  🔸 1. Pentium 1, 2, 3, 4 ·          🕰 ️ Old generation processors from Intel ·          ⚙️ Single core hote thay (sirf 1 kaam ek time pe achhe se karte) ·          🖥 ️ Used in: Windows 95/98/XP time ke computers ·          ❌ Slow processing speed, modern software ke liye weak 🔸 2. Dual Core ·          ⚙️ 2 cores (yaani 2 brain) — ek time pe 2 tasks handle kar sakta hai ·          🧠 Better multi-tasking than Pentium ·          🖥 ️ Used in: Early Windows 7 laptops/PCs ·          ✅ Decent for light use (browsing, MS Office, movies) 🔸 3. Core2Duo ·          💡 Intel ka improved ...

  This is Related for  computer power supply (SMPS) 🔌 1. 20+4 Pin Connector 🧠 Use: Motherboard ko power dene ke liye 📍 Details: Yeh main connector hota hai jo motherboard me lagta hai. 20 pin old motherboards ke liye, aur extra 4 pin new boards ke liye hote hain. 🔌 2. PCI-E Connector 🎮 Use: Graphic card ko power dene ke liye 📍 Details: High power graphic cards (like NVIDIA/AMD) ko extra power chahiye hoti hai, jo yeh connector deta hai. 🔌 3. SATA Power Connector 💾 Use: SSD, HDD, DVD drive 📍 Details: SATA devices (jaise SSD, HDD, CD/DVD drive) ko power dene ke liye use hota hai. 🔌 4. Floppy Connector 📼 Use: Old floppy disk drives ke liye 📍 Details: Ab use nahi hota, sirf purane PCs me milta hai. 🔌 5. P4 MB Connector (4-pin CPU Power) 🧠 Use: Processor ko power dena 📍 Details: Yeh motherboard ke CPU socket ke paas lagta hai, processor ko extra power deta hai. 🔌 6. 4-Pin Molex Connector...

  Motherboard Diagram 🔹 1. CPU Socket 🧠 Yahan processor (CPU) lagta hai. 👉 Har motherboard ka socket type alag hota hai (Intel ya AMD). 🔹 2. CPU Heat Sink Mounts 🌬 ️ Yahan fan ya heat sink lagta hai processor ke upar taake wo thanda rahe. 🔹 3. Power Connector (20+4 pin) ⚡ Power Supply yahan connect hoti hai motherboard ko power dene ke liye. 🔹 4. DRAM Memory Slots (RAM Slots) 💾 Yahan RAM lagti hai. Usually 2 ya 4 slots hote hain. 🔹 5. Hard Drive Slots (SATA connectors) 📦 Yahan HDD ya SSD connect hote hain data store karne ke liye. 🔹 6. ROM (BIOS/UEFI chip) 🧬 Yeh chip motherboard ki basic settings aur boot instructions store karti hai. 🔹 7. Northbridge Chip 📶 Fast communication karta hai CPU, RAM aur graphics ke beech. (Ab naye boards me directly CPU me hota hai) 🔹 8. Southbridge Chip 🔌 Control karta hai slow devices jaise USB, audio, LAN ports, etc. 🔹 9. PCI Slot...

  ✅ Best PoE Injector: Active PoE Injector hi best aur safe hota hai. Wajah neeche easy words me: 🔌 Active PoE vs Passive PoE – Simple Comparison: Feature 🔋 Active PoE (802.3af/at/bt) ⚡ Passive PoE Voltage Control Device se handshake karta hai No control – direct voltage Auto Power Match Device jitni power mange, utni deta hai Fixed voltage deta hai (24V/48V/52V) Safe for Devices ✅ Safe – overvoltage nahi deta ❌ Risky – device jal sakti hai Standard Follows 802.3af (15.4W), 802.3at (30W), bt (60–90W) No standard Compatibility Smart – har PoE device ke sath kaam karta hai Sirf passive PoE supported devices ke sath 🔧 Toh best kya hai? ➡️ Active PoE Injector hi best hai kyunki: Wo sirf usi device ko power deta hai jo PoE support karti ho Jitni power chahiye, utni hi deta hai Device ko damage hone se bachata hai
