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:
In addition, many offices only have one printer or a few printers that are shared by everyone. Without a network, the IT department would have to connect every single computer to the printer, which is difficult to implement from a technical standpoint.
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.

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
The more complex a network is, the more vulnerable it is to attacks. In times when customers and partners have access to internal network structures via the internet, and can control various applications via web interfaces, IT employees are encountering more and more problems.…
Network: A network is a collection of computers and devices that are connected together to enable communication and data exchange.
Understanding the basics of computer networking is essential in today’s interconnected world. Networks enable the seamless exchange of information, support countless applications, and underpin the functionality of the Net.
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.
