What is an Ethernet frame?

Ethernet frame is a way to organize parts of data for transmission via a computer network. The frame is one of the key elements of the Ethernet system, one of the most popular types of the local network. It consists of three elements: a pair of addresses, data itself and errors for checking errors. Ethernet is commonly used for local networks where computers are connected in the same physical location as the household or office building. The Ethernet name is also used for a specific type of physical connection, namely Cat5 cable with RJ45 plug. This is better known as Ethernet Cable and turns on to virtually all computers and other network devices. This means that transferred files or commands are divided into small collections. Each of these collections is then connected and sent as one piece, with "packets" re -assembled at the other end. The idea is that if there is a problem with the transfer of one particular packet, the rest of the data can continue to be transmitted while computers are trying to solve the problem.

The

packet contains three types of data organized within Ethernet. The first type of data in each packet consists of address boxes that identify specific computers that send and receive data. This ensures that it does not end on the wrong machine in the network.

The second type is the actual data that is transmitted. Each packet contains 64 to 1,500 data bytes. This means that the file as small as 1 MB can be divided into thousands or more packets.

The third type of data within Ethernet is the error check field. This includes the creation of a code number that varies depending on the length and content of the data contained in the packet. When the recipient's computer gets a packet, it uses the same system to create your own code number from the data it receives. If two code numbers do not match, the machine will know that some data are either missing or incorrect, and will require that it is sent again.

one way to understandAs different elements of the Ethernet framework work in a data packet, it is to imagine a physical packet sent by mail. The address fields are equivalent to the delivery and address of the sender written on the packet. The data itself is equivalent to the contents of the packet. The error check field is the equivalent list of content located inside the packet so that the recipient can check everything.
