Abstract
- Stands for Carrier Sense Multiple Access
- Basically multiple Host share the same Carrier to communicate
Challenges
Computers need to know if it should process the incoming data
- When one computer sends a piece of data to another computer, the other computers sharing the same Carrier will also receive the data
- This can be solved using MAC Address. The computer only processes the data when the recipient address matches it’s MAC address in the data
Collision among computers
Terminologies
Carrier
- Refers to any shared transmission medium
- Copper wire in the case of Ethernet
- Air carrying radio waves for Wi-Fi
Multiple Access
- Refers to many computers can send Data over the same Carrier simultaneously
Collision
- Happens more than one computer on the Carrier sand Data at the same time
- Data in the Carrier will get messed up, requires a re-send
- Can be detected by listening on the signals on the Carrier
