A computer network is an infrastructure that enables multiple computers and devices to communicate and share resources, such as files, printers, internet connections, and more. The primary goal of a computer network is to facilitate the transmission of data and information between the various components of the network.

Here are some key points to understand what a computer network is:

  1. Device Communication: A network allows multiple devices, such as computers, servers, printers, routers, and connected devices, to communicate with each other.
  2. Resource Sharing: Resources like files, printers, internet connections, and applications can be shared within the network, facilitating collaboration and access to information.
  3. Data Transmission: Networks enable the transfer of data between connected devices, whether locally (within the same physical location) or remotely (across the internet).
  4. Network Topologies: Networks can have different topologies, such as star, bus, ring, mesh, each with its own advantages and disadvantages.
  5. Communication Protocols: Protocols define the rules and conventions for communication between network devices. Examples of protocols include TCP/IP, HTTP, and FTP.
  6. Local Area Networks (LAN) and Wide Area Networks (WAN): Local Area Networks cover a limited geographical area, such as an office or a home, while Wide Area Networks can cover larger distances, interconnecting geographically dispersed sites.
  7. Network Security: Network security is crucial to protect data from unauthorized access. Firewalls, security protocols, and access management are essential elements of network security.
  8. Internet: The internet can be considered the largest global computer network, interconnecting millions of networks worldwide.

In summary, a computer network enables connectivity and collaboration between devices, facilitating information sharing and efficient computer operations.
