VLANS One of the technologies used to improve network performance is the separation of large broadcast domains into smaller ones. This article describes how to configure, manage, and troubleshoot VLANs and VLAN trunks. It will also explore security considerations and strategies related to VLANs and trunks, and best practices for VLAN design. Networking
MAC Address Complete Guide MAC addresses play a crucial role in the data link layer (Layer 2) of the Open Systems Interconnection (OSI) model. MAC addresses are used to send Ethernet frames between two stations in the same local area network. Each station has a unique MAC address that is used to identify who is the sender (source mac address) and who the receiver (destination mac address) is. Networking
IP Packet Structure IPv4 is the most widely used version of the Internet Protocol on the internet, and it is responsible for the rules of data transmission between the computing machines. Networking
Ethernet Frame Header In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload. Networking
Maximum Transmission Unit (MTU) and the Maximum Segment Size (MSS) The maximum segment size (MSS) is a parameter of the Options field of the TCP header that specifies the largest amount of data, specified in bytes, that a computer or communications device can receive in a single TCP segment. It does not count the TCP header or the IP header. Networking
