrying about network issues that can potentially affect the business. Businesses won't have to worry about adding more connected devices that move essential data to their network. Superior connectivity can further open up businesses to the advantages of remote workers or dispersed teams. 5G can change how businesses work and flourish How 5G Benefits Businesses IMPROVED SERVICES Users can have better experiences with tech and systems, including cloud services, augmented reality, gaming, and more. EFFICIENT ENERGY CONSUMPTION 5G equipment is energy-efficient, so using 5G tech can significantly reduce energy consumption. REMOTE HEALTH CARE Health care providers can access patients' vitals and health data in real-time or perform remote surgery when necessary. 5G can improve people's lives How 5G Benefits Individuals' Daily Lives Concerns about the risks of 5G are unfounded Does 5G technology pose health risks? Experts have expressed that there are no factual bases for claims that say 5G poses risks to people's health though more studies on 5G can be valuable. Consumers also need to be educated more on how 5G works. 5G can change everything, but there needs to be a comprehensive information campaign for businesses and consumers. Internet of Things will explode as connectivity becomes more extensive Artificial Intelligence and Machine Learning technology will also flourish Intelligent Automation will help simplify operations Edge Computing will also gain more interest as businesses adjust to new ways of operating DevOps will be necessary in getting everything to work together efficiently Trends and the Future of Telecommunications The advance of technology is based on making it fit in so that you don't really even notice it, so it's part of everyday life.
