A |
computer is an electronic device that accepts
data as input, processes it according to given instructions, stores it for
future use, and produces meaningful information as output. It is designed to
perform calculations, solve problems, and manage data quickly, accurately, and
efficiently.
·
The word computer is derived
from the Latin word computare.
·
Some people also say it comes from compute.
·
Both computare and compute
mean to calculate.
·
In Hindi, both translate to गणना करना
(to calculate).
कंप्यूटर के कार्य करने के तीन (Step) चरण होते हैं:-
·
·
Process – इसमें कंप्यूटर निर्देश को प्रोसेस करता है और डेटा को सूचना (Information) में कन्वर्ट करने का कार्य करता है।

✅ COMPUTER – Full Form (For Learning Purpose) C - Commonly (आम तौर पर) O - Operated (संचालित) M - Machine (मशीन) P - Particularly (विशेष रूप से) U - Used in (में प्रयुक्त) T - Technical (तकनीकी) E - Educational (शैक्षिक) R - Research (अनुसंधान) So, this stands for: |
·
Storage- CPU द्वारा प्रोसेस किए गए रिज़ल्ट को सेव करता है।
✅ Main parts of
a computer:
v
Input devices –
Like keyboard, mouse, scanner (used to enter data).
v
Central Processing Unit (CPU)
– The brain of the computer that processes information
v
Memory/Storage –
Stores data and programs (RAM, hard drive, etc.)
v
Output devices –
Like monitor, printer (used to results).
v
Software – Programs
that tell the computer do.
Features of a
Computer / कंप्यूटर की विशेषताएँ
1. Speed (गति) A computer works much faster
compared to humans. It can complete millions of tasks in a second. Its speed is
measured in Hertz (Hz).
कंप्यूटर इंसान की तुलना में बहुत
तेज़ कार्य करता है। यह एक सेकंड में लाखों कार्य पूरा कर सकता है। इसकी गति
हर्ट्ज़ (Hz) में मापी जाती है।
2. Accuracy (शुद्धता)
A
computer performs tasks without errors. It is more accurate than humans.
कंप्यूटर बिना गलती के कार्य करता
है। मनुष्य की तुलना में इसकी शुद्धता अधिक होती है।
3. Memory (स्मृति)
A
computer has a large memory capacity. It can store data and retrieve it when
needed.
कंप्यूटर में बहुत बड़ी स्मृति होती
है। यह डेटा को संग्रहीत करके ज़रूरत पड़ने पर तुरंत उपयोग कर सकता है।
4. Diligence (परिश्रम)
A
computer can work continuously without getting tired, unlike humans who need
rest.
कंप्यूटर बिना थके लगातार काम कर
सकता है। जबकि मनुष्य को विश्राम की आवश्यकता होती है।
5. Automation (स्वचालित)
A
computer performs tasks automatically. Once instructed, it continues to work
without further human assistance.
कंप्यूटर अपने कार्य खुद से पूरा
करता है। एक बार आदेश मिलने के बाद यह बिना किसी मदद के काम करता रहता है।
✅कंप्यूटर की कमज़ोरियाँ (Weaknesses of a Computer)
No
IQ (Intelligence quotient)
A
computer does not have the ability to think and understand like a human. That
is why a computer is dependent on humans.
कंप्यूटर के अंदर मानव की तरह सोचने
और समझने की शक्ति नहीं होती है। इसलिए कंप्यूटर मानव का गुलाम होता है।
No Feeling
A
computer does not have feelings like a human being.
कंप्यूटर के पास मानव की तरह कोई
भावना (feeling) नहीं होती है।
