4 days ago · When the switch receives a packet to one of the Ethernet ports, it uses the MAC address to specify which port to send the data packet to, then sends the data to the device. Once a switch has sent a packet along a route one time, it begins to maintain a table and a list of MAC addresses that connect to that specific port.
5 days ago · Message switching and packet switching are two ways to send data across networks. Message switching sends entire messages as one unit, like a complete letter. Packet switching breaks data into smaller packets, sending each separately, like mailing a letter in pieces.

3 days ago · 7 Data networks and packet switching. You have seen that data packets are responsible for transferring data across networks, and require IP addresses to do so. The box below describes in more detail how a PC uses packets to retrieve a webpage (without considering the action of NAT).
3 days ago · Normally, TCP waits for 200 ms for a full packet of data to send (Nagle's Algorithm tries to group small messages into a single packet). This wait creates small, but potentially serious delays if repeated constantly during a file transfer.
5 days ago · This process is called packet switching, and it allows multiple devices on a network to communicate simultaneously without interfering with each other. There are various types of switches, including unmanaged switches, managed switches, and Layer 3 switches.
5 days ago · Packet switching divides transmitted data into smaller packets that travel independently across the network. Each packet contains part of the data plus destination information, allowing for efficient and flexible transfer. Packets adapt to network traffic by finding the best routes.
2 days ago · Once the router has determined that the packet needs to be forwarded from G0/1, it has three tasks: switch the packet to interface G0/1; perform Network Address Translation (NAT) on the source address of the packet; encapsulate the packet in an appropriately addressed frame.
