Hardware = touchable, Software = instructions.💡 Smallest info unit: bit (0/1). Byte = 8 bits. ⚙️ CPU (Brain)CPU = Central Processing Unit. Consists of ALU (arithmetic/logic), Control Unit, Registers. Main job: execute program instructions & process data. 🔌 Motherboard & MicroprocessorMotherboard = main circuit board. Biggest microprocessor company: Intel. IBM = "Big Blue". ENIAC (first electronic computer, 1946). 📊 Data → InformationData = raw facts; Information = processed meaningful data. Output devices show processed results (monitor, printer). 🧠 Pioneers & HistoryGeorge Boole → symbolic logic. Charles Babbage → Analytical Engine. MANIAC (1952 H-bomb project). 📝 30 Important Computer Questions (KVS Exam) 📍 KVS TGT/PRT/PGT Exam Pattern 2025 | Computer Literacy Section | Based on previous year papers & official syllabus 🔁 Tap 'Show Answer' to check solution.
