Chapter 12, Problem 12RQ
Explanation of Solution
Examples of layer 2 LAN that works at Layer 1:
- Ethernet
- USB
- Wi-Fi
- Bluetooth
Ethernet:
- Ethernet is a network technology used to connect computers in limited area.
- Several wiring and signaling variants used in Ethernet are called standard Ethernet.
- A Standard Ethernet uses the bus topology.
- Ethernet bus topology is easy to install, inexpensive, and requires less cable for connection
USB:
- One type of flash storage device is the Universal Serial Bus (USB) flash drive.
- It is easy to work with Personal Computer (PC), and it does not require any device driver to install the device.
- It is also called as memory sticks, thumb drives or jump drives.
Wi-Fi:
- Wi-Fi (Wireless Fidelity) is the wireless communication technology that is capable to support high speed internet and network connections...
