LAN - Local Area Network, digital devices interacting over a shared communication medium
###Ethernet
Ethernet cable: 4 twisted pairs
connecting computer with cables in a LAN environment
wifi and ethernet speak the same language IP protocol and can exchange frames(organised collection of data)
###Wi-FI

Example output
## **Network Technology**
### **LAN (Local Area Network)**
- Definition: Digital devices interacting over a shared communication medium.
- Ethernet and Wi-Fi are commonly used in LAN environments.
### **Ethernet**
- Definition: A network technology that uses cables to connect computers in a LAN.
- Ethernet cable: Consists of 4 twisted pairs.
- Ethernet and Wi-Fi use the same IP protocol and can exchange frames (organized collection of data).
- Different cable types: UTP, Cat 5e, Cat 6, Cat 6a, Optical Fiber.
- Transmission problems: Attenuation, Delay/Latency, Thermal/Intermodulation Noise, Crosstalk.
- PoE (Power over Ethernet): Power and data transmission over the same cable.
### **Wi-Fi**
- 802.11 standard is used for Wi-Fi networks.
- MIMO (Multiple Input Multiple Output) technology improves wireless performance.
- Wi-Fi allows mobile devices to connect without physical attachment.
- WPA2 (Wi-Fi Protected Access 2) provides security for Wi-Fi networks.
### **Bluetooth**
- Bluetooth uses the 802.15 standard for short-range wireless communication.
### **OSI Model vs TCP/IP Model**
- OSI Model: Consists of 7 layers (Physical, Access, Network, OS, Transport, Session, Application).
- TCP/IP Model: Consists of 4 layers (Network Interface, Internet, Transport, Application).
