Match the following network types with their descriptions:
Match the following network types with their descriptions:
LAN = Interconnects two or more computers within a relatively small, well defined area WAN = Interconnection of two or more computers that are geographically distributed Intranet = Internal network used to share information within an organization Internet = Global system of interconnected computer networks
Match the following data communication methods with their descriptions:
Match the following data communication methods with their descriptions:
Circuit switching = Opens up a complete predetermined transmission route for uninterrupted message transmission Message switching = Data is routed based on the destination address and other parameters in the message Packet switching = Data is broken into packets and transmitted independently, allowing for efficient use of network resources Wireless networking = Connects devices using wireless signals instead of physical wires

Study Notes
Network Types
- Network types include LAN (Local Area Network), WAN (Wide Area Network), MAN ( Metropolitan Area Network), and WLAN (Wireless Local Area Network)
Data Communication Methods
- Data communication methods include Simplex (one-way communication), Half-Duplex (two-way communication, but not simultaneously), and Full-Duplex (two-way simultaneous communication)
Network Devices
- Network devices include Hub (connects devices, no routing decisions), Switch (connects devices, makes routing decisions), Router (connects multiple networks, makes routing decisions), Modem (modulates and demodulates signals), and Bridge (connects two networks, makes routing decisions)
Data Communication Terms
- Data communication terms include Bandwidth (amount of data transmitted per unit time), Throughput (actual data transferred), and Latency (delay in data transmission)
Network Topologies
- Network topologies include Bus (single cable connecting all devices), Star (central device connecting all other devices), Ring (each device connected to two neighbors), Mesh (each device connected to every other device), and Tree (combination of bus and star topologies)
