What is hardware ?
Computer hardware refer to the physical tangible parts of a computer system that you can see and touch,such as the central processing unit (cpu), memory (ram), storage drives, keyboard, mouse,and monitor. These components include the mechanical, electronic, and electrical parts that make up the computer and are necessary for it to function by accepting, processing and displaying Data. Hardware works in conjunction with software, which provides the instructions that the hardware follows to perform tasks
कंप्यूटर हार्डवेयर क्या है ?
कंप्यूटर सिस्टम के भौतिक मूर्त भागों को संदर्भित करता है जिसे आप देख सकते हैं और स्पर्श कर सकते हैं जैसे केंद्रीय प्रसंस्करण इकाई सीपीयू मेमोरी Ram स्टोरेज ड्राइव कीबोर्ड माउस और मॉनिटर इन घटकों में मैकेनिकल इलेक्ट्रॉनिक और इलेक्ट्रिकल पार्ट्स शामिल हैं
