What is a network?
A network is a collection of devices such as computers, printers, and servers that are connected together to share resources and communicate with each other. Networks can be physical, such as a set of computers and devices that are physically connected through cables, or they can be virtual, such as a group of computers that are connected through the internet.
The main benefits of a network include:
Resource sharing: Devices on a network can share resources such as printers, storage devices, and software applications.
Communication: Devices on a network can communicate with each other, allowing for collaboration and data sharing.
Centralized management: Networks can be centrally managed, making it easier to monitor and control the network and its resources.
Improved security: Networks can implement security measures to protect against unauthorized access and data breaches.
There are several types of networks, including:
Local Area Network (LAN): This is a network that covers a small geographical area, such as a home, office, or school.
Wide Area Network (WAN): This is a network that covers a large geographical area, such as a city, country, or even the world.
Wireless Network: This is a network that uses wireless technologies such as Wi-Fi to connect devices.
Cloud Network: This is a virtual network that is hosted in the cloud, allowing devices to connect and share resources over the internet.
