| 6 |  🔧 AMALIY TOPSHIRIQ
Kompyuteringizdagi PSU modelini toping.
Agar desktop kompyuter bo‘lsa, PSU korpusidagi yorliqdan:
📌 Model
📌 Umumiy quvvat (W)
📌 Ishlab chiqaruvchi
ma’lumotlarini yozib oling.
Masalan:
Model: ____
Power: __ W
Brand: ____
⚠️ PSU'ni ochmang. Ichki qismlarida xavfli kuchlanish bo‘lishi mumkin.

| 8 |  💡 BUNI BILASIZMI?
PSU'larda turli xil himoya funksiyalari bo‘lishi mumkin:
🛡️ OVP — ortiqcha kuchlanishdan himoya
🛡️ OCP — ortiqcha tokdan himoya
🛡️ OPP — ortiqcha quvvat yuklamasidan himoya
🛡️ SCP — qisqa tutashuvdan himoya
📌 Sifatli PSU tanlash kompyuter barqarorligi uchun juda muhim.
@Tarmoq_Tizim_admin | 120 |
| 9 |  ⚡ PSU'DAGI “WATT” NIMA?
PSU ustida masalan:
450W
550W
650W
750W
kabi raqamlarni ko‘rishingiz mumkin.
Watt (W) — quvvat o‘lchov birligi.
Masalan:
🟢 500W PSU → nominal quvvati 500 watt bo‘lgan quvvat manbai.
Lekin faqat watt soniga qarab PSU tanlash to‘g‘ri emas. | 118 |

📌 PSU kompyuterning barcha qismlariga kerakli quvvatni yetkazib beradi. | 136 |
| 11 |  ⚡ PSU NIMA?
PSU (Power Supply Unit) — kompyuterning quvvat manbai.
Oddiy qilib:
👉 PSU — elektr energiyasini kompyuter qismlari ishlata oladigan quvvatga aylantirib, ularni kerakli kuchlanish bilan ta’minlaydi. | 148 |
| 12 | BGP FSM (Finite State Machine) holatlaridan qaysi biri qo‘shnilar o‘rtasida sessiya o‘rnatilganini va UPDATE xabarlari almashilayotganini bildiradi? | 150 |

🧠 CPU → hisoblaydi
⚡ RAM → vaqtinchalik ma’lumotlar bilan ishlaydi
💾 SSD/HDD → ma’lumotlarni saqlaydi
🎮 GPU → grafikani qayta ishlaydi
🖥️ Motherboard → komponentlarni bog‘laydi

| 15 |  🔧 AMALIY TOPSHIRIQ
Agar desktop kompyuteringiz bo‘lsa, korpusni ochmasdan ham motherboard modelini aniqlash mumkin.
💻 Win + R
→ msinfo32
→ Enter
System Model yoki BaseBoard ma’lumotlarini tekshiring.
📌 Motherboard modelini topishga harakat qiling.
Keyin internetdan uning:
nechta RAM sloti borligi;
nechta M.2 sloti borligi;
qaysi CPU'larni qo‘llab-quvvatlashi
haqida ma’lumot izlang.

| 17 | Cisco qurilmalarida eBGP (External BGP) protokolining standart Administrative Distance (AD) qiymati nechaga teng? | 180 |
| 18 |  💡 BUNI BILASIZMI?
Motherboard'larning o‘lchamlari ham turlicha bo‘ladi.
📏 ATX
📏 Micro-ATX
📏 Mini-ITX
Shuning uchun kompyuter yig‘ishda faqat CPU va RAM emas, korpus va motherboard o‘lchamlari ham mos bo‘lishi kerak.

| 19 |  🧩 MOTHERBOARD'DAGI MUHIM JOYLAR
1️⃣ CPU Socket
🧠 Protsessor shu joyga o‘rnatiladi.
2️⃣ RAM Slotlar
⚡ Operativ xotira modullari ulanadi.
3️⃣ PCIe Slot
🎮 Videokarta va boshqa kengaytirish kartalari ulanadi.
4️⃣ M.2 Slot
💾 M.2 SSD o‘rnatilishi mumkin.
5️⃣ SATA Portlar
💾 SATA SSD yoki HDD ulanishi mumkin.
6️⃣ Power Connectorlar
🔌 PSU’dan motherboard’ga elektr quvvati keladi.
