Kompyuter, dastur deb ataladigan ko'rsatmalar to'plamining nazorati ostida matematik hisoblar yoki elektron aloqa kabi vazifalarni bajaradigan mashina. Dasturlar odatda kompyuterda joylashgan bo'lib, kompyuterning elektronikasi tomonidan olinadi va qayta ishlanadi va dastur natijalari saqlanadi yoki video displey monitorlari yoki printerlar kabi chiqish qurilmalariga yo'naltiriladi. Kompyuterlar turli xil ishlarni ishonchlilik, aniqlik va tezlik bilan bajarish uchun ishlatiladi. Odamlar kompyuterdan turli xil usullarda foydalanadilar. Biznesda kompyuterlar shtrix kodlar va skanerlar yordamida inventarlarni kuzatib boradi, mijozlarning kredit holatini tekshiradi va pul mablag'larini elektron tarzda o'tkazadi. Uylarda ko'pgina jihozlarning elektron sxemasiga o'rnatilgan kichik kompyuterlar xona ichidagi haroratni nazorat qiladi, uy xavfsizlik tizimlarini boshqaradi, vaqtni aytadi va videokassetalarni yoqadi va o'chiradi. Avtomobillardagi kompyuterlar yoqilg'i oqimini tartibga soladi va shu bilan gazning yurishini oshiradi. Kompyuterlar, shuningdek, stereo tizimlarda raqamli tovush yoki raqamli kodlangan lazer diskidan kompyuter animatsion funksiyalarini yaratib, ko'ngil ochishadi. Kompyuter dasturlari yoki ilovalari hammaga yordam berish uchun mavjud ta'lim darajasi, oddiy qo'shish yoki jumlalar tuzishni o'rgatadigan dasturlardan tortib, ilg'or hisob-kitoblarni o'rgatuvchi dasturlargacha. O'qituvchilar kompyuterdan baholarni kuzatish va eslatma tayyorlash uchun foydalanadilar; kompyuter tomonidan boshqariladigan proyeksiya birliklari bilan ular ma'ruzalariga grafik, tovush va animatsiya qo'shishlari mumkin. Kompyuterlar ilmiy tadqiqotlarda matematik muammolarni hal qilish, murakkab ma'lumotlarni ko'rsatish yoki qurish uchun juda qimmat yoki amaliy bo'lmagan tizimlarni modellashtirish, masalan, kosmik kemalarning keyingi avlodi atrofida havo oqimini sinash uchun keng qo'llaniladi. Harbiylar xabarlarni kodlash va ochish, shuningdek, xodimlar va ta'minotni kuzatib borish uchun murakkab aloqalarda kompyuterlardan foydalanadi. What is a computer? A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos. Before we talk about different types of computers, let's talk about two things all computers have common: hardware and software. Hardware is any part of your computer that has a physical structure, such as the keyboard or mouse. Software is any set of instructions that tells the hardware what to do and how to do it. Examples of software include web browsers, games, and word processors. Everything you do on your computer will rely on both hardware and software. For example, right now you may be viewing this lesson in a web browser (software) and using your mouse (hardware) to click from page to page. As you learn about different types of computers, ask yourself about the differences in their hardware. As you progress through this tutorial, you'll see that different types of computers also often use different types of software. Download 17.83 Kb. Do'stlaringiz bilan baham: |
