Computer Networking: Journal 7

This week in my computer networking class, we further learned about the link layer. which encompasses broadcast channels and point-to-point communication. What I found interesting is how even though the link later is implemented in hardware, the link layer also involves many software components to make it work. Also, the link layers main purpose is to move datagrams between neighboring nodes, offering additional services such as framing, link access, reliable delivery, and error detection/correction.  Multiple access protocols are employed for regulating transmission on shared broadcast channels, categorized as channel partitioning, random access, and taking-turns protocols. The Address Resolution Protocol (ARP) is responsible for translating IP addresses to MAC addresses at the link layer. All in all, this was an interesting week further exploring and expanding the link layer.
