Computer Network is a system that connects two or more two computing devices for sharing information between them. I will give you details about computer networks, types, and their components.
Basics of Computer Network
Computer Network is basically a system that connects computing devices to each other for transferring information. That includes every device connected to a server. These devices are connected normally by physical wires but sometimes they can be wireless as well.
The working network called ARPANET was created in the 1960s and was funded by the U.S Department of Defense. Government researchers need to share information but at that time computer was too big and also difficult to move. To fix this issue this network was created. Today, The whole world become a global village. Now a lot of networks are created, which connect billions of devices to the network.
Components of a Computer Network
Computer Network is built with two blocks: Network devices and links. The links connect two nodes with each other. The way these links carry information by communication protocols. The communication endpoints are called ports.

Network devices are computer devices is to are linked to a network. Some network devices are given below.
Computer, and Mobile devices: These are Low and High-end devices that directly access users. For example, getting email originates from the mailing application on pc or mobile.
Servers: Storage servers where the main data is saved. All the requests and specific tasks to the servers.
Routers: Routing is the process of selecting the network path through which the data packets transfer. This thing adds efficiency to a large network.
Links
Links are the transmission media which have two types
Wired: Wired technology used in the network includes cable, Phone lines, and optical fibers. Light pulses are carried out in Optical fibers.
Wireless: As I told you earlier, a Network can also be wireless. The network can establish radio. This kind of transmission is known as "Wireless". For example communication satellites, Cellular networks.
Types of Computer Networks
Computer networks are based on different criteria, transmission medium, network size, and organizational intent. Types of networks are given below.
- Nanoscale Network: This network enables communication between minuscule sensors.
- Personal Area Network: Personal Area Network refers to a network used by one person to connect multiple devices like laptops to scanners, and PC to printers.
- Local Area Network: This network connects devices limited to geographical or local areas, such as offices, and schools.
- Wide Area Network: Wide area network provides services to larger cities and countries.
- Virtual Private Network: VPN is an overlay private network that is top of the public network or one-step higher.
- Cloud Network: A cloud network which is providing Cloud services of different types.
- Storage Area Network: Storage Area Network is facilitating block-level data storage.
- Conclusion
A successful network boost productivity, Security with the least overhead costs. A network creation, Requires business input, especially in the initial stages. Network Management also involves workflows and growing with evolving technologies.
