🔧 8 Essential Network Devices 🤩
Want to become a networking expert? Start with these core devices:

✅ Router – Connects multiple networks & finds the best route for data
✅ Switch – Connects devices in a LAN using MAC addresses for efficient communication
✅ Hub – Outdated device that sends data to all connected ports (less secure)
✅ Access Point – Extends wired networks wirelessly (Wi-Fi connectivity)
✅ Firewall – Monitors, filters & protects network traffic from threats
✅ Modem – Connects your home/office network to your ISP
✅ Gateway – Acts as a translator between different network protocols
✅ Load Balancer – Distributes incoming traffic across multiple servers to prevent overload

📡 These devices are the foundation of every network.
📘 Learn them. Master them. Level up your IT journey.

🔹Types of Memory

🔹Primary Memory (Main Memory
1. RAM (Random Access Memory) Temporary, fast, volatile memory used during processing
2. ROM (Read-Only Memory) Permanent, non-volatile memory storing firmware

🔸 Secondary Memory (Storage)
3. Hard Disk Drive (HDD) Magnetic storage for large files
4. Solid State Drive (SSD)Faster, durable storage
5. Optical Disc CDs/DVDs for reading/writing data
6. Flash Drives Portable USB storage

1. SRAM (Static RAM)
Faster, expensive, used in cache memory

2. DRAM (Dynamic RAM)
🔴Slower, cheaper, needs constant refreshing
🔵Common in main system memory

🔸 DRAM Variants:

3. SDRAM (Synchronous DRAM)
🔴Synchronized with system clock
🔵Faster than regular DRAM

4. DDR (Double Data Rate) SDRAM
⚫ Transfers data twice per clock cycle

5. DDR2
⚫Faster and more efficient than DDR

6. DDR3
⚫Lower power use, better speed than DDR2

7. DDR4
⚫High-speed, low voltage, current standard

8. DDR5
⚫Latest, faster, higher capacity & bandwidth

🔹 Other RAM Types:

9. VRAM (Video RAM)
⚫ Used in graphics cards for video rendering

10. ECC RAM (Error-Correcting Code RAM)
🔴 Detects and corrects memory errors
🔵Used in servers and critical systems

11. LPDDR (Low Power DDR)
🔴Mobile version of DDR used in smartphones

🔌 Types of Ethernet Cables (Cat 1 to Cat 8.2)

Cat 1–4: Old, used for phones & early networks (now obsolete).

Cat 5: 100 Mbps – For basic networking.

Cat 5e: 1 Gbps – Enhanced for Gigabit speeds.

Cat 6: 1–10 Gbps (short range).

Cat 6A: 10 Gbps – For modern high-speed setups.

Cat 7/7A: 10 Gbps – Better shielding & noise resistance.

Cat 8/8.2: 25–40 Gbps – Ultra-fast, for data centers.

Faster internet isn’t just about your plan your cable matters too! ⚡
Which Cat cable do you use at home or office?
