Analog Computer
  • Result ko analog signals me express karta hai.
  • Pressure, temperature, length jaise physical quantities ko measure karne me use.
  • Scientific aur engineering field me zyada use.
  • Example: Thermometer.
Digital Computer
  • Number system / binary numbers par work karta hai.
  • Source ke anusaar, correct data dene par correct result deta hai.
  • Examples: Calculator, Digital Watch.
Hybrid Computer
  • Digital aur analog dono form me result express karta hai.
  • Example: Petrol pump par oil/fuel dispensing machine.
⚡ One-Line Difference
Analog = continuous physical quantities • Digital = binary/number system • Hybrid = Analog + Digital
🚀 Super Computer

  • Speed Unit: FLOPS — source expands it as “Floting Point Operation Per Second”.
  • Super computer banane wali company: C-DAC — “Centre for Development Advance Computing” as printed in source.
  • भारत का सबसे पहला सुपर कम्प्यूटर: PARAM 8000.
  • Source me duniya ka sabse tez computer: Fortior.
  • Source me भारत का वर्तमान सबसे तेज सुपर कम्प्यूटर: Airawat — 13170 Teraflop.
  • Use: scientific purposes.
  • Source line: Cary Ist duniya ka pehla super computer.
📘 Source Fidelity
Names, spellings aur “current fastest” jaise statements ko PDF me jis tarah diya gaya hai, usi tarah preserve kiya gaya hai; is chapter me outside web-verification add nahi ki gayi.
⚠ Exam Trap
PARAM 8000 = India ka first super computer (source). Airawat = source ka current-fastest India fact. FLOPS = speed unit. In teen facts ko alag rakho.
🖥️ Size-Based Computers — Visual Gallery
Mainframe computer image from source PDF
Mainframe Computer
Mini computer se zyada processing power; large business data processing and scientific work.
Mini computer image from source PDF
Mini Computer
Large companies, traffic control, banks; source calls them reliable.
Micro computer image from source PDF
Micro Computer
Microprocessor-based PC class; desktop, laptop and palmtop listed in source.
Mainframe Computer
  • Processing power mini computers se bahut zyada.
  • Scientific work aur very large business companies ke data processing me use.
  • Ek saath bahut se alag-alag tasks kar sakta hai.
Mini Computer
  • Large companies me use.
  • Source ke anusaar reliable.
  • Traffic control, banks aur big companies me use.
Micro Computer

Core Facts

Microprocessor ka use. Speed ke liye Mega Hertz diya gaya hai. Ye PC computers hote hain. Development year source me 1970 hai.

Source Configuration Fact

Source me most successful micro computer PC × T likha hai; Intel 8088 microprocessor, 64 KB RAM aur 10 MB hard disk ka mention hai.

⚛️ Quantum Computer — New Era in Computer
  • Source ise “new era” computer ke roop me present karta hai.
  • Physics ke principles par work karta hai.
  • Source statement: speed PC se 100 million times faster hogi.
🧩 Surface Computer
  • Source ke anusaar iske use ke liye traditional monitor, keyboard aur CPU ki आवश्यकता नहीं होती.

⚠ High-Confusion Pairs
  • Analog measures/represents physical quantities; Digital works on binary/number system.
  • Hybrid combines analog + digital characteristics.
  • Super and Mainframe are both powerful, but source separately treats supercomputer for scientific purposes and mainframe for large-scale processing/multitasking.
  • Mini ≠ Micro: micro uses a microprocessor and is listed as PC category.
