The dots represent the nodes in the various topologies, and the lines represent the communication links. Network topologies include the following types:
Mechanical switches were used so that peripheral devices could also be shared. Due to physical limitations (cable length), the devices and computers always had to be very close to each other.
OSI stands for Open Systems Interconnection. It is a reference model that specifies standards for communications protocols and also the functionalities of each layer.
Port: A port can be referred to as a logical channel through which data can be sent/received to an application. Any host may have multiple applications running, and each of these applications is identified using the port number on which they are running.
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.
We don’t have to remember all the IP addresses of each and every website. The command ‘nslookup’ gives you the IP address of the domain you are looking for. This also provides information on our DNS Server.
Adapt Quickly: Many networks are controlled by software, so changes can be made quickly through a digital dashboard. This allows traffic to be managed easily.
Devices attached to a computer network use IP addresses that are resolved into hostnames through a domain name system server to communicate with each other over the Net and on other computer networks.

Resource sharing. Enterprises of all sizes can use a computer network to share resources and critical assets. Resources for sharing can include printers, files, scanners and photocopy machines.
Network: A network is a collection of computers and devices that are connected together 男同网 to enable communication and data exchange.
Computer networks come in all shapes and sizes. Explore the seven common types of networks, along with their pros and cons.
Partial mesh network. Only some nodes connect directly to one another, while others are only connected to one or two other nodes in the network.
