The internet is a global network that uses TCP/IP protocols to connect millions of computers worldwide.
It can include different network, such as private, public, organizational, academic, government, etc.
It allows user to communicate with each other and share massive amounts of data in various formats.
Internet is available in both modes, wired and wireless.
In wired mode, the data travels through fiber optic cables, whereas in wireless mode, the data travel through radio waves.
What is the Intranet?
An intranet can be defined as a private network used by an organization.
Its primary purpose is to help employees securely communicate with each other, to store information, and to help collaborate.
Intranet usually runs in a client/server environment where the computers are connected using local area networks.
Each computer is identified by the MAC address or an IP address, which remains unique for every computer.
Because web browsers do not depend on the platform, they are also used on Intranet to access and retrieve information from the server within the organization.
In addition to the protocols, Intranet uses a firewall to filter unwanted elements to the network and protects it from external intruders.
But most companies use customized software designed purposely for company-specific tasks.
It also includes network connectivity and the public telecommunication system, which help access and share the company's data, projects, and operations securely with the staff.
