CH 4 Data Link Sublayers

MAC sublayer communicates with what?

Ethernet LAN technology to send and receive frames over copper or fiber-optic cable. The MAC sublayer also communicates with wireless technologies such as Wi-Fi and Bluetooth to send and receive frames wirelessly.

The data link layer is divided into two sublayers:

Logical Link Control (LLC) Media Access Control (MAC)

Media Access Control (MAC)

This lower sublayer defines the media access processes performed by the hardware. It provides data link layer addressing and access to various network technologies.

Logical Link Control (LLC)

This upper sublayer communicates with the network layer. It places information in the frame that identifies which network layer protocol is being used for the frame. This information allows multiple Layer 3 protocols, such as IPv4 and IPv6, to utilize the same network interface and media.

while the MAC does what?

allows various network access technologies.

The LLC communicates with the ?
