Based on its fundamental form, computer networks are divided into two types, namely distance and transmission. The following are two types of classification of computer network types based on their transmission.
1. Broadcast
A broadcast network is a single communication channel that is used jointly by several devices (devices) that are connected to the same network. Packets are small messages sent by one machine to another. The address field contains information about to whom the package will be sent. If the packet is addressed to him, it will be processed immediately. If the packet is sent to another machine, the machine will automatically ignore it.
2. Point-to-Point
The second type is a point-to-point network composed of several individual paired connections, from one device to another. To be able to send a packet to the destination address, it is necessary to pass through several intermediary machines. So, it will often pass through many routes that may differ in distance. Therefore, the route algorithm plays an important role in this network.
Computer network topology
1. Bus
Bus topology is a topology that has a single cable that each workstation and server are connected to each other. The advantage of the bus topology itself is that when developing new networks and workstations, it does not interfere with other workstations. The disadvantage is that when the cable is damaged or broken, it will experience disruption to the entire network.
2. Ring
Ring or ring topology is a topology that is formed when all devices are connected, so that it resembles a ring or circular pattern. So, each workstation will receive information from one device to another. The advantage of the ring topology is that there will be no collision or collision between data. Meanwhile, the disadvantage of this topology is that if one of the nodes experiences a problem, the entire network will experience interference.
3. Star
Star topology is a topology in which each workstation has a path that is connected directly through a server or hub. The advantage of this topology is that if one of the workstations experiences a problem, not all networks will experience the same thing. Because, each workstation has its own line or cable. The disadvantage of the star topology is that it requires a large cost, because it requires a lot of cable resources.
4. Tree
Tree topology is a combination of star and bus topology. This network topology resembles the shape of a tree root, which can be said to be only a hub device that is directly connected to the tree bus. And each hub serves as the root of the tree. The advantages and disadvantages of a tree topology are the same as bus and star topologies. However, using this tree network (hybrid), supports a better network expansion.
5. Mesh
Mesh topology is often used when there is a condition where there is no absolute disconnected communication link between nodes in a computer network. Devices will be directly connected as long as they are on the same network. The advantages of the mesh topology are faster communication between computers, and more secure security. The disadvantage of the mesh topology is that it requires a greater cost in providing cables.
