It allows us to define the layout of cables, devices, and routing paths in a network. If we think about it from the perspective of the Internet of Things (IoT), it is defined as the communication of sensors, actuators, and gateways with each other. Some common topologies are invaluable for IoT. In this article, we will discuss these common topologies.<\/span><\/p>\n<p><strong>Point-to-Point Network (PPP):<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">It is possible for two points to communicate directly over PPP, which is one of the data link layer protocols. Thanks to this protocol, user control, data compression, and encrypted communication are possible. The PPP protocol is used in many areas, such as telephone communication, fiber optic cable media, radio communication media, and mobile phones. A Bluetooth connection between a mobile phone and a headset is an example of this topology.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Advantages<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Easy to configure and implement<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Less complex than other types of connections<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is low cost<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Disadvantages<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Provides decentralized management<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Efficiency drops as the network grows<\/span><\/li>\n<\/ul>\n<p><strong>Bus:<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">It is a network topology in which devices are connected to each other with a single cable.

Each station is an element of a ring and the information formed in the ring reaches all stations. Each station receives the information generated in the ring and the destination address. It accepts if the destination address is its own address. Otherwise, the incoming information will be out of the process. The information flow in the ring is unidirectional. In other words, the computers included in the ring are responsible for transmitting the incoming information. However, many ring networks today use two rings and obtain bidirectional information flow. No termination is required.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Advantages<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">All devices on the network have the same privileges<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">New devices added to the network have minimal impact on performance<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Does not need any server<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Disadvantages<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Failure of one device on the network means the entire network crashes<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is quite expensive as the amount of cable used is large.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Star:<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Each device on the network is connected to router equipment such as a switch or hub with regulation capability in the center.
