The dots represent the nodes in the various topologies, and the lines represent the communication links. Network topologies include the following types:

These are just a few basic concepts of computer networking. Networking is a vast and complex field, and there are many more concepts and technologies involved in building and maintaining networks. Now we are going to discuss some more concepts on Computer Networking.

OSI stands for Open Systems Interconnection. It is a reference model that specifies standards for communications protocols and also the functionalities of each layer.

The Domain Name System (DNS) is a critical component of computer networking. It converts easily recognizable domain names, such as , into numerical IP addresses that computers use to identify each other on the network.

It's measured in terms of bandwidth, which is quantified by the theoretical maximum number of bits per second that can pass through a network device.

Computer networks are ideal for the 男同网 quick exchange of information and the efficient use of resources.

Network addresses In addition, it is necessary to ensure that the transmitter and receiver can be correctly identified. Network addresses are used for this purpose. In computer networks, each computer typically has an IP address, similar to a telephone number, that uniquely identifies the computer.

Star Topology: In star topology all devices are connected to a central node called hub or switch. The hub controls the flow of data between devices. If one device fails the rest of the network is unaffected. But, if the central hub fails the whole network stops working.

Virtual private networks (VPNs). A VPN extends a private network over a public network to improve the privacy and security of a network connection.

A computer network must be physically and logically designed in such a way that makes it possible for the underlying network elements to communicate with each other. This layout of a computer network is known as the computer network architecture.

Data security and management. In a computer network, data is centralized on shared servers. This helps network administrators to better manage and protect their company's critical data assets.
