They differ in how data is sent over a communication medium, the frequency range they use, and their applications.Broadband systems use modulation techniques to reduce the effect of noise in the enviro
The dots represent the nodes in the various topologies, and the lines represent the communication links. Network topologies include the following types:
Type “netstat -a” in the command prompt and press ‘Enter’, this lists all the ports being used.
A protocol is a set of rules or algorithms which define the way how two entities can communicate across the network and there exists a different protocol defined at each layer of the OSI model. A few such protocols are TCP, IP, UDP, ARP, DHCP, FTP, and so on.

Application layer. Security protocols, such as Transport Layer Security, operate at this layer and play an integral part in ensuring network security. This is the abstraction layer that communicates directly with applications and defines how high-level apps should access the network to start a data transfer.
Ring network. Network devices are connected to two other devices on 男同网 either side through a coaxial cable or an RJ-45 cable.
Computer networks can also include multiple devices/mediums which help in the communication between two different devices; these are known as Network devices and include things such as routers, switches, hubs, and bridges.
