Networking Concepts (Comptia Video)

A computer or server connected to a network. It can be either a client or a server.

Any device that can connect to a network, including computers, printers, routers, and switches.

A network that connects computers and devices within a limited geographical area, usually a single building or campus.

Multiple LANs combined together, even spanning multiple buildings

A network that connects devices over a large geographical area. This can be across cities, states, or even countries.

A network that connects multiple LANs together. These can be used to connect different locations or departments within a company.

A network that uses a central server to store and manage data. Clients can access data and applications on the server.

A network where there is no central server. Instead, all devices operate peer-to-peer, sharing data and resources directly with each other.

A network that connects devices over a large geographical area, often using leased lines.

A network that connects devices in a small, localized area, typically a single building or room.

A network that connects devices in a specific city or town, often used by businesses or tourists.

A network that connects devices within a campus or company, often spanning multiple buildings.

A network that connects devices within a close personal space, often using Bluetooth technology.

A communication pathway between two devices on a network, such as a cable or wireless connection.

Devices on a network that request services from a server, like computers, phones, and tablets.

Devices on a network that provide services to clients, such as web servers, file servers, and print servers.

A specialized operating system designed to provide services to clients on a network.

A standard operating system designed for individual use on a single computer, like Windows or macOS.

A device that connects multiple devices on a network and forwards data to the correct destination.

A network structure where services are provided by centralized servers that all devices access. It is used in larger organizations with thousands of devices, ensuring better security and management.

The arrangement of connections between devices in a network. It defines the flow of data and how devices communicate with each other.

A network where devices are connected to a single central cable or line, known as the bus.

A network where devices are connected in a circular loop, with data flowing in one direction.

A physical or virtual separation of resources in a network, improving security and control. Publicly accessible services are separated from internal services.

A network architecture where services are provided by centralized servers that all devices access.

The physical or logical arrangement of a network, defining how devices are interconnected.

A network topology where every device is directly connected to every other device using separate links. Offers high redundancy but is impractical for large networks due to the number of required links. Used in WANs and internet infrastructure.

A type of network topology where several devices are connected to a central hub, forming a physical star pattern. Hubs operate on a 'broadcast' system, sending data to all connected devices. This can cause performance issues and security vulnerabilities.

A type of network topology where a switch acts as the central connecting point, offering a logical star shape. Switches use MAC addresses to direct data packets efficiently, leading to improved performance and security compared to hubs.

A network topology where devices are connected in a single line, forming a physical bus pattern. All data travels along this bus, requiring a central controller to manage traffic. Common in older systems, it is less practical for newer networks due to performance limitations and security risks.

A network topology characterized by a hub as the central connecting point, where data is sent to all devices. This method creates issues such as data collisions and limited security.

The ability to expand a network's size and capacity to meet growing demands. LANs can scale to accommodate larger organizations, while WANs can connect multiple locations across continents.

The process of identifying and resolving issues within a network. Mesh topologies can be challenging because a link failure may not be immediately apparent, making troubleshooting complex.

The benefit of having multiple paths for data transmission. In a mesh topology, if one link fails, the network can re-route data through an alternate path, ensuring continued communication.

A network connection where two devices communicate directly with each other, without any intermediary devices.

A communication method where only one device can transmit at a time. Devices take turns sending and receiving data.

A communication method where devices can transmit and receive data simultaneously.

The most common network topology where all devices connect to a central device, like a switch or hub.

A central device in a star topology that forwards data between connected devices.

An older, less intelligent central device that broadcasts data to all connected devices.

The way a network topology appears to the devices connected to it, often different from the physical connections.

The actual physical connections between devices in a network.

The way a hub handles data by broadcasting it to all connected devices, regardless of the destination.

A unique identifier for each device on a network, often used in Ethernet networks.

The process of a switch learning the MAC addresses of connected devices and establishing direct connections between them.

The amount of data that can be transmitted over a network connection at a given time.

The process of reducing available bandwidth by broadcasting data to all connected devices, as done by hubs.
