Accepted Answer

An intranet is a private network that is only accessible to individuals within the organization. It is a secure and cost-effective way to share information, resources and applications within the organization. A wired network, extranet and virtual private network are all types of networks, but they are not necessarily restricted to internal use only. A wired network is a type of network that uses physical wires or cables to connect devices, and it can be used for both internal and external communication. An extranet is a private network that is accessible to individuals outside the organization, such as business partners or customers. A virtual private network is a network that uses public networks to create a private network. It can be used for both internal and external communication.
