Networking Step Revision

Select the description of a data packet.

• A large collection of files bundled together for storage on a computer's hard drive.

• A visual representation of data, like a chart or graph, used to display information.

• A piece of data sent over a network. Messages have to be broken down into binary data packets before they are transferred.

Select the purpose of an Ethernet cable.

• A fast, secure way of transmitting data using a wire.

• To wirelessly transmit data between devices using radio waves.

• To provide electrical power to a computer or other electronic device.

Select the advantage of using fibre optic cables.

• They are less expensive and easier to install than traditional copper cables, and are more durable.

• They can carry electrical power and data signals simultaneously, simplifying network setups.

• Cable that carries data transmitted as light.

Select the statement that describes the term internet.

• A worldwide collection of computer networks. The term ‘internet’ refers to the network infrastructure, not the content stored on it.

• A single, large computer that stores all the world's information.

• A type of software used to create websites and online games.

Select the meaning of the abbreviation LAN.

• Linear Access Node

• Large Application Number

• Local Area Network

Select the statement that describes the term Network.

• Large Application Node.

• Linear Algorithmic Numerator.

• Two or more computers (or other electronic devices) that are connected together for the purpose of communication. They are connected by a wired medium such as cables, or by a wireless medium. Each network will adopt a topology.

Select the statement that describes the term topology.

• Topology is the study of geometric properties and spatial relations unaffected by the continuous change of shape or size of figures.

• Topology refers to the arrangement of elements in a particular order or sequence.

• Topology is a branch of mathematics concerned with the properties of space that are preserved under continuous transformations.

• Topology is the study of celestial bodies and their movements.

Select the statement that describes why digital devices will have a NIC.

• To regulate the device's power consumption and prevent overheating.

• Provides a method of connecting to a network. A NIC offers an interface port for a wired connection. A wireless NIC provides a radio transceiver for connecting wirelessly.

• To store and process data, acting as the device's main memory.

Select the statement that describes the purpose of a router.

• To amplify Wi-Fi signals within a home or office.

• To store data and files for multiple users on a network.

• Used to send data packets across the internet. Routers work by collecting knowledge of available routes to transmit data. They then determine the most suitable route for sending data. Use IP addresses to route data packets.

Select the statement that describes the purpose of a Server.

• A computer that holds data to be shared with other computers. Servers require server software.

• To act as a personal computer for individual users.

• To solely manage the physical wiring of a network.
