Difference between Network and Internet

Details

What is a Network?

The network is two or more connected computer which can share resource like a printer, an internet connection, application, etc. It is a collection of computer systems and devices which are linked together using a wireless network or via communication devices and transmission media.

The network provides connectivity between computers and devices within a restricted range where only one entity is controlled or authorized to manage the entire system.

In this tutorial, you will learn

What is the Internet?

The internet is a global system which use TCP/IP protocol suite to link various types of electric devices worldwide. The internet is a collection of interconnected devices which are spread across the globe. It is a network of networks that consist of public, private, public, sales, finance, academic, business and government networks. The internet is a type of network and called network of networks.

KEY DIFFERENCE

  • Network connects thousands of PC, at one-time while the Internet connects millions of computers at one time.
  • In a network, one entity has administrative rights to manage the network whereas on the Internet, no entity controls the system.
  • Network objective is to exchange data and collaborates with peers whereas the main Internet objective is to get the knowledge and communicate over the Internet.
  • The Network is a collection of computer systems and devices that are linked together using LAN, WAN, CAN, or HAN whereas the Internet is a global system to link various types of electric devices worldwide.
Computer Network

Types of Networks:

Three types of Networks are:

1) LAN (Local Area Network):

LAN is a network that connects a small number of the system in a relatively close geographical area. E.g., a floor or nearby surrounding of a building.

2) MAN (Metropolitan area Network):

It is a communication infrastructure that has been developed in and around large cities.

3) WAN (Wide Area Network:

It is a network that connects two or more local-area networks over a large geographic distance. A WAN spans across a large geographic area, such as a state, province or country.

Why do you need a Network?

The network offers the following advantages:

Why do you need Internet?

The network provides connectivity between computers and devices within a restricted range. In this system, only one entity is controlled or authorized to manage the entire system.

History of Network

1950s -1960s:

Terminal-Oriented Computer Networks had begun which were very expensive. Therefore, time-sharing techniques were developed to allow them to be shared by many users.

1960s-1970s:

The cost of the computer dropped, and new applications emerged. It becomes essential to enable mainframe computers to interconnect and communicate with each other.

1960s – APRANET was the first real attempt of developing a network to interconnect computers over a wide geographic area

1980:
