Networking Fundamentals

What is a LAN?

• A LAN is a local area network, a type of network that connects computers and other devices within a limited geographic area, such as a single building or campus.

• A LAN is a large area network that spans multiple cities or countries.

• A LAN is a long-range area network that covers vast distances.

• A LAN is a limited area network that only covers a small geographic region.

What is a WAN?

• A WAN is a wide area network, a type of network that connects computers and other devices over a large geographic area, such as across multiple cities or countries.

• A WAN is a wide area network that only covers a single building or campus.

• A WAN is a wired area network that uses only wired connections.

• A WAN is a world area network that connects devices globally.

What is a client-server model?

• A client-server model is a type of network architecture in which a central server provides resources and services to client devices.

• The client-server model is a decentralized network model where all devices have equal power and decision-making abilities.

• The client-server model is a static network model where devices only communicate with each other at set times.

• The client-server model is a model where servers are only clients and clients are only servers.

What is a peer-to-peer model?

• A peer-to-peer model is a type of network architecture in which all devices have equal capabilities and can act as either clients or servers.

• The peer-to-peer model is a centralized network model where all data passes through a single central node.

• The peer-to-peer model is a hierarchical network model where some devices have more power and decision-making abilities than others.

• The peer-to-peer model is a model where peers can only communicate with servers and not with each other.

What is a switch in a network?

• Connects devices in the same network.

• A switch is a device that slows down the flow of data in a network.

• A switch is a device that connects networks together but does not direct traffic within them.

• Provides WiFi signal for laptops and mobile devices

What is virtualization?

• Virtualization is the creation of virtual versions of computer resources, such as servers, storage, and networks, that can be dynamically allocated and managed as needed.

• Virtualization is a process of physically dividing a single physical device into multiple devices.

• Virtualization is a process of limiting the functionality of devices.

• Virtualization is a process of decreasing the performance of devices.

What is cloud computing?

• Cloud computing is the delivery of computing resources over the Internet, allowing users to access and use shared resources on-demand, without having to own and manage the underlying hardware.

• Cloud computing is a method of storing data on local hard drives instead of remote servers.

• Cloud computing is a method of only allowing authorized users to access data and applications.

• Cloud computing is a method of slowing down the performance of data and applications.

What is the Internet of Things (IoT)?

• The Internet of Things (IoT) is a network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, and network connectivity, allowing them to collect and exchange data.

• The Internet of Things (IoT) is a system of data collection and analysis, not a network of interconnected devices.

• The Internet of Things (IoT) is a technology for controlling devices, not for communication between them.

• The Internet of Things (IoT) only supports wired connections, not wireless.

What is data measured in?

• Data is typically measured in bits or bytes.

• Data is measured in inches.

• Data is measured in pounds.

• Data is measured in flops

What can impact network speed and performance?

• Network speed and performance can be impacted by various factors, including network congestion, network distance, network architecture, and network security.

• The amount of memory on a computer can impact network speed and performance.

• The number of applications running on a computer can impact network speed and performance.

• The color of the network cables can impact network speed and performance.
