Network and communication

Computer network

This network of communication follows the organisational hierarchy and chain of command. Network structure[ edit ] Network topology is the layout or organizational hierarchy of interconnected nodes of a computer network.

This breaks the network's collision domain but maintains a unified broadcast domain.

An example of a WAN is the much-used and loved, Internet. Shared printers and other peripherals - Shared printers and peripherals are hardware resources provided to the users of the network by servers. At its core, the protocol suite defines the addressing, identification, and routing specifications for Internet Protocol Version 4 IPv4 and for IPv6, the next generation of the protocol with a much enlarged addressing capability.

Under star communication network all members of the group communicate with each other and exchange information. There are many different kinds of servers, and one server can provide several functions. WANs are used to connect LANs and other types of networks together so that users and computers can communicate with computers in other regions.

Overlay networks have also been proposed as a way to improve Internet routing, such as through quality of service guarantees to achieve higher-quality streaming media.

Free-space optical communication uses visible or invisible light for communications. The signal is retransmitted at a higher power level, or to the other side of an obstruction, so that the signal can cover longer distances without degradation. Network Operating System - The network operating system is a program that runs on computers and servers, and allows the computers to communicate over the network.

Topics include wireless network components, design, security, troubleshooting, and regulation. It is formal network. Overlay network[ edit ] A sample overlay network An overlay network is a virtual computer network that is built on top of another network.

There are three main types of networks: This can cause a propagation delay that affects network performance and may affect proper function. Therefore it is known as circuit network.

Switches[ edit ] A network switch is a device that forwards and filters OSI layer 2 datagrams frames between ports based on the destination MAC address in each frame.

The devices that transmit or receive this data, such as a phone or a computer, are referred to as nodes. For example, every Web page that you receive comes as a series of packets, and every e-mail you send leaves as a series of packets.

Servers provide access to network resources to all the users of the network. There are three main types of networks: With many technologies, such as bus networks, a single failure can cause the network to fail entirely.

Network helps managers to establish contacts in different patterns through communication flows. This network can be used in a variety of ways. The pattern of contacts among the members of the organisation and flow of information among them is communication network.

With Internet, computer, and telephone networks, businesses can allocate their resources efficiently.

Prerequisites Before you start proceeding with this tutorial, I'm making an assumption that you are already aware about basic computer concepts like what is keyboard, mouse, monitor, input, output, primary memory and secondary memory etc.

This network is a must for group communication or where teamwork is involved. They may be connection-oriented or connectionlessthey may use circuit mode or packet switchingand they may use hierarchical addressing or flat addressing. In general the more interconnections there are, the more robust the network is; but the more expensive it is to install.

Switch - Switch is a telecommunication device grouped as one of computer network components. While the role of ATM is diminishing in favor of next-generation networksit still plays a role in the last milewhich is the connection between an Internet service provider and the home user.

The pattern of contacts among the members of the organisation and flow of information among them is communication network. Network helps managers to establish contacts in different patterns through communication flows.

The network depends upon the magnitude of the organisation, nature of communication [ ]. A wheel network is a style of communication where the leader is the only one to receive or give communication.

The leader, usually the supervisor or owner in the company, is like the bright light. A personal area network (PAN) is a computer network used for communication among computer and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and even video game consoles.

Networking and Communication "Check the reviewed one below". What is Networking and Communication? Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data.
