Information Technology Infrastructure Quiz

Questions and Answers

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:

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

Match the following network devices with their functions:

Router = Forwards data packets between computer networks Switch = Connects devices within a single computer network and forwards data only to its intended recipient Hub = Connects multiple Ethernet devices together, making them act as a single network segment Modem = Modulates and demodulates digital data for transmission over analog communication links

Match the following data communication terms with their definitions:

<p>Data communication = Process of sending data electronically from one point to another Data conferencing = Allows two or more users to share a common data resource either on a common computer server or their networked computers Telecommunication links = Connections provided by third-party operators for geographically distributed computer networks Interconnectivity = Ability to connect hardware, software, databases, and media to achieve connectivity between employees and stakeholders</p> Signup and view all the answers

Match the following network topologies with their characteristics:

<p>Bus topology = All devices are connected to a single central cable or backbone Star topology = Each device is connected to a central hub or switch, forming a star shape Ring topology = Each device is connected to two other devices, forming a ring Mesh topology = Every device is connected to every other device in the network</p> Signup and view all the answers

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)
