3. NOTES
3.1. Types of Network Topologies
3.1.1. Mesh: A type of network topology that has a physical connection to every other node
3.1.1.1. Provides the highest level of redundancy
3.1.2. Star Toplogy: A type of network topology in which each device is connected to a central node (or central switching device) called a hub
3.1.2.1. Hub-and-Spoke can be included as Star Toplogy
3.1.2.1.1. Used in contemporary Ethernet LANs.
3.1.3. Bus Topology: A type of network topology in which all devices are connected to a single cable called a "bus."
3.1.3.1. Features
3.1.3.1.1. Main network cable becomes a single point of failure
3.1.3.1.2. All network nodes connect to a single central cable
3.1.3.1.3. A terminator at each end of the network cable prevents collision caused by signal rebounce
3.1.4. Ring Topology: A type of network configuration where devices are connected in a circular manner, forming a closed loop.
3.1.4.1. Features
3.1.4.1.1. Network nodes are daisy-chained in a closed loop
3.1.4.1.2. Data is passed through each intermediate node until the receiver node is reached
3.1.4.1.3. Each network node connects to exactly two other nodes
3.1.5. Hybrid Network Topology: A type of network topology that combines two or more differing standard network topologies
3.1.5.1. P2P Networking
3.1.5.1.1. Features
3.1.5.2. Client-Server Networking
3.1.5.2.1. Features
3.2. Types of Networks
3.2.1. LAN (Local Area Network)
3.2.1.1. A type of network connecting computers within a small geographical area such as a building or group of buildings
3.2.2. MAN (Municipal Area Network)
3.2.2.1. A computer network connecting multiple LANs over an area of a city
3.2.3. WAN (Wide Area Network)
3.2.3.1. A computer network connecting multiple smaller networks over very large geographical areas
3.2.3.1.1. Internet is an example
3.2.4. WLAN (Wireless Local Area Network)
3.2.4.1. A type of network consisting of computers and peripheral devices that use high-frequency radio waves to communicate with each other
3.2.5. PAN (Personal Area Network)
3.2.5.1. A type of limited-range computer network used for data transmission among various types of personal devices
3.2.6. CAN (Campus Area Network)
3.2.6.1. A type of network that interconnects multiple LANs within a limited geographical area
3.2.7. SAN (Storage Area Network)
3.2.7.1. A dedicated local network consisting of devices providing data access
