DES Network. Computer and Network Examples
The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of the electronic data.
The encryption is an important issue for any organization, it allows to safely keep, handle and transmit the sensitive data through the local network, wireless network or the Internet. The encryption applies the key to the plain text and converts it into the ciphertext. The ciphertext at that looks like the set of the random characters.
The key is a mathematical algorithm known only to the sender and the recipient of the message. The applying of the key to the ciphertext will convert it back to the plain text - it is the decryption process.
This diagram was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows how the encryption and access control work together to secure data.

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology.
There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.
