Network Communication: Flow of information among the group of members 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 channels in the organisation and the number of persons involved in the process.There can be many patterns of communication network. Function of Communication devices: The functions of communication networks include: *Providing the means for coordinating the activities of individuals, relationships, groups and other subunits within the organization. *Providing mechanisms for directing the activities of the organization as a whole. *Facilitating the exchange of information within the organization, and Ensuring the flow of information between the organization and the external environment in which it exists. Following are the different network communication devices: • NIC Adapters: NIC is Network Interface Card; this is the most important device in building network.These adapters are the most common part of computers which are used in our homes and offices.Nic is also referred to LAN, i.e. is Local area network card. • Routers: Router is intelligent device which routes data to destination computers. It helps in connecting two different logical and physical networks together. In small network server is connected to router along with clients for communication. • Hubs: If we talk about networks on larger scale hub(s) are required to build network. All computers are connected directly to the hub as hub performs as centralized device the network. When data is sent to the hub it broadcasts the data to all the ports of the hub and then it is sent to destination computer on the network • Switches: Switch is another important device when we talk about computer network on broader spectrum.It is used at the same place as hub is but the only difference between the two is that switch possess switching table with in it. Switching tables store the MAC addresses of every computer it is connected. • Gateways: As name suggests it some kind of passing through to some thing. Interestingly gateways can be software or it can also be device. Gateway device connects LAN with internet. Its basic functionality is to provide security to the network • Networking Cables: Cables are obviously used to connect communication devices with each other to form network. There different types of cables, commonly used cables are 10baseT/CAT5, coaxial cable, Ethernet and fiber optical cable. Fiber optical is the most expensive as it enables the data transfer at speed of light. Solution Network Communication: Flow of information among the group of members is communication network.

Flow of information among the group of members 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 channels in the
organisation and the number of persons involved in the process.There can be many patterns
of communication network.
Function of Communication devices:
The functions of communication networks include:
*Providing the means for coordinating the activities of individuals, relationships, groups and
other subunits within the organization.
*Providing mechanisms for directing the activities of the organization as a whole.
*Facilitating the exchange of information within the organization, and Ensuring the flow of
information between the organization and the external environment in which it exists.
