Study Notes
Ethernet
- Ethernet is the standard for connecting devices in wired LANs and WANs.
- Devices communicate using a protocol (a set of rules).
- Ethernet specifies how data is formatted and transmitted for recognition.
- Cables carry the data physically.
- Ethernet is typically more stable and secure than wireless.
Why Use Ethernet?
- Initially popular due to lower cost compared to other technologies (like IBM's token ring).
- Evolved to offer higher performance.
- Initially used coaxial cables, connecting devices via hubs in daisy chain or star topology.
- Now commonly uses twisted-pair or fiber optic cables.
Ethernet Advantages & Disadvantages
-
Advantages:*
-
Relatively inexpensive
-
Backward compatible
-
Noise resistant
-
Good data transfer quality
-
Fast speeds
-
Reliable
-
Supports data security (with firewalls)
-
Disadvantages:*
-
Best for shorter, smaller networks
-
Limited mobility
-
Longer cables can experience crosstalk
-
Not ideal for real-time/interactive applications
-
Troubleshooting can be difficult.
How Ethernet Works
- IEEE 802.3 standards dictate the protocol, covering both physical connection and data transmission.
- Ethernet uses "packets" and "frames" for transmission.
- Frames contain the data payload and MAC addresses of sender and receiver.
- Devices require a network interface card (NIC).
Network Interface Card (NIC)
- A NIC is a hardware component essential for network connection.
- It's a circuit board installed in a computer.
- Also known as network interface controller, network adapter, or LAN adapter.
