Ethernet Frame

  • [ACSA Training #23] Frame Transmission Process

    Previously, while examining representative Layer 2 technologies such as VLANs and 802.1Q, we also mentioned frames. In a previous post, I also explained Ethernet frames, which correspond to Layer 2 in the OSI model. Therefore, today, I would like to examine how these frames operate during Layer 2 communication using actual examples. First, assuming the same VLAN, several…

  • [ACSA Training #6] Ethernet Frame

    In the last post, we looked at the TCP/IP Stack. We examined the differences between the TCP/IP Stack and the OSI 7-layer model. Today, we will explore Ethernet, which corresponds to Layers 1 and 2 of the OSI 7-layer model. Ethernet is a computer network technology used at Layers 1 and 2 of the OSI model. This standard uses a 6-byte (48-bit) MAC (Media Access Control) address at Layer 2…
