Communication networks are the heart of today’s internet communication and connectivity. Huge data is delivered to our devices in seconds. It has made life simple with high accessibility to almost every information under the sun . Today we shall understand about one of the key component in this system . They are nodes . Nodes are points of contact for send information to multiple destination from source .
THE THREE MAIN TYPES OF NETWORKS
1. Local Area Network (LAN): It is usually covers a small area that is restricted to a small geographic area. A computer network available only to the residents of a building can be called a LAN.
2. Wide Area Network (WAN): As the name implies, these networks cover a broad range of geographic area. WANs are used to connect LANs and other types of networks together so that users and computers can communicate with computers in other regions. An example of a WAN is the much-used and loved, Internet.
3. Metropolitan Area Network (MAN): MAN is a network that connects the users with computer resources in a geographic area that is larger than LAN but not quite as large as WAN.
COMPONENTS OF NETWORKING SYSTEM:
1. SERVER: they provide access to all the resources to the users of the network. It may be a data center , a computing system or a web service provider etc .
2.CLIENTS : Client computers are basically the users of the network, as they request and receive services from the server .
3. TRANSMISSION MEDIA : Transmission media are the facilities used to interconnect computers in a network, such as twisted-pair wire, coaxial cable, and optical fiber cable. Transmission media are sometimes called channels, links or lines.
4. SHARED DATA – Shared data are data that file servers provide to clients such as data files, printer access programs and e-mail.
WORKING OF NODES IN THE SYSTEM :
They recieve packets of information from various to deliver them to required destinations . These information are random in nature and hence nodes are equipped with probabilistic features and buffering to save the packets for queuing. This ensures that there is no buffer overflow and no information is lost . It is also possible to statistically characterize the flow of throughput.
Routing is also done for nodes based on probability theories. This is to deliver the packets to destination . Routing is the basis for accuracy.
