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.
Response to User: The resolver stores the IP address in its cache and sends it to the user's device.

Keep Data Secure: Built-in security features like encryption and access control protect data. Additional protections like antivirus software, firewalls, and malware protection can be added to strengthen network security.
A variety of protocols and algorithms are also used to specify the transmission of data among endpoints.
The links can be configured in different ways, both physically and logically, and the network topology dictates the manner in which links and nodes relate to each other.
A signal-to-noise ratio compares the strength of a desired signal with any undesired signals created by background noise. See complete definition What is the OSI model? The 7 layers of OSI explained The OSI model (Open Systems Interconnection model) is a multilayered reference model that shows how computer systems and ... See complete definition
A computer network is a group of interconnected nodes or computing devices that exchange data and resources with each other. A network connection between these devices can be established using cable or wireless media.
