BASIC COMPONENTS OF COMPUTER NETWORK

NETWORK

   “The interlink connection between device or node through a communication link (medium) to communicate data is called network.” 

basic component of computer network

COMPONENTS OF NETWORK

To make a network we need some component that combine together to make us able to communicate data between nodes. Component of network contain the physical component called as hardware component of network as well as the operating system and some protocol required for networking named as software component of network.

1. Hardware Component Of Network

    The Hardware components that are the physically installed devices, wires and accessories which can be seen or touch. The following components of network count as Hardware component.

i) Transmission media
    Transmission media is the channel by which the data is travel form one device to another in a network; it is the medium between the nodes in network. Transmission media may be guided like coaxial cable and optical fiber and with unguided like micro waves and radio waves.

ii) NIC(Network Interface Card)
    Network Interface Card also known as NIC, it is a hardware component that connects the computer to network a circuit board usually comes with computer system that dedicated network connection to computer. Some family of computer’s organization NIC is a mandatory part but at other side in some computer’s family we have to install NIC separately. Without this card computer can’t connect through network.

iii) Server
    Servers are the high speed high storage computers that usually offer services. Network Operating System (NOC) is specially design for this type of computer that offer services that other client can use these resources. It can be deferent type like file server that store large amount of file and database server etc.

iv) Client
    Computers that normally use by public to use network resources, client request and use the server services.

v) Peer
    Peer are those computer that can provides services in a networking and also use the resources that provide by server and other peers. This type of computer can be server and client at a time.

vi) Connecting device
    The devices that use between nodes/computer and network to binding the network and media together. Some example of connecting deices are Routers, Bridges, Hubs, Gateways and Switches etc.

2. Software Component Of Network

Software components of hardware are those software and protocol that make the hardware communicate-able in order to build a reliable networking system

i) NOS(Network Operating System)
    Like the other Operating system the Network Operating System is used in server to facilitate workstation in network in order to share data and information.

ii) Protocol(OSI/TCP IP model ) 
    OSI and TCP IP models are the protocol of networking which tells about the rules which is defines to communicate the nodes in a network.
