what is computer/कम्प्यूटर क्या है

कम्प्यूटर क्या है? कंप्यूटर एक उपकरण है जो इनपुट को स्वीकार करता है, इसे संसाधित करता है, यदि आवश्यक हो तो डेटा संग्रहीत करता है और उपयोगकर्ता की आवश्यकता के अनुसार वांछित आउटपुट देता है। कंप्यूटर शब्द का उपयोग इलेक्ट्रॉनिक और इलेक्ट्रोमैकेनिकल (पार्ट इलेक्ट्रॉनिक और पार्ट मैकेनिकल) घटकों के संयोजन से बने डिवाइस का वर्णन करने के लिए किया जाता है। अपने आप में, एक कंप्यूटर में कोई खुफिया नहीं है और इसे हार्डवेयर के रूप में संदर्भित किया जाता है। सामान्य तौर पर कंप्यूटर निम्नलिखित कार्य करता है। 1. उपयोगकर्ता आपूर्ति डेटा और निर्देशों को स्वीकार करें। 2. दिए गए निर्देश के अनुसार उच्च गति पर दी गई बड़ी मात्रा में जानकारी संग्रहीत करता है। 3. दिए गए निर्देश के अनुसार उच्च गति पर दी गई जानकारी को संसाधित करें। 4. उपयोगकर्ता विनिर्देशों के अनुसार परिणाम आउटपुट करें 5. बहुत तेज दर पर केबल के माध्यम से डाटा, इमेज, साउंड और ग्राफिक्स ट्रांसफर करता है दूसरे शब्दों में, हम कंप्यूटर को आपूर्ति करते हैं; संसाधित होने के लिए डेटा और निर्देश डेटा के साथ प्रक्रिया। कंप्यूटर डेटा और न...
