कमपयुटर परयोग भइरहेको कूनै दुई कषेतरहरूको नाम लेखनुहोस ।
डिजिटल साकषरता भननाले के बुझिनछ ?
सूचना तथा सञचार परविधि भनेको के हो ?
कमपयुटर हारडवेयरलाई उदाहरणसहित वरगीकरण गरनुहोस ।
कमपयुटरको परयोग आज...

4.कमपयुटर हारडवेयर तिन परकारमा विभाजित छ। तिनीहरू हुन :

इनपुट उपकरण ( माउस, किबोरड, सकयानर)

आउटपुट उपकरण ( मनिटर, परिनटर, सपिकर)

परशोधन उपकरण (सि.पी. यु)

सोरेज उपकरण ( सिडि, पेन.डराइभ)

5.धेरै पहिले, कमपयुटरहरू मुखय रूपमा संखयाहरू गणना गरन र शबद परशोधन गरन परयोग गरिनथयो। समय परिवरतन भएसँगै, कमपयूटरले हामीलाई हामरो दैनिक कारयहरूमा मददत गरनको लागि विकसित गरेको छ। आजकल हामी वयकतिगत रमाइलोको लागि आफनो कमपयुटरलाई खेलको लागि परयोग गरेर र इनटरनेटमा जानकारी फेला पारन परयोग गरछौं। हामरो दैनिक जीवनमा कम...
