Networking
In simple terms, a network is a group of interconnected devices that can communicate with each other. This network can be physical, such as computers connected by cables or wireless devices connected through Bluetooth or Wi-Fi. Networks can be used for many purposes, such as sharing files, accessing the internet, or communicating with other devices.
There are two types of networks: active and passive. Active networks are those that are constantly sending and receiving data, while passive networks are those that only receive data. On the other hand, passive networks are used for applications where data does not need to be sent immediately, such as downloading files or streaming video.
An active network is an electronic network with active components such as amplifiers, routers, repeaters, switches, and hubs to transmit data between devices. These active components enhance the signals that pass through the network, ensuring they reach their intended destination without losing quality or strength.
Active networks are commonly used in larger businesses, universities, and government organisations. Examples of Active Networks include LANs (Local Area Networks), WANs (Wide Area Networks), and MANs (Metropolitan Area Networks).
However, the downside of an active network is that it is more complex to set up and maintain than a passive network. The active components require power, which adds to the overall cost of the network. Moreover, active networks are more vulnerable to failure due to the number of components involved. Despite these drawbacks, an active network is a powerful tool providing reliable and efficient connectivity for various applications.
