Computer Network a collection of computers or devices that are linked together
Yes, a computer network is a collection of computers or devices that are linked together. These devices can exchange data and resources with each other. The connection between these devices can be established using cable or wireless media. Once a connection is established, communication protocols are used to exchange data between the networked devices.
The first example of a computer network was the Advanced Research Projects Agency Network (ARPANET). This packet-switched network was created in the late 1960s by ARPA, a U.S. Department of Defense agency. ARPANET was used to connect computers at universities and research institutions.
Today, there are many different types of computer networks. Some of the most common types include:
Local area networks (LANs): LANs are small networks that connect computers in a limited physical area, such as an office, school, or home.
Metropolitan area networks (MANs): MANs are larger networks that connect computers in a city or metropolitan area.
Wide area networks (WANs): WANs are the largest type of network, and they connect computers all over the world.
The internet is a global WAN that connects millions of computers. It is the most well-known and widely used computer network in the world.
Computer networks are essential for communication and collaboration in today's world. They allow people to share information, work together on projects, and access resources from anywhere in the world.
